研究了修剪、铺草、覆膜、喷灌防冻剂等6项技术措施对山地茶园茶树的抗寒性影响及SOD、POD酶活性与受冻率之间的关系,结果表明:①各处理随着受冻率的增加,在一定范围内SOD酶活性也相应增加,这与茶树自身的修复功能有关;②对于山地茶园,受风冻影响,直接应用于茶树树冠的技术措施要比应用于环境及土壤的技术措施效果好.6种处理效果为:覆膜>铺草>对照>未修剪>灌根>喷冠;③秋天进行适当的修剪,对降低茶树冻害有利.

Six kinds of technical measures (pruning, covering couch grass, mulching plastic film, sprinkling irri-gation antifreeze etc.) were used to mountain tea plantations to improve the capacity of frost resistance and study the relationship between the enzyme activity of SOD, POD and freezing rates. The results showed that: (1) with freezing rates increase, the enzyme activity of SOD also increases accordingly, in a certain range to various technical measures. This is because tea plants have the self-repairing ability; (2) to mountain tea plantations; the technical measures used directly to crown of tea plant have better effect than used to environment and soil because of wind-chill effect. The result of six kinds of the technical measures is: mulching plastic film > cover-ing couch grass > CK> no pruning>irrigating roots> spraying crown; (3) It's beneficial to tea plant to reduce freezing injury with suitable pruning in autumn.
