摘要
通过对涝渍改良稻田上主要优化种植模式的投入、产出及对土壤有效养分影响的研究 ,从经济效益和生态效益两方面对主要优化种植模式进行了比较 ,结果表明“油 -瓜 -稻”的产投比较高 ,“菜 -椒 /棉”的生态效益较好 ,发展潜力较大 ,“麦 /瓜 /棉”的经济效益和生态效益都不理想。
Through the compare with input?output and soil nutrient of different excellent planting models on improved flooded rice field,the results was found that the ratio of output and input of 'rape watermelon rice' was higher than other models,the ecological benefit of 'vegetable chilli/cotton' was better than others,but both ecological benefit and economic benefit of the 'wheat watermelon cotton' were not good
