冬季日照时间短,太阳光照强度弱,阴、雾、雪天气多,所以日光温室内的管理应以增温、保温、补光为主。技术措施如下:1、基础设施:栽培越冬茬黄瓜的温室,要求温室墙体厚度在100厘米以上,后坡垂直投影距离在100厘米以上,后坡上玉米秸压实后的厚度要达到33厘米,玉米秸最好用塑料包裹,玉米秸上的土层厚度不得低于35厘米,温室内地面比外界地面低60厘米(半地下),采用聚氯乙烯塑料膜,双层草苫,要求草苫干重50 Winter sunshine time is short, the sun’s light intensity is weak, cloudy, fog, snow and more, so the management of solar greenhouse should be warming, insulation, fill light-based. The technical measures are as follows: 1. Infrastructure: Greenhouses for planting winter cucumbers require that the thickness of the greenhouse walls be more than 100 centimeters, the vertical projection distance of the back slopes should be more than 100 centimeters, and the thickness of the post-slope corn stalks should be 33 centimeters , The best corn stalks wrapped in plastic, corn stalks on the soil thickness of not less than 35 cm, the ground in the greenhouse than the ground outside 60 cm (semi-underground), the use of PVC plastic film,苫 dry weight 50
