摘要:
<正>杉木萌芽更新适于短轮伐作业,在实践中对其利弊尚存在争议。本文根据在苏南丘陵地区的长期试验,对萌芽林与实生林的生长、树干圆满度、树干基部弯曲率、根系分布与重量和更新费用作了分析比较,得出萌芽林无论在生长和干形上均不比实生林逊色,而投资却仅占实生林1/3,具有投资少,更新可靠,经济效益好的特点。文内还比较了伐桩萌条存留株数对高生长的影响,在去萌定株时以保留两株萌条者高生长最佳。
Abstract:
The sprout regeneration of Chinese fir (Cunninghamia lanceolate) is suitable to a short rotation. But there are arguments about its advantages and disadvantages in practice. The growth, stem fullness, rate of curve at butt, distribution and weight of root system, cost were compared between the seedling stand and the sprout stand. It is concluded that the sprout stand is not worse than the seedling stand in growth and stem while the investment in the sprout stand is only 1/3 as much as that in the seedling stand. The effect of different numbers of stump plant which remains on high growth has been studied. The optimun number of stump plant is 2.
