卢龙县城关镇郑庄村利用日光温室生产黄瓜,一般亩产5500公斤,产值6000元左右,目前已发展成河北省无公害黄瓜生产基地并进行了商标注册。现将日光温室黄瓜无公害高产高效栽培关键技术介绍如下:一、温室环境温室采用半地下式,即温室地面比外界低20—30厘米,这样既保温又抗风。温室的两侧围墙和后墙厚度应为当地最大冻土层的2倍以上,后坡厚度要超过当地最大冻土层的2/3。前屋面双层膜覆盖。外再盖一层浮膜(用旧棚膜)可提高
Zhenglong Village, Chengguan Town, Lulong County, uses cucumbers in the solar greenhouse to produce 5,500 kilograms of mu per mu, with a production value of 6,000 yuan. At present, it has developed into a pollution-free cucumber production base in Hebei Province and conducted trademark registration. Now greenhouse solar greenhouse cucumber efficient high-yielding cultivation of key technologies are as follows: First, the greenhouse greenhouse with semi-underground environment, that is, the greenhouse floor 20-30 cm lower than the outside world, so both insulation and wind resistance. The thickness of the wall and back wall on both sides of the greenhouse should be more than twice the maximum permafrost in the area and the thickness of the back slope should exceed 2/3 of the maximum permafrost in the area. Front roof double membrane cover. Cover with a layer of floating film (with the old film) can be improved
