| 摘 要： | 为明确木霉菌剂对茉莉的促生作用和根际土壤微生物数量的影响,施用木霉菌剂后,田间测定茉莉的株高,并采用稀释分离法测定茉莉根围土壤真菌和细菌的数量。结果表明,在供试的3种木霉菌剂中,T9菌剂和H6菌剂可显著提高茉莉根围土壤的真菌数量,以T9菌剂处理的真菌数量最高,为14.19×104个/g,比对照增加了196.86%;3种木霉菌剂均能显著提高茉莉根围土壤的细菌数量,以T9菌剂处理的细菌数量最高,为21.68×106 CFU/g,比对照增加了222.14%。3种木霉菌剂对茉莉的生长均有一定的促进作用,以T9菌剂处理的株高最高,为43.37 cm,比对照提高了22.10%。T9菌剂可显著提高茉莉根际微生物的数量,还可促进茉莉的生长。

| Abstract: | To determine the effect of Trichoderma preparation on the growth promotion of Jasminum sambac and the amount of microorganism in rhizosphere soil, the plant height of J. sambac was measured in field after the application of Trichoderma preparation, and the amount of fungi and bacteria in rhizosphere soil was measured by dilution separation method. The results showed that, among the three Trichoderma preparations, T9 and H6 treatments could significantly increase the amount of fungi in the rhizosphere soil of J. sambac. The amount of fungi treated with T9 was the highest, which was 14.19×104 spore/g, 196.86% higher than that of the control. The amount of bacteria in the rhizosphere soil of J. sambac was significantly increased by three Trichoderma preparations, and the amount of bacteria treated with T9 was the highest, which was 21.68×106 CFU/g, 222.14% higher than that of the control. The growth of J. sambac was promoted by three kinds of Trichoderma preparations. The plant height treated with T9 was 43.37 cm, which was 22.10% higher than that of the control. Trichoderma preparation of T9 can significantly increase the amount of rhizosphere microorganisms and promote the growth of jasmine. |
