摘要:
以连作党参植株为试材，采用单因素随机区组试验，以无外源物质处理的党参为对照，分析28-高芸苔素内酯灌根和叶喷、枯草芽孢杆菌、解淀粉芽孢杆菌和氨基酸水溶肥处理对连作党参生理生化、产量及品质的影响，以期为缓解党参连作障碍、提升党参植株抗逆性及品质提供参考依据。结果表明：与对照相比，28-高芸苔素内酯处理显著增强根系活力，诱导过氧化氢酶活性增高，降低丙二醛和游离脯氨酸含量，提高了清除自由基速率。此外，该处理还显著增加了党参产量、炔苷和多糖含量，且灌根较叶喷效果显著。微生物菌肥处理提高了叶绿素和类胡萝卜素含量，降低叶片可溶性蛋白质含量和超氧化物歧化酶活性，使过氧化物酶活性升高至正常水平，诱导抗性产生并积累干物质，但枯草芽孢杆菌较解淀粉芽孢杆菌处理效应减弱。氨基酸水溶肥处理使灰分含量下降，炔苷含量较对照显著增加24.49%。综上，外源处理均有效提高连作党参叶片叶绿素含量、平衡渗透调节系统，增强抗氧化防御系统，促进光合作用，增强根系活力以吸收养分，从而提升党参产量和品质，其中0.01% 28-高芸苔素内酯灌根和氨基酸水溶肥处理在增产提质方面表现尤为突出。
Abstract:
Taking the continuous cropping Codonopsis as the research object,the single factor randomized block test was used to analyze the effects of 28-homobrassinolide root irrigation and leaf spraying,Bacillus subtilis,Bacillus amyloliquefaciens and amino acid water-soluble fertilizer treatment on the physiology and biochemistry,yield and quality of continuous cropping Codonopsis,in order to alleviate the continuous cropping obstacles of Codonopsis improve the stress resistance and quality of Codonopsis plants.The results showed that compared with the control，28-homobrassinolide treatment significantly enhanced root activity，induced increased catalase activity，decreased malondialdehyde and free proline content，and increased the rate of free radical scavenging.In addition，the treatment also significantly increased the yield，alkyne glycosides and polysaccharide content of Codonopsis，and the root irrigation effect was significantly higher than that of leaf spraying.Microbial fertilizer treatment increased the contents of chlorophyll and carotenoids，reduced the soluble protein content and superoxide dismutase activity in leaves，increased the peroxidase activity to normal levels，induced resistance generation and accumulated dry matter，but the effect of Bacillus subtilis was weaker than that of Bacillus amyloliquefaciens.The ash content decreased by amino acid water-soluble fertilizer treatment，and the alkyne glycoside content increased significantly by 24.49% compared with CK.In conclusion，exogenous treatments were effective in increasing the chlorophyll content，balancing the osmotic regulation system，enhancing the antioxidant defense system，promoting photosynthesis，and enhancing the root activity to absorb nutrients，thereby improving the yield and quality of Codonopsis，among which the 0.01% 28-high brassinolide root irrigation and amino acid water-soluble fertilizer treatments were particularly prominent in increasing yield and improving quality.
