地膜盖蔗是80年代初应用于甘蔗生产的一项新技术。它创造了一个保温、保水、保肥、透光性好、土壤松散的甘蔗生长环境,有利甘蔗早生快发,培育壮苗,增加有效茎数,为甘蔗高产打下良好的基础。1990年全国地膜盖蔗60万亩,每亩增产甘蔗0.5～1吨,增加糖分0.3～1.2度,节省种苗150～200公斤,扣除成本20～30元,每亩纯收入增加60～200元。另外,地膜盖蔗对促进甘蔗提早成熟,改善品质,解决霜冻蔗区的越冬和春播早植等方面有良好的效果
Mulch is a new technique applied to sugar cane production in the early 1980s. It creates a sugar cane growth environment with good thermal insulation, water retention, fertility, good light transmission and loose soil. It is good for quick growth of sugarcane early in life, cultivating strong seedlings, increasing effective stalks and laying a good foundation for high yield of sugarcane. In 1990, the country covered 60 million mu of plastic mulching cane and 0.5-1 ton of sugarcane per acre. It increased the sugar content by 0.3-1.2 degrees and saved 150-200 kilograms of seedlings. After deducting the cost of 20-30 yuan, the net income per mu increased by 60-200 yuan . In addition, the film covered sugar cane to promote early maturity, improve quality, to solve the frost cane area overwintering and early spring planting has good results
