Objective: The purpose of this project is to study the effects of different irrigation models of jujube-cotton intercropping in ecological areas on the temperature and humidity and determine the ecological result of different irrigation models to the environment in order to provide some scientific basis for optimum water-saving irrigation model for jujube-cotton intercropping. Method: Three EL-USB automatic measuring system of temperature and humidity was established in the different positions in treatment 1 - jujube garden, treatment 2 - double water pipes in one line, treatment 3 - spray, treatment 4 - ditch irrigation, treatment 5 - cotton, EL-USB automatic measuring system of temperature and humidity of different distances from tree row to be monitored for 3 days in a row. Result: Effects of east-to-west jujube row on micro-ecological areas temperature are: the south of Jujube > the north of Jujube > Jujube row, and humidity: jujube row > The north of Jujube > The south of jujube; There was a negative linear correlation between humidity and temperature. Effects of different irrigation models on micro-ecological areas temperature of Jujube-cotton intercropping are: treatment 5 > treatment 1 > treatment 4 > treatment 3 > treatment 2, and humidity: treatment 2 > treatment 3 > treatment 4 > treatment 1 > treatment 5. Conclusion: Results showed that the crown shading of a east-to-west jujube row affected micro-ecological area temperature and humidity differently with different directions from tree row. Generally, temperature is the south of Jujube > the north of jujube > jujube row. There was a negative linear correlation between humidity and temperature. The temperature of jujube-cotton intercropping is lower than that of the single cotton model, but the humidity is higher. The treatment of spray and the treatment of double water pipes influence temperature and humidity greatly, which was advantageous to increase the jujube fruit setting rate.
