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.
