采用分期播种和定穗观察的方法研究了不同气候因子对金优组合结实率的影响。结果表明,在相同气候条件下,金优组合与对照汕优、威优组合相比,结实率没有明显差异;对不良气候条件的抗逆能力相当。同时还得出,影响杂交稻结实率的主要气候因子是灌浆结实阶段的日平均温度和抽穗扬花及灌浆结实阶段的降雨量
The effects of different climatic factors on the seed setting rate of Jinyou were studied by staged sowing and fixed panicle observation. The results showed that under the same climatic conditions, the Jinyou combination had no significant difference in seed setting rate compared with the control Shanyou and Weiyou combinations, and had the same ability to resist adverse weather conditions. At the same time, we also conclude that the main climatic factors that affect the seed setting rate of hybrid rice are the daily average temperature of grain-filling and the rainfall during heading and flowering and grain-filling
