水稻开花结实期间,强光适温是丰产的重要环境因素。早稻生产既要注意使减数分裂期避过“五月寒”、抽穗开花期避过梅雨季节,又应慎防高温伤害。现就高温对水稻开花结实影响的一些试验观察,谈谈生产上怎样防止高温伤害,确保水稻高产。一、早稻开花期的高温伤害国际水稻研究所的研究表明,高温对结实率影响最大的时刻在干开花当日.本研究以红
During the flowering and fruiting of rice, the suitable light temperature is the important environmental factor of high yield. Early rice production should pay attention not only to avoid the meiosis during the “May cold” heading season flowering to avoid the rainy season, but also should beware of heat damage. Now on the high temperature on rice flowering strong impact of some experimental observation, talk about how to prevent high-temperature injury in production to ensure high-yielding rice. First, the early rice flowering period of high temperature injury International Rice Research Institute showed that the high temperature on the seed setting rate of the moment in the dry flowering day.This study with red
