众所周知,地膜覆盖栽培能提高土温,防止土壤水分蒸发和肥料流失,对春植蔗具有促进早苗、早分蘖、早伸长和成茎,提高出苗率、分蘖率,增加有效茎数,提高甘蔗产量和蔗糖分的作用。因此,近年来,地膜覆盖栽培已引起我国广大蔗区的重视,覆盖面积越来越大,地膜需要量急剧增加,出现供不应求状况。0.006毫米低压高密度聚乙
As we all know, plastic film mulching can increase soil temperature, to prevent the evaporation of soil moisture and fertilizer loss on the spring plant sugarcane to promote early seedlings, early tillering, early elongation and stems, increase the emergence rate, tillering rate, increase the effective stem number and improve sugarcane The role of yield and sucrose fraction. Therefore, in recent years, plastic film mulching cultivation has attracted the attention of the majority of sugarcane planting areas in our country, covering an increasingly large area. The demand for mulching film increased sharply and there was a shortage in demand. 0.006 mm low-pressure high-density polyethylene
