Technical Economic Analysis Of Grain Safety Control In The Southwest Of Guizhou

The grain security problem is the world question, and also is a district question at the same time. This article took the rice as the example, which applied the technology economic principle and combined economics with the cultivation, then adopted the research technique of the qualitative and quantitative analysis in the massive investigations foundation. To the rice output course, the different stage technology constitution (technical combination) and rice technology factor had carried on the commentary and the analysis to the contribution rate of output in southwest of Guizhou from 1980 to 2003. The result indicated: (1) All breakthrough of each output in the southwest of Guizhou had the close relations with the breed renewing , the application promotion of new technology (cultivation technology and so on) and the increase of matter inputs. But in the three of the improved variety, the matter inputs and the management technology , the matter inputs (applies fertilizer) was the highest to the output contribution rate, reaching 85.10% (115.2kg/667m~2). The heredity improvement is 22% (43.7kg /667m~2). And the management technology is lowest to the output contribution rate, only 19.9%. That indicated the matter (chemical fertilizer) inputs was valued but the management (cultivation technology) was despised in the southwest of Guizhou rice production, otherwise that showed the application promotion of management technology was the essential factor in increasing the rice output in the southwest of Guizhou; (2) Looking from the rice technology factor to the output contribution rate in the southwest of Guizhou, there was a very big disparity in each area, and the area of comparative higher rice producing attached importance to the management technology comparatively, but backward area more relied on the input to chemical fertilizer in the rice production. Through the comparison analysis, at present the southwest of Guizhou rice producing horizon difference, it was the difference between the technical arriving rate and the peasant accepting technology; (3) The rice output breakthrough key was grabbing the innovation of technology and the application promotion resolutely in the foundation of the stable existing matter(chemical fertilizer) inputs, and the key point was the technical indigenization, namely making the existing technology formed easily simplification (fool) technology which was accepted by the peasant easily, and enhancing technical arriving rate. (4) In the near future, the rice will break through 500kg /m~2 in the southwest of Guizhou, and its essential technology will be: The first, choosing the ear variety of tiller medium, big ear of grain, more big the weight of thousand seeds (heavy); The second, promoting the formula for fertilizer. Namely "stabilizing the nitrogen, increasing the phosphorus, making up the potassium", enhancing the phosphorus potassium fertilizer in total...
