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)。 In view of the fact that the drought resistance of Platycladus orientalis young forest is not high and the growth is slow due to drought control in Loess Plateau, the effects of laying ecological mat on soil moisture, growth rate and photosynthetic efficiency of Platycladus orientalis young plantation were studied. The results showed that the laying of ecological pad in short term had little effect on soil moisture but could significantly promote the growth of forest trees and premature germination of the arborvitae root system and significantly increase the net photosynthetic rate (Pn) and transpiration rate (Tr) of forest trees.
