【摘要】 为解决土壤连作障碍对蔬菜生长发育的不利影响，本研究以连作3年的芹菜土壤为研究对象，采用随机区组试验，设置5种处理：单独施加生物炭（BC）、单独施加Bacillus subtilis菌剂（BS）、生物炭与菌剂混合施加（BB）、施加生物炭载B. subtilis菌粒（BP）、不施加生物炭与菌剂（CK），盆栽种植芹菜，测定其生长与品质指标，探究生物炭和B. subtilis对连作芹菜生长的影响。结果表明，BB、BP处理组芹菜的生长和品质指标都高于其他土壤处理组，BP处理组的芹菜鲜质量、可溶性蛋白含量以及纤维素含量均显著高于BB处理组，分别为60.25 g/棵、27.25 mg/g、2.48%，其他指标两处理间无显著差异。不同土壤处理组芹菜的生长和品质指标都高于CK处理，其中BP处理组各指标值最高，尤其是芹菜鲜质量，增幅高达226.56%。因此，施加生物炭载B. subtilis菌粒提高了连作芹菜生长指标与品质，为农业生产上缓解蔬菜连作障碍奠定了理论基础。更多还原

【Abstract】 In order to solve the adverse effects of continuous cropping disorder on the growth and development of vegetables, the celery soil with three years of continuous cropping was researched in the study. A randomized block potted design was conducted with five treatments: Biochar alone(BC), Bacillus subtilis alone(BS), biochar mixed with B. subtilis(BB), pellets of B. subtilis inoculated biochar(BP) and no biochar and B.subtilis(CK). The growth and quality indexes of celery were determined to obtain the effects of biochar and B.subtilis on the growth of continuous cropping. The results showed that the growth and quality indexes of celery in BB and BP treatment groups were higher than those in other treatment groups. The fresh mass, soluble protein content, and cellulose content of celery in the BP group, which were 60.25 g/plant, 27.25 mg/g and2.48%, respectively, were significantly higher than those in the BB treatment group. There were no significant differences in the other indexes between the BP and BB treatments. The growth and quality indexes of celery in treatment groups were higher than those in CK group. Moreover, the indexes of celery in BP treatment group were the highest, especially for the fresh mass, which increased by 226.56% over CK group. Therefore, the growth and quality indexes of celery were improved by the application of the pellets of B. subtilis inoculated biochar, which laied a theoretical foundation for their application to alleviate celery continuous cropping obstacle in agriculture.更多还原
