现代林业育苗理念及技术分析

Analysis on the concept and technology of modern forestry seedling raising

介绍了现代林业育苗理念,如注重对苗木根系的培育,找到了提升苗木培育技术的关键点。根系发达的苗木在恶劣的环境中也能保持一定的生长态势。选择合适的栽培容器,要对苗木根系的生长状况进行基本预测,预先对容器进行处理,使容器能够满足苗木根系的生长需求。改变育苗容器的材料,以无纺布和轻基质材料为主,并通过机器对容器进行智能操作,对布缝进行焊接,对基质进行填充。分析了现代林业育苗技术,如无土栽培技术,可以通过水培的方式为苗木提供所需的营养成分。插条技术,保持土壤的湿润度,或使用垄作的方法使其保持水分。栽苗技术,用根系完好的育苗进行种植,该技术对苗木的生长环境要求较低,种植成活率较高。分植技术,把树木的枝、根、干作为原材料进行培育,操作简单,幼苗的生长速度较快,成活率较高。

This paper introduces the modern forestry seedling raising idea, such as paying attention to the cultivation of seedling root system, finding the key point of improving seedling cultivation technology, and seedling with developed root system can maintain a certain growth trend in harsh environment. Selecting suitable cultivation containers, we should make a basic prediction of the growth of seedling root system, and deal with the containers in advance, so that the containers can meet the growth needs of seedling root system. Changing the material of seedling container, mainly non-woven fabric and light matrix material. Intelligent operation of container is carried out by machine, the seam of cloth is welded, and the matrix is filled. The modern forestry seedling cultivation technology, such as soilless cultivation technology, can provide necessary nutrients for seedlings through hydroponics. The seedling cultivation technology, using the seedling with intact root system for planting, requires a lower growth environment of seedlings, and has a higher survival rate. The branch, root and stem of trees are used as raw materials for cultivation. The operation is simple, the growth rate of seedlings is faster and the survival rate is higher.
