1选用高效品种实践证明,实现超高产栽培在品种利用上应选用优良高水肥的品种,若配合良好的栽培方法,均提高产量。2增磷补钾,平衡施肥高效栽培肥料运筹总的要求是:在原有地力和施肥基础上,通过稳氮、增磷、补钾,调节氮、磷、钾的平衡关系,充分发挥不同营养元素的整体效益。在产量4500~5250kg/hm2的地力基础上,施优质农家肥4.5万~6.0万
1 Selection of highly efficient varieties proved that the implementation of ultra-high yielding varieties should be used in the selection of good high water and fertilizer varieties, with good cultivation methods, are to increase production. 2, increasing potassium, balanced fertilization and efficient cultivation of fertilizer The overall requirements are: on the basis of the original fertility and fertilization, through nitrogen, phosphorus, potassium, regulating the balance of nitrogen, phosphorus and potassium, give full play to different nutrients The overall effectiveness. In the yield of 4500 ~ 5250kg / hm2 on the basis of fertility, the application of high-quality peasant 45,000 ~ 60,000
