摘要
在连续两茬菠菜盆栽试验中,施用不同的微生物菌糠,通过测定菠菜的株高、根长、生物产量,收获后土壤碱解氮、有效磷、速效钾、有机质含量,研究了不同有益微生物组合加菌糠对菠菜生长和土壤养分的影响。结果表明:几种有益微生物组合加菌糠皆可以促进菠菜生长、增加产量和提高土壤养分,以微生物组合1+菌糠处理效果最好。
Two continuous rotations of spinach pot experiment were conducted together with the application of different beneficial effective microorganism and residue of mushroom medium in a glass greenhouse to study the influences of microbial manures(beneficial microorganisms + residue of mushroom medium)on spinach growth and soil nutrients by measuring plant height,root length and biological yield of spinach,and by determining changes of soil OM,alkaline hydrolysis N,available P and available K contents after harvesting each rotation of spinachThe results indicated that microbial manures(beneficial microorganisms + residue of mushroom medium)promoted spinach growth,increased spinach yield and were conducive to improvement of soil fertilityTreatment 2(beneficial microorganisms 1+residue of mushroom medium)had the best effects among all the beneficial microbial treatments
