Influence Of Intercropping Between Grape And Wheat On Wheat Microclimate,Growth And Production

Grape wheat intercropping is an excellent intercropping model,but at present there are few studies in China.In order to demonstrate the advantages of the intercropping model,provide a theoretical basis and data basis for the promotion of this model,and provide new way of income for food growers in Henan at the same time.This study explored the effects of intercropping patterns of Vitis vinifera and Triticum aestivum based on root zone restriction on wheat microclimate environment and growth and production.Root restricted grape ?Flaming Muscat‘ and wheat ’Wheat Zheng 113‘ are chosen to intercrop together.Changing of wheat microclimate and growth are analyzed to judge whether there is bad influence on wheat,and total yield and output value are counted to prove the advantage of intercropping.As the result shows,grape wheat intercropping slightly reduces the temperature of wheat canopy microclimate environment and has an effect on humidity.Intercropping has a shading effect on the whole wheat line.The degree of shading increases with the shorter distance from the grape row.The light intensity at the strongest shade is 65% of the control group,while the overall shading rate is only 20%.So the degree of shading is weak.Because the grapes use a root-limited planting method,the intercropping does not affect the water and fertilizer resources of the wheat.Intercropping grapes have a certain negative impact on the photosynthetic rate of wheat flag leaves,but it‘s found through accurate modeling that the degree of negative impact is limited.It can be considered that the intercropping has little effect on the photosynthetic rate of wheat flag leaves.Intercropping grapes significantly affect the plant height of wheat,which makes the wheat line slightly higher in the middle and slightly lower on both sides,but has little effect on the aboveground biomass,underground biomass and ear weight of wheat,indicating that the intercropping grapes would not be obviously affect the vegetative growth and reproductive growth of wheat.The grape wheat intercropping will significantly improve the economic benefits of the wheat field.The net income of intercropping field is 8.4 times more than the single crop wheat field,and the wheat yield of intercropping field is only 15% less than single crop wheat field.Therefore,grape wheat intercropping is a kind of intercropping mode with weak influence on wheat and strong economic efficiency,which is suitable for promotion.
