由于春季干旱,新栽栗树采用地膜覆盖法是提高成活率效果显著的技术措施。据试验,采用0.01mm白色透明聚乙烯簿膜覆盖,对发枝量、新梢长度、干周粗度和成活率有显著影响,覆膜的成活率为99.5%,不覆膜为91.5%。主要原因是:地膜覆盖可有效地防止土壤水分蒸发,土壤含水量提高47.4%,土
Due to spring drought, newly planted chestnut trees with plastic film mulching method is a significant technical measure to improve the survival rate. According to the experiment, it is covered with 0.01mm white transparent polyethylene film film, which has a significant effect on the amount of shoots, the length of new shoots, the dry circumference and the survival rate. The survival rate of the coated membrane is 99.5% and the non-coated membrane is 91.5%. The main reason is that the mulching can effectively prevent the evaporation of soil moisture, and the soil water content increases by 47.4%
