在种麦前,做一下麦种发芽率试验,就能鉴别出是能用的麦种,还是不能用的麦种。正面介绍几种测定麦种发芽率的方法: 1 砖块测定法。取麦种两份,每份100粒。找两块吸湿性强的砖块,吸足水分。选一处30cm~2、土壤疏松、地下害虫少的地段,松土整平浇透水。先用砖块在整平的土壤中划出面积,将两份麦种分别撒在两块砖大小的面积内,再压上砖块,在砖块上浇透水,以后每大向砖块浇

In the wheat before, make a germination test of wheat germination rate, you can identify the usable wheat species, or wheat can not be used. Positive introduction of several methods to determine the germination rate of wheat: a brick assay. Take two wheat seeds, each 100. Find two pieces of hygroscopic brick, absorb enough water. Select a 30cm ~ 2, loose soil, less underground pests, soil leveling watering. First with the bricks in the leveling of the soil to draw the area, the two wheat were sprinkled in two brick size of the area, and then pressed on the brick, drenched in the brick water, after every big to the brick pouring
