我县历年春季雨少,影响旱地棉花适时播种抓全苗。过去曾试行过干子寄种,在棉花播种适期内“到时不等墒”。播后虽然下了点小雨,但种子刚吸水萌动,表土就干了,仍然出不了苗,还会造成烂子和烧芽。1981年春季,我们进行了“干子早播,等雨出苗”试验,获得成功。从1月14日到4月14日分5次播种,结果3月15日和4月4日播种的分别于4月19日和24日出苗,出苗率达97—98%,基本全苗。实践证明,旱地棉花干子
My county over the spring rainy season, affect the timely planting of dry cotton grasp the whole seedlings. In the past, we tried to send dry seeds and sow the seeds in the cotton sowing period. Although after the broadcast under a bit of light rain, but the seeds just water sprout, topsoil to dry, still can not get seedlings, but also cause rotten child and burning buds.

Practice has proved that dry cotton dry seeds
