长沙地区早稻产量定量预报模式研究

作物产量预报是气象为农服务的重要课题。产量变化除受生产力水平包括耕作制度、管理措施、水利条件、肥料和良种等因素及政策因素的影响外,还与一个地区的天气气候条件密切相关。利用历年水稻单产资料,对影响早稻产量的主要气象条件进行分析研究,并建立了早稻产量预报模式。

Quantitative Prediction Model for Yield of Early Rice in Changsha Region

Prediction of crop yield is one of the important tasks for meteorology services agriculture.The variation of yield is not only impacted by productivity level(cropping system,management measures,conditions of water conservancy,fertilizers and improved variety) and policies,but also impacted by climatic condition in a region.Using the unit yield data of rice in previous years to analyze the main climatic conditions impacted the yield of early rice,then,a prediction model for yield of early rice was established.
