用高分子树脂包膜尿素、改性长效碳铵及普通尿素中加入尿酶抑制剂的氮肥(长效氮肥)与钙镁磷肥、氯化钾混配一次基施,结果表明,施用长效氮肥比普通氮肥增产5.36%~8.33%,植株后期各部位的养分含量水平比普通尿素处理的高,化肥吸收率亦提高1.71%~4.04%。
With the polymer resin coated urea, modified long-acting ammonium bicarbonate and ordinary urea added urease inhibitor of nitrogen (long-acting nitrogen) and calcium magnesium phosphate, potassium chloride mixed with a base application, the results show that the application of long-acting Nitrogen fertilizer increased 5.36% ~ 8.33% more than common nitrogen fertilizer, and the nutrient content of various parts of the plant was higher than that of ordinary urea in later stage, and the absorption rate of chemical fertilizer also increased by 1.71% ~ 4.04%.
