北京市通州区开展小麦施用缓控释肥试验,对比不同肥料产品对小麦的作用。结果表明,施“含腐植酸”缓控释肥,可促进小麦生长,改善小麦的经济性状;处理产量明显高于底施等养分的单质肥料,增产31.7 kg/667 m2,增产率8.6%,增产效果明显,产量差异达显著水平;经济效益方面,施用“含腐植酸”缓控释肥与底施等养分单质肥比,667 m2增加纯效益14.91元。
Tongzhou District, Beijing launched a controlled release fertilizer test of wheat to compare the role of different fertilizer products on wheat. The results showed that the controlled release fertilizer with humic acid could promote the growth of wheat and improve the economic traits of wheat. The yield of treatment was obviously higher than that of single nutrient such as basal application, which increased yield by 31.7 kg / 667 m2 and yield by 8.6 %, Yield increase effect is obvious, the yield difference reached significant level; economic benefits, the application of “humic acid ” controlled release fertilizer and bottom dressing and other nutrient elemental fertilizer ratio, 667 m2 increased net benefit of 14.91 yuan.
