安徽省岳西县1988年在34700亩的水旱田上进行了配方施肥的示范推广,其中茶园6200亩,增产茶叶1.5万多公斤:玉米500亩,水稻28000亩,增产粮食125万公斤。共增值80多万元,扣除成本25万元,实际创益55万多元,取得了明显的经济效益。为了探讨配方施肥的科学性、该县土肥站在各区建立了试验点。通过试验表明,结合各地土壤的氮、磷、钾有效含量进行氮、磷、钾肥的配合使用,能使水稻、玉米增产8～26.1％,平均增产10％以上。在
In 1988, Yuexi County, Anhui Province conducted a demonstration and promotion of formula fertilization on 34,800 hectares of dry and upright farmland, of which 6,200 hectares of tea plantations produced more than 15,000 kilograms of tea: 500 acres of corn, 28,000 acres of rice and 1.25 million kilograms of grain. A total value of more than 800000 yuan, deduct the cost of 250000 yuan, the actual profit more than 550000 yuan, has made obvious economic benefits. In order to explore the scientific nature of the formula fertilizer, soil and fertilizer stations in the county set up a test point in various districts. The experiment shows that with the effective content of nitrogen, phosphorus and potassium in the soil, the combined use of N, P and K fertilizers can increase the yield of rice and corn by 8-26.1% and increase the yield by more than 10% on average. in
