復合肥是撒在土壤表面的,由于復合肥濃度一般都較高,需要避免肥料與種子直接接觸,以免影響出苗或出現燒苗、爛根等肥害現象,所以用撒施的方式最佳。復合肥如果長期使用,會導致土壤板結,還會讓土壤中的含氮量變高,因此在施肥時,最好是以有機肥為主,復合肥為輔,這樣才更有利于植物生長。

  復合肥的介紹

  復合肥料是指含有兩種或兩種以上營養元素的化肥,具有養分含量高、副成分少且物理性狀好等優點,對于平衡施肥,提高肥料利用率,促進作物的高產穩產有著十分重要的作用。

  復合肥生產多使用測土配方測出土壤的養分情況,根據作物需肥規律、土壤供肥性能和肥料效應,在合理施用有機肥料的基礎上,提出氮、磷、鉀及中、微量元素等肥料的施用數量、施肥時期和施用***。

  復合肥肥效長,宜做基肥,但其分解較慢,應根據不同作物地需肥規律在追肥時及時補充速效氮肥,以滿足作物營養需要。
