Abstract:

To continuously build the internal quality of cultivated land, improve its comprehensive production capacity, explore the productive potential and the yield increasing potential of crops, and provide reference for the structural adjustment of planting industry, this paper took Wuxiang County of Shanxi Province as an example to optimize the layout of planting industry. Firstly, the distribution of cultivated land quality in Wuxiang County was analyzed, including the general situation of cultivated land resources, the quality grade of cultivated land and the topographic condition in each township. Then the change of the year-on-year growth of crop yield per unit area in Wuxiang County from 2015 to 2019 was examined. The comprehensive comparative advantage index method was used to calculate and study the production scale advantage index, production efficiency advantage index and comprehensive comparative advantage index of millet, corn, sorghum, soybean, potato, vegetable, oil plants, medicinal materials, jujube, watermelon, walnut and apricot in comparison with same crops in other parts of China. Finally, by making full use of the production conditions of cultivated land quality in different regions of Wuxiang County and the calculation results of the comparative advantage of millet, corn, sorghum, potato, medicinal materials, apricot and walnut in the whole country, the layout strategy was adjusted. Three major planting industry layouts were worked out for Wuxiang County, namely, “the efficient and comprehensive cluster area, the characteristic and quality demonstration area and the development and protection area”, thus to establish the high quality and high efficiency planting industry base and cluster. By transforming the advantage of cultivated land quality and the comparative advantage of crops into economic advantage, the optimum planting pattern of “expanding the scale advantage, ensuring the yield advantage and strengthening the quality advantage” was constructed to improve the grain yield, highlight the characteristic varieties, and increase the agricultural income.
