| 摘 要： | 多粘类芽孢杆菌(Paenibacillus polymyxa)隶属类芽孢杆菌属,其有利于促进植物生长和营养吸收.为探讨该菌株对植物生长及营养品质的应用价值,将该菌株与化肥进行不同配施处理,进行生菜盆栽试验.结果表明,多粘类芽孢杆菌剂具有解磷、解钾能力;菌剂对生菜地上部分有促生作用,使得生菜植株鲜质量、单株叶片数的增加趋势都非常明显,其植株鲜质量与空白相比最大增加387.60%;菌剂对根系生长的促进作用也非常明显,氮钾肥与菌剂配施可使根鲜质量增加373.00%;在优化生菜食用品质的基础上,菌剂与化肥配施,增加了生菜维生素C质量分数,达到9.96mg/100g,同时又降低其亚硝酸盐含量.综上所述,多粘类芽孢杆菌菌剂与化肥配施后促生效果较好,可促进生菜的生长及其品质的提高.

| Abstract: | The Paenibacillus polymyxa strain belongs to the Paenibacillus,which is advantageous for the promotion of plant gowth and nutrient absorption.The strain was treated with chemical fertilizer under different combinations to explore the application value to plant growth and nutrient quality.The results showed that P.polymyxa had the ability to release phosphorus and potassium.In addition,combined with chemical fertilizers,the strain had a growth promoting effect on lettuce,which increased the fresh weight,numbers of leaves per plant significantly.The fresh weight and root weight were increased by387.60% and 373.00% respectively,compared with the blank control group.The content of vitamin C in the treatment that combined application of P.polymyxaand chemical fertilizers increased to 9.96 mg/100 g,with the content of nitrite decreased.In summary,P.polymyxa and chemical fertilizers could have good growth-promoting effects after application and obtained higher quality of lettuces. |
