1991年,江苏沿江麦区小麦成熟前后遭遇历史少见的连阴雨,不仅造成小麦受溃根衰,成熟提前,更为严重的是影响了小麦适期收获,致使本地小麦普遍发生田间穗发芽现象。在这特定的自然条件下,笔者通过定田定点、取穗剥粒、选择长势平衡、成熟较早的扬麦5号小麦田,按“品”字形定3点(每点田定200穗),于麦子成熟后2天(6月4日)至收获(6月9日),每天下午5时查穗发芽率,同时每点取穗若干、进行室内考
In 1991, before and after the maturity of wheat along the Yangtze River in Jiangsu Province, wheat suffered rare rainy days, which not only caused the wheat to suffer from the collapse of the root tubercle, but also advanced the maturity earlier. More seriously, it affected the wheat harvest and caused the spikelet sprouting in the field. In this particular natural conditions, the author fixed by the fixed field, take the ear stripping grain, select the growing balance, early maturity Yang wheat No. 5, according to “character” shape 3:00 (200 points per Tian Tian Ding) , Wheat germination after 2 days (June 4) to harvest (June 9), at 5 pm every day to check the sprouting rate, while taking a few per ear, for indoor test
