马尾松低产林采伐和改造试验技术研究

A PRELIMINARY STUDY ON REGIMES OF CLEAR CUT AND REGENERATION OF THE DETERIOUATED PINUS MASSONIANA FOREST

通过１１．６公顷马尾松低产林采伐改造营林试验，初步筛选出马尾松低产林采伐 方式和树种配置最优组合类型；针对农区人口稠密、交通方便这一特点，在造 林三年内实行矮秆作物间作措施，既解决幼林抚育和保护需要经费，又给农民 增加一定的经济收益。该项技术适合目前四川丘陵马尾松林区生产现状．

Based on the clear cut and regeneration experiments on 11. 6 hacters of the deteriorated Pinus massoniana forest, a best pattern of clear-cut regime after combined by tree spcies option was preliminarily summarized, and a typically comprehensive technolodgy on inter cropping seedlings with annual crops has effectively contributed to more intensive forest managements in the densely populated hilly areas.
