尿素供应不足一直是影响再生稻面积扩大、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和示范推广。氯化铵作促芽肥和发苗肥有如下优点:一是缓解了尿素供应日趋紧张的矛盾,为发展再生稻开辟了新肥源。二是节省投资,按农民购买国家供应再生稻专用尿素,每千克综合价0.89元,每亩用15～17.5千克计,施用等量纯氮的
The lack of urea supply has been one of the important reasons that affect the area of ratoon rice and the yield increase. In response to this problem, we started from 1988 on the use of ammonium chloride as a ratoon rice bud and fertilizer development and experiment carried out demonstration. Ammonium chloride as a budding fertilizer and hair Miaofei has the following advantages: First, to ease the contradiction between the increasingly tight supply of urea, opened up new fertilizers for the development of ratooning rice. The second is to save investment, according to farmers to buy special urea for regenerative rice, the integrated price of 0.89 yuan per kilogram, with 15 ~ 17.5 kg per acre plan, the same amount of pure nitrogen
