一、建适宜大棚。温室、大棚面积越大,缓冲性能及保温效果也越好,但棚越大,建设难度也大,成本也高。一般中棚以300～400平方米为佳。二、增施暖性肥。利用晴天,用马粪、米糠、稻草、树叶等酿热物中的微生物分解生温,提高地温。三、增强透光性。采用高透光无滴膜,及时清扫蔬菜大棚薄膜上的灰尘、污物和积雪等,可增强光照提高棚温。四、草帘上覆膜。
First, build appropriate greenhouse. Greenhouses, the larger the area of the greenhouse, the better the buffer performance and insulation effect, but the larger the shed, the more difficult the construction, the higher the cost. General shed 300 to 400 square meters better. Second, increase warm fertilizer. Use of sunny days, with horse manure, rice bran, straw, leaves and other microbes in the heat decomposition of temperature, increase ground temperature. Third, enhance translucency. Use of high light transmission drip film, timely cleaning of vegetable film greenhouse dust, dirt and snow, etc., can enhance the light to increase shed temperature. Fourth, straw curtain coating.
