科学合理施肥是玉米获得高产,提升玉米质量,降低生产成本的重要措施之一。合理施肥就是在一定的气候和土壤条件下,为栽培某种作物所采取的有效施肥措施。合理施肥的关键是要最大限度地满足作物对养分的需求,尽量减少养分的损失,以此提高肥料的利用率,使其提高产量和效益。一、提高肥料利用率肥料利用率指的就是当季作物吸收利用的养分数量占所施肥料中该养分总量的百分比。目前,氮肥的利用率仅有50%上下,磷肥的利用率更是低于20%,因而,有效提高肥
Scientific and reasonable fertilization is one of the important measures to obtain high yield of corn, improve the quality of corn and reduce the production cost. Rational fertilization is the effective fertilization measures taken to cultivate a certain crop under certain climatic and soil conditions. The key to rational fertilization is to maximize the crop’s nutrient requirements and minimize the loss of nutrients so as to increase the utilization of fertilizers and increase the yield and profitability. First, to improve fertilizer utilization Fertilizer utilization refers to the amount of nutrients absorbed by the crop during the season as a percentage of the total amount of nutrients in the fertilizer. At present, the utilization rate of nitrogen fertilizer is only about 50%, and the utilization rate of phosphate fertilizer is even lower than 20%. Therefore,
