温州市蔬菜大棚生产从1986年市蔬菜所引进12套6×30m镀锌钢管大棚以来,得到了迅速发展。但大棚蔬菜栽培中也遇到了许多问题,如高、低温危害,高湿导致冻害、徒长及灰霉病旺发等,降低了大棚的效益。近几年来,我们在气象部门的配合下,对蔬菜大棚小气候效应进行了观测,研究与分析,并提出了相应的对策。1我市冬春季气候特点 我市地处浙江东南沿海,位于北纬27°05′40″～28°37′00″,东经119°37′00″～121° Since the introduction of 12 sets of 6 × 30m galvanized steel tube greenhouses from vegetable market in 1986 in Wenzhou, the production of vegetable greenhouses has been rapidly developed. However, greenhouse vegetable cultivation has also encountered many problems, such as high and low temperature hazards, high humidity caused frost damage, leggy and gray mold disease, etc., reducing the benefits of greenhouses. In recent years, with the cooperation of the meteorological department, we observed, studied and analyzed the microclimate effects of vegetable greenhouses and put forward corresponding countermeasures. 1 City winter and spring climate characteristics The city is located in the southeast coast of Zhejiang Province, located at latitude 27 ° 05’40 “~ 28 ° 37’00”, longitude 119 ° 37’00 "~ 121 °
