测土配方施肥是根据作物需肥规律、土壤供肥特性与肥料效应,在以有机肥为基础的条件下,提出氮、磷、钾和微肥的适宜用量和比例及其相应的施肥技术。在我市水稻主要产区龙凤镇开展水稻“3414”肥效试验,获得水稻产量三元二次和一元二次肥料效应方程。并获得最佳施肥方案为:纯N13.78-14.64kg/亩,P2O53.5-6.64kg/亩,K2O 5.4-5.96kg/亩。
Soil testing and formula fertilization is based on the rule of crop fertilizer demand, soil fertility characteristics and fertilizer effect. Based on the organic fertilizer, the appropriate amount and proportion of nitrogen, phosphorus, potassium and trace fertilizers and their corresponding fertilization techniques are put forward. The rice “3414” fertilizer effect experiment was carried out in Longfeng Town, a major rice producing area in our city, to obtain the quadratic quadratic and one yuan secondary fertilizer effect equations for rice yield. And get the best fertilization program: pure N13.78-14.64kg / mu, P2O53.5-6.64kg / mu, K2O 5.4-5.96kg / mu.
