摘要/Abstract

摘要： 针对黄土高原地区受干旱的制约导致侧柏幼林存活率不高、生长缓慢的现状,研究了铺设生态垫对侧柏幼林地土壤水分、生长速度、光合效率等的影响。结果表明:短期内铺设生态垫对土壤水分影响不大,但可显著促进林木生长,使侧柏根系提早萌动,显著提高林木叶片净光合速率(Pn)和蒸腾速率(Tr)。

关键词: 黄土高原, 生态垫, 侧柏幼林, 光合速率

Abstract: In the light of the low survivial rate and slow growth of young Chinese arborvitae trees caused by drought in the loess plateau, the article studied the effects on soil moisture holding capacity and growth rate and photosynthetic rate after the ecomat was placed under the young arborvitae trees.The results showed that the ecomat didn't affect the soil moissture holding capacity,but made the young arborvitae tree grow faster and improved the Pn and Tr of the arborvitae tree leaves.

Key words: loess plateau, ecomat, the young Chinese arborvitae, photosynthetic rate
