留萌措施对米老排伐桩萌芽条生长与生物量的影响
Effects of Sprout Reserving Method on the Sprout Growth and Biomass Accumulation of Mytilaria laosensis
摘要
Abstract
In this paper,effects of reserved sprouting number of Mytilaria laosensis on the seedlings growth and biomass accumulation were investigated with 120 stumps in Daqingshan forest region.Four treatments were applied:1,2,and 3 sprouts per stump were reserved,no removal of sprouts was served as the control.Along with the increase of the number of reserved sprouts,the mean height and diameter of the sprouts decreased,1 sprout per stump demonstrated higher growth potential.For different parts of a sprout,the biomass ranked as trunk＞branch＞leaf.With the increase of the number of reserved sprout,the total sprout biomass increased at first and then reduced,in which seedlings of 2 reserved sprouts demonstrated the highest total biomass.However,the accumulation of biomass of 1 sprout reserved was significantly higher than that of other treatment.Reservation of no more than 2 sprouts per stump would achieve the different purposes to the plantation cultivation.关键词
