不同基质组合对神东矿区文冠果生长的影响

目的]为在神东矿区大面积种植文冠果提供参考资料。方法]对文冠果施以不同种类的底肥和不同剂量的保水剂,以成活率、地径增长量、新梢均长和最长新梢长为指标研究不同基质组合对其生长的影响。结果]底肥对文冠果的成活率和地径增长量影响最显著,底肥与保水剂的交互作用对其新梢均长影响最显著,底肥、保水剂、底肥与保水剂的交互作用对其最长新梢长影响均不显著。羊粪与150 g保水剂组合的文冠果的成活率最高,其均值可达78.38%,地径增长量最大,其均值可达1.337 mm。羊粪与50 g保水剂组合的文冠果的新梢增长量最大,均值为102.8 mm。结论]在神东矿区栽植文冠果移植苗时施用羊粪＋150 g保水剂的基质组合比较好。

Effects of Different Medium Combinations on the Growth of Xanthoceras sorbifolia in Shendong Mining Area

Objective] The purpose was to supply reference data for planting Xanthoceras sorbifolia in large scale in Shendong mining area.Method] The X.sorbifolia was fertilized with different kinds of basal fertilizers and different doses of water retaining agent,with survival rate,increment of ground diameter,average length of new shoots and length of the longest new shoot as indices,the effects of different medium combinations on its growth were studied.Result] The effect of basal fertilizer on the survival rate and increment of ground diameter of X.sorbifolia was most significant.The effect of interaction between basal fertilizer and water retaining agent on the average length of new shoots was most significant.All the effects of basal fertilizer,water retaining agent and their interaction on the length of the longest new shoot were not significant.The survival rate of X.sorbifolia in the combination of sheep manure and 150 g water retaining agent was highest and its average value could be up to 78.38%;the increment of ground diameter of X.sorbifolia in this combination was most and its average value could be up to 1.337 mm.The increment of new shoots of X.sorbifolia in the combination of sheep manure and 50 g water retaining agent was most and its average value was 102.8 mm.Conclusion] It was better to apply medium combination sheep manure + 150 g water retaining agent for planting transplanted X.sorbifolia seedlings in Shengdong mining area.
