| Abstract: |
| Setting up two jujube-cotton intercropping systems, we is planted 4 rows of cotton or 2 rows of cotton between two rows of jujube, to study on the yield formation and influencing factors of one-year jujube on intercropping cottons. The results indicated that there were no significant differences in leaf area index, SPAD value and photosynthetic physiological characteristics in different intercropping patterns before flowering period, while there was significant difference after flowering period. Compared with 1-row cotton, the plant height, leaf area index and net photosynthetic rate, stomatal conductance, transpiration rate and yield of cotton in Int-4 intercropping pattern decreased by 5.85%, 10.4%, 15.51%, 13.26%, 9.18% and 41.61%, and the intercellular CO2 concentration increased by 4.18%, respectively. The plant height, leaf area index and net photosynthetic rate, stomatal conductance, transpiration rate and yield of cotton in Int-2 intercropping model decreased by 3.10%、5.39%、11.80%、9.25%、6.09% and 47.74%, and the intercellular CO2 concentration increased by 0.84%, respectively. There was no significant difference in SPAD value. The economic income from high to low was: Int-4>Int-2>1-row cotton. Compared to Int-2, the plant height, leaf area index and dry matter of Int-4 decreased markedly by 2.85%, 5.29% and 6.85%, respectively. The yield of Int-4 was significantly increased by 11.73% compared to Int-2. However, there were no significant difference in SPAD value and photosynthetic physiological characteristics in Int-4 and Int-2. So we concluded that appropriate increase of cotton planting density is beneficial to the high yield of cotton in the jujube-cotton intercropping systems, it is also conducive to increase economic income. |
