生物有机肥对大蒜生长发育及产量的影响

摘要

为了筛选适合贵阳市大蒜栽培施用的生物有机肥,为其高产优质栽培提供参考,以绿康壮叶面肥、惠美丰腐殖酸、有机肥和高效生物肥为材料,采用田间试验研究生物有机肥不同施用组合对毕节紫皮大蒜生长发育及产量的影响.结果表明,4种生物有机肥对大蒜气生鳞茎做种和蒜头做种的植株的生长发育和产量均有不同的促进作用,并以绿康壮叶面肥和惠美丰腐殖酸混合施用的效果最佳,产品的营养指标较好.%In order to select the bio-organic fertilizer suitable for the cultivation of garlic and provide the referential guidance for the cultivation of high yield and good quality of garlic in Guiyang,the authors used Lvkangzhuang foliar fertilizer,Huimeifeng humic acid,organic fertilizer and efficient biological fertilizer and different combinations of these four types of bio-organic fertilizers to study their effects on the developmental growth and yield of Bijie purple skin garlic.The results showed that the fertilization system using four new fertilizers promoted the vegetative growth of garlic seedlings when using aerial bulbs and bulbils as seeds.Among those,the combinative application of Lvkangzhuang green foliar fertilization with Huimeifeng humic acid showed the most significant promotive effect on the growth and resulted in the better nutrient index.
