尿素供应不足,一直是困扰再生稻生产面积扩大,产量提高的重要原因之一。针对这个问题,我们从1988年开始对氯化铵用作再生稻促芽肥和发苗肥进行了试验研究, 1989年继续试验和示范,近两年推广面积较大。氯化接作促芽肥和发苗肥有如下优点:一是缓解了尿素日趋紧张的矛盾,为发展再?
Lack of urea supply has been one of the important reasons that plagued the expansion of production area of ratooning rice and the increase of output. In response to this problem, we started from 1988 on the use of ammonium chloride as a regenerative rice bud and hair fertilizer experiment conducted in 1989 to continue testing and demonstration, the past two years to promote a larger area.
