冬季豆科绿肥苕了、红花草等的生长发育有三大特性:前期生长慢,后期生长快;喜温湿,忌涝渍;对磷肥敏感根据实践经验,要使冬种绿肥获得鲜苗2000千克左右的高产,必须做到“五早一防”。 1.早查苗补播 通过田间检查,凡出苗达不到60％的,都应进行补播。补播方法:每667平方米用0.50～0.75千克种子,浸种露白后 Winter legume green manure, the growth of red flowers and other three major characteristics: early growth slow, rapid growth late; hi temperature and humidity, avoid waterlogging; sensitive to phosphate fertilizer based on practical experience, to make winter seedlings of green manure to obtain 2000 kg About the high yield, must be “five early one defense.” 1. Early check seedlings make up through field inspection, where the emergence of less than 60%, should be supplemented. Replenishment method: 0.67 ~ 0.50 ~ 0.75 kg seed per 667 square meters, after soaking in dew white
