| 为了探索壳聚糖、碧护和酵素菌有机肥对香蕉尖孢镰刀菌和植株生长的影响规律，采用正交L8（27）
盆栽法研究壳聚糖、碧护、酵素菌等3 种生防制剂对不同抗性的香蕉组培苗诱导其抗尖孢镰刀菌的效果及对植
株生长和基质氮含量的影响。结果表明：（1）碧护制剂可显著抑制尖孢镰刀菌，显著促进香蕉植株株高和茎粗的
生长，显著提高栽培基质的碱解氮的含量。（2）酵素菌对香蕉尖孢镰刀菌、植株生长、基质氮含量的影响较小，壳
聚糖对“巴西”的诱导抗性大于“农科一号”，综合影响最小。（3）壳聚糖与酵素菌的交互效应显著，二者协同施用
对香蕉抗尖孢镰刀菌、植株生长、碱解氮含量均有较大影响，而壳聚糖与碧护间的交互效应很小。（4）香蕉枯萎病
病情与栽培基质的碱解氮含量间显著负相关，与植株茎粗和株高间不相关。本研究初步得出，壳聚糖、碧护和壳
聚糖复合酵素菌措施可提高香蕉对尖孢镰刀菌的抗性，它们对抗病性的提高与提高栽培基质的碱解氮含量紧密
相关，而与茎粗和株高不相关。 |
| 英文摘要: |
| The experiment was conducted to study the induced resistance to Fusarium oxysporum f. sp. cubense bybio-control agents including chitosan，VitaCat，enzyme bacteria，and investigate plant growth and nitrogen content ofbanana，with two different varieties of banana seedling in disease resistance as materials，by the design of L8（27）andpot culture. The results showed that VitaCat could significantly inhibit F. oxysporum f. sp. cubense，promote stem growingin height and diameter，increase nitrogen content of cultivation media significantly. Enzyme bacteria didn’t affect thesefeatures significantly. Chitosan had different effects on different banana variety，its effect on Baxi was higner than that onNongke No1.，and its comprehensive effect was the minimum. The interaction effect of chitosan and enzyme bacteria wassignificant，and the collaborative effect had great influence on banana resistance to F. oxysporum f. sp. cubense，plant growthand nitrogen content. But chitosan had no interaction effect with VitaCat. Banana wilt disease had significantly negativecorrelation with nitrogen content，but no relation with stemdiameter and height. The results indicated that，chitosan，VitaCat and chitosan combined with enzyme bacteriacould improve the induced resistance to F. oxysporumf. sp. cubense，which was relative to nitrogen content insubstrate，not to banana plant height and diameter. |
