In order to achieve the crop rotation of the protection land,solve the continuous crop-ping obstacles of vegetable production in the greenhouse,repair soil effectively and utilize fertil-ity fully,we have planted vegetable soybean in spring and aquatic vegetables in summer in plas-tic greenhouse.This method has significantly improved per unit area production and the effi-ciency.The net benefit of planting beans is 82 996.4 yuan·hm-2 ,while that of vegetable soy-bean-cress rotation pattern is 145 680.6 yuan·hm-2 in the greenhouse.The net benefit of the latter is 62 684.2 yuan·hm-2 higher than that of the former.It not only increases the efficiency, but also improves the utilization of land.
