摘 要:为探讨甘薯地膜覆盖栽培的增产效应,在河南省商丘市农林科学院试验田进行了甘薯栽植前后覆盖透明膜或黑膜处理对土壤含水量、容重、地温及甘薯产量影响的研究。结果表明,早春甘薯地膜覆盖栽培,以栽后覆透明膜或栽前覆黑膜增产效果相对较好。To explore the yield-increasing effects of sweet potato with film mulching cultivation, the influence of Sweet potato before and after planted with transparent film and black film mulching on soil water content, soil bulk density, earth temperature and sweet potato yield were tested in experimental field of Shangqiu Academy of Agriculture & Forestry Sciences. The field test resuits show that the yield-increasing effects of black film mulching before planting and transparent film mulching after planting in the early spring are fairly good.
