摘要
大田播种不易管理，往往因种子还未发芽，苗田就长满杂草并与种子争水、争阳光，造成种子不易发芽，种子甚至发霉、变质、腐烂。而采取砂床播种，便于管理，发芽率高，出土整齐。
for field seeding,since the bed is inconvient to be managed,a situation-weedgrows fully in the field before germination,which will furtherly cause weed's competition of water,sunlight with the seedling after germinating;they will cause the seeds thathave been sowed into the soil not to germinate easily,and impel the seeds to be molded,deteriorated, rotten progressively. On the contray,sowing the seeds of sand bed is easyto be controlled and produces a high-germination percent and uniform emergence.
