(1)重施底肥底肥不仅可以源源不断地供给水稻各个生育阶段对养分的需要,而且可以改良土壤,提高肥力。为使底肥持久,一般底肥用量应占总施肥量的50—80%,并且都在插秧之前施下。底肥要坚持以有机肥为主,以化肥为辅。如土壤保肥力强,基肥用量较多时,可采用全层施肥法,即结合多次犁耙施肥,达到层层有肥,以利根系吸收利用;土壤保肥力不强,施肥用
(1) heavy base fertilizer not only can supply a steady stream of paddy at all stages of the growing needs of nutrients, but also can improve the soil and improve fertility. In order to make the base fertilizer durable, the general amount of base fertilizer should account for 50-80% of the total amount of fertilizer, and all are applied before transplanting. Base fertilizer to adhere to the main organic fertilizer, supplemented by chemical fertilizers. Such as soil fertility and strong, more basal fertilizer, the full-thickness fertilization method can be used, that is combined with multiple rake fertilization, to achieve a layer of fertilizer to facilitate the absorption and utilization of roots; soil fertility is not strong, fertilization
