水稻生长模型数据

模拟水稻生育信息（亩均产量潜力、叶面积指数、地上部干物质重），以产量为指标，反映水稻生长状况。当产量不够理想需要调整用水和用肥时，种植户可通过输入未来用水、用肥数据，进行产量预测，帮助种植户评估灌溉和用肥计划的合理性。1、数据采集：通过业务系统采集水稻品种、播种时间、种植密度、化肥用量数据；通过对接电磁流量计设备、连接田间灌溉水量数据。
2、数据处理：运用水稻品种、播种时间、种植密度、灌溉用水量、氮肥用量等原始数据，基于oryza2000进行计算，输出亩均产量、叶面积指数、地上部干物质等结果值。模拟水稻吸收CO2的速率，以及模拟水稻呼吸作用和生长速率。同时不断调整模型参数进行模型训练，最终得到水稻生长模型。
3、数据应用：产前，通过调整种植时间、密度、肥料运用等信息进行产量模拟，帮助种植户选出适合的种植策略，安排种植计划；产中，通过对接电磁流量计设备，连接田间灌溉水量数据，模拟水稻生育信息（亩均产量潜力、叶面积指数、地上部干物质重），以产量为指标，反映水稻生长状况。

This dataset simulates rice growth information including per-mu yield potential, leaf area index (LAI), and above-ground dry matter weight, using yield as the indicator to reflect rice growth status. When the actual yield is unsatisfactory and water and fertilizer adjustments are required, growers can input future water and fertilizer application data to perform yield prediction, helping them evaluate the rationality of irrigation and fertilization plans.
1. Data Collection: Collect rice variety, sowing date, planting density and fertilizer consumption data via the business system; connect with electromagnetic flowmeter equipment to obtain field irrigation water volume data.
2. Data Processing: Use raw data such as rice variety, sowing date, planting density, irrigation water volume and nitrogen fertilizer application rate for calculations based on Oryza2000, and output results including per-mu yield, leaf area index and above-ground dry matter. Simulate the CO2 absorption rate of rice, as well as rice respiration and growth rates. Meanwhile, continuously adjust model parameters for model training, and finally obtain the rice growth model.
3. Data Application: Pre-planting stage: conduct yield simulation by adjusting planting time, density, fertilizer application and other relevant information, helping growers select suitable planting strategies and arrange planting plans; Mid-growing stage: connect with electromagnetic flowmeter equipment to obtain field irrigation water volume data, and simulate rice growth information including per-mu yield potential, leaf area index and above-ground dry matter weight, using yield as the indicator to reflect rice growth status.
