氮肥施用量对豫东黄潮土区不同肥力土壤大蒜产量的影响
Effects of Nitrogen Fertilizer Application Amount on Garlic Yield in Different Fertility Soil in Yellow Fluvo-aquic Soil Region in Eastern Henan
摘要
Abstract
The effect of nitrogen application amount on garlic yield under different soil fertility levels was studied with Songcheng garlic as material in yellow fluvo-aquic soil region in eastern Henan. The results showed that when the application amount of the phosphorus and potassium fertilizer were suitable,the re-lationship between garlic yield and application amount of nitrogen fertilizer under all the soil fertility levels was fit for quadratic function. The optimal application amounts of fertilizer were phosphorus ( P2 O5 ) of 180. 0 kg/ha,potassium(K2O) of 300. 0 kg/ha,nitrogen(N) of 354. 0 kg/ha for high yield field, phos-phorus(P2O5) of 135. 0 kg/ha,potassium(K2O) of 240. 0 kg/ha,nitrogen(N) of 288. 0 kg/ha for medi-um yield filed,and phosphorus(P2O5) of 90. 0 kg/ha,potassium(K2O) of 180. 0 kg/ha,nitrogen(N) of 264. 0 kg/ha for low yield filed,the corresponding best economic outputs were 22 209. 0 kg/ha,17 041. 5 kg/ha and 12 511. 5 kg/ha,respectively.关键词
