Dryland Wide Car Broadband Planting Mode High Yield And Efficient Mechanism

With the decline of arable land area and the continuing increase of population, the request to improve the crop yields per unit area is becoming more and more urgent. The cultivation model that width theater box wide band are used has the characteristics of high yield and high efficiency and has an important position in agricultural production. The randomized block design, the combination method of field experiments and laboratory analysis has been used in this experiment, the Morphology, the photosynthetic characteristics and the marginal effect of the corn varieties with different plant type have been studied in the paper. The fissure design is used in the study that how to choose corn varieties, the influence on the growth and development as well as the economic impact of different crop Growing portfolio and Separating plot specification in the cultivation model that width theater box wide band are used in dryland area. In the cultivation model that width theater box wide band are used in dryland area. The aim is to deeply understand the essence of the interaction between crops in the cultivation model that width theater box wide band are used in dryland area, to provide a scientific basis that can optimize and improve the productivity in the cultivation system that width theater box wide band are used in dryland area and the efficiency of resource use. The results show that:1 The cultivation model that width theater box wide band are used can improve the conditions of ventilation and transmission of the corn groups, and improve leaf photosynthetic performance of the maize, help the individual plants of corn to develop fully. The high yield of corn is achieved through giving full play to a marginal effect. The flat corn varieties which are sensitive to the marginal effect in the cultivation model that width theater box wide band are used can get nearly the same yield as the net cultivation. Access mode for the single equivalent yield. 2 The photosynthetic characteristics in plant pattern of width theater box wide band of maize, the unique group structure is advantageous to the maize leaf area increases, chlorophyll content elevating and photosynthesis rate enhancement.3 Different plot widths have a certain shade effect on the broadband crops in the cultivation model that width theater box wide band are used, the selection of broadband crop has decisive role to achieve high yield and high efficiency, the cultivation model that intercropping maize with pepper can get the most economic benefits, which is 15,852 yuan per hectare.4 The interaction between crops has some effect to the yield of corn in the cultivation system that intercropping maize with pepper. The contribution rate of the influent elements above the ground to the yield of corn is 34.6%, the contribution rate of the underground factors to the yield of corn is 65.4%.
