去年,金县友谊乡兴民科技队,利用塑料日光温室在冬季不加温的情况下进行番茄生产,收到了良好效果。从11月22日开始采收至翌年2月16日拉秧,折亩产番茄8,667斤,一茬亩产值6,933元。实践证明,这种栽培法具有节约能源、生产成本低、经济效益显著等优点。一、选地建温室.选择背风向阳的山坡梯田建温室,使温室北墙处于梯田埂下,以利保温。如果在平地建温室,后墙外必须培土1米厚以上、并夹风障。温室跨度4.5米,后墙高1.3米,温室支撑上盖的立柱高1.8米。温室前部用
Last year, Friendship Township, Jinxian Xingmin technology team, the use of plastic solar greenhouse in the winter without heating the case of tomato production, received good results. From November 22, harvesting began until February 16 of the following year for poplar seedlings, yielding 8,667 pounds of mu per mu and 6,933 yuan of mu per mu. Practice has proved that this cultivation method has the advantages of saving energy, low production costs, significant economic benefits. First, choose to build a greenhouse Select leeward hillside terraced greenhouse, so that the north wall of the greenhouse in the terraced rice fields to facilitate insulation. If the construction of greenhouses in the ground, the back wall must be earth more than 1 meter thick, and wind barriers. Greenhouse span 4.5 meters, 1.3 meters high after the back wall, greenhouse support cover 1.8 meters high column. The front of the greenhouse
