    Agricultural pests and diseases pose a serious threat to crop yield and quality, making accurate and efficient detection and identification of pests and diseases crucial in agricultural production. In this paper, we propose a comprehensive agricultural pests and diseases dataset, which includes agricultural pest detection dataset, agricultural disease detection dataset, agricultural disease classification dataset, and rice phenotype segmentation dataset. By collecting and curating data from public sources and academic papers, we ensured the diversity and representativeness of the dataset. Rigorous quality control and validation measures were implemented during the data filtering, cleaning, and annotation processes to ensure the accuracy and reliability of the dataset. This dataset can be used for agricultural pest and disease recognition, as well as rice phenotype identification and other agricultural visual tasks. It provides valuable resources for agricultural pest and disease research and contributes to the sustainable development of agricultural production.

    ZHAN ZiSen, ZHANG XiaoHeng, CHEN Bo
    Journal of Agricultural Big Data    2023, 5 (4): 110-117.   DOI: 10.19788/j.issn.2096-6369.230414

    General Secretary Xi Jinping has pointed out that "the prosperity of industries is of paramount importance for rural revitalization." The Cost-Benefit Survey of Agricultural Products records information on inputs, outputs, and returns related to agricultural products, serving as the foundation for macroeconomic regulation and price management by government departments. In the new era and on the new journey, this dataset will play an even greater role in advancing the rural revitalization strategy. A large number of literature analyze the situation of China’s agricultural input factor use, productivity, cost and profit based on this dataset, but the introduction of details such as the sample selection of the dataset, the collection process, and the connotation of the relevant indicators needs to be enhanced. Therefore, this paper primarily compiles cost-benefit survey data for three types of grains, including early-season rice, mid-season rice, late-season rice, japonica rice, wheat, and maize, from 2005 to 2017 in 31 regions, forming a comprehensive dataset. This paper provides an introduction to the background, data collection methods, primary content of the data, and its implications and values. The data is collected by using a stratified random sampling procedure to improve the representativeness. The cost and profit data of rice farms contains the farm size, yield, output value, pesticide cost, fertilizer quantity and cost, seed quantity and cost, irrigation cost, labor quantity and cost, and land cost on per unit area. Relevant scholars can not only use the data to analyze the input-output situation of China's agricultural products, but also draw on the sampling method and quality control experience of the data.

    Theory and Engineering Technology Implementation of Artificial Intelligence Retrieval Paradigm for Parameters of Remote Sensing Based on Big Data
    MAO KeBiao, YUAN ZiJin, SHI JianCheng, WU ShengLi, HU DeYong, CHE Jin, DONG LiXin
    Journal of Agricultural Big Data    2023, 5 (4): 1-12.   DOI: 10.19788/j.issn.2096-6369.230401

    In order to solve the "black box" problem of artificial intelligence application in geophysical parameter retrieval, and make artificial intelligence applications have physical significance, interpretability, and universality, the theory and technology of deep learning coupling physical and statistical methods are gradually being developed in various disciplinary fields. This study summarizes the author's more than 20 years of relevant research, and presents the artificial intelligence inversion paradigms and judgment conditions for remote sensing parameters based on the induction and deduction of the theory and judgment conditions of artificial intelligence geophysical parameter inversion paradigms. At present, a common problem encountered in many studies is that many artificial intelligence parameter retrieval uses theoretical simulation data to achieve high retrieval analysis accuracy, but the actual application retrieval accuracy is not ideal. Therefore, deep learning how to couple physical and statistical methods has become an urgent engineering and technical challenge that needs to be addressed. We will take passive microwave soil moisture and surface temperature retrieval as an example to illustrate that the accuracy of the physical model itself still needs to be greatly improved, or the simulated data only represents a small portion of the actual situation. We believe that there are significant limitations in using only physical models to simulate data for direct retrieval, and high-precision multi-source statistical data must be supplemented. At the same time, we can also improve the physical model by directly using deep learning to simulate data training and testing with actual data to verify the gap between the physical model and the actual situation, determine the errors of the physical model, and thus improve the physical model. Statistical methods are the most intuitive description of human beings, while physical methods summarize and generalize statistical methods. However, information or energy transmission in the real world is transmitted in quantum form, and many physical models have made many simplifications without depicting real physical phenomena well. Different neurons in deep learning are more suitable for describing and expressing the transmission methods of quantum information. Understanding the real world through calculus quantum information flow requires improving our cognitive thinking. How to collect data that meets the real situation (quantum information or energy transmission) is very important. We can fully utilize physical logic reasoning to construct physical formulas and statistical methods, and use big data thinking mode to improve the accuracy of geophysical parameter inversion under the guidance of paradigm theory and judgment condition framework. Proving through physical logic reasoning that the input variable can uniquely determine the output variable is a fundamental condition for forming a physically meaningful, interpretable, and universal retrieval or classification or prediction paradigm. Controlling the quality of collected data from the perspective of quantum information (energy) transmission is the key to achieving high-precision inversion engineering and technology for geophysical parameters. Improving the cognitive understanding of quantum information flow in calculus and identifying the limitations of physical models are of milestone significance for achieving high-precision inversion in artificial intelligence.

    As grain pests cause a major post-harvest loss in stored grains, early detection and monitoring of grain pest activities become necessary for applying appropriate actions to reduce storage losses. With the development of artificial intelligence, image detection methods based on deep learning have been widely used in agriculture. However, current research in stored grain pest detection is relatively limited. The quality of the dataset will determine the level of knowledge that deep learning models can learn. Therefore, constructing a specialized dataset for grain pest detection and counting is of great significance. The proposed dataset GrainPest includes 500 original images of grain insects, 500 pixel-level saliency annotation images, 420 files with insect bounding boxes and 500 entries of pest counts. The data set covers various grain pests such as corn weevil, wheat moth, grain beetle, and corn borer, as well as different types of grain backgrounds such as wheat, corn, and rice. Due to the fact that many grains are not infected with pests, the GrainPest also includes 80 pure grain background images without any pest, which bring more challenge for saliency detection. The GrainPest provides a benchmark dataset to promote the research of saliency detection, object detection, and pests counting in stored grains, and the work will provide support for reducing grain storage losses and ensuring food security.

    Timely and accurate acquisition of cropland spatial distribution data is of great significance for agricultural production management, planting structure adjustment and food security. In this study, three northeastern provinces (Heilongjiang, Liaoning and Jilin) were selected as the research area. Based on massive Sentinel-2 data, a 12-month Normalized Difference Vegetation Index (NDVI) dataset of cropland and non-cropland samples in a specific year was established in each province. The Google Earth Engine remote sensing computing platform was used to conduct supervised classification according to the difference characteristics of NDVI between cropland and non-cropland samples, and the spatial distribution data set of cropland resources with 10 m spatial resolution in the three northeastern provinces during 2020-2022 was obtained. The data set is an update of the latest available cropland resource data set, which can provide data support and scientific services for the scientific protection of phaeozem in Northeast China, the implementation of the strategy of "storing grain in land, storing grain in technology" and the guarantee of food security.

    As an important policy to strengthen and benefit agriculture, the agricultural machinery purchase subsidy policy has a profound impact on many parties, such as new agricultural business entities, agricultural production, and the agricultural machinery industry. Through the collection of national agricultural machinery purchase and subsidy data, we can grasp the differences and trends in the purchase of agricultural machinery in various regions. We can then reasonably assess the impact of the policy, adjust the policy objectives and content, promote the healthy development of the agricultural machinery market, and better assist the construction of a strong agricultural country. At present, the Department of Agriculture and Rural Affairs of each province in China, through the information disclosure column of agricultural machinery purchase subsidies, releases data related to agricultural machinery purchase in real time. Through network crawling and processing, this dataset covers the subsidy data on the purchase and application of agricultural machinery in 23 provinces (autonomous regions and municipalities directly under the central government) such as Beijing, Tianjin, Shanxi, etc. in 2021-2022, totaling 222,6229 items. This dataset can be used to analyze the characteristics and differences of the purchase of agricultural machinery and the subsidy distribution in different regions, and provide a data basis for related scientific research and management decision-making.

    In order to explore the relationship between the yield of qualified frozen semen and serum biochemical indexes of bulls at different ages, as well as the effect of aging on the physiological indexes of bulls at different ages. Eventually, the stud bulls were screened more accurately by serum biochemical indicators. Blood samples were collected from 10 Simmental bulls in spring for two consecutive years, some serum biochemical indicators were detected, and the results of frozen semen production were compared and analyzed. The results showed that semen density, qualified frozen sperm yield, serum aspartate aminotransferase and abdominal insulin levels decreased significantly with age (P<0.01). Serum androstenedione, dehydroepiandrosterone, testosterone, and serum γ-glutamyltransferase were significantly increased in both high-yield and low-yield groups, while serum zinc and serum alkaline phosphatase were significantly increased in low-yield group (P<0.01). The serum levels of copper and magnesium in the high and low yield groups increased significantly (P<0.05). The levels of serum total protein and serum uric acid decreased significantly (P<0.05). Therefore, it is necessary to pay attention to the daily health management of breed bulls, timely supply the necessary trace elements, and reasonably arrange the service age of breed bulls to give full play to the breeding potential of breed bulls.

    Mangroves are distributed in the tropical and subtropical coastal intertidal zones, playing a critical role in the global carbon cycle and providing service value for ecological and ecological economic development. But with the development of human activities and the deterioration of the natural environment, mangrove resources have sharply decreased. Using Landsat images of 2000, 2005, and 2010, and Sentinel-2 images of 2015 and 2020, through decision tree classification and object-oriented classification methods, combined with field surveys, the study extracts the spatial distribution and area of mangroves each year, and produces the spatial distribution dataset of mangroves in Qi'ao Island from 2000 to 2020. The article dataset can analyze the spatial dynamic evolution of mangroves, providing important references for scientific research such as the dynamic changes of mangroves on Qi'ao Island and the evaluation of ecological environment quality; providing decision-making support for the protection, restoration, and management of mangrove wetlands; and providing basic data support for environmental monitoring in Zhuhai and Guangdong Province.

    Improving the efficiency of agricultural production and optimizing the problems in agricultural production through information technology is crucial for the development of agriculture in China. At present, the development of information technology has generated massive amounts of data, which are mostly distributed on the Internet in fragmented and unstructured forms. Especially in the domain of agriculture, using traditional search engines for information retrieval is difficult to efficiently and accurately obtain valuable agricultural information, often requiring a lot of time and effort to collect and organize secondary data from massive unorganized data. To address the above issues, this paper utilizes web crawler technology to mine data from publicly available agricultural websites. Through automatic or semi-automatic data cleaning, denoising, and other processes, unstructured data are recombined into structured data, which is ultimately stored in the form of a knowledge graph. The dataset for constructing agricultural knowledge graph includes item data for 11 agricultural categories, such as grain crops, cash crops, fruits, vegetables, etc. Specifically, it includes 461 types of grain crops, 2 208 types of cash crops, 1 294 types of fruits, 257 types of vegetables, 118 types of edible fungi, 1 161 types of flowers and trees, 142 types of aquatic products, 113 types of pesticides, 1 605 types of crop diseases and pests, 519 types of veterinary drugs, and 603 types of Chinese herbal medicines, totaling 8 481 subcategories. The agricultural knowledge graph constructed based on this dataset has 90 508 triplets, which can provide basic data support for the development of human-machine interactive intelligent applications such as agricultural knowledge Q&A and recommendation systems. Meanwhile, integrating agricultural knowledge graph into generative large language models can help achieve more efficient and accurate information retrieval and intelligent decision-making in vertical domains.

    [Objective] To understand the effect of propylene glycol on the contents of glucose and ketone bodies in plasma of postpartum dairy cows and the residual situation of propylene glycol in milk.[Method]Eighteen multiparous cows with expected date of delivery within 5~20 d were randomly divided into 3 groups.The control group was not fed with propylene glycol,and the experimental group was fed with propylene glycol 500 g/ head within 2 hours after delivery,and the experimental group was fed with propylene glycol 300 g/head within 2 hours after delivery. The cattle feeding management was carried out according to the field procedures. After oral administration,milk samples were taken three times a day,and tail vein blood was collected on an empty stomach the next morning. The contents of propylene glycol in milk,glucose and ketone bodies in plasma were determined. [Result] The content of propylene glycol in milk reached the highest within 8 h after oral administration,and decreased gradually at 16 h and 24 h. No propylene glycol was detected at 32 h.At each time point,the content of propylene glycol in milk of experimental group 1 was higher than that of experimental group 2.The plasma glucose content in the experimental group was higher than that in the control group. The plasma glucose content in the experimental group was 3.49 μmol/mL,that in the experimental group was 3.28 μmol/mL,and that in the control group was 2.07 μmol/mL. Propylene glycol had a significant effect on the plasma glucose content(P<0.05),but the plasma glucose content in the experimental group was higher than that in the experimental group,but the difference was not significant(P>0.05).The plasma ketone body content in the experimental group was lower than that in the control group. The plasma ketone body content in the experimental group was 1.14 μmol/mL,the plasma ketone body content in the experimental group was 1.47 μmol/mL,and the plasma ketone body content in the control group was 3.20 μmol/mL.Propylene glycol significantly reduced the plasma ketone body level(P<0.05).The plasma ketone bodies in test group 1 were lower than those in test group 2,and the difference was not significant(P>0.05).[Conclusion] After drinking propylene glycol,the residual amount of propylene glycol in milk is extremely low,which has no influence on the quality and safety of milk. Propylene glycol can significantly increase plasma glucose content,reduce ketone body level and improve the negative energy balance of dairy cows.The dosage of 500 g group/head is better than that of 300 g group/head.
