利用酿热物增温 用马粪、米糠、稻草、树叶等酿热物中的微生物分解生温,提高地热。 设电热温床 在蔬菜大棚内设置电热温床,可以保持土壤一定温度。 加“围裙”在棚内侧四周加一道1m多高的薄膜,或用草帘围住,也可以提高棚内温度。 多层覆盖 在大棚中加设二层膜。就是说在大棚 The use of stuffed with heating material with horse manure, rice bran, straw, leaves and other microbes in the heat decomposition of raw materials to increase temperature, heat. Set hot electric hotbed in the greenhouse to set electric hotbed, you can maintain a certain temperature of the soil. Add “apron” around the shed plus a 1m high around the film, or surrounded by straw curtain, can also raise shed temperature. Multi-layer coverage in the shed plus two layers of film. That is in the greenhouse
