摘要
为了解味精尾液对菌糠-凹凸棒土盐碱地调理剂特性的改良效果,将不同浓度味精尾液分别拌入菌糠-凹凸棒土盐碱地调理剂原料中,研究不同浓度的味精尾液(0%、5%、10%、15%、20%、25%)对菌糠-凹凸棒土盐碱地调理剂pH、成粒率及有效磷、铵态氮、碱解氮、有机质含量的影响.结果表明,增施味精尾液后,菌糠-凹凸棒土盐碱地调理剂pH有不同程度降低,其中味精尾液混合液体积浓度 25%处理的pH最低,较对照不添加味精尾液低 1.1;成粒率、有效磷、铵态氮、碱解氮、有机质含量均有所上升.其中以味精尾液混合液25%处理最好,与对照相比,成粒率增加 11.97 个百分点,有效磷增加 263.33 mg/kg,铵态氮增加 104.87 mg/kg,碱解氮增加 1 279.68 mg/kg,有机质增加 14.02 g/kg.对速效钾和钠的影响不大.说明味精尾液改良菌糠-凹凸棒土盐碱地调理剂的效果明显,且以 25%的味精尾液浓度最好.
Abstract
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.
