不同韭菜品种的休眠特性及其应用研究初报

Preliminary studies on dormancy traits of different Chinese chive varieties and their applications

通过大量的田间和室内试验 ,研究了不同处理形式对不同类型韭菜品种的萌发及生长特性的影响 ,结果表明 :参试的韭菜品种可分为两大类型 ,即无休眠类型和有休眠类型 ;在冬季保护地韭菜栽培中 ,在河南地区 ,选用有休眠类型的韭菜品种 ,合适的覆盖时间一般为地上部干枯完全回秧以后 ,即 12月中下旬 ;选用无休眠类型的韭菜品种 ,可不回秧覆盖进行连续生产 ,也可回秧后再覆盖生产 .

Traits of germination and growth of different Chinese chive varieties were investigated under different treatments through field and indoor experiments.Results reveal that the Chinese chive varieties involved in the experiments are divided into two types:non dormancy type and dormancy type.The optimal covering period of dormancy type of Chinese chive in Henan,generally,is after wilting about in the mid later December.As for non dormancy it is advisable to successively produce in protected field at any time according to marketplace,regardless of wilting.
