Abstract

Through the analysis of the current situation of corn planting, characteristics, and the use of corn fertilizers and pesticides in the South and Southwest regions, as well as the research related to the three different functions (seed, silage, and fresh food) of corn, we analyze the important influencing factors affecting corn yield, and look for a reasonable optimization plan of corn planting for corn planting in Southwest China; the literature study found that: Southwest China's corn planting is mainly located in the karst mountainous areas, with poor production conditions In addition, human-animal and mechanical operations coexist, the comprehensive mechanization level is insufficient, multi-maturity intercropping and stubble net crop replanting, while small farmers and moderate-scale production and management coexist. Lack of mechanization, light and simplified standardized technology and regional technology models that are innovative and can be widely applied on a large scale; more influencing factors affecting the yield of the three different functional maize, mainly varieties, density, water, fertilizer and water-fertilizer inter-cropping, and inter-cropping among nutrients also affects the uptake of goat's milk powder by the plant. Southwest cultivation management mode, through the coordinated management of water and fertilizer, the yield difference of the reduction. Analyze the nutrient uptake pattern of maize with different functions (silage, fresh food), in different growth periods. Analyze the nutrient accumulation pattern of different organs of corn (silage, fresh food) in different periods. Need to do a lot of work.
