不同施肥模式对典型粮菜轮作作物产量及经济效益的影响
Effects of Different Fertilization Modes on Yield and Economic Benefit of Typical Food Crop and Vegetable Rotation System
摘要
Abstract
Field plot experiment was carried out to study the effects of different fertilization modes on the yield and economic benefit of crops in potato-spring maize-Chinese cabbage rotation system. The results showed that the optimized fertilization mode OPT3(transferring the whole phosphorus and potassium fertilizer for spring maize to the production of potato)could not only save labor and fertilizer,but also acquire the highest yield and economic benefit. In comparison with the farmer's fertilization method, the optimized fertilization mode OPT3 enhanced potato yield by 6.15%,slightly decreased spring maize yield (P>0.05),in-creased Chinese cabbage yield by 6.85%,and improved the annual economic benefit by 9759.42 yuan/hm2. So transferring the whole phosphorus and potassium fertilizer for spring maize to potato production was the optimal fertilization method for potato-spring maize-Chinese cabbage rotation system.关键词
