摘要
为验证缓控释肥料对水稻的增产效应,采用田间小区试验方法,对缓控释肥料、晚稻专用配方肥和单质肥料进行了对比研究。结果表明:与晚稻专用配方肥、单质肥料相比,缓控释肥能改善晚稻经济性状,增加产量,提高肥料单位养分的稻谷产出能力,增加施肥收入,但缓控释肥料的成本较高,肥料投入产出比有所降低。
In order to verify the increasing effect of slow releasing fertilizer on rice, the field plot experiment was adopted to conduct comparative study among slow releasing fertilizer, special fertilizer for late rice and single matter fertilizer. The results showed that in comparison with special fertilizer for late rice and single matter fertilizer, the slow releasing fertilizer can improve economic traits of late rice, increase yield, enhance grain producing capacity per unit nutrition of fertilizer, and increase fertilizer income. But slow releasing fertilizer has high cost, the ratio of input to output of fertilizer will be decreased in certain level.
