F01复合微生物菌剂对马铃薯种植土壤性质及产量品质的影响OA

Pot and field experiments were conducted to systematically evaluate the effect of F01 compound inoculant on soil properties,potato yield,and potato quality.The results were summarized as follows:(1)F01 compound inoculant increased the content of available nutrients in the soil.Applying F01 compound inoculant at 60-90 kg/hm2 significantly increased the content of available nitrogen,available phosphorus,and available potassium in the soil,and the application in the early and middle growth stages demonstrated particularly remarkable effect.However,excessive application inhibited the accumulation of soil nutrients.(2)F01 compound inoculant significantly improved the activities of urease,sucrase,catalase,and alkaline phosphatase in the soil.The medium dose treatment showed the best stability and comprehensive effect.(3)F01 compound inoculant increased the potato yield.Under field conditions,the F01 compound inoculant applied at 90 kg/hm2 increased the potato yield by 35.59%compared with the control group.In addition,it significantly increased the weight and number of tubers per plant and the commercial potato rate.(4)F01 compound inoculant showed the potential of improving the quality of potato tubers.It exerted a positive effect on crude protein content,but had no significant effect on dry matter or starch content,which may be related to the genetic characteristics of the fresh-eating potato variety'Jizhangshu 12'used.In summary,the F01 compound inoculant applied at 60-90 kg/hm2 achieved synergistic effect of soil improvement and yield and quality enhancement,demonstrating application potential and promotion value.In the future,exploration should be conducted on its adaptability and stability under different soil types and potato varieties.
