稻田冬种复种模式的综合效益研究
A Study on the Comprehensive Benefits of Multiple Winter-cropping Patterns of Paddy Field
摘要
Abstract
The benefit of paddy field cropping system includes the economic benefit,the ecological benefit and the social benefit,and the correct evaluation of it is not only in theory,but also in production practice.By using AHP method and comprehensive index method the index system of evaluation factors was established, and the ecological and economic benefits of different multiple winter-cropping patterns were studied.The re-sults showed,the comprehensive benefit index of 2012 winter cropping pattern was in the order:Treatment C ( rape/peanut-rice )>Treatment E ( vegetable/peanut‖corn-rice )>Treatment B ( green manure-rice-rice )>Treatment D( potato/corn‖soybean-rice)>Treatment A( fallow-rice-rice) ,while in 2013,Treatment D( vege-table/peanut‖corn-rice)>treatment B( rape/peanut-rice)>treatment E( green manure crops-rice-rice)>treat-ment C( potato/corn‖soybean-rice)>treatment A( fallow-rice-rice) ombining the two-year results,the compre-hensive benefits of“rape/peanut-rice”and“vegetable/peanut‖corn-rice”models were relatively good.But the “vegetable/peanut‖corn-rice”model although had good economic benefit,due to its need for more labor and fertile soil,it is suitable for the areas of the fertile soil and abundant labor.In the“rape/peanut-rice”model, rape straw contains nitrogen,phosphorus,potassium and other ingredients,returning straw to the soil is condu-cive to the improvement of soil and farmland system,to the increase of crop yield;growing peanuts instead of growing early rice,thanks to its price advantage over rice,can increase the income of the farmers;after peanut harvesting,growing rice ensures the food needs.This model takes the economic benefits,environmental benefits and social benefits into account,hence worth extension.But peanut varieties should be early maturing so as to ensure the growth period of late rice.关键词
