花生产量的高低与施肥有着密切的关系,尤其是肥力较低的地块,科学施肥具有明显的增产效果。1花生需肥特点花生对氮、磷、钾三要素的吸收量是两头少,中间多即在花生全生育过程中,对氮、磷、钾的吸收是:幼苗期、饱果期、成熟期少,开花下针期、结荚期多。花生吸收的氮素主要来自根瘤固氮据试验测定,花生吸收
The level of peanut production and fertilization are closely related, especially low fertility plots, scientific fertilization has obvious yield-increasing effect. 1 peanut fertilizer characteristics Peanut nitrogen, phosphorus and potassium absorption of three elements is two less, the middle of that in the peanut throughout the reproductive process, the absorption of nitrogen, phosphorus and potassium are: seedling stage, full fruit, mature Less flowering needle, pod stage. Peanut absorption of nitrogen mainly from the nodule nitrogen fixation test, peanut absorption
