Effects of Continued Mulching of Plastic Film with Different Thickness on Soil Physical Properties and Film Residues in Maize Field
为了探明不同厚度地膜对土壤物理性状及地膜残留量的影响,采用大田定位试验,连续4年对玉米田分别进行0.006 mm、0.008 mm(CK)、0.010 mm、0.012 mm厚地膜覆盖处理.结果表明:①0～40 cm土层,随着地膜厚度的增加,土壤紧实度和土壤容重降低.0.010 mm、0.012 mm处理土壤容重比0.008 mm(CK)分别降低了1.25％、2.43％,而0.006 mm处理比CK提高0.76％.②玉米播种至大喇叭口期,0.00…查看全部>>
To investigate the effects of different thickness plastic film mulching on soil physical properties and plastic film residues in soil,this paper carried out 4 continuouse years' studies by adopting a field trial.The results showed that:①soil compactness and soil bulk density decreased in 0～ 40 cm soil layer as the thickness of plastic film increased.The soil bulk density for treatments of 0.010 mm and 0.012 mm decreased by 1.25％ and 2.43％,respectively,while,…查看全部>>
