Analyze And Dissemination Research On Rice-wheat Cropping System

The reasonable farming system is the foundation of realizing eco-agriculture's positive cycle andthe rural economics' sustainable development. This article is based on the survey ofGreenhouse-Ginger-Later rice (Paddy-upland) rotation pattern's expansion and current situation atNanhu District of Jiaxing City, With the combination of analysis from aspects of economic, ecologicaland social benefits, and also problems existed in the expansion of this pattern, and then offer somesuggestions. Which the suggestions have definitely reference value to the expansion of paddy-uplandrotation pattern as well as others new technology of Food-Economy Combination, and also havesuggestions of developing new farming mode and sustainable eco-agriculture.This article has been make analysis of the Greenhouse-Ginger-Later rice (Paddy-upland) rotationpattern from the economy, social and eco-environmental benefits comprehensively; the results show thatthe Greenhouse-Ginger-Later rice (Paddy-upland) rotation pattern's expansion has gained majoreconomy, social and eco-environmental benefits. The pattern of Greenhouse-Ginger have gainedbenefits RMB12457.6compared with the pattern of outdoor planting, Greenhouse-Ginger-Later ricepattern has gained benefits16780, which is better than the both two patterns below, increasingRMB3938than pattern of Greenhouse-Lagenaria Siceria-Later rice, and RMB6480than pattern ofGreenhouse-Melon-Later rice Using the Greenhouse-Ginger-Later rice pattern can improving soilenvironment effectively, reducing diseases and weed damage. At the same time, the expansion ofGreenhouse-Ginger-Later rice pattern is the objective requirements of stable production of grain, theimportant way of offer jobs opportunities and increase peasant's income, and also the best choice ofchange agriculture structures. However, the expansion of Greenhouse-Ginger-Later rice pattern has thefollowing problems, such as, the rural labors towards an aging trend and low-culture quality, largeInvestment on the labor and greater marketing risk leads the ginger-peasants have fear minds towards tothis pattern, lack of agricultural technology personnel, low degree of organization and industrialization,etc. To the above problems arising in the expansion, this article has been forwards the followingsuggestions to this pattern:(1) Introduce policies, Increase investment;(2) Pay attention to the planningand seek development, Expand the industry and find industry chain;(3) Enhance service relying onscience and technology, typical mode set up;(4) Cultivate organizations and promote the driven,Strengthen the professional cooperation;(5) Improve the quality and make brands, make betterinformation service.
