谷子粒小,又是间苗作物,一般留苗数仅为播量的20％,生产上间苗用工量大,常因劳力紧张影响适时间苗管理。为了利于精量播种,节省间苗用工和今后实行机械化播种,我们进行了种子包衣试验。种子包衣的材料采用纤维素、化肥和肥土等,将经过清选的种子喷湿后,连同包衣材料,放入包衣机内,经机械滚动制成包衣种子。包衣后籽粒直径约3.5毫米左右,比不包衣的增加3/4,一千颗粒重25克上下,
Millet grains small, but also thinning crops, the general number of seedlings only for the amount of sowing 20% of production Miao Miao large amount of work, often due to labor stress affect timely Miao management. In order to facilitate the precision sowing, save the Miao Miao employment and the implementation of mechanized planting in the future, we conducted a seed coating test. Seed coating materials using cellulose, fertilizers and soil, etc., will be cleared after the seed spray wet, together with the coating material, into the coating machine, made of coated seeds by rolling machinery. After coating the grain diameter of about 3.5 millimeters than the non-coating increased by 3/4, a thousand grains weight 25 grams up and down,
