中文摘要	采用保水剂(处理Ⅰ)、生根粉(处理Ⅱ)、矮壮素(处理Ⅲ)与多效唑(处理Ⅳ)4种生物制剂,研究了不同生物制剂对2年生沙漠植物约书亚树幼苗的成活、生长及生理生化指标的影响,并对其影响效益作出综合评价。结果表明:处理Ⅰ及处理Ⅱ均能显著提高约书亚树幼苗的成活率,分别高于对照10.78%及5.43%,处理Ⅲ及处理Ⅳ较对照的成活率分别降低了15.78%及11.25%。处理Ⅰ显著促进了幼苗生长并提高了约书亚树幼苗的光合生理指标、渗透调节物质含量、POD酶及CAT酶活性。处理Ⅱ对幼苗株型无显著影响,抗氧化酶活性及脯氨酸含量均显著高于对照。处理Ⅲ使幼苗株高显著低于其他处理,并主要影响幼苗的游离脯氨酸含量及抗氧化酶活性指标。处理Ⅳ促进幼苗地径增粗和植株矮化,并影响植物的光合生理及SOD酶活性指标。利用主成分分析得出,约书亚树幼苗的株型及光合生理因子在综合评价中权重最大,为68.11%;D值的排序为:处理Ⅰ>处理Ⅳ>处理Ⅱ>对照>处理Ⅲ,说明保水剂为最佳生物制剂,显著提高了植物的成活率及生理生化指标,并能显著促进幼苗生长;其次为生根粉,通过影响渗透调节物质和抗氧化酶活性指标促使成活率显著提高;多效唑虽然对植物的影响效益较大,但其浓度可能不适宜植物成活,对其施用浓度需要进一步研究。
英文摘要	Four biological agents,water retaining agent(TⅠ),ABT (TⅡ),CCC (TⅢ) and PP333(TⅣ),were applied to 2-year-old desert plant Yucca brevifolia seedlings to study the effect and function of these biological agents on survival rate,growth,physiological and biochemical indexes of it,and a comprehensive evaluation on their impact efficiency was drawn out.The results were as follows:TⅠ and TⅡ significantly increased the survival rates of seedlings,which were 10.78% and 5.43% higher than CK;but survival rates of TⅢ and TⅣ were 15.78% and 11.25% lower than CK.TⅠ significantly promoted the growth of Y.brevifolia seedlings and increased photosynthetic physiology indexes,content of osmoregulation substances,the activity of POD and CAT of Y.brevifolia seedlings.Compared with CK,TⅡ made no significant changes on the growth index,but both antioxidant enzyme activity and proline content of TⅡ were significantly higher.TⅢ made the height of seedlings significantly lower than that of other treatments,and it mainly had effects on the free proline content and antioxidant enzyme activity indicators of the seedlings.TⅣ thickened the diameter and shortened the height of seedlings,and had an impact on photosynthetic and SOD activity.Through principal component analysis,plant type and photosynthetic physiological factor had the maximum weight in a comprehensive evaluation of Y.brevifolia seedlings,as 68.11%;D-value was in the sequence of TⅠ>TⅣ>TⅡ>CK>TⅢ.It revealed that water retaining agent was the best biological agent,which had significantly increased the survival rates and physiological and biochemical indexes of Y.brevifolia seedlings,and notably promoted its growth at the same time.Next to it was ABT3,which had significantly increased the survival rate by influencing the indicators of osmotic adjustment substances and antioxidant enzyme activities.Although PP333 had a greater impact on the survival rate of plants,its concentration might be unsuitable to its survival.Its concentration for application needs to be further studied.
