摘要
[目的]研究仿生林环境与大棚环境朱砂根生长性状的差异。[方法]采用2年生朱砂根籽播容器苗，在大棚环境和秃瓣杜英仿生林环境中挂牌标号，测定苗木地径、高度、当年新梢数等指标。[结果]研究表明，仿生林环境的朱砂根籽播客器苗苗木地径生长速率在7月15日～8月1日这段时间的生长速率明显高于大棚环境，增长33．3％以上，而同时期的大棚环境中只增长10．5％。在8月以后二者增长速率较为一致，差距不大。对比苗高生长，由于大棚的遮阴可人为控制，因此在7～8月，大棚环境的朱砂根一直保持增长，在以后有个明显的停顿期，然后又有比较快的增长。[结论]大棚环境和仿生林环境中朱砂根生长总体差距不大，说明仿生林栽培可以替代大棚栽培，从而有效降低朱砂根栽培成本。
[ Objective ] Growth traits difference of Ardisia crenata under the bionic and greenhouse environment was studied. [ Method ] With biennial Ardisia crenata container seedlings, the seedling ground diameter, height and other indicators were investigated under the bionic and greenhouse environment. [ Result] The seedling ground diameter growth rate in July 15 to August 1 under bionic environment was significantly higher than the greenhouse environment. After August, the growth rates under the two kinds of circumstances were consistent. Because of the greenhouse shade can be artificially controlled, Ardisia crenata seedling height kept growing in July and August after the pause period and fast growth. [ Conclusion ] The Ardisia crenata growth differences under the bionic and greenhouse enviromnent were not obviously. Bionic forests can replace greenhouse cultivation, which effectively reduce the cost of cultivation.
