近年来,北方地区日光温室葡萄反季节栽培已成农业的支柱产业,经济效益显著。本试验设在北京林果所果树新品种示范基地,北京市丰台区王佐乡青龙湖畔,总面积为40hm2,其中日光温室葡萄栽面积为5280m2,主栽品种香妃占3360m2,其次是87-1（玫瑰香型品系）,无核早红,京秀等。经过两年的栽培示范,已初见成效,1999年4月15日定植,2000年6月16日采收,折合666.7m2产量,香妃551.7kg,87—1（玫瑰香型品系）536.5kg,比露地提早采收56天。达到预期优质丰产的目的。1 日光温室的基本结构和立地条件 北京地区冬季较寒冷,日光温室用加气混泥土砖砌墙后墙中间设10cm厚度的塑料保温材料,墙总厚度为70cm,东西墙厚度为100cm后墙高250cm,温室脊高为3.2m。采光面呈拱形。后屋面角为25°-35°范围,棚屋面用6cm钢管拱形框架,框架间隔1m。上覆大棚无滴膜,顶覆双层无纺布,厚度5cm。用电
In recent years, the northern region of greenhouse greenhouse season cultivation has become a pillar industry of agriculture, significant economic benefits. The experiment is based on the fruit tree new variety demonstration base of Beijing fruit and fruit tree, Qinglong Lake, Wangzuo Township, Fengtai District, Beijing. The total area is 40hm2, of which the area of viticulture is 5280m2 in greenhouse and 3360m2 in main cultivars, followed by 87-1 (Rose flavor-type strains), nuclear-free early red, Beijing show and so on. After two years of cultivation and demonstration, it has achieved initial success. It was planted on April 15, 1999 and harvested on June 16, 2000, yielding 666.7m2 yield, with 551.7kg of fragrant yellow and 536.5kg of 87-1 (rose-scented strain) , 56 days earlier than the open field harvest. Achieve the purpose of high quality and yield. A solar greenhouse basic structure and site conditions Winter in Beijing is colder, solar greenhouse aerated concrete brick wall with a 10cm thickness of the middle wall of the plastic insulation material, the total thickness of the wall 70cm, wall thickness of 100cm wall thickness 250cm, greenhouse ridge height 3.2m. Light surface was arched. After the roof angle of 25 ° -35 ° range, shed roof with 6cm steel arch frame, frame interval 1m. Over the shed no drip film, top double-coated non-woven fabric, the thickness of 5cm. Electricity
