黑龙江省是我国甜菜生产的重要基地,甜菜又是我省主要经济作物之一。近几年甜菜种植面积已达450多万亩。 近两年,地膜覆盖栽培技术在我省已广泛应用。地膜覆盖蔬菜、西瓜等十多种作物,已收到显著的经济效益,但能否在甜菜种植上应用此项技术,国内外还都处于试验阶段。为了探讨甜菜地膜覆盖的可行性和经济效益,黑龙江省农机局农业机械化生产技术推广站,1984年把机械覆膜甜菜
Heilongjiang Province is an important base for producing beet in our country. Beet is one of the major cash crops in our province. In recent years, beet cultivation area has reached more than 450 million mu. The past two years, mulching cultivation techniques have been widely used in our province. Mulch covers more than ten kinds of crops such as vegetables and watermelons and has received significant economic benefits. However, whether this technology can be applied to beet cultivation is still at the experimental stage at home and abroad. In order to explore the feasibility of sugar beet mulching and economic benefits, Agricultural Machinery Bureau of Heilongjiang Agricultural Mechanization Production Technology Extension Station, in 1984 the mechanical coated beet
