地膜覆盖是甘蔗栽培技术中一项重大革新。蔗田盖地膜起到显著增(保)温、增肥(速效肥分)、保湿、保土和保持土壤疏松的作用,为水田甘蔗创造良好的人工生态环境。虽然水田土壤水分比较充足,但冬季气温低于13—15℃时,甘蔗仍然无法萌发生长。盖膜后,膜内温度迅速增加2～7℃,这样就能充分利用低温季节的阳光,促使甘蔗提早萌发,提高萌芽率,增强苗期群体结构,提早生长,延长生长期打下光合作用基
Film mulching is a major innovation in sugarcane cultivation. Sugar cane cover plastic film played a significant increase (Paul) temperature, fertilizer (quick-fat), moisturizing, soil conservation and to maintain the role of loose soil, sugar cane to create a good artificial ecological environment. Although paddy soil moisture is adequate, but the winter temperature is below 13-15 ℃, sugar cane is still unable to germinate and grow. After the membrane is covered, the temperature in the membrane rapidly increases by 2 ~ 7 ℃, so that sunlight in low temperature season can be fully utilized to promote the early germination of sugarcane, increase the germination rate, enhance the population structure at seedling stage, prematurely grow and lay the photosynthetic base
