麦棉不同种植方式的产量与效益比较

以小麦棉花套栽种植模式为对照,设置麦棉两熟不同种植方式,在大田试验条件下,比较分析了不同种植方式的棉花产量和两熟效益.结果表明,传统的营养钵育苗麦套移栽棉产量和效益均最高;麦后基质育苗移栽棉产量和效益低于套栽棉,但略高于麦后营养钵育苗移栽棉;麦后中熟直播棉产量和效益均最低,麦后早熟直播棉产量与麦后营养钵育苗移栽棉相当,但效益与营养钵育苗麦套移栽棉相当.在当前农村劳动力大量转移及劳动力成本逐年攀升的形势下,麦棉套栽种植方式必将会被生产淘汰,麦后棉适宜于机械化与轻简化,将有广阔的应用前景.

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.
