湿地松原产美国,现已成为我国南方主要造林树种之一。但是育苗仍靠经验,许多苗圃还不能主动通过栽培技术的控制与调节,使苗木的生长发育与其生存的环境相协调,以达到高产、优质、低耗的目的。而栽培技术规范化的研究就是在总结群众经验的基础上,通过多年的田间试验与验证以及对试验数据的定性定量分析,选出优化育苗技术方案,使之科学化,再去指导生产。于1982——1984年对湖南、湖北、安徽、江苏四个省30个苗圃进行调查、总结,用系统聚类方法研究苗木的品质指标;并用正交设计方
Slash pine native to the United States, has now become one of the main afforestation species in southern China. However, nursery is still relying on experience, many nurseries can not take the initiative through the control and regulation of cultivation techniques, seedling growth and development and its living environment to achieve high yield, high quality, low consumption purposes. The standardization of cultivation techniques is based on the summary of the masses of experience, through many years of field trials and validation and qualitative and quantitative analysis of experimental data, select the optimal plan of nursery technology to make it scientific and go to guide the production. In 1982-1984, 30 nurseries in Hunan, Hubei, Anhui and Jiangsu Provinces were surveyed and concluded. The quality indexes of seedlings were studied by systematic clustering method.
