许多豆科牧草种子的种皮具有一层排列紧密的细胞,水分不易渗入,阻碍了其吸水膨涨萌发。苜蓿的硬实率为10%,草木樨为39%。因此,在播种豆科牧草前,应对硬实种子进行处理。一、硬实处理擦破种皮可以用碾子碾压或用碾压机处理,也可以将豆科牧草种子与一定数量的碎石、沙砾混合后放入搅拌震荡器中进行搅拌震荡,直到种子表面粗糙起毛,但以不压坏种子为度。
Many leguminous herbage seed coat with a layer of closely packed cells, moisture is not easy to infiltrate, hindering the water swelling and germination. The solid ratio of alfalfa was 10% and that of mulberry was 39%. Therefore, hardwood seeds should be processed before legumes are sown. First, the hard handle Rub the seed coat can be used with roller crush or crushed machine processing, can also be a legume forage seed and a certain amount of gravel, gravel mixed into the stirring shaker shaking until the seed surface Rough Rough, but not crushed seeds for the degree.
