不同土壤类型夏玉米推荐施肥效应研究
Effect of Recommend Fertilization on Summer Maize in Different Soil Groups
摘要
Abstract
In order to increase the efficiency of fertilizer utilization and grain yield of summer maize, Field experiment was carried out to study the effect of Nutrient Expert( NE) and ASI recommend fertilization on the yield, economic benefit of summer maize, and N, P, K utilization efficiency by NE recommend fertilization in yellow-cinnamon soil, cinnamon soil and fluvo-aquic soil of He'nan Province. The results showed that NE and ASI recommend fertilization could get the same yield as farmer accustomed fertilization with less fertilizer in the 3 soil types. Economic efficiency was the best in fluvo-aquic soil. In the base of NE, the yield increased rate of nitrogen, phosphorus and potassium fertilizers was 17.35% , 9.58% and 6.86% , respectively, in yellow-cinnamon soil. It was 21.93% , 12.83% and 8.10%, respectively, in cinnamon soil. It was 8.46%, 8.64% and7.06%, respectively, in fluvo-aquic soil. N, P and K utilization efficiency was31.38% -40.84% , 20. 15% -24.47% and 45.58% -49.95% , respectively. The agronomic efficiency was 5. 23 - 10. 26 kg/kg, 12. 99 ~ 16. 52 kg/kg and 9. 57 - 11. 83 kg/kg, respectively. Fertilizer utilization efficiency was higher in yellow-cinnamon soil, but was lower in fluvo-aquic soil. ASI recommend fertilization could increase the yield and economic benefit obviously in Yellow-cinnamon soil. NE recommend fertilization could improve the yield and economic benefit significantly in fluvo-aquic soil.关键词
