黄河三角洲地区短季棉无膜栽培的种植表现和效益分析崔立华牛娜纪莲莲刘明云单尚东苏爱国赵秀梅刘庆年纪家华:通过短季棉鲁棉532覆膜晚播和无膜晚播种植模式与春棉鲁棉258常规种植模式进行比拟,探索适宜山东黄河三角洲地区气候地理条件的短季棉最正确种植模式,为大面积推广短季棉种植模式提供依据。结果说明,短季棉覆膜晚播种植模式对促进生长、增产、增效效果不突出;短季棉无膜晚播种植模式比其他模式可明显减少管理用工,降低植棉投入,比覆膜晚播效益略高,比春棉产量和效益均降低。建议采用短季棉无膜晚播与黑麦草〔饲草〕连作模式在黄河三角洲地区大面积推广,以提高短季棉的种植效益。关键词:黄河三角洲地区;短季棉;无膜栽培;种植表现;效益中图分类号:S562.04文献标识码:A文章编号:2095-3143〔2023〕02-0038-04DOI:10.3969/j.issn.2095-3143.2023.02.006Abstract:Bycomparingtheplantingmodeofshort-seasoncottonLumian532withtheconventionalplantingmodeofspringcottonLumian258,theoptimalplantingmodeofshort-seasoncottonsuitablefortheclimaticandgeographicalconditionsintheYellowRiverdeltaregionofShandongprovincewasexplored,whichprovidedabasisforthepromotionofshort-seasoncottonplantingmodeinalargearea.Theresultsshowedthattheeffectofshort-seasoncottonmulchinglateplantingmodeonpromotinggrowth,increasingyieldandincreasingefficiencywasnotprominent.Comparedwithothermethods,theshort-seasoncottonfilm-freelatesowingplantingmodecouldsignificantlyreducethemanagementlabor,reducethecottonplantinginput,slightlyhigherthanthefilmmulchinglatesowingbenefit,thanthespringcottonyieldandbenefitswarereduced.Inordertoimprovetheplantingefficiencyofshort-seasoncotton,itwassuggestedtoadoptthemodeoffilm-freelateplantingofshort-seasoncottonandcontinuousplantingofryegrass〔foragegrass〕intheYellowRiverdeltaregion.Keywords:YellowRiverdeltaregion;Short-seasoncotton;Nofilmcultivation;Plantingperformance;Benefit0引言隨着农业生产条件及气候条件的不断变化,农作物的种植模式也在不断改变,总体表现为日趋机械化、轻简化。棉花常规品种生育期长,需春季播种。而黄河三角洲植棉区往往春季干旱、缺水,风多、风大,散墒快,为保证一播全苗,需要地膜覆盖,由于棉田连续多...
