摘　　要：本试验针对陕西关中棉区气侯特点与种植习惯,研究了夏棉春育、麦林移栽、麦后覆膜等项麦棉集约式两熟栽培技术,扩展夏棉生长的时空和热量条件。三年试验结果表明,在"三密一稀"满幅荷种植的麦田,麦收前育苗移栽、麦后采取覆膜管理等措施,可增加≥15℃有效积温535.6～525.8℃,使夏棉皮棉产量达1197.5～981.0 kg·hm^(-2)。比麦林点播棉籽的一般露地管理夏棉增产皮棉89.4%,较好的解决了当地棉麦两熟栽培有效热量不足的最小限制因子,实现了麦棉集约式两熟作务,提高了土地等资源的利用率。In accordance with the climate and the customs of planting in cotton area of GuanZhong. Shaanxi, the experiment studied the intensive cuhiaton techniques about wheat-cotton growing system incuduing summer-cotton seedling in spring, cotton seed transplanting to wheat fiebl and plastc mulching after wheat maturity and so on, while the season and space and the condition of calovific capacity on summer-cotton growth were expanded by this techniques. The result of three years experiment proved that some measures such as summer - cotton seedling in spring, cotton seeding transplanting to wheat fiebl and plast mulching after wheat matunity would increased the effective accumulated tempera- ture over 15℃ （ from 535.6 to 525.8 ）, and made summer-cotton yields reached 1197.5 to 981.0 kg · hm - 2. The production of lint summercotton have increased 89. 4% than the general ground manage which cotton seed have sown on wheat fiebl. Firestly, the techniques have more better solved the least limiting factor which the effective heat at local area has insufficient. Secondly, it has realized the wheat-cotton double maturity. Tirdly, it has increased the interest rate of natural resource.
