摘　　要：为探讨小麦前后置双镇压播种机镇压对土壤条件和小麦生育性状的影响,以济麦22小麦为试验材料,开展了播种时双镇压处理试验。结果表明,播种时镇压处理较对照未镇压处理0~20 cm土层含水量增加4.47%,>20~40 cm土层含水量增加0.67%,>40~60 cm土层含水量增加1.62%;镇压后0~20 cm土壤容重增加12.00%,>20~40 cm土壤容重增加7.53%。小麦前后置双镇压播种机镇压可以促进小麦分蘖,单株次生根数增加1.8条(增幅64.29%),受冻枯叶率降低20%,有效穗数增加31.5万穗/hm^(2)(增幅6.27%),穗粒数增加1.1粒(增幅3.13%),产量提高1201.5 kg/hm^(2)(增幅14.15%)。In order to investigate the effect of pressing of dual pressure seeders placed in front and rear for wheat on soil conditions and wheat growth characters,the wheat Jimai 22 was used as experimental material to carry out a test on double pressing treatment when seeding.The results showed that compared with control layer(no pressing),the soil water content in layers of 0-20 cm,>40-60 cm and>20-40 cm in pressing treatment when seeding increased by 4.47%,0.67%and 1.62%,respectively.After pressing,the soil bulk density in layers of 0-20 cm and>20-40 cm increased by 12.00%and 7.53%,respectively.The pressing of dual pressure seeders placed in front and rear for wheat could effectively promote wheat tiller,the number of secondary roots per plant increased by 1.8(64.29%),the frozen dead leaf rate decreased by 20%,the effective panicle number increased by 315000 per hectare(6.27%),grain number per panicle increased by 1.1(3.13%),and wheat yield increased by 1201.5 kg/hm^(2)(14.15%).
