- 摘要:
- 混播构建野花组合景观时，其不同植物种间竞争与共存问题是植物景观形态与质量可持续性营造的理论依据。现以赛菊芋（Heliopsis helianthoides）、宿根亚麻（Linum perenne）、蓝蓟(Echium vulgare)3种植物为例，采用露地直播的方法，设置3种植物单独播种和混合播种2种播种模式（3种材料单独播种CKY、CKM、CKJ，T1处理宿根亚麻和赛菊芋1∶1混播，T2处理宿根亚麻和蓝蓟1∶1混播，T3处理赛菊芋和蓝蓟1∶1混播，T4处理宿根亚麻、赛菊芋和蓝蓟1∶1∶1混播），对不同播种模式下3种植物的株高生长量、相对生物量（RY）、相对密度（RD）、竞争率（CR）和相对产量总值（RYT）进行分析，研究了3种供试植物在等比例混播中的竞争关系与共存问题，及构建野花组合植物景观过程中的竞争关系与共存机制。结果表明：3种植物混播中竞争力表现为蓝蓟＞赛菊芋＞宿根亚麻。其中与宿根亚麻的混播促进了赛菊芋的生长，与其它植物的混播均对宿根亚麻的生长产生了抑制作用而对蓝蓟无显著的影响。在等比例混播的条件下，T1、T2、T3、T4处理均不具备混播花卉植物群落的稳定性，将3种植物应用于混播植物景观时应适当降低蓝蓟的混播比例，而提高宿根亚麻的混播比例，从而保证第2年景观的可持续性并提高植物群落稳定性。
- Abstract:
- The competition and coexistence of different plant species was the theoretical basis for the sustainable construction of flower landscape morphology and quality.In this study, Heliopsis helianthoides,Linum perenne and Echium vulgare were used to construct the flower landscape,two sowing modes were set for outdoor broadcast (single sowing of Heliopsis helianthoides,single sowing of Linum perenne,single sowing of Echium vulgare,Linum perenne and Heliopsis helianthoides in mixture 1∶1,Heliopsis helianthoides and Echium vulgare in mixture 1∶1,Linum perenne,Heliopsis helianthoides and Echium vulgare in mixture 1∶1∶1).High growth rate,relative biomass (RY),relative density (RD),competitive rate (CR) and total relative yield (RYT) of the three plants under different sowing modes were analyzed.In this way,that competition and coexistence mechanism of the three plants were investigated in equal proportion.The results showed that the competitiveness of the three plants was as follows:Echium vulgare>Heliopsis helianthoides>Linum perenne.Among them,the mixed seeding with Linum perenne promoted the growth of Heliopsis helianthoides,and the mixed seeding with other plants had an inhibitory effect on the growth of Linum perenne,but had no significant effect on the growth of Echium vulgare.Under the condition of such as proportion of mixed seeding,T1,T2,T3,T4 treatment did not have the stability of mixed flowers plant community,was applied to three plants mixed seeding plant landscape should be appropriate to reduce the mixed proportion of Echium vulgare,and improved the perennial root flax mixed seeding rate,so as to ensure the sustainability of the second year in a landscape and enhances the stability of plant community.
