园林苗圃是整个城市园林绿化事业的重要组成部分,园林树木苗木又是城市园林绿化的重要物质基础,因此如何多快好省地生产园林苗木将直接关系到园林绿化的质量和进展。随着科学技术的不断发展,园林树木育苗新技术与常规育苗相比也有了新的进展,主要表现在繁殖材料的挖潛、容器的改进、基质的革命、温室的发展、除草方法的研究和生长调节剂的广泛应用等方面。园林苗木生产正在向机械化、工厂化、专业化方向发展。一、繁殖材料的挖潜园林树木的繁殖材料不外乎两大类:一是园林树木种子,二是园林树木植株营养器官的一部分。而在园林苗木生产中,较多使用的繁殖材料还是后者。用最少(或小)的繁殖材料,繁殖最多的园林树木植株,最大限度地挖掘材料潛在繁殖 Garden nursery is an important part of the city’s landscape afforestation. Garden tree nursery stock is also an important material foundation of city landscaping. Therefore, how to produce garden nursery stock quickly and economically will directly affect the quality and progress of landscaping. With the continuous development of science and technology, new progress has been made in the new technology of garden tree seedling compared with that of conventional seedling breeding. The main achievements are as follows: tapping the breeding material, improving the container, the revolution of the matrix, the development of the greenhouse, the research and growth of the weeding method Wide application of regulators and so on. Garden seedling production is to mechanization, industrialization, specialization direction. First, the recruitment of reproductive materials landscape trees reproductive material is nothing more than two categories: First, the trees, garden trees, trees and plants is part of vegetative organs of trees. In the production of garden seedlings, more reproductive material used or the latter. With the least (or small) propagation material, the most productive garden tree plants, to maximize the potential exploitation of the material
