我们认为杂交杨在努力促进和维持一个能够生活的环境方面,和其它一些树种相比,杂交杨有较大的潜力。23年来,我们每年在我们的林场和苗圃地附近,栽植了杂交杨。假若我们能够把我们范围取得经验介绍给你们,可从以下方面去认识: 一、就土壤改良和造林而论杂交杨能改变象开矿挖出的泥土和岩石所破坏的土地、道路和火烧过的土地这样一类的环境,在10—20年内,变成有益的、高产森林。另外,水土保持工作者已经高兴的看到杂交杨能改变无生命的不毛之地成为森林,几乎可直接提供保护动物生活和极大地改善水土保持。
We believe Hybrid Poplar has great potential in promoting and sustaining a viable environment in comparison with some other tree species. For 23 years, we plant hybrid poplars every year near our woodlands and nurseries. If we are able to introduce our experience in this area to you, we can understand from the following aspects: First, in terms of soil improvement and afforestation, hybrid poplar can change the land, roads and burned-out land damaged by earth and rock excavated from mines Such a land-based environment will turn into productive and productive forests in 10 to 20 years. In addition, soil and water conservation workers have been happy to see that hybrid poplar can change inanimate barren land into a forest that can provide animal life almost directly and greatly improve soil and water conservation.
