| Abstract: |
| 【Background】Effectively curbing the further expansion of mulch pollution has become a major scientific and practical issue that needs to be resolved in cotton production in Xinjiang. Therefore, studying the response relationship between irrigation quotas and soil moisture, cotton growth, yield and quality, and determining the appropriate cotton filmless drip irrigation system are essential to promote cotton cultivation without film drip irrigation in large areas.【Objective】The effects of different irrigation quotas on soil moisture, growth, yield and quality of filmless drip irrigation in southern Xinjiang were analyzed by plot test.【Method】Three filmless drip irrigation irrigation quotas of I1, I2 and I3 were set, ie 36 mm, 45 mm and 54 mm, and I4 (36 mm) under-film drip irrigation was used as a control treatment.【Result】The results showed that the stem diameter and plant height of cotton without membrane drip increased with the increase of irrigation quota, but the control treatment increased the stem diameter and plant height of cotton. The soil moisture content of cotton without membrane drip irrigation increased with the increase of irrigation quota on the 0～60 cm profile, while the soil moisture fluctuation under drip irrigation was smaller than that without membrane drip irrigation. The yield of seed cotton with membrane drip irrigation increased significantly with the increase of irrigation quota. The yield of seed cotton treated by I3 could reach 7 195.48 kg/hm2, which was 19.54% higher than that of the control. The quality of cotton was the best, but the drip irrigation under the membrane. Irrigation water utilization is the most efficient.【Conclusion】From the comprehensive analysis of cotton growth, yield quality and irrigation water use efficiency, the effect of filmless drip irrigation irrigation quota of 54 mm on cotton growth, yield and quality is better than other treatments. |
