推荐施肥对超高产夏玉米产量及经济效益的影响
Effects of Recommended Fertilization on Growth, Development,Yield and Economic Benefit of Superhigh -yielding Summer Maize
摘要
Abstract
Field experiment was conducted to study the effects of ASI recommended fertilization (ARF), superhigh -yielding experienced fertilization (SHF) and peasants' customary fertilization (PCF) on the leaf area index, biomass, plant nutrient accumulation, yield and economic benefit of superhigh - yielding summer maize. The results showed that fertilization could obviously increase maize yield by 9.50% - 18.84%. The maize yields in treatments ARF and SHF were not obviously different, but they were increased respectively by 6.62% and 8.53% in comparison with that in treatment PCF. The combined application of N, P and K fertilizer could significantly increase the leaf area index and biomass of summer maize, and promote the accumulation of N, P and K nutrient in the plants. ARF obtained the best net income and ration of output to input, and it had preferable yield - increasing and income - increasing effects on superhigh - yielding summer maize.关键词
