合理施用磷肥,可增加作物产量,改善产品品质。如在谷类作物中,可加速作物分蘖,促进幼穗分化、灌浆和籽粒饱满,促使早熟;在瓜类、茄果类蔬菜及果树等作物中,可促进花芽分化和开花结实,提高结果率;在栽种豆科绿肥时,可提高绿肥鲜草产量,使根瘤菌固氮量增多,达到“以磷增氮”的目的;此外,还可增加浆果、甜菜、甘蔗以及西瓜等的糖分、薯类作物薯块中的淀粉含量、油料作物籽粒含油量。然而,磷肥并非施用越多越好,因为当年施入的磷肥不能完全被作物吸收,会在土壤中累积,过量施用磷肥不
Rational application of phosphate fertilizer can increase crop yield and improve product quality. For example, in cereal crops, crop tillers can be accelerated to promote young ear differentiation, grain filling and full grain, which can promote early maturity. In fruits such as melon, eggplant and fruit tree, flower bud differentiation and flowering can be promoted and the result rate can be increased; In the cultivation of leguminous green manure, can increase the yield of fresh green manure, rhizobium nitrogen fixation increased to achieve the purpose of “increasing phosphorus by nitrogen”; In addition, you can increase the sugar, potato, sugar beet, sugar cane and watermelon, potato Crops potato starch content, oil crop grain oil content. However, phosphate fertilizer is not applied as much as possible, because the phosphate fertilizer applied in that year can not be fully absorbed by the crop and will accumulate in the soil. Over-application of phosphate fertilizer does not
