、省力

2.有(you)的(de)肥(fei)料(liao)或(huo)藥(yao)液(ye)不(bu)宜(yi)采(cai)用(yong)該(gai)方(fang)法(fa)。采(cai)用(yong)掛(gua)吊(diao)瓶(ping)補(bu)肥(fei)應(ying)根(gen)據(ju)具(ju)體(ti)情(qing)況(kuang)而(er)定(ding)。若(ruo)果(guo)樹(shu)發(fa)生(sheng)某(mou)種(zhong)缺(que)素(su)症(zheng)狀(zhuang)

，土施或葉麵噴施效果不理想，而采用掛吊瓶補肥，一般表現見效快

、肥效長。另外，果樹因根係發生腐爛病時，適於采用掛吊瓶補肥法施肥。

3.易造成局部藥害。由於鑽孔的局限性，進入樹體的養分和藥液難以平衡，局部濃度過高會對樹體產生傷害，如嫩葉、花瓣邊緣焦枯，枝條生長受阻，甚至枝組局部枯死等
，因此，正常生長的果樹沒有必要采用掛吊瓶的方法。
