摘要
以1年生木荷容器苗为研究材料,在相同管理措施、环境因子下,测量经过3组不同移苗时间及2组不同缓释肥浓度处理的木荷容器苗基径及高生长情况。研究结果表明,在3 kg/m3和4 kg/m3两个不同缓释肥浓度下,6组共计360株试验苗木高生长差异显著。在3 kg/m3和4 kg/m3两个不同缓释肥浓度下,基径生长与移苗时间相关,移苗时间提前,苗木基径生长差异性不显著;移苗时间延迟,苗木基径生长差异显著。提前苗木播种时间,在苗木3～5片真叶时移栽,加大缓释肥浓度,可提高苗木移栽成活率和苗木生长速度。
1-year-old container seedlings of Schima superba was selected as research materials in this experiment.Under the same management and environmental conditions,caliper and height of the Schima superba container seedling were measured with three different transplant times and two different concentrations of slow-release fertilizer.Results showed that,height growth of total 360 sample seedlings were different significantly under treatments in two different concentrations(3 kg/m3 and 4 kg/m3) of slow-release fertilizer;caliper growth was related to transplant time.With early transplant time there were no significant differences in caliper growth of seedlings transplanted early,whereas significant difference existed in caliper growth of seedlings transplanted later.Transplanting the seedlings early with 3-5 leaves and increaseing fertilizer concentration could help to increase the seedling survival percentage and seedling growth rate.
