不同作物秸秆和淡紫拟青霉复配对番茄苗期生长及根结线虫病的影响
Effect of the Mixed Application of Different Crop Straws and Paecilomyces lilacinus on Tomato Seedling Growth and Root-knot Nematode Disease
摘要
Abstract
In this study,six different crop straws(wheat,maize,Jerusalem artichoke,marigold,potato onion and garlic)together with Paecilomyces lilacinus were chosen as experimental materials.Pot experiment was conducted to evaluate the effects of the straw-Paecilomyces lilacinus combination treatments on tomato seedling growth,root-knot nematode disease,soil nutrient status,soil enzyme activity and soil fungal communities.The results demonstrated that,except for garlic straw,other five crop straws combined with P.lilacinus all promoted the growth of tomato seedlings.Meanwhile,the combination of each six crop straws and P.lilacinus significantly alleviated the root-knot disease on tomato plants with the reduced number of tomato root knots.Soil nutrient status was ameliorated to different degrees with the combination of straws and P.lilacinus in addition.Besides,we also spotted that wheat and Jerusalem artichoke straws significantly improved soil invertase activities.Moreover,Jerusalem artichoke and maize straws increased the relative abundance of plant-beneficial fungal genus in the soil.It is well worth mentioning that each combination of crop straws enhanced the colonization of P.lilacinus in soil.In summary,we concluded that the combination of different crop straws can promote the colonization of P.lilacinus in the soil thus improve the biocontrol effect of P.lilacinus against tomato root-knot nematodes.The combination of Jerusalem artichoke straw and P.lilacinus has the best effect among all six combinations,which could be a potential environmental friendly strategy in dealing with tomato root-knot disease in future cropping practice.关键词
