平菇菌糠对园林花土基质改良的应用研究

The Application Research About the Influence of Mushroom Substrate on the Soil Character

栽培后的园林花池土壤贫瘠化且理化性状变劣,以平菇菌糠添加到花土中研究其改良效果。即菌糠晒干粉碎后按30%的体积比添加到园林花池土中,设对照;以矮牵牛花为试验植物移栽到基质中;矮牵牛花生长过程中分期调查其农艺性状变化;定期检测土壤有机质含量及微生物含量的变化,分析平菇菌糠对土壤改良的效果。结果表明:与对照相比,添加平菇菌糠的花池土的根际微生物数量明显增加、土壤中有机质含量增加;显著促进矮牵牛花的生长及开花。

Soil physicochemical properties deterioration after cultivation in the flower beds, reducing the effect of plant greening. With mushroom bran added to study the improvement effect of soil of flowers, that is The dried mushroom bran crushed is added to the soil in the flower beds by 30% volume ratio, meanwhile set up control; Petunia plants into the matrix for the test. The agronomic characters were investigated by stages and the soil organic matter content and microbial biomass were were tested by regularly to analysis of the effect of mushroom bran the soil improvement. The results showed that： compared with the control, The number of microorganisms in the rhizosphere soil of the flower beds and Soil organic matter content increased significantly after adding mushroom bran, so significantly promote Petunia growth and flowering, so the mushroom substrate adding into soil significantly promote to Petunia growth.
