为了总结经验,更好地发展苗木生产,现对近几年来江苏省的苗木生产现状与展望论述如下.一、苗木生产现状(一)苗木生产实绩及其原因浅析 据统计,1984—1987年全省平均每年育苗16.4万亩,比1983年增长60%.以1985年育苗最多,达21.8万亩,其中观赏苗面积达11.0万亩,占总育苗面积的50%.这几年在育苗生产安排上,由过去的指令性生产转变为指导性计划,各地可根据需要自行安排育苗任务;在经营性质上,由生产型转变为经营型;在苗木品种上,也由培育单一造林用苗转变为多品种的造林苗和观赏苗,而且苗木产量和质量均有不同程度的提高,一般每公斤种子的产苗量,火炬松、湿地松由过去不足1万株提高到2万株左
In order to sum up experience and better development of seedling production, seedling production in Jiangsu Province in recent years, the status quo and prospects are discussed below.A seedling production status (A) seedling production performance and its causes According to statistics, 1984-1987 The province grows an average of 164,000 mu per year, an increase of 60% over that of 1983. In 1985, the largest number of nursery plants reached 218,000 mu, of which 110,000 mu were ornamental plants, accounting for 50% of the total nursery area. Arrangements, from the past mandatory instruction into a guiding plan, all localities can arrange their own nursery tasks according to need; in the nature of the operation, from production to management; in seedling varieties, but also by cultivating single afforestation seedlings change For many varieties of afforestation and ornamental seedlings, seedling yield and quality have varying degrees of increase, the general per kg seedling production, loblolly pine, slash pine from less than 10,000 in the past to 20000 left
