From 1994 to 2000, the technology of intercropping rice and rice in the mountainous areas of Dabie and Wannan in Anhui Province was studied. The results showed that the leaf area and the vertical distribution of the root system in the intercropping system were divided into upper and lower strata, the spatial structure was reasonable, Which is favorable for the system to make full use of the resources of land, light, heat, water and gas. The relative light intensity in midsummer decreases with the increase of relative humidity, which provides more suitable ecological environment for tea tree growth. Quality improvement. In the 5-year-old young tea plantation, an average of 330 kg of rice can be produced per hm2 per year and the net income can be increased by more than RMB230 0 yuan, which is of great significance to solving the problem of food and clothing shortage in poor and deficient mountainous areas with less cultivated land per capita
