目前国内多利用水稻社会产量,统计分析产量高低与气象条件关系,建立产量气象预测预报模式,效果是比较好的。但从生产的要求来看,还必须不断监视和预测气象条件对穗数、粒数、粒重的变化,及时采取相应措施,充分利用有利的天气、气候条件,克服或减少气象灾害的影响,夺取高产稳产。因此,我们认为研究水稻穗数、粒数、粒重及产量与气象条件的关系是很必要的。材料与方法利用我站早稻广选3号(中熟种)、桂 At present, the domestic use of rice production more than the community, statistical analysis of the output level and the relationship between meteorological conditions, the establishment of yield meteorological forecasting model, the effect is better. However, from the perspective of production requirements, it is also necessary to constantly monitor and predict the changes in the number of spikes, grain numbers and grain weights of meteorological conditions and take timely and appropriate measures to make full use of favorable weather and climatic conditions to overcome or reduce the impact of meteorological disasters, To seize high and stable yield. Therefore, we think it is necessary to study the relationship between rice panicle number, grain number, grain weight and yield and weather conditions. Materials and methods I use the station early rice Guangxuan No. 3 (Medium cooked), Gui
