粮食生产新常态与转变粮食生产方式
New Normal of Food Production and Transformation of Food Production Mode
摘要
Abstract
The transformation of food production mode to promote the sustainable and stable development of grain production has great significance for ensuring national food security. The statistic data of grain production were used to analyze the current situation of grain production. The results showed that the grain production increased year after year,which mainly relied on paying material input and resources at a huge cost to the environment,showing the phenomenon“four high and two low”,such as high investment,high yield,high cost,high pollution and low rates of resource utilization,low benefit to grain farmers. The food production was affected by the restriction of resources and environment, per capita water resources was limited,and the regional distribution of resources and environmental conditions did not match. The food production went into the new normal what increased food security pressure. The grain production speed was changed by the rapid growth to slow growth,grain yield was in volatility period,food security policy was in a boosting stage. The conversion of food production mode must follow the grain development way that was taking both quantity and quality into account,improving the efficiency and benefit of grain,low carbon green,sustained,stable and harmonious. This paper put forward the countermeasures to change the grain production mode such as breeding of fine varieties,optimizing of planting structure,popularizing wa-ter saving and fertilizer saving technology,improving land productivity,labor productivity and resource uti-lization rate. The mode of food production could be changed which would realized the intensive use of land,the intensive cost-saving of material,the intensive loss reducing of environment and high-efficiency of technology in grain production.关键词
