苗木是造林的物质基础,苗木质量的优劣是决定造林成败的关键。回顾我省三十多年来,造林成活率低、保存率不高、幼树生长差的主要原因之一是由于有些地区使用不合规格的苗木造林所致,影响了我省造林事业的发展。为了纠正某些地区忽视苗木质量、单纯追求数量的倾向,实现苗木标准化、社会化和商品化,以适应造林事业的发展和林业现代化建设的需要,本文根据笔者1982—84年参加制订全省苗木质量、产量标准调查工作,结合科研、生产单位的育苗技术经验总结,就如何实现苗木标准化,提高育苗质量的苗木施肥、密度和分级等技术问题进行初步探讨。
Seedlings are the material basis for afforestation, the merits of seedling quality is the key to determining the success or failure of afforestation. Recalling the past 30 years in our province, the survival rate of afforestation is low, the preservation rate is not high, poor growth of saplings is one of the main reasons for the use of substandard seedlings in some areas due to afforestation, affecting the development of afforestation in our province. In order to correct the ignorance of seedling quality in some areas, simply pursue the tendency of quantity, realize the standardization, socialization and commercialization of seedlings in order to adapt to the development of afforestation and the need of forestry modernization construction, according to the author in 1982-84 to participate in the formulation of the province’s seedlings Quality and yield standards. Based on the experience of nursery techniques of scientific research and production units, the technical problems of how to standardize nursery stock and improve seedling fertility, density and grading of nursery are discussed.
