Choice Of Wheat Growers Using No-till Technology And Impact On Yield

As a major food crop,wheat production has become an important focus of China's food security issues.Wheat cultivation areas are mostly distributed in dry farming areas.They face climatic characteristics such as insufficient rainfall and uneven rainfall all year round.In order to pursue high yields of crops,people have increasingly emphasized intensive cultivation.Excessive use of mechanical equipment not only reduces soil water storage and food production,but also exacerbated soil erosion.The promotion of no-tillage technology is an important measure to effectively alleviate the degradation of cultivated land quality and achieve sustainable development of cultivated land.Therefore,exploring the factors that affect farmers' adoption of no-tillage technology and evaluating the effect of no-tillage technology can provide theoretical guidance for the formulation and implementation of no-tillage policies,which has important practical significance for the sustainable development of agriculture in China.The total wheat sown area in Shaanxi,Henan,Anhui,Jiangsu,and Shandong accounts for 64.8% of the country's total.It is an important wheat production area in China and a major dry farming area.Therefore,the five provinces are selected as sample provinces in this paper.Field surveys were carried out in 26 villages.First,the descriptive statistical methods were used to analyze the current status of wheat farmers' awareness of no-tillage technology,and to explore the farmers' understanding of no-tillage technology,the reasons for their adoption,the reasons for their non-adoption,and their attitudes.The results show that the majority of farmers adopt no-till technology,accounting for 62% of the interviewed farmers.Farmers mainly gain knowledge about no-till technology through television propaganda and rural broadcasting;reducing farmland costs is the main reason for choosing no-tillage technology and not knowing no-till technology is the main reason for choosing no-tillage technology.After receiving relevant publicity and knowledge popularization,the vast majority of farmers who have adopted no-tillage technology are still willing to continue to use it,and more than 1/3 of those who have not adopted it are also willing to try No-till technology.Secondly,using the hierarchical structure model,the empirical analysis is made on the factors that affect farmers' adoption of no-till technology from two levels: the characteristics of the farmers and the village environment.The results show that 42.9% of the reasons for the differences in the behavior of no-till farming technology from farmers are environmental factors from different villages,indicating that both the characteristics of the farmers and the village characteristics will affect the no-till farming behavior of the farmers;Farmers who have received propaganda and training and have a large total cultivated land area and a small number of arable land will be more inclined to adopt no-till technology;the distance between village-level villages and counties(districts)and whether to apply for agricultural insurance will be significantly strengthened or reduce the degree of influence of peasant household level characteristics on adoption of no-till technology.Finally,an endogenous transformation model was used to construct an econometric model of the effect of no-tillage technology on wheat output by wheat growers,and the average treatment effect of no-tillage technology on wheat output was obtained.The results show that the average yield per acre of wheat using no-till technology is 434.02 kg,which is about 30 kg more than the average yield per acre of wheat without no-till technology.If adopters do not use no-till technology,their wheat yield will be reduced by 7%,which confirms that no-till technology can increase wheat yield.
