Our self-designed plastic film energy-saving solar greenhouse, after several years of winter cultivation and meteorological observation, has the advantages of simple structure, without manual heating, low cost, high efficiency, indoor temperature, light can meet the high-grade fine vegetable growth Developmental requirements. In order to find out the types of vegetables with high output value in winter solar energy conservatory, different vegetable output tests were conducted. The results are as follows. I. Materials and methods 1. The types and varieties of cucumbers (varieties of Nongda No.14, Changchun sting, cucumber), celery (American celery), garlic seedlings (seaweed), leek (maranth leek), tomatoes ),chili. 2. Solar greenhouse structure and performance of the north-south south slope of the single-sided plastic film solar greenhouse, 24 meters long, 5 meters wide, an area of 120 square meters, nighttime film covered quilts or 5 layers of kraft paper was cold insulation. It is measured, mid-November ~ 3
