小麦何时收获好?这个问题颇有讲究。收早了,灌浆不充分,产量低,质量差;收晚了,籽粒中的养分倒流,不仅降低产量和品质,而且易掉穗落粒。那么究竟什么时间收麦为好呢?实践证明,要以小麦成熟的特点来分析确定。小麦成熟可分四个阶段。其外部形态特征分别是:①乳熟阶段——植株下部叶片变黄、茎杆有弹性,基部节间开始皱缩、内颖和籽粒尚呈绿色,内含物为乳汁状,此时籽粒体积已达最大值,但含水量较高,不宜收
When is the wheat harvested? The problem is quite particular. Close early, filling inadequate, low yield, poor quality; received late, the nutrients in the grain backwards, not only reduce the yield and quality, but also easy to spike falling granulation. So what time to receive wheat as well? Practice has proved that the characteristics of wheat to mature analysis to determine. Wheat maturity can be divided into four stages. The external morphological characteristics are: ① Milky stage - the leaves of plants turn yellow, stem elastic, basal internode began to shrink, Ying Ying and the grain is still green, the contents of milk-like, then the grain size Has reached the maximum, but high water content, should not be closed
