小麦种子发芽率的高低,决定着播后基本苗的多少。正确测定小麦种子发芽率的高低,对小麦的增产或减收起着关键性的作用。现根据本人的实践经验向大家介绍一种十分简便而又快捷的测算方法。将所测小麦种子抽样后称取100克(2两)左右后置于水中浸泡24—36小时,然后在室外选择一块无阳光直射的地方,上面置2—3厘米厚的河沙土(河沙土有返潮特性,俗称“夜潮土”),用砖块将沙土面轻轻拍平后,将小麦种子均匀摊放于沙土表面,再将砖块吸足水份后置于种子上即可。以后每天早晚在砖块上面各浇一次水,一般4—5天即可将种
The germination rate of wheat seeds determines the number of basic seedlings after sowing. Correct determination of the level of wheat germination rate, the increase or decrease of wheat plays a key role. Now based on my own experience to introduce a very simple and quick calculation method. Weigh the measured wheat seeds after weighed 100 grams (about two two) and then placed in water for 24-36 hours, and then in the outdoor choose a place without direct sunlight, placed 2-3 cm thick river sand (river sand There is damp characteristics, commonly known as “night-tide soil”), with a brick sand surface gently pat, the wheat seeds evenly spread on the surface of the sand, and then bricks absorb enough water can be placed on the seeds. After each day sooner or later in the brick above each pouring water, usually 4-5 days to species
