Abstract:
The phosphorus-solubilizing bacteria and potassium-dissolving bacteria were used as the research object,the effects of rhizosphere nutrient environment of pepper were studied by method of applying fertilizer in rhizosphere of field in order to solve the problem of pepper continuous cropping obstacles in Ningxia Pengyang.The results showed that,soil salinity content were significantly reduced in TR1 treatment(phosphorus-solubilizing bacteria),TR2 treatment (potassium-dissolving bacteria) and TR3 treatment (phosphorus-solubilizing bacteria and potassium-dissolving bacteria) treatment,decreased by 49.8%-56.94%.In the initial stage of pepper fruit setting,the available nitrogen content were increased in the treatments which added phosphorus-solubilizing bacteria and potassium-dissolving bacteria.The phosphorus-solubilizing bacteria treatment had no significant effect on available potassium.Applied potassium-dissolving bacteria could significantly increase soil available potassium content,and release more phosphorus from soil than added phosphorus-solubilizing bacteria.Cause of the superposition effect of phosphorus-solubilizing bacteria and potassium-dissolving bacteria combined application,the content of soil available nitrogen,phosphorus and potassium in TR3 treatment was significantly higher than other treatments,and with the number of applications increased,the effect was more pronounced.The yield of pepper per 667 m2 in TR3 treatment reached 4 878 kg,which was 14.5% higher than that of CK.Therefore,in the production,the combined application of phosphorus-solubilizing bacteria and potassium-dissolving bacteria was better,and the application should be continued multiple times.
