容器苗大大简便了造林技术,尤其是栽植技术不如裸根苗要求的苛刻和严格。但容器苗造林仍有它自己的技术特点和要求,造林技术掌握不好,仍然不会取得理想的造林效果。为此,我们着重对容器苗的造林技术,和影响容器苗造林成活率的生态学和生物学因子进行了研究。现将初步成果整理分析如下: 一、进行全根造林和培养球状根苗木成活是一个苗木生理平衡问题,而主要又是水分平衡问题。裸根苗损伤了根系,栽植后地上部分所需要的水分和养料不能得到及时供应,苗木生长发育就会遭受严重影响,甚至死亡。容器苗由于根系保持完整,并带有营
Container seedling greatly facilitated afforestation techniques, especially planting techniques as bare rooted seedlings demanding and strict. However, container seedling afforestation still has its own technical features and requirements, afforestation technology is not good, still will not achieve the desired afforestation effect. To this end, we focus on container seedling afforestation techniques, and affect the container seedling afforestation survival rate of ecological and biological factors were studied. The preliminary results are now analyzed as follows: First, the whole root afforestation and cultivation Spherical root seedling survival is a physiological balance of seedlings, but the main problem is the water balance. Bare root seedlings damage the root system, after planting the ground part of the required moisture and nutrients can not be timely supply, growth and development of seedlings will suffer severely affected, and even death. Container seedlings due to the root system to maintain integrity, and with battalion
