Effects of Different Concentrations of MSG Tailing Solution on the Properties of Mycorrhizal Bran-depressed Saline Conditioner
In order to verify the improvement effect of MSG tailing solution on the characteristics of mycorrhizal bran-convex saline-alkaline conditioner,six treatments were set up to formulate different concentrations of MSG tailing solution mixture of 5%,10%,15%,20%,25%and 0%(control),and the effects on the pH,grain formation rate,effective phosphorus,ammonium nitrogen,alkaline dissolved nitrogen and organic matter content of the conditioner were determined by the additional application of MSG tailing solution.The results showed that compared with CK,pH values of mycorrhizal bran-convex saline-alkaline conditioners dropped to different levels,among which the pH value of T5(25%)decreased by 1.1 at the lowest level,the grain formation rate increased by 11.97 percen tage point,the effective phosphorus increased by 263.33 mg/kg,ammonium nitrogen increased by 104.87 mg/kg,alkaline nitrogen increased by 1,279.68 mg/kg,and the organic matter increased by 14.02 g/kg,where as the effects on quick-acting potassium content and total sodium were not significant.In conclusion,MSG tailing solution improved the characteristics of mycorrhizal bran-convex saline conditioner significantly with optimum effects showed at the 25%of MSG tailing solution mixture.
