| 摘 要： | 采用盆栽试验研究了拮抗菌发酵的生物有机肥(BIO-36和BIO-23)对茄子植株的生长以及青枯病防治效果的影响。结果表明:①苗期茄子植株生长30天时,施用BIO-36和BIO-23的处理鲜重显著增加,尤其BIO-36处理的茄子根系的总长、总表面积和总体积提高8.58倍、2.74倍和16.57倍;②茄子苗移栽35天时,施用BIO-36和BIO-23的处理株高、地上部和地下部生物量都有显著提高,青枯病的发病率低,分别为4.1%和8.3%;③施用BIO-36和BIO-23的处理的茄子根际的真菌数量比对照CK增加了4.1~4.6倍和3.89~4.64倍,放线菌数量增加了3.38~3.78倍和3.08~3.47倍,根际茄科劳尔氏菌的数量分别为1.5×105cfu/g、2.1×105cfu/g,都控制在106cfu/g数量级以下,而对照处理数量级达到了1.23×106cfu/g。施用拮抗菌发酵的生物有机肥能显著促进茄子植株的生长,有效地降低茄子青枯病的发病率。

| Abstract: | Pot experiments were carried out to investigate the effects of two new bio-organic fertilizers (BIO-36 and BIO-23) fermented with different antagonistic strains on plant growth and the suppression on the disease. The results were as follows. (1) Application of BIO-36 and BIO-23 significantly increased fresh weights of eggplant seedlings after grown in nursery cups for 30 days. BIO-36 showed most distinct root growth enhancement, being 8.48 to 8.69 times higher in total root length, 2.70 to 2.77 times higher in total surface root area, and 15.5 to 18 times higher in root volume than control. (2) Plant height, shoot and root biomass in the treatments of BIO-36 and BIO-23 were significantly increased after grown for 35 days in the big pots, in which soil inoculated with the pathogen and seedlings were transplanted from nursery cups, while disease incidence of the bacterial wilt was significantly reduced to 4.1% for BIO-36 and 8.3% for BIO-23 in contrast to 91.7% for control. (3) BIO-36 and BIO-23 increased rhizosphere fungi by 4.1 to 4.6 and 3.89 to 4.64 times and rhizosphere actinomycetes by 3.38 to 3.78 times and 3.08 to 3.47 times, respectively, as compared with control, but did not significantly change bacterial counts. However, BIO-36 and BIO-23 reduced the counts of Ralstonia solanacearum in rhizosphere by almost one order of magnitude when compared with control. Therefore, the application of the bio-organic fertilizers could effectively control the bacterial wilt disease and promote plant growth of eggplant. |
