蒸散作用

棉田群体冠层特征对于研究棉花光合作用、蒸散作用等和创建棉花理想的高产株型模式非常重要。

The factor of cotton canopy is very important for researches on cotton photosynthesis and evapotranspiration and creation of cotton high yield plant type .

对降低密度减少蒸散的作用大小，作为调控措施的有效性，有效的密度调控范围等，还需严格的对比实验和理论研究。

More strict comparisons and theoretical researches are required for evaluating the ET-reduction effect by decreasing density , the availability of decreasing density as a measure of reducing ET , and for searching the effective range of density regulation .

净辐射对蒸散起决定作用，蒸散速率的变化趋势与净辐射变化基本一致，其日变化具有相同的峰型。

The net radiation plays critical role in plant evapotranspiration . The trend of net radiation change is similar to evapotranspiration rate ; the diurnal variation has the same peak type .
