摘 要:通过以中棉所53为试材,设置油后直播、油后基质育苗移栽、油后营养钵育苗移栽和油棉营养钵育苗套栽4种种植方式,进行棉花生长发育和产量及效益的分析。结果表明:油后营养钵育苗移栽可获得较高的收益和纯收益;基质育苗移栽投入较少,纯收益较高;油棉营养钵育苗套栽与油后营养钵育苗移栽相比并没有优势;油后直播方式虽然产量低,但人工投入少,生产成本低,适合劳动力缺少的家庭或农场应用,但要考虑天气因素慎重选择。Zhongmiansuo NO.53 was used as test material.Four planting patterns were designed: direct seeding after rape seedling,raising with soilless-substrate and root-naked transplanting after rape seedling,raising and transplanting nutritive soil-cubes cotton after rape seeding,and interplant nutritive soil-cubes cotton with rape seeding.Making cotton growth development,yield and effectiveness analysis,the results indicate that raising nutritive soil-cubes after rape seeding would obtain higher benefit and net income,soilless-substrate and transplanting cotton have lower investment but higher net income.Interplant cotton with rape has no advantage when compare to raising nutritive soil-cubes cotton after rape seeding.Direct seeding after rape seedling has low manpower devotion and production cost,but the yield is also low,this pattern is suit for the families and farms which is lack of work force,consider the factor of weather,and be cautious.
