近年来,随着山西能源重化工基地建设步伐的加快,太原市郊蔬菜生产迅速发展,塑料大棚已达1200余亩,温室达40000间,今后还将逐年发展。为了提高蔬菜生产水平,我们从1984年开始进行了沼气在塑料大棚蔬菜生产中的综合利用试验,取得了初步的效果。一、利用沼气在初冬时为大棚加温,延长蔬菜生长期,提高产量试验 1984年11月7日到12月5日,我们对大 In recent years, with the accelerating pace of construction of Shanxi Energy Heavy Chemical Industry Base, the vegetable production in the suburbs of Taiyuan has developed rapidly. The plastic greenhouse has reached more than 1,200 acres and the greenhouse has reached 40,000. It will also develop year by year. In order to raise the level of vegetable production, we started the comprehensive utilization test of biogas in vegetable production in plastic greenhouses since 1984, and achieved initial results. First, the use of biogas in the winter for the greenhouse to warm, to extend the vegetable growth period, increase production test November 7, 1984 to December 5, we are big
