Analysis Of The Potential Production Of Sugarcane In Guangxi Based On AEZ Model

According to the 10 years from 2004 to 2014 basic meteorological data of 25 m eteorological site in GuangXi, Combined with the Agricultural Ecology Zone model is widely used to estimate the photosynthetic production potential, the light warm climate pro duction potential of sugarcane by means of Excel, Access database, GIS software. Data on the rate of various interpolation methods using the trial level meteorological and cli matic elements, sugarcane production potential and different levels potential for spatial i nterpolation conditions try a variety of interpolation (such as radial interpolation, polyno mial method, ordinary Kriginginterpolation method and parameter), select the appropriat e interpolation, and then theinterpolation grid map.Then the interpolation results are deriv ed for the climate production potential of climate production potential distribution map w ith rate vector layer of Guangxi.The results of the study show that:1) All levels of sugarcane production potential distribution is obvious in GuangXi c ounties, the performance from south to north is decreasing on the whole, but the local i s different. The average photosynthesis, light temperature, climatic potential productivit y of sugarcane were 178.81 t/hm2,168.98 t/hm2,152.34 t/hm2 in GuangXi.2) The photosynthesis, light temperature, climatic potential utilization generally show ed the distribution trend of increase from east to West in the space, and the average val ues were 31.66%,33.58%,37.71%.3) Calculation and analysis of average light, heat, rainfall of sugarcane utilizatio n were 0.578%,8.04%,44.51 kg/mm/hm2 in GuangXi.4) The eastern part of Guangxi’s climate resources of sugarcane in reality utilizatio n rate is not high, but a great potential for development in the region; In the central and western regions, the utilization rate is relatively high levels of sugarcane production potential, the utilization rate of resources is relatively high, but the reality of the develo pment potential of the area is low. To improve the yield of sugarcane in Guangxi, in the short term, the most effective and efficient way is to improve the efficiency of resour ce utilization of sugarcane production p-otential of the eastern region by the way of im proving the photosynthetic capacity, research and development of new varieties, crop rot ation and interplanting and so on. From the point of long-term development, to increas e the production potential of the northern region of GuangXi’s development efforts, can be used to strengthen the investment in science and technology, research and developme nt of new varieties and improve the promotion of advanced cultivation techniques; In the actual production, the extreme weather conditions cann’t be artificially controlled, so we should strengthen field management.
