山西南部棉区 ,小麦收获后移栽棉花 ,每hm2 收获皮棉 90 4 5～ 112 6 6kg ,一般为 10 70kg左右 ,较直播棉每hm2 增产 375kg以上。麦后移栽棉花的增产机理 ,主要是从本田以外的苗床获得 (10 0 0～ 130 0 )℃的总积温和 4 0d左右的生育期 ,从而有效地弥补了麦后直播棉积温和生育期不足的缺陷。工程化栽培技术主要是机制土钵、机械移栽、双株留苗、优种配套和促早管理为一体的综合技术。
Cotton fields in southern Shanxi, wheat transplanted after harvesting cotton, lint per hm2 harvest 90 4 5 ~ 112 6 6kg, generally about 1070kg, more than 375kg per hm2 than direct-seeded cotton yield. The increasing yield mechanism of cotton after transplanting wheat is mainly obtained from the seedbed outside Honda (10 0 ~ 130 0) ℃ total accumulated temperature and 4 0d about the growth period, so as to effectively compensate for the direct seeding cotton cotton warm and growth period Insufficient defects. Engineering cultivation techniques are the main mechanisms of soil pots, mechanical transplanting, Shuang Zhu Li Miao, excellent kinds of supporting and early management as an integrated technology.
