    • 摘要: 研制室内渗透试验装置,通过对比试验,研究百喜草根系对砂质黏土渗透性能的影响,同时进行染色示踪优先流试验,探究百喜草根系对砂质黏土渗透性能的影响机理。结果表明,百喜草根系能较大幅度提高砂质黏土的渗透系数,其渗透系数是无根系土体的7.1~20.4倍;土体渗透系数随百喜草根系质量的增加而增大;渗透系数随土体深度的增大而减小,深度20~30 cm处有根系砂质黏土的渗透系数接近素土;根系的生长促进了土体内优先流的产生,有根系砂质黏土的染色面积占比及优先流路径长度均大于素土。

    • 摘要: 为探究干旱逆境下百喜草根、叶的联系与区别,研究以野生百喜草(Paspalum notatum)为研究试材,分别进行0(CK)、1、3、5、7、14、21、28 d的干旱胁迫处理,测定百喜草根、叶在不同时间干旱胁迫下渗透调节物质、抗氧化酶活性、丙二醛含量、细胞膜透性以及叶绿素含量的变化,对比百喜草根、叶在干旱胁迫下的生理反应.结果表明:随着干旱胁迫时间的延长,百喜草叶片和根系中可溶性蛋白含量、脯氨酸含量、丙二醛含量、细胞膜透性和CAT活性均呈逐渐上升趋势;可溶性糖、SOD活性呈先升后降趋势;POD呈逐渐下降趋势;3种叶绿素含量均呈先下降后上升最后又下降的变化趋势.干旱胁迫初期,SOD和CAT为百喜草根、叶的主要抗氧化物酶.随着胁迫加重,根系抗氧化物酶变为SOD,叶片为CAT和POD,干旱对根系的CAT和叶片的SOD、POD的影响显著.渗透调节和光合作用调节的部位主要是叶片.本研究为提高百喜草耐旱性提供了理论依据.%To investigate the correlation and difference between Paspalum notatum's leaf and root under drought adversity, this study tested the physiological responses of wild Paspalum notatum's leaf and root under 0 (CK), 1, 3, 5, 7, 14, 21, and 28 d drought stress treatment. These physiological responses include osmotic regulating substance, antioxidant enzyme activity, malonaldehyde content, cell membrane permeability, and chlorophyll content. According to the results, the soluble protein content, proline concentration, malonaldehyde content, cell membrane permeability and CAT activity in Paspalum notatum's leaf and root tended to increase with the prolongation of drought stress; the soluble sugar content and SOD activity first increased and then decreased; POD dropped gradually; the contents of chlorophyll a, b and total chlorophyll first declined, then mounted, and lastly dropped again. During the early stage of drought stress, SOD and CAT acted as the main antioxidant enzymes in Paspalum notatum's leaf and root. However, with the aggravation of drought stress the predominant antioxidant enzymes became SOD in the root system whereas CAT and POD in the leaf. It implicates drought has a strong influence on root's CAT and leaf's SOD and POD. Leaf is the major organ regulating the osmosis and photosynthesis of Paspalum notatum. The findings can provide a useful theoretical basis for improving Paspalum notatum's drought tolerance.

    • 摘要: 红壤区水库消落带植被恢复难度高,目前相关研究较少.文章通过研究在野外模拟红壤区水库消落带水位变化,表明百喜草对水淹环境有较好的适应能力,与岸坡种植无差异;混植香根草后其指标呈现更加稳定甚至叶宽、分蘖数有一定升高的趋势;能够改善土壤酸碱度、提高或稳定有机质、P、N、K含量,具有活化土壤速效养分的性能.单种和混植香根草均可推荐作为红壤区周调节水库消落带植被恢复的植物种,并提供了香根草作为百喜草共生草种的成功案例,针对性提出了减缓低温与水淹叠加效应、混植机理研究等后续研究方向.

    • 摘要: 为明确红壤坡地不同雨强下养分流失的途径和规律,研究百喜草(Paspalum natatu)全园覆盖、全园敷盖、全园裸露3种坡地利用类型下地表径流、壤中流、泥沙中总氮(TN)、总磷(TP)迁移特性及流失总量.结果表明:(1)不同雨型下采取生态措施(百喜草全园覆盖、全园敷盖)对TN、TP浓度起到明显的控制作用,其中百喜草全园覆盖(活地被植物)效果更佳;(2)不同雨型下不同处理径流中氮、磷的流失主要集中在径流初期,后期均匀稳定;(3)雨型越小,径流携带养分流失量占养分总流失量的比例越大,不同雨型中,清水径流携带的养分流失几乎可忽略不计,泥沙携带的养分才是真正的养分流失根源;(4)以TP为例,壤中流的浓度随深度的增加而减小,且浓度随壤中流流速的增大而减小,但壤中流单位时间内的流失量整体趋于平缓,壤中流及地下径流携带的养分可忽略不计.研究结果对科学制定红壤坡地养分管理措施、防治农业面源污染具有重要意义.

    • 摘要: 为探讨水土保持草种在重金属污染矿山废弃地植被恢复中应用的可行性,以南方地区水土流失治理中广泛应用的草种百喜草为试验材料,设置不同Pb浓度(150,250,500,1000,1500和2500 mg/kg)的室内土培模拟胁迫试验,定量测定不同Pb胁迫浓度、不同胁迫时间百喜草的叶绿素荧光、SPAD值、叶绿素含量、抗氧化酶活性及MDA含量等指标,分析百喜草对Pb胁迫的生理响应.结果表明,在试验初期(8月),Pb胁迫对百喜草的叶绿素荧光特性具有一定抑制作用,但随胁迫时间的增加,在试验后期(9和10月)则表现出显著的促进作用(P<0.05);Pb胁迫对百喜草SPAD值和叶绿素含量有一定抑制作用,但作用并不显著(P>0.05);Pb胁迫对百喜草的POD和SOD活性均具有一定促进作用,但对百喜草CAT活性无显著影响(P>0.05);铅胁迫增大百喜草体内MDA含量,但高浓度Pb胁迫(1500和2500mg/kg)条件下,百喜草体内MDA含量与对照无显著差异(P>0.05).以上结果表明,Pb胁迫对百喜草生理特性有一定抑制作用,但抑制作用并不显著.百喜草可通过提高叶绿素荧光特性和抗氧化酶(POD和SOD)活性,减轻Pb胁迫的危害,以适应Pb胁迫逆境环境.%Paspalum notatum is considered one of the best grass species for controlling soil and water loss in south China.To test the feasibility of P.notatum as a restoration plant in mining wasteland,a pot experiment was undertaken with various concentrations of lead (Pb) (150,250,500,1000,1500 and 2500 mg/kg).Chlorophyll fluorescence,SPAD value,chlorophyll content,antioxidative enzyme activities and malondialdehyde content were measured to investigate physiological responses to Pb stress.The inhibitory effect of Pb stress on chlorophyll fluorescence was observed at the early stage (August),while significant promotion was found at later stages (September and October).Pb stress inhibited the SPAD value of chlorophyll and the chlorophyll content of P.notatum,but no significant differences from the control were observed.Pb stress promoted the activities of peroxidase and superoxide dismutase,but showed little effect on catalase activity.Malondialdehyde content of P.notatum increased under Pb stress,but there were no significant differences from the control at higher Pb concentrations.These results demonstrate that Pb stress inhibits some physiological characteristics in P.notatum and that the antioxidant system and chlorophyll fluorescence may play important roles in alleviating Pb toxicity.

    • 摘要: Lanthanum (La) is one of the most vital and active rare earth elements.It can promote seed germination,increase crop output,and enhance plant resistance to environmental stresses.Paspalum notatum,a warm season turfgrass commonly used for conserving soil and water in Guangzhou,was selected to study the effect of La on root growth.Seven-day-old seedlings of P.notatum were grown in hydroponic conditions in an acid solution containing 0.9 μmol/L AP+ with and without 0.3 μmol/L La3+.Root morphology,the root dry weight/fresh weight ratio,and root activity were evaluated after 2,4,and 6 d of treatment.The addition of La3+ to the acidic Al3+ solution resulted in increased axial root length,root surface area,number of root tips,root volume,and root activity of P.notatum seedlings.These findings indicated that La can promote the root growth of P.notatum seedlings under Al3+ stress.%镧是稀土元素中最重要和最活泼的元素,具有促进种子萌发、提高作物产量和增强抵御逆境胁迫等作用.研究以华南地区水土保持常用的百喜草幼苗为材料,通过水培实验探究在酸性铝胁迫条件下镧对百喜草幼苗根生长的影响.实验在0.9 μmol/L Al3+的酸性铝胁迫水培条件下,以添加0.3 μ.mol/L的La3+作为处理,在水培的第2,4,6天,分别测定根系形态、根干鲜比、根茎比、根系活力.结果表明,在酸性铝胁迫水溶液中添加La3+,可提高幼苗的主根长、根表面积、根尖数、根体积、根干鲜比、根茎比、根系活力,说明在酸性铝胁迫条件下,镧元素可以促进百喜草幼苗根系的生长.
