一、施肥原则1、基肥冬前施。春麦地的基肥，不论有机肥还是无机肥，均应冬前早施。春季因时间紧，施肥会影响早播，且易跑墒，影响出苗。2、化肥深施。化肥做基肥应结合秋翻深施。冬天温度低，可防止氮的损失，且保证苗期及早吸收，磷肥除留小部分做种肥外，其余应全部做基肥 First, the principle of fertilization 1, basal fertilizer applied before winter. Spring wheat base fertilizer, whether organic or inorganic fertilizer, should be applied as early as winter. Spring time due to tight, fertilization will affect early sowing, and easy to run moisture, affecting emergence. 2, deep fertilizer. Fertilizer base fertilizer should be combined with autumn turn deep facilities. Winter temperature is low, to prevent the loss of nitrogen, and to ensure early absorption of seedling stage, except for a small part of phosphorus fertilizer to do, the rest should be done all the basic fertilizer
