摘　　要：本试验通过对4年生平欧杂种榛喷施防冻剂,研究不同类型及不同浓度防冻剂对其抽梢情况的影响。结果表明,喷施2次防冻剂平欧杂种榛的抽梢比例低于喷施1次防冻剂。喷施3种不同的防冻剂都可以有效降低平欧杂种榛的抽梢程度,其中,平均抽梢枝粗由低到高排序为聚乙烯醇<液态膜<ABA,平均抽梢长度由低到高排序为液态膜<聚乙烯醇<ABA,平均抽梢比例由低到高排序为ABA<聚乙烯醇<液态膜。为降低平欧杂种榛的平均抽梢枝粗和平均抽梢长度,宜喷施20%的聚乙烯醇;为降低其平均抽梢比例,宜喷施10%的聚乙烯醇、20%的液态膜或4 000倍液的ABA。Through spraying antifreeze on 4-year-old hybrid hazelnuts,the effects of different types and concentrations of antifreeze on its sprouting situation were studied.The results showed that the sprouting ratio of hybrid hazelnuts sprayed with antifreeze twice was lower than that sprayed with antifreeze once.Spraying 3 different antifreeze agents could effectively reduce the sprouting degree of hybrid hazelnuts.Among them,the average sprouting branch thickness was ranked from low to high as polyvinyl alcohol<liquid film<ABA.The average sprouting branch length was ranked from low to high as liquid film<polyvinyl alcohol<ABA.The average sprouting ratio was ranked from low to high as ABA<polyvinyl alcohol<liquid film.To reduce the average sprouting branch thickness and length of hybrid hazelnuts,it was advisable to spray polyvinyl alcohol with a concentration of 20%.To reduce its average sprouting ratio,it was advisable to spray 10% polyvinyl alcohol,20% liquid film or 4 000 times liquid of ABA.
