一、扣棚时间一般在入冬前扣棚。也可根据上市期确定扣棚时间,即在上市期向前推40—50天为扣棚时间。二、温湿度管理小拱棚韭菜白天生长的适温为18—25℃,夜间温度为8—12℃,最低不能低于5℃,空气相对湿度控制在60—70%为宜。三、中耕覆盖与培土韭菜吸收水分和养分能力较差,而且根系分布较浅。扣棚化冻以及每次割完韭菜后,先搂去畦面枯叶与杂物,再用三齿耙在株间松土中耕
First, deduct the shed time generally before the winter deduction shed. Can also be based on the listing period to determine the deduction shed time, that push forward 40-50 days in the listing period for the deduction shed time. Second, the temperature and humidity management Small Shed leek growth temperature during the day is 18-25 ℃, night temperature is 8-12 ℃, the minimum can not be less than 5 ℃, air relative humidity control in 60-70% is appropriate. Third, cultivated land cover and cultivated leek to absorb water and nutrient capacity is poor, and the root system is shallow. Jianpeng frozen and cut each finish leeks, the first hug to face dead leaves and debris, and then use three-tooth rake in the tillage between cultivation
