摘要: 为了验证水稻专用配方肥的施用效果,寻找出宁夏自流灌区水稻的最佳施肥量和施肥比例,进行了水稻大田示范和田间对比试验。结果表明:基施腐殖酸配方肥(20-6-9)46.3kg/667m^2,分别在水稻的分蘖期和抽穗期追施尿素10kg/667m^2、6kg/667m^2,既可满足作物生长对氮、磷、钾养分的需求,又可达到节本增效的目的。
Abstract: In order to test rice special formula fertilizer for rice to find the best fertilizing amount and proportion Ningxia gravity irrigation area, the rice field demonstration and field tests were carried on. The results showed that: the base fertilizer humic acid fertilizers (20-6-9) at 46.3kg/667m2, Topdressing Urea lOkg/667m2, 6kg/667m2 was fertilized respectively in the tillering stage and heading stage of rice, which not only meet the crop growth on nitrogen, phosphorus, potassium nutrient demand, but also reduce cost and increase benefit.
