超宽膜对棉田土壤水热分布、棉花生长及品质的影响
Effect of ultra-wide film on soil heat and water distribution and the growth and yield quality of cotton
摘要
Abstract
To investigate the effects of different film widths on soil moisture and temperature distribution,cotton growth and development,cotton yield,and fiber quality,a field production experiment was conducted in 2022-2023 using 4.40 m ultra-wide film under conventional management practices in cotton fields with medium yield levels in northern Xinjiang.The 2.05 m conventional wide film was used as the control(CK).Soil moisture content and temperature in the 0-60 cm soil layer were measured under different treatments,and changes in cotton agronomic traits,seed vigor,yield components,and fiber quality were investigated.The results showed that the soil temperature in the 10-40 cm layer under the ultra-wide film was significantly higher than that under the conventional wide film.At 30,60,90,and 120 days after cotton emergence,the mass moisture content in the 40 cm soil layer increased by 1.24％,2.45％,1.69％,and 1.53％,respectively.The emergence rate and boll setting rate of cotton under the ultra-wide film increased by 5.10％and 4.16％,respectively.The proportions of middle and upper bolls increased by 2.18％and 3.52％,respectively.Over the two years,the yield increase reached 13.03％and 5.59％,with actual economic benefits per 667 m2 reaching 379.55 yuan and 125.00 yuan,respectively.Additionally,under the ultra-wide film treatment,the germination rate,germination index,and seed vigor of cotton increased by 49.81％,54.48％,and 53.92％,respectively,compared to the conventional wide film,with the differences being statistically significant(P≤0.05).In conclusion,the 4.40 m ultra-wide film has significant application value in improving soil moisture and temperature conditions,promoting crop growth and development,and enhancing cotton yield and quality.This study provides a basis for the future large-scale promotion of ultra-wide film cultivation technology.关键词
