为了解2种防冻液的使用效果，测定不同浓度防冻液处理的‘胎里红’枣树枝条分别在-16、-21、-26℃的低温条件下处理12 h的电解质渗出率变化情况。结果表明，郑州标典化工有限公司生产的防冻液处理的枝条在-21℃、-26℃时电解质渗出率均小于50%，而对照则大于50%，说明该防冻液具有一定的防冻效果，能使处理过的‘胎里红’枣枝条比没处理的枝条所耐受的临界低温降低4~5℃；而自制防冻液处理的枝条电解质渗出率和对照之间无明显差别，说明其起不到防冻效果。

In order to research the effects of two kinds of antifreeze, the electrolyte leakage rate changes of‘Tailihong’jujube branches were studied under treatments at-16℃,-21℃and-26℃for 12 h with different concentration of antifreeze. The results showed that the electrolyte leakage rate of the branches at-21℃and-26℃was lower than 50%with antifreeze made by Zhengzhou Biaodian Chemical Co.,Ltd, while the rate of control was bigger than 50%. The research results proved that this antifreeze product of Zhengzhou Biaodian Chemical Co.,Ltd possessed some antifreezing effects and could make the tolerant critical temperature 4℃to 5℃lower than control for‘Tailihong’jujube branches. However, there were no significant differences between self-made antifreeze and control which revealed self-made antifreeze with no antifreezing effect on‘Tailihong’ jujube branches under these experiment conditions.
