近年来,我们发现一些果农因不懂得果树施肥与果树生长的密切关系,为加快树体发育,促进早发,提早结果,对幼龄果树育目大量施用氮素化肥,常常导致果树发生氨中毒,从而影响果树正常生长甚至死亡。 In recent years, we found that because some farmers are not aware of the close relationship between fruit tree fertilization and fruit tree growth, in order to speed up the development of tree body, promote early onset and early result, applying nitrogenous fertilizer to young fruit tree is often caused ammonia poisoning , Thus affecting the normal growth of fruit trees and even death.
