Research On The Relationship Between Grain Yield, Nutrient Efficiency And Economic Benefit In Hunan

Food is the most basic living consumption of humans, a country's food problem is related to the national economy and the people's livelihood. We know that agriculture is the foundation of the national economic development, and it is the foundation of food production, so the food production is an eternal subject which is related to the survival and development of a country. Since the founding of new China, China's grain output has fluctuated, which not only restricts the development of the national economy, but also to food producers and consumers have brought a very negative impact. The fluctuation of grain output in China is of great significance to food price, which is of great significance. Firstly, the paper analyzes the relationship between three kinds of crop yield, nutrient efficiency and economic benefits by using the first hand data of 6 regions of Hunan. Secondly, the factors that affect the grain yield, nutrient efficiency and economic benefit are discussed. The paper discusses the factors that affect grain yield, efficiency and economic benefit. The main results are as follows:At present, there are only a few plots of land that can achieve high yield, high nutrient efficiency and high economic benefits in the grain crop production in Hunan. Yiyang, Changde, Loudi and Shaoyang of early rice and late rice farmers can achieve at the same time, high yield, high efficiency and high charge state, the proportion of households who were less than 20% and low production, low efficiency and low income households, the proportion of more than 30%.Research showed that various factors influenced relationship between rice production, efficiency and benefits, mainly including grain acreage and labor input in agricultural production, farmers technical quality, technology and government support, and natural disasters.We put forward some feasible suggestions on improvement of production, efficiency and effectiveness. You can adjust the amount of fertilizer to improve fertilizer efficiency; strengthen farmland protection; enhance agricultural crop promotion efforts; strengthen water conservancy construction efforts to improve the ability of agriculture to withstand natural disasters; formulate preferential policies and support policies; Hunan grain cultivation technology extension service system...
