Abstract:
【Objective】 This project aims to study the effects of peanut growth and development, leaf physiological characteristics and yield of different fruit trees.
【Methods】 The conventional peanut varieties in Xinjiang Toksun County was taken as the test material, through the planting mode of peanut intercropping among three fruit trees: apricot, jujube and grape, the changes of agronomic properties, soluble protein content, malondialdehyde and antioxidant enzyme activities of peanut and the yield characteristics of peanut were analyzed.
【Results】 Intercropping with different fruit trees significantly affected the main stem height, branch number and stem diameter of peanut.The number of branches of peanut in apricot intercropping was 190% and 60% higher than those in jujube and grape intercropping, and the length of main stem was 26% and 13% lower; Among different treatments, the main stem height of peanut was inversely proportional to the number of branches and stem diameter, and the number of branches was directly proportional to the stem diameter.The growth law of lateral branch length was that the growth period from seedling stage to pod setting stage was rapid growth period, and the growth period from pod setting stage to mature stage was slow growth period; under the intercropping of different fruit trees, the protective enzymes of peanut leaves showed a downward trend as a whole.The SOD enzyme activity of peanut intercropped with apricot and grape was significantly higher than that of peanut intercropped with jujube at all growth stages; Under the intercropping of different fruit trees, the number of fruit per plant and yield per plant obtained by intercropping peanut with apricot trees were the largest, 43.33 and 116.23 g, respectively.
【Conclusion】 Apricot trees with suitable crown and age and less shade are the most suitable for intercropping peanut.The combination of scientific and reasonable pruning and water and fertilizer management is an important prerequisite for intercropping peanut.
