水稻协调施肥是运用土壤测试手段,根据土壤养分状况、水稻需肥规律和产量指标及应用多年、多点化肥试验资料,参照国内外测土施肥经验而进行的科学施肥技术。这种施肥技术,采取有机肥与化肥相配合的肥料结构,以氮定磷增钾,协调土壤养分平衡,达到提高产量、提高化肥利用率、提高经济效益、培肥地力的目的。 一、施肥效果 1984年开始在全省42个单位共51个点次,进行了水稻协调施肥小区试验及80万亩大面积示范,收到了显著效果。1985年又继续进行百万亩大面积示范,深受群众欢迎。
Rice fertilization is the use of soil fertility testing methods, based on soil nutrient status, fertilizer demand and yield indicators of rice and the application of multi-year and multi-point fertilizer test data, with reference to the experience of soil testing and fertilization at home and abroad conducted scientific fertilization technology. This fertilization technology, to take organic fertilizer and fertilizer to match the fertilizer structure, nitrogen and phosphorus by potassium, coordination of soil nutrient balance, to improve yield, increase fertilizer utilization, increase economic efficiency, fertility and fertility purposes. First, the effect of fertilizer In 1984, 42 units in the province a total of 51 points, conducted a pilot rice fertilization plot experiments and 800000 acres of large-scale demonstration, has received significant results. In 1985, it continued to carry out a large-scale demonstration of millions of mu and was well received by the masses.
