The Key Techniques for Establishment of Fast-growing and High-yielding Plantations

The establishment of fast-growing and high-yielding plantations of superior quality is dependent on advanced forest technology. Six technical measures are recommended in this paper, i.e. setting up tree cultivation varieties, selecting superior clones, adopting advanced propagation technology, reforming nursery practice, enforcing site selection and taking necessary cultivation measures. Ligni-culture got late developed in China, but the conditions are getting ripe, A set of cultivation varieties of commercial forest have been breeded by the mass of forest farmers and experts, clones of many tree species have been selected, such as poplar,Chinese fir, paulownia tree, locust and disease-resistant elm, etc, high effective and broad spectrum of root-promoting powder have been developed and extensively used in forestry and fruit trees, a set of superior fungus of masson7s pine, slash pine, loblolly pine and eucalypts have been selected, the symbiotic nitrogen-fixing technique of non-leguminous trees also reach the advanced level in th,e world, rapid progress have been made in the engineering afforestation arid the techniques for cultivation practised in China in recent years.Hong Jusheng is vice president of the Chinese Academy of Forestry, research fellow and expert in forest tree breeding.Hou Yuanzhao is director of the Information Research Institute, CAF, expert in information research on forestry.
