棉花高密度栽培在棉花高产县及新疆的实践

新疆地处欧亚大陆腹地,干旱少雨、昼夜温差大、春季气温回升慢、倒春寒天气频繁、土壤往往不同程度返盐返碱,基层植棉单位又往往不按农田生态屏障保护程度确定适宜的冬、春灌农田次序,不能合理确定棉花的始播期及不同类型棉田适播期,棉田整地质量、播种质量均因各种原因达不到棉花播种对待播棉田要求,棉花播种后往往出现不同程度的烂种、缺苗、断垄;在棉田出现不同程度的烂种、缺苗、断垄严竣形式下,新疆的棉花新品种(系)的试验、示范繁殖人员在极为被动情况下,通过“一穴留双株”等方式解决了新品种(系)引种试验、示范棉田大规模缺苗、断垄后的棉田有效保苗株数问题,历经多次失败,最终多次刷新了全国棉花高产纪录,创造出了棉花高密度栽培新模式,为新疆棉花高产栽培创出了一条新路子。

The Cotton High Density Planting in High Yields County and Xinjiang

Xinjiang locates in interior region of Europe and Asia, Which weather is dry and little rain; the temperature of day and night is wholly different. The spring air temperature backs up slowly, pour the cold weather in spring high frequency, the usually different degree in soil returns the salt and alkali, The basic level plants the unit of the cotton to usually Can''t according to farmland ecosystem natural cover the protection the degree again certain winter and spring flooding farmland order of sequence, can''t be reasonable certain the cotton starts to seedtime and different type the cotton farmland the fitting seedtime, cotton farmland soil and seeds the quantity all because every kind of reason can not reach the cotton sow seed for sow the cotton farmland quantity request, cotton after sowing seeds the putrefy seeds that usually appear the different degree, lack the seedling; Under Rigorous situation,it appears the putrefy seeds in the cotton farmland, lacking seedling , Under the extremely passive circumstance in Xinjiang the experiment and the demonstration breeds the personnel, passes" a cave stays two of plants" etc. Methods resolved the new variety( strain) experiment and the demonstration the cotton farmland the large-scale lacking the seedling of the cotton farmland protects the seedling plants number few problem effectively, experiencing successively to fail many times,and broke the national cotton the high yields the record many times, creates the new mode in high density planting in cotton, is high for the cotton of Xinjiang to yields planting create a new road.
