摘要
基于棉田可持续发展的思想,研究了液体地膜覆盖对棉花产量与土壤物理性状的影响。结果表明,适量液体地膜(112.5kg/hm2)覆盖棉花增产显著,平均增产皮棉21.7%。液体地膜覆盖棉田提高土壤温度和含水量,降低土壤容重。表明液体地膜覆盖棉田对土壤环境无不良影响,利用液体地膜覆盖棉田是一项可行的技术。
Based on the theory of sustainable development of cotton field, the effects of liquid film mulching on cotton yield and soil physical properties were studied. The results indicated that application of reasonable amount of liquid film (112.5 kg/hm2) mulching averagely increased lint yield by 21.7%. Covering with liquid film mulching raised soil temperature and moisture, decreased soil bulk density, and had no adverse impacts on the soil environment. Therefore, it is a feasible technique to utilize the liquid mulching film in cotton field.
