摘要:
为了降低低温对水稻生产造成的损失，以水稻品种龙稻5号和东农428为材料，采用盆栽种植方式于孕穗期进行低温处理，研究孕穗期低温对水稻空壳率的影响。结果表明：随着低温强度降低及时间延长，水稻空壳率显著增加。水稻品种龙稻5号较东农428更具耐冷性。
Abstract:
In order to reduce the losses of rice production caused by low temperature,the percentage of rice unfilled grains of two cultivars in duding Longdao 5 and Dongnong 428 under potculture in booting stage was compared and the effect of low temparature in booting stage on percentage of unfilled grains was studied.The results showed that with the strength decreasing and prolonged time of low temperature,rate of rice unfilled grains increased significantly.Longdao 5 had more cold resistance than Dongnong 428.
