摘要
对比冬季埋土与不埋土葡萄枝条水分含量变化表明:葡萄枝条冬季对低温的适应和自我锻炼过程需要相当长的时间;不埋土与埋土相比,冬季葡萄1 a生枝条水分含量变化的总体趋势是一致的,即自由水含量降低,而束缚水含量升高,只是变化幅度比埋土防寒的要大一些,表明,露地越冬的葡萄枝条能更快地适应外界环境的变化。北京地区,早春季节是葡萄1 a生枝条水分散失的主要时期。
The change of water content between buried and unburied annual branch of grapes in winter showed that： 1. the branch adapt to the low temperature and change its water content or sorts during a long time; 2. the trend that free-water content reduce and restrained water content increase in annual branch during winter between buried and unburied grapevines was coincident, but the change extent was wider in unburied grapevines. 3. the time of water loss in grape annual branch was at early spring in Beijing areas.
