洱海北部地区环境友好型种植模式筛选
Screening of Environment-friendly Cropping Mode in the Northern Region of Erhai Lake
摘要
Abstract
[Objective] Screening of intercropping patterns suitable for local planting was studied from the standpoint of economic benefit and environmental benefit. [Method] A field plot experiment was carried out on Luoshijiang edge of the northern region of Erhai Lake where Zhaoyi village of Shangguan town is situated; Nutrient balance, economic benefits, crop quality and soil nutrient residue status of intercropping patterns were analyzed after samples were tested in the laboratory. The four factors influencing economic and environmental benefits were identified as the index set in the intercropping by using methods of subjective weight and objective weight, and these factors are revenue, quilty of commodity, inorganic nitrogen in soil and rapidly available phosphorus in soil. Different intercropping patterns were evaluated by using fuzzy comprehensive evaluation method. [ Result] The results showed that the score of Viciafava and garlic intercropping mode with area of vicia fava and garlic ratio of 1 : 3 was the highest in the 14 intercropping modes, and it was an environment-friendly cultivation mode because both economic and environmental benefits were higher than other modes. Followed by the onion and garlic intercropping mode with area of onion and garlic ratio of 1 : 3, and its score was 0.624, its economic benefits was better than others, but the environmental effect slightly worse than others. Ryegrass and garlic intercropping mode with area of ryegrass and garlic ratio of 1 : 3, and it was ranked the third for the score was 0.609, optimum environmental benefits, but the input was lower. The lowest score of the rape and garlic intercropping mode with area of rape and garlic ratio of 1 : 1, and its score was 0.084, its economic and environmental benefits was lower because of the large differences in plant height. [Conclusion] In this study, the appropriate local environment-friendly planting mode was Vicia fava and garlic ratio of 1 : 3.关键词
