- 摘要:
- 以中抗枯萎病西瓜品种“京欣1号”为试材，在温室栽培条件下，针对3种不同连作年限（3、7、12 a）的土壤，研究了接种丛枝菌根(AM)真菌对连作西瓜生长和枯萎病的影响。结果表明：接种AM真菌能显著提高西瓜根系菌根侵染率，且随着连作年限的增加，AM真菌侵染率逐渐降低;同时接种AM真菌均能提高不同连作年限处理西瓜植株的生物量，其中对连作3 a的处理增加效果最显著；虽然AM真菌不能防止连作西瓜枯萎病害的发生，但对其具有一定的防治效果，并且连作年限越短，AM真菌的防治效果越好。
- Abstract:
- Taking watermelon Fusarium wilt middle resistant cultivar ‘Jingxin No1’ as material，the effect of inoculating arbuscular mycorrhizal fungus on the growth and Fusarium wilt of continuous cropping watermelon were studied in soils continuously grown with watermelon for 3，7 and 12 years.The results showed that inoculating arbuscular mycorrhizal fungus could improve the fungus colonization rate，but it decreased with the increasing of replanting years.Arbuscular mycorrhizal fungus could improve the seedlings biomass of watermelon grown in different soils with different replanting years，especially in 3 years’ continuous cropping soil.Although arbuscular mycorrhizal fungus could not avoid the occurrence of Fusarium wilt disease，it had positive efficacy on disease control.The efficacy of arbuscular mycorrhizal fungus was greater as soil with shorter replanting years.
