| 摘 要： | 利用2009年6-8月逐日、逐时平均气温,根据日冷积温与水稻空壳率的关系以及敏感期内水稻敏感群体数量分布概率,评估水稻发生障碍型冷害而导致的空壳率及减产率.结果表明:2009年黑龙江省水稻种植区均发生了不同程度的障碍型冷害,总空壳率在10%以上,三江平原水稻减产程度重于松嫩平原,这与实际情况基本吻合.该方法足在明确水稻...

| Abstract: | A phased low temperature occurred in the summer of 2009 in Heilongjiang Province,resulting in a sterile-type rice cool injury,during which the field crops had varying degrees of delayed-type cool injury and fertility postponement.Through calculating the daily cool accumulated temperature according to its relationship with the rice emptygrain rate and the probability distribution of the number of sensitive rice groups during sensitive periods,the rice emptygrain rates and loss rates caused by the sterile-typ... |
