摘　　要：为探究压缩对籽棉品质的影响因素与规律,以含水率、含杂率及压缩密度为试验因素,以棉籽破碎率、纤维长度、马克隆值、伸长率、反射率、黄度、整齐度、纤维强度为指标进行研究。结果表明:含水率、含杂率及压缩密度对棉籽破碎率影响显著(P<0.05),棉籽破碎率随压缩密度增大而增大,随含水率增加而降低;压缩密度仅对棉籽破碎率和反射率有显著影响(P<0.05);纤维长度随压缩密度、含水率增加而增加,随含杂率增加而减小;马克隆值随含杂率及含水率增加而增加,随压缩密度增加而减小;伸长率随含杂率增加而增加,随压缩密度及含水率增加而减小;反射率随压缩密度增大而增大,随含杂率增大而减小;黄度随含杂率增加而降低,随含水率增大而增大。Objective Machine-harvested seed cotton always undergoes compression and baling procedure to augment fiber packing density and diminish volume,thereby enhancing the efficiency of cotton transportation and storage.However,determining an optimal range for compression parameters,then ensuring minimal damage to the cottonseed and maximal preservation of cotton fiber quality,holds significant importance for cotton production.Therefore,it is imperative to investigate the morphology of the compressed cottonseed and the cotton fiber quality.Method To determine the primary and secondary relationship and the influence law of the compression parameters on the seed cotton quality,this study took the moisture content,trash content and compression density as the factors,and the cotton seed crushing rate,fiber length,micronaire value,elongation,reflectance(Rd),yellowness(+b),uniformity,and fiber strength as the indexes.Machine-harvested seed cotton was obtained through the cotton picking performance test,the cotton was compressed through the compression equipment,and the compressed cottonseeds and cotton fibers were obtained through ginning.The compressed cottonseed was chemically defluffed and dried to obtain the polished cottonseed,which was observed and screened with a microscope to obtain the cottonseed crushing rate;the compressed cotton fiber was sent to the testing laboratory to obtain the cotton fiber quality test results.Results The results of variance analysis indicate that the order of the affecting factors of the crushing rate of cottonseed after compression is compression density,moisture content,and trash content.The order for fiber length is trash content,moisture content,and compression density.The order for micronaire value is moisture content,trash content,and compression density.The order for the elongation was moisture content,trash content,and compression density.The order for reflectivity was moisture content,trash content,and compression density.The order for yellowness was trash content,moisture content,
