不同育苗容器规格对红桦幼苗的形态和生物量的影响

本文通过对红桦采用不同类型和规格育苗试验,结果表明,托盘育苗能克服普通容器育苗(塑料袋)的侧根盘绕现象,空气切根能避免容器苗底部根系盘绕,而且也能避免人工修根感染。干旱地区托盘育苗适宜选用导根类托盘。攀西地区红桦容器育苗适宜采用H250导根线类托盘空气切根育苗,其平均苗高、地径、根干重、茎干重和叶干重分别达19.82cm、3.31mm、0.40g、0.31g和0.45g。

Effects of Different Seedling Container Size on Seedling Morphology and Biomass of Betula Albo-Sinensis Burk

This article is to seedling express albo-sinensis Burk, the results showed that the tray seedling by using the different types and specifications of Betula seedling can overcome the common phenomenon of container （plastic bags） of the lateral root coiling, air cutting root can avoid the bottom of the container seedlings roots coiled, and also can avoid infection of artificial root. Tray seedling selected for conducting root class tray in arid regions. Betula albo-sinensis Burk container seedling is suitable for use in Panxi region H250 air cutting root class tray seedling guide wire, its average seedling height, ground diameter, root dry weight, stem dry weight and authors respectively 19.82 cm, 3.31 mm, 0.40 g and 0.31 g and 0.45 g.
