近几年来,各地广大贫下中农和科技人员大力开展合理施肥的科学实验,在我国农民原有的“塞兜”“捻头’、“安兜灰”、“沾秧根”等集中施肥经验的基础上,进一步研究总结出氮肥深层施肥的先进技术。这对用好氮肥,发挥氮肥增产潜力,起了积极作用。一、氮肥深施的增产作用氮肥深层施肥就是将碳铵(碳酸氢铵)、氨水用人工或施肥机
In recent years, the vast majority of poor and middle-ranking peasants and scientific and technological personnel around the country have vigorously carried out scientific experiments on rational fertilization and have concentrated their fertilizing experience in the original “plug pocket”, “twist head”, “An dang gray” and “radiant root” On the basis of further research to sum up the advanced technology of deep fertilization of nitrogen fertilizer.This is good for nitrogenous fertilizer, nitrogen fertilizer production potential to play a positive role.A fertilizer application of deep fertilization of nitrogen fertilizer is the ammonium bicarbonate (ammonium bicarbonate) , Ammonia using artificial or fertilizer machine
