1.搭配适宜品种 适宜一膜三用栽培的韭菜品种有791、寒青、汉中等。寒青耐低温,生长力强,0℃时停止生长,几乎没有休眠期,不经低温锻炼仍能连续生长,适宜作为一膜三用中的晚秋和初冬保护地栽培品种。汉中冬韭必须在-7—-5℃的低温下,经过7—10天的锻炼后才能在适宜温度下恢复生长。所以,它适宜在一膜三用中作为深冬保护地栽培。791韭菜不需休眠期,适宜在16—25℃条件下生长,可作为一膜三用中最先扣棚的栽培品种。
1. With the appropriate varieties suitable for a three-culture leek cultivars 791, chilling, Hanzhong and so on. Cold hardy low temperature, strong growth, stop growing at 0 ℃, almost no dormancy, can continue to grow without low temperature exercise, suitable as a membrane in the late autumn and early winter protected cultivars. Han Chinese winter mustard at -7--5 ℃ low temperature, after 7-10 days of exercise to resume growth at the appropriate temperature. Therefore, it is suitable for cultivation in a three-purpose film as a winter protection. 791 leek without dormancy, suitable for growth in the conditions of 16-25 ℃, can be used as a membrane in the first three kinds of cultivars with cloak.
