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.
