针对玉米果穗含水量过高是种子发芽率降低的主导因素,应千方百计采取各种有效措施,加以预防。 1 站杆剥皮 迅速脱水 果穗站杆剥皮的最佳时机是腊熟时期。一般在收获前7～10天剥开果穗苞叶。裸露雌穗籽粒,利用田间优越的光照和通风条件,促进果穗迅速脱水,加快籽粒后熟饱满。 2 合理贮藏 适时脱粒 果穗收获进入场院后,首先利用场地进行摊晒,再装垛贮藏。针对冬季气温低主要利用通风来降水的特点,场地应选择在远离围墙的地方,以南
Aiming at the maize ear water content is too high is the leading factor of reducing the seed germination rate, should take every possible means to take various effective measures to be prevented. 1 station pole stripping rapid dehydration spike station pole stripping the best time is ripening period. Usually 7 to 10 days before harvest peel the ear bracts leaves. Exposed spike grain, the use of field superior light and ventilation conditions, to promote the rapid dehydration of the ear, speed up the ripe grain full. 2 reasonable storage timely threshing Ear harvest into the yard, the first use of the site to spread the sun, then pack storage. In view of the low temperature in winter, the main use of ventilation to precipitation characteristics, the site should be chosen away from the wall of the place, south
