为提高冬季菜地的利用率,改变传统蔬菜与食用菌单一生产结构,我所从1983年冬季开始进行平菇、蔬菜轮作试验,取得了较好效果。1984年冬季又进行了重复性试验,1985年秋末冬初在济宁地区进行了示范推广冬闲菜地50亩,经济效益显著(见表)。现将试验情况简报如下。 In order to improve the utilization rate of winter vegetable fields and change the single production structure of traditional vegetables and edible mushrooms, we started the test of mushroom cultivation and vegetable rotation in the winter of 1983 and achieved good results. In the winter of 1984, repeated tests were conducted. In late autumn and early winter of 1985, a total area of ​​50 mu was used for demonstration and promotion of winter vegetable fields in Jining. The economic benefits were remarkable (see table). Now the test briefings are as follows.
