花生配方施肥是根据花生的需肥规律,土壤的供肥能力和肥料效应,在增施有机肥的基础上,按照氮、磷、钾和微量元素的适当用量进行科学配比,合理施用,以满足花生生长发育对各种营养元素的需要,实现高产优质。配方施肥能有效地提高产量和效益,提高化肥利用率和提高土壤肥力。一、花生需肥规律据山东花生研究所研究测定:在亩产250～350公斤荚果时,每生产100公斤花生荚果所需要吸收的氮、磷、钾素
Peanut formula fertilization is based on the need of peanut fertilizer law, soil fertility and fertilizer effect, based on the addition of organic fertilizer, according to the appropriate amount of nitrogen, phosphorus, potassium and trace elements in scientific matching, rational use of Peanut growth and development to meet the needs of a variety of nutrients to achieve high yield and quality. Formulation fertilization can effectively improve yield and benefit, increase fertilizer utilization and increase soil fertility. First, the law of peanut fertilizer According to the Shandong Institute of Peanut Research determined that: in the yield of 250 to 350 kg per pod, each produced 100 kg of peanut pod need to absorb nitrogen, phosphorus and potassium
