Analysis of yield and efficiency of different planting methods of double cropping of barley and cotton

We use the cultivation mode of barley and cotton sleeve as the control,set the different planting pattern of two cropping of barley and cotton in the field experiment.to make comparisons of the cotton production efficiency in the different planting methods.The results show that the yield and efficiency of traditional nutritional bowl of cotton sleeve with barley and then transplanting were the highest;production quality and efficiency of media cotton seeding after bar ley and then transplanting were lower than the pattern of sleeve cotton with barley,but slightly higher than nutritional bowl of cotton seeding after barley and then transplanting;production and efficieney of direct seeding of mature cotton after barley were the lowest,the production of direct seeding of premature cotton after barley was equal with nutrition bowel of cotton seedling after barley and then transplanting,but the efficiency was matched with and nutritional bowl of cotton seedling sleeve with barley and then transplanting.In the current situation of large number of rural labor transferring and labor costs rising year by year,planting pattern of cotton sleeve with barley would be eliminated by production,cotton seeding after barley is suitable for mechanization and simplification,will have broad application prospects.
