Abstract：Comparison on dormancy characteristics of 7 different Chinese chive varieties was carried out.The results indicated：the‘pingjiu No.5’，‘pingjiu No.6’，and‘791’never fell dormancy in winter.Their heart leaf does not wither in winter open field（5 days）under mean temperature of 2.5 ℃，but the basic growth stops.The‘pingke No.2’，‘pingjiu No.3’，‘pingketaijiu’，and‘chunzaohonggen’are all dormancy varieties.During winter open field period，the whole ground leaf blade withers when the mean temperature is 0.7-10.5 ℃.Their dormant periods are 62，77，51，86 days，respectively.When the mean temperature inside of the small plastic shed is between 6.0-15.5 ℃，the dormancy period of 4 varieties were shortened to 31，25，23，32 days，respectively.The nondormancy variety in the small plastic shed，can be harvested two stubbles till February 28，the dormancy varieties is only once.The former can increase production by 77.61 %-164.22 % than the latter.The dormancy variety in winter protected cultivation must be covered when the dormant period is soon finished so as to display its productivity.The non-dormancy variety is usually better than the dormancy variety in early spring open field.
