sap flow density

基本解釋

Effective photosynthetic radiation and deficient vapor pressure were the dominant environmental variables affecting the diurnal variation of sap flow density on sunny days.
影響樹干液流密度日變化的主導(dǎo)因子為光合有效輻射和水汽壓虧缺，二者對(duì)主導(dǎo)因子敏感度相當(dāng)。
Sap flow density is low and anomalistic, even formed multi-peak curves which has not obvious peak value during rainy days, sap flux density during night is larger than its in sunny days.
各樹種陰雨天液流密度變化曲線均不規(guī)則且液流密度值較小，甚至出現(xiàn)多峰曲線，但峰值并不明顯。

樹干液流密度
Each tree sap flow density had significant seasonal change.
各樹種樹干液流密度在生長(zhǎng)季有明顯的變化。
