有益微生物组合加菌糠对小白菜生长及土壤养分的影响

Influences of Beneficial Microorganism Combination Adding Waste Material on

采用盆栽试验 ,通过测定小白菜的株高、叶片长、叶比重、叶面积和产量 ,土壤碱解氮、有效磷、速效钾含量 ,研究不同有益微生物组合加菌糠对小白菜生长和土壤养分的影响。结果表明 :施用有益微生物组合加菌糠可以促进小白菜生长、增加其产量和提高土壤养分含量。其中 ,以有益微生物组合链霉菌和巨大芽孢杆菌加菌糠的效果最好。

In pot test in a glass greenhouse the measurement on plant height and yield,leaf length and area,leaf-specific qravity of Brassica pekinesis,and on the changes of soil alkaline hydrolysis N, available P and available K contents after harvesting.Indicated that application the beneficial microorganisms combination adding waste meterial could promoted growth,increased yield of Brassica pekinesis and improve soil fertility.The beneficial microbial conbination (streptomycin and Bacillus megateriam) adding waste meterial had the best effects among all the beneficial microbial treatments.
