摘要:
应用热脉冲技术，对内蒙古自治区乌兰察布盟中旗的主要造林树种樟子松的液流变化进行了1年的观测，对液流量的日变化、各位点液流及全年液流量的变化进行了深入地研究。结果表明：樟子松在正常生长状态下，树干液流量日进程呈现单峰型曲线，全天总液流量为25.61L，全年总液流量为3423.35L；樟子松木质部不同部位输水能力差异较大，液流速度最大的位点位于形成层外5～10mm处；樟子松单位边材面积日累计液流量Qa为1.56m3/m2左右，整个过程呈现"S"
Abstract:
Pinus sylvestris var. mongolica, which is a major species for afforestation in Central Chahaer banner, Wulanchabu League, Inner Mongolia, had been investigated by employed heat impulse technique to analyze daily change, yearly fluctuation, and different points capacity of stem-sap flow.Results showed that daily change curve of the stem-sap flow was single peak and daily capacity of the stem-sap flow was 25.61 L and yearly capacity was 3 423.35 L.For xylem, transferring water ability was obviously differentia in different positions, and liquid flow reached maximum at the xylem outside 5～10 cm.Daily accumulation capacity of sapwood liquid flow was 1.56m3/m2, entire process of daily liquid flow presented S-form in temporal scale.
