对 7个韭菜品种在不同覆盖时期和栽培形式下的休眠特性进行了比较 ,结果表明 ,参试的韭菜品种可分为两大类型 :791、平韭 4号、赛松、杭州雪韭、汉中冬韭为无休眠类型 ;平韭 2号、山东独根红为休眠类型。在河南地区 ,冬季保护地韭菜栽培若选用休眠类型品种 ,一般在 12月中下旬完全返青后进行覆盖 ;若选用无休眠类型的韭菜品种 ,可以随时进行覆盖生产 ,只要温度适宜即可萌发生长
The dormancy characteristics of seven Chinese leek cultivars under different coverage periods and cultivated forms were compared. The results showed that the Chinese leek cultivars could be divided into two types: 791, Pingchu No.4, Saisong, Hangzhou Xuechu, Hanzhong Winter leek no sleep type; flat leek 2, Shandong single root red sleep type. In Henan Province, if the dormancy type is selected for the leek cultivation in the winter protection area, it is generally covered in the middle and late December when it is completely rejuvenated; if the chives species without dormancy is selected, covering production can be carried out at any time, and the germination and growth can be carried out whenever the temperature is suitable
