为了解释越冬期不同冻害防治措施对树干形成层温度和融冻交替的影响,通过不同颜色和不同材料覆盖处理后,利用热电偶传感探头监测树干形成层温度的变化。结果表明,不同颜色处理和不同材料覆盖措施对树干形成层温度变化和融冻交替有明显的影响,树干颜色处理融冻交替大小顺序为:刮树皮>涂黑>对照(CK)>涂白;覆盖处理融冻交替大小顺序为:对照>麻绳>反光膜>绒毡片>稻草;覆盖处理形成层温度日较差均低于颜色处理,涂白形成层温度日较差比稻草和绒毡片处理平均高3~5℃。树干融冻交替和冻害防治效果最好的防治措施是涂白、稻草和绒毡片覆盖处理。
In order to explain the influence of different frost damage prevention and control measures during overwintering on the trunk formation temperature and the freeze thaw alternation, the changes of trunk formation temperature were monitored by thermocouple sensing probes after covering with different colors and different materials. The results showed that different color treatments and different material covering measures had significant effects on the temperature change and thawing alternation of tree trunk formation layer. The order of the tree trunk color freeze-thawing alternation was as follows: scratch bark> black> CK> The order of thawing and thawing alternation was as follows: control> hemp rope> reflective film> tapestry> straw; temperature difference of coating formation layer was lower than that of color treatment, and temperature of coating formation layer was worse than that of straw and cashmere Mat processing average high 3 ~ 5 ℃. Tree trunks alternate freeze-thaw control and prevention and treatment of the best prevention and control measures are coated with white, straw and tape mat cover treatment.
