贵州省玉米生产现状及单产提升技术途径探索OA

Maize is an important grain crop in Guizhou province,so improving the level of maize yield is of great significance for ensuring food security and promoting sustainable agricultural development.The current situation of maize production in Guizhou province was introduced,and the change trends of maize planting area,yield and per unit yield in Guizhou province were predicted using the autoregressive integrated moving average(ARIMA)model.Focused on the reality of maize production in the mountainous areas of Guizhou province,it was analyzed that maize production in Guizhou province was mainly limited by factors such as poor farmland quality,low coverage of good varieties,insufficient density,low rate of technology in place,frequent occurrence of disasters and relatively backward facilities.It was proposed that improving the yield level of maize in Guizhou province should conduct from 4 aspects:breeding high-yield and excellent varieties,strengthening the integration of high-yield technologies,strengthening facility investment and leveraging policy guarantees.What's more,3 main promoted technologies for maize cultivation in Guizhou province were introduced.Above results provided ideas for the construction of high-yield and high-efficiency cultivation technology system of maize in Guizhou province,and provided theoretical support and technical guidance for further improving the level of maize yield and guaranteeing food security in Guizhou province.
