Problems And Its Countermeasures in Pulpwood Cultivation of Masson Pine

In recent ten years, great progress has been made in construction of plantation base and researches on genetic improvement and cultivation techniques of masson pine for pulpwood. In this paper a brief summary on construction and researches of pulpwood plantation base of masson pine was made which dealt with the problems in such fields as cultivation objectives of plantation, breeding, selection and extension of the superior genotypes, site selection, planting density, rotation age, fertilization in young and middle aged plantation and establishment of mixed forest. The corresponding countermeasures were put forward to guide the sustainable forest management of “the first workshop”of paper/pulp making industry.
