Effects of planting density and varieties on the morphological structure of vegetative organs and yield of machine-picked cotton in northern Xinjiang
摘要
Abstract
[Objective]This research aims to investigate the effects of planting density and varieties on the morphological structure of vegetative organs and yield of machine-picked cotton in northern Xinjiang.[Methods]Field trials were conducted in 2022 and 2023 at Wulanwusu Agricultural and Meteorological Experiment Station and Manas Agricultural Experiment Station,respectively.Two varieties,CCRI 127(V1)and Xinshi 518(V2),were selected,and three planting densities were designed as 11 plants·m-2(D1),22 plants·m-2(D2),and 28 plants·m-2(D3),respectively.The effects of different treatments on leaf length,petiole length,petiole diameter,internode length,and internode diameter of cotton main stems and fruiting branches as well as yield traits were compared.[Results]In 2022 and 2023,V1 showed the smallest leaf length,petiole length,and internode length of main stems and fruiting branches under D1 and D2 treatments,respectively.In 2022,V2 showed the smallest leaf length,petiole length,petiole diameter,and internode length of main stems and fruiting branches under D3 treatment.In 2023,V2 showed the smallest petiole length and internode diameter of main stems and fruiting branches under D3 treatment.Leaf length and internode length of main stems and fruiting branches showed V1≥V2 under the same density in 2022.Leaf length,internode length,and internode diameter of main stems and fruiting branches of V1 and V2 were not significantly different under the same density in 2023.The lint percentage of V2 was significantly higher than that of V1 under the same density both in 2022 and 2023.Seed cotton yield and lint yield of V1 and V2 in 2022 as well as that of V2 in 2023 increased with the increase of planting densities.Seed cotton yield of V1D3 treatment was highest in 2022,and relatively higher in 2023.V2D3 treatment had the highest lint yield in 2022 and 2023.[Conclusion]The preferred planting density under the conditions of this experiment was 28 plants·m-2,and the lint yield of Xinshi 518 was higher.The results of this study can provide a support for the improvement of the CottonXL model,and provide a reference for the selection of appropriate varieties and planting densities of machine-picked cotton in the northern Xinjiang.关键词
