摘  要:
通过设置6个施肥水平处理,对蒜薹、蒜头产量进行显著差异性方差分析的方法,研究了高寒地区在稳施氮肥900 kg/hm2基础下,配施不同比例的磷钾肥,对大蒜蒜薹、蒜头产量的影响。结果显示,当过磷酸钙施用量控制在300~450 kg/hm2,氯化钾施用量控制在300~450 kg/hm2,蒜薹产量增幅在80.2%~99.7%,蒜头产量增幅在28.5%~40.3%,产投比在10.7%~13.3%。研究表明,氮磷钾配合按照合适比例施用,才能使大蒜有最佳增产、增收的效果。

摘  要:
In the field test with 6 fertilization treatments,based on application of N fertilizer at 900/hm2,the effects of applying different combinations of P and K fertilizers on the yield of garlic bolt and garlic were studied by significant variance analysis on the yield of garlic bolts and garlic.It was found that when the fertilization rates of Ca3(PO4)2 and KCl were in 300~450 kg/hm2 and 300~450 kg/hm2,resp.,the yield of garlic bolts and garlic increased by 80.2 %~99.7 % and 28.5 %~40.3 %,resp.,with the ratio of input and output being 10.7 %~13.3 %.
