| In order to study the intercropping effect between root restriction cultivation grapevine and winter wheat,winter wheat(Yannong 19) was intercropped between 4 m wide rows of root restriction cultivation grapevine(Zuijinxiang，North-south planting) for 5 years.The field microclimate, growth and yield of winter wheat at jointing stage, booting stage, grain filling stage and maturity stage, and temperature and humidity, net photosynthetic rate and yield of grapevines at germination, flowering,version and ripening stages were investigated, and the economic benefits of intercropping mode were analyzed.The results showed that the intercropping model had a tendency to reduce the canopy temperature and increase the canopy relative humidity of winter wheat, but the impact was not significant. From the grain filling stage of winter wheat, the grapevines shaded the east and west sides of winter wheat planting areas between rows in the morning and afternoon,respectively, and the average daily light intensity of intercropping winter wheat canopy was about 90% of that of monocropping winter wheat. The growth and development indices of intercropping winter wheat were better than those of monocropping winter wheat, and intercropping winter wheat showed obvious edge advantage at booting stage. The yield components of intercropping winter wheat were better than those of monocropping winter wheat, and the net area yield was significantly higher than that of monocropping winter wheat, and the edge advantage was significant, with an increase rate of 35%.Intercropping mode had no effect on temperature, humidity, net photosynthetic rate and yield of root restriction cultivation grapevine.The economic benefit of intercropping mode was 16.3 times of that of monocropping winter wheat, and 5.8% higher than that of monocropping root restriction cultivation grapevine.On the whole, the intercropping model did not affect the temperature and humidity, net photosynthetic rate and yield of grapevine,but increased the growth and marginal effect of winter wheat, resulting in higher economic benefits, which was suitable for popularization. |
