不同种植模式对机采棉产量和纤维品质的影响

Effects of Different Planting Patterns on Yield and Fiber Quality of Machine-Picked Cotton

为考察不同种植模式对机采棉的产量和纤维品质的影响,并优化机采棉的种植模式,开展了田间小区试验。试验设置了1膜3行、1膜4行、1膜6行等3个处理,每个处理重复3次。结果表明:1膜6行处理的皮棉产量最高,1膜3行处理在单株铃数、单铃质量、衣分等方面具有一定优势,不同处理间纤维品质性状变异不大。1膜6行种植模式具有稳产、高产的特点;建议优化1膜3行种植模式的种植密度,改进栽培方式,选择适宜种植的棉花品种。

In order to investigate the effects of different planting patterns on the yield and fiber quality of machine-picked cotton,and optimize the planting pattern of machine-picked cotton,a field plot experiment is carried out.The experiment set up with three treatments of 1 film 3 rows,1 film 4 rows and 1 film 6 rows,and each treatment is repeated for three times.The results show that the lint yield of 1 film 6 rows treatment is the highest,1 film 3 rows treatment has certain advantages in the boll number of single plant,single boll weight,lint percentage,etc.,and the fiber quality traits do not vary much among different treatments.1 film 6 rows planting pattern has the characteristics of stable yield and high yield.Therefore,it is recommended to optimize the planting density of 1 film 3 rows planting pattern,improve the cultivation method,and choose the suitable cotton varieties for planting.
