马尾松枫香混交林营造技术研究

对马尾松枫香混交林的营造技术进行了调查分析和试验研究。结果表明，松枫混交林，能提高林地土壤肥力和蓄水保水能力。营造时，初植密度根据立地条件选用2500～3300株/hm^2，混交方式宜采用行带状、带状、星状。混交比例以枫香株数不超过30%为宜，同时应进行合理疏伐和疏枝。补值枫香是改造马尾松低产林分的有效措施。

Forestation Techniques for Mixed Stand of Pinus massoniana and Liquidambar formosana

The techniques for constructing mixed stand of Pinus massoniana and Liquidambar formosana were studied.The results showed that this kind of mixture was a good combination in maintaining soil fertility and site productivity of the stand in long term,when 25003330 trees per hectare were planted and the planting patterns of row banding,banding and star dotted adopted. The proportion of Liquidambar formosana in the mixed stand should not exceed 30%.Replanting is an effective measure in improving the productivity of lowyielded Pinus massoniana forest.
