摘　　要：以8年生莲雾为试材,研究不同覆盖方式对莲雾的防寒效果并进行评价,通过比较越冬防寒期间的莲雾落叶率和温度变化,翌年莲雾的物候期、产量和品质,分析比较不同覆盖方式对莲雾的防寒效果.结果表明,树冠覆盖处理莲雾的落叶率明显低于覆草、覆膜以及对照处理,使用树冠覆盖的莲雾在第二年物候期比其他处理早20~30天,产量、单果重、可溶性固形物含量及经济利润均高于覆草、覆膜和对照处理.综合分析树冠覆盖可以更有效地降低低温对莲雾生产的风险,在广西有非常大的推广潜力和应用价值.In order to to study the effect of different coverage methods on the cold-proof effect of wax apple,eight-year-old wax apples were used astest materials.By comparing the defoliation rate and temperature change of wax apple during winter and cold-proof period,the phenological period,yield and quality in the second year,the coldproof effect of different coverage methods on wax apple was analyzed and compared.The results showed that the defoliation rate of the canopy covered wax apple was significantly lower than that of grass covering,mulching and control processing.The phenomenal period covered with the canopy was 20 to 30 days earlier than the other treatments in the second year.Besides,the crown cover treatment’s yield,single fruit weight,soluble solid content and economic profit were higher than that of grass covering,film mulching and control treatment.Therefore,comprehensive analysis of canopy cover can effectively reduce the risk of low temperature on lotus fog production,and has a very large promotion potential and application value in Guangxi.
