越橘品种北陆不同构件生物量生长季节动态变化

Study on the dynamic change of different components of the cultivar Northland of Vaccinium in growth season

利用生物量收割法对越橘品种北陆不同构件的生物量生长季节动态进行研究。结果表明,越橘地上部构件一年生茎、多年生茎和叶在生长季节中一直呈上升趋势,在生长季节末期略有下降;地下部构件根茎和根在生长季节初期呈下降趋势,8月开始上升直至生长季节末期;总生物量在9月达到最大值为410.1 g;每株生物量绝对增长速率最大值出现在9月为4.276 g.d-1,相对增长速率最大值出现在8月为0.020 g.g-.1d-1。

The dynamic change of different component biomass of the cultivar Northland of Vaccinium was studied in the growth season by the harvesting method. The results were as followings, their biomass of one-year stems, perennial stems and leaves had been increasing in the growth season and at the end of the growth season, it decreased slightly. Its biomass of the rhizome and root decreased in the early days of growth season and increased from August to the end of the growth season. The total biomass reached the maximum in September was 410.1 g. The maximum value of absolute biomass growth rate was 4.276 g. d-1 in September. The maximum value of relative biomass growth rate was 0.020 g.g-1.d-1 in August.
