不同保温材料对库尔勒香梨树体保温效果的影响

目的]研究不同材料对库尔勒香梨树体保温效果的影响。方法]在果树越冬前,利用不同材料采用不同方式对树体进行包裹,将温湿度记录仪放置其中记录树体温度及湿度,分析不同处理下温度及湿度曲线的变化,筛选出库尔勒香梨树体保温最佳工艺。结果]不同材料之间,以铝箔+15 mm海绵对树体的保温效果最好,其次为发泡材料;铝箔和不同厚度海绵材料组合之间,以铝箔+20 mm海绵材料的保温效果最好,但考虑到经济实用性,选择铝箔+15 mm海绵材料为宜。结论]该研究可为果树越冬技术提供理论依据。

Effect of Different Materials on the Korla Fragrant Pear Insulation

Objective] The aim was to study effects of different materials on the Korla fragrant pear insulation. Method] Using different ma-terials and several ways to package tree, in which placing temperature and humidity recorder before the winter, the change of temperature and humidity curve in different treatments were analyzed, the optimal technique for Korla fragrant pear insulation was obtained. Result] Among different materials, aluminum foil +15 mm sponge had the best heat preservation effect for tree body and foam material took the second place; Aluminum foil +20 mm sponge material had the best heat preservation effect between the aluminum foil and different thickness of the sponge material combination, considering the economic practicality, choosing aluminum foil package material +15 mm thickness was opti-mal. Conclusion] The study can provide theoretical basis for overwintering technique of fruit tree.
