摘要
以潮土为供试土壤,以金乡县白皮大蒜为供试品种,以尿素、过磷酸钙、硫酸钾为供试肥料,采用"3414"肥料试验,建立了大蒜施肥模型。在试验条件下,氮磷钾最佳经济施用量为纯N 29.5 kg/667 m2、P2O515.2 kg/667 m2,K2O 22.7 kg/667 m2。
The garlic fertilization model was established using fertilizer＆quot;3414＆quot;test,using moisture soil as the experimental soil,with white garlic of Jinxiang County as tested varieties,with urea,superphosphate,potassium sulfate as tested fertilizer. In the experimental conditions,the optimum economic fertilization amount of nitrogen,phosphorus and potassium was pure N 29.5 kg/667 m2,P2O5 15.2 kg/667 m2,K2O 22.7 kg/667 m2.
