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.

Methods From 2021 to 2022, the Utah model, the 7.2°C model and the 0-7.2°C model were applied to the six varieties of sweet cherries cultivated in Huludao City, Liaoning Province, namely Jiahong, Hongdeng, Mingzhu, American Red, Sand Honey Bean and Meizao, as well as Jiangxi The CR of four varieties of sweet cherries cultivated in the Fuzhou region, namely Sand Honey Bean, Mingzhu, Jiahong and Meizao, were estimated. Results For the sweet cherry varieties tested in the Huludao area, the estimated CR of the Utah model ranged from 469 to 564.5 C.U. The estimated CR of the 0-7.2 °C model ranged from 334 to 442 h. The estimated CR range is between 710 and 1218 h; for the sweet cherry varieties tested in Fuzhou, the estimated CR range of the Utah model is between 261.5 and 525 C.U. The estimated CR of the 0-7.2 °C model The estimated CR ranged from 98 to 301 h, and the estimated CR of the 7.2 °C model ranged from 105 to 328 h. For the sweet cherry varieties tested in the Huludao area, the estimated CR of the Utah model ranged from 469 to 564.5 C.U. The estimated CR of the 0-7.2 °C model ranged from 334 to 442 h. The estimated CR range is between 710 and 1218 h; for the sweet cherry varieties tested in Fuzhou, the estimated CR range of the Utah model is between 261.5 and 525 C.U. The estimated CR of the 0-7.2 °C model The estimated CR ranged from 98 to 301 h, and the estimated cooling capacity of the 7.2 °C model ranged from 105 to 328 h. Conclusion There is a big difference in the CR of the same variety of sweet cherries in the two regions. The Utah model estimated the difference is the smallest, and the preliminary judgment is more suitable for the comparative study of the CR of sweet cherries in different regions.

The conclusions are as follows：normal temperature milk still plays a dominant role in liquid milk market due to its low requirements for transportation and storage conditions. However,with the gradual improvement of the construction of national cold chain distribution system,the consumption proportion of low temperature milk will continue to increase and it is expected to become the dominant force in liquid milk market. In the future,we should further tap the consumption potential of township market,reduce the dependence on imported dairy products,and promote the healthy and sustainable development of dairy industry.

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.

Exploration and Application of Big Data Technology in Pork Price Prediction and Regulation JIN Yuze, JIA Xinwei, LAI Wangfeng, ZHOU Hongli, CHEN Naihe, LI Tao Journal of Agricultural Big Data    2023, 5 (1): 126-134.   DOI: 10.19788/j.issn.2096-6369.230121 Abstract （1003）   HTML （48）    PDF（pc） （438KB）（640）       Knowledge map    Save China is a country of large hog production and pork consumption. Fluctuations in pork prices directly affect the interests of hog farmers and residents' diets. Prediction of the future trend of pork prices and scientific control of pork prices plays an important and practical role in promoting the stable and healthy operation of hogs and pork industry of China. This article studies the national pork market price trend. Firstly, pork supply prediction model based on the number of live hog and breeding sows is built according to the biological cycle and continuity features of hog production, which can predict pork production in the next 10 months. Secondly, taking advantage of the obvious seasonal cycle fluctuations in pork demand caused by my country's pork consumption habits, the STL time series decomposition method is used to decompose the monthly seasonal fluctuation trend from the pork transaction data to predict the monthly pork demand. Thirdly, based on the law of supply and demand in the pricing model, the relationship model of the pork price and the ratio between pork supply and demand is constructed to predict pork price in the next 10 months and calculate the price of pork supply and demand equilibrium. The relative error of pork price prediction is about 10% by using pork-related data from the Agricultural Products Market Information Platform system of the Ministry of Agriculture and Rural Affairs in 2022. When the estimated future pork supply and demand deviates, the model can adjust the pork supply by regulating the number of breeding sows, the import volume and the delivery volume, thereby regulating the future pork price trend. This study provides ideas and methods to adjust future pork price trends by adjusting the core factors that affect pork supply. This study aims to assist relevant government departments in properly and timely regulation of pork supply on the basis of scientifically predicting pork supply and demand and future price trends, so as to balance the supply and demand of pork and maintain the price of pork within a reasonable range of balanced supply and demand.
