曲阜市时庄镇自1996年以来,利用日光温室(冬暖大棚)栽培越冬茬菜豆,取得了可观的经济效益。经三年调查,平均666.7m~2(亩)产5000kg以上,产值1.4～1.6万元。现将主要经验介绍如下。一、选用高性能日光温室所用日光温室具有以下特点:墙体厚,后墙及山墙均达1m以上;棚体高,脊高达3.0m;后坡面仰角达45°,冬季光线能照射到后墙上:四层覆盖,由内向外依次是地膜、大棚膜、草苫、塑料膜。因此,大棚采光、增温、保温性能良好,冬季温室最低温度在13℃以上。二、选用优良品种选用生长势强,开花结荚期长,产量高,品质好,耐贮藏,好销售的品种“绿丰”。三、整地、施肥、起垄温室夏季休闲后,及时清除枯叶杂草,每666.7m~2施优质圈肥5000～8000kg或腐熟
Since 1996, the town of Quzuo, Qufu has used solar greenhouse (winter warm shed) to cultivate winter beans and gained considerable economic benefits. After three years of investigation, an average of 666.7m ~ 2 (mu) production of more than 5000kg, the output value of 1.4 to 16,000 yuan. The main experience is as follows. First, the choice of high-performance solar greenhouse greenhouse used has the following characteristics: thick walls, back walls and gables are more than 1m; shed high, ridge up to 3.0m; after the slope elevation of 45 °, the winter light to the rear wall On: four layers of coverage, followed by the film from the inside, green film, straw, plastic film. Therefore, the shed lighting, warming, good insulation properties, the minimum temperature in winter greenhouse above 13 ℃. Second, the selection of elite varieties of growing potential strong, long flowering pod, high yield, good quality, storage resistance, good sales varieties “Green abundance ”. Three, land preparation, fertilization, ridging greenhouses Summer leisure, the timely removal of dead weeds, every 666.7m ~ 2 high quality circle fertilizer 5000 ~ 8000kg or maturity
