摘要
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。
In the sourth of shanxi, after harvest of wheat, transplanting cotton can obtain lint cotton 904.5-1266.0 kg/ha, generally obtain 1 050 kg or so, lint cotton yield can be increased by over 375.0 kg/ha, compared with that of direct seeding. The machanism of increasing yield for transplanting is mainly to get accumulated temperature 1 000-1 300 ℃ on seed beds besides in the fields, which could efe out the accumulated temperature and the growth stage of the seeding cotton after harvest of wheat. The engineering culture technics is a set of comprehensive technics i.e. to make plant balls with machine, mechanically transplant, set two plants/hill, use good variety and enhance early maturity.
