毛叶苕子是我省优良绿肥之一。由于种子产量低,亩产不过百斤左右,而作为绿肥播种时,每亩播量就需约10斤(收籽用播量每亩3斤),目前毛苕种子远远不够生产上的需要。毛苕种子中还有约25％的“硬籽”,播种后很难吸水发芽;如能提高硬籽的发芽率,就可减少播量,扩大毛苕种植面积,降低成本。为解决这一问题,我们于1973年3月采用理化、生物激素等方法,如以不同浓度的硫酸、硫酸锰、石灰水、920、草木灰水浸种和碾米机作不同程度的碾磨共22项处理,观察对毛苕种子发芽率的影响。考虑到各种处理对硬籽和软籽的影响是不一致的,除碾磨处理外,其余浸种处理都将硬籽和软籽分别进行。
Mochi leaves is one of the fine green manure in our province. Due to the low seed yield, but per kilogram per kilogram or so, and when sown as green manure, sowing per acre will need about 10 pounds (received seeding sowing 3 acres per acre), at present, the seeds are far from enough for production needs . There are about 25% of the “hard seeds” in the seeds of the mulberry seeds, which are hard to absorb water and germinate after sowing. If the germination rate of the hard seeds can be increased, the sowing rate can be reduced, the planting area of the mullet can be enlarged, and the cost can be reduced. In order to solve this problem, we used physical and chemical, biological hormones and other methods in March 1973, such as sulfuric acid, manganese sulfate, lime water, 920, grass and ash mulching and milling machines with different degrees of milling for a total of 22 Item processing, observe the effect on the germination rate of the cathartes seeds. Taking into account the impact of various treatments on hard seeds and soft seeds is inconsistent, except grinding treatment, the rest of the seed soaking hard seeds and soft seeds were carried out separately.
