摘要
研究TSINGKE保水剂对室内绿化植物绿萝的生理生化特性以及植物形态的影响,为保水剂在室内绿化植物抗旱方面的应用提供参考。使用绿萝作为试验对象,在自然干旱胁迫条件下,采用控水盆栽的方法,使添加的保水剂用量和盆土质量比分别为0(对照),0.05%,0.10%,0.15%,0.20%,检测绿萝外部形态指标和内部生理指标的变化。结果表明,施加不同浓度的保水剂后,绿萝在不同时期表现不同,初期各项指标差距较小,后期差异较大,对照组指标变化的时间早于试验组,总体表现为0.10%处理>0.15%处理>0.20%处理>0.05%处理>0处理,可知一定浓度的保水剂可以延缓绿萝衰败和提高保水抗旱能力,浓度为0.10%的保水剂表现最佳。在自然干旱胁迫的条件下,绿萝的生长和生物量都会受到不同情况的抑制,在添加保水剂的试验组中可以看到其所受到的抑制作用明显小于对照。添加TSINGKE保水剂对绿萝的外部形态和生理指标都会有一定作用。施加不同浓度的保水剂之后,绿萝的生长和生理指标会表现出不同程度的变化。施加保水剂可以提高吸水保水能力,减缓绿萝的衰老进程,提高绿萝对干旱胁迫的抗性。因此,在后期将保水剂投入到实际应用过程中,需要在结合不同植物研究制定不同的保水剂施加方案,以充分发挥保水剂的保水抗旱能力。
The purpose of this study was to study the effects of TSINGKE water retaining agent on physiological and biochemical characteristics and plant morphology of indoor greening plant Epipremnum aureum,so as to provide reference for the application of water retaining agent in drought resistance of indoor greening plants.The method was to use Epipremnum aureum as the experimental object,under natural drought stress,using water control pot culture method,make the dosage of water retaining agent and the weight ratio of basin to soil 0(control),0.05%,0.10%,0.15%,0.20% concentration gradient respectively,to detect the changes of external morphological indexes and internal physiological indexes of Epipremnum aureum.The results showed that after the application of different concentrations of water retaining agent,the performance of lüluo was different in different periods,the difference of each index in the early stage was small,and the difference in the later stage was large.The index change time of the control group was earlier than that of the experimental group,and the overall performance was as follows 0.10% treatment>0.15% treatment>0.20% treatment>0.05% treatment>0 treatment,it cluld be seen that a certain concentration of water retaining agent could delay the decline of green pineapple and improve the ability of water retaining and drought resistance,and the water retaining agent with the concentration of 0.10% had the best performance.The results showed that under drought stress,the growth and biomass of Epipremnum aureum were inhibited under different conditions.In the experimental group with water retaining agent,the inhibition effect was significantly less than that of the control group.The results showed that the addition of TSINGKE water retaining agent had a certain effect on the external morphology and physiological indexes of Epipremnum aureum.After the application of different concentrations of water retaining agent,the growth and physiological indexes of Epipremnum aureum would show varying degrees of change.The application of water retaining agent could improve the ability of water absorption and water retention,slow down the senescence process and improve the resistance to drought stress.Therefore,in the later stage of the water retaining agent into the practical application process,we need to combine different plants to develop different water retaining agent application scheme,in order to give full play to the water retaining and drought resistance ability of water retaining agent.
