大家都知道豆科覆盖作物的价值,但是许多植胶者认为,建立豆科覆盖作物的成本太高,是得不偿失的。更有效和更便宜地建立豆科覆盖,将会降低成本和增加效益。一、种子发芽大多数的豆科作物都是用种子繁殖的,由于不能预测种子中究竟有多少“硬粒种子”,所以种子的发芽率差异极大。所谓“硬粒种子”,就是不透气种皮吸收水份的天然通道被阻塞而致不能吸收水份的种子。已经发明了几种改进种子发芽的方法。
Everyone knows the value of leguminous crops, but many sellers believe that the cost of establishing leguminous crops is too high to justify. Building legume coverage more efficiently and cheaper will reduce costs and increase efficiency. First, the seed germination Most leguminous crops are used seed breeding, because they can not predict exactly how many seeds “hard seed”, so the seed germination rate varies greatly. The so-called “hard seed” is the impermeable seed coat to absorb moisture in the natural channel is blocked and can not absorb water seeds. Several methods have been invented to improve seed germination.
