1984年金县友谊乡兴民科技队用塑料薄膜日光温室(不加温)搞番茄越冬生产试验获得成功。试验面积3分地,从当年11月22日开始采收,到翌年2月16日结束,折亩产番茄8,667斤,一茬亩产值6,933元。该项技术,经济、社会效益大,现介绍如下: 一、选地与温室结构选择向阳背风的梯形田。使温室北墙处于梯田埂下以利保温。若是平地,温室后墙外必须培土一米厚以上,并夹风障。温室后墙高1.3米,温室内支撑上盖的立柱高1.8米。温室后坡上盖用水泥预制板、石板或木板等均可,上面覆土0.3米厚。温室跨度4.5米,长短因地制宜。温室前拱用直径12毫米钢筋或能弯屈的竹竿,每隔0.6米插一根,东西用5根8号铁丝拉紧。二、品种、育苗与定植北京早红品种果实红色、耐低温、早熟,适宜温室栽培。8月10日育苗,9月中下旬定植,行株距0.5米×0.3米。亩施 1984 Jinxian Friendship Township Hing Man technology team with plastic film solar greenhouse (not warm) to engage in tomato overwintering production test success. Test area of ​​3 points, from November 22 that year began to harvest, to the end of February 16 the following year, fold yield 8,667 pounds of tomatoes, a crop of 6,933 yuan per mu. The technical, economic and social benefits are as follows: First, the choice of greenhouse structure and the choice of the sunny leap ladder field. So that the north wall of the greenhouse under the terrace to facilitate insulation. If the ground, the greenhouse wall must be more than one meter thick earth, and wind barriers. 1.3 meters high in the greenhouse after the wall, the greenhouse roof support post 1.8 meters high. Greenhouses slope covered with cement prefabricated panels, slate or wood can be, covered above 0.3 m thick. Greenhouse span 4.5 meters, length and length of the local conditions. Before the greenhouse with a diameter of 12 mm steel or bamboo can flexion, every 0.6 meters to plug one, something with five 8 wire tensioning. Second, the variety, nursery and colonization Beijing early red varieties of fruit red, low temperature, precocious, suitable for greenhouse cultivation. August 10 nursery, planting in late September, line spacing 0.5 m × 0.3 m. Mushi
