目前,国内外对有色地膜的研究日益增多,地面覆盖蔬菜栽培的增产效果已基本肯定,但对它的机理还在探讨。地膜颜色不同,对土壤及蔬菜作物生长发育的影响也不同。1983～1985年,我们进行了有色地膜覆盖春季叶菜类、夏季果菜类的试验研究。试验旨在通过对有色地膜覆盖条件下的蔬菜生态环境特点的研究,了解各种膜对蔬菜生长发育、品质、产量影响,寻求适合内蒙古地区的春夏蔬菜栽培的有色地膜。
At present, the research on non-ferrous film at home and abroad is increasing day by day. The yield-increasing effect of ground-covered vegetable cultivation has been basically affirmed, but its mechanism is still under discussion. Different color film, the impact of soil and vegetable crops growth and development are also different. From 1983 to 1985, we carried out the experimental research on the covering of spring leaf vegetables and the fruits and vegetables in spring. The purpose of this experiment is to study the characteristics of vegetable ecological environment under the condition of colored mulching film to understand the influence of various kinds of film on the growth, quality and yield of vegetables and to seek the colored mulch film suitable for spring and summer vegetable cultivation in Inner Mongolia.
