腐植酸生物有机肥在盆栽香葱上的试验研究

Experimental Research of Humic Acid Microbial Organic Fertilizer on Potted Chive

利用褐煤等经过复合微生物高温堆腐发酵后添加特定功能菌制备成腐植酸生物有机肥,并将该肥用于盆栽香葱试验。结果表明:腐植酸生物有机肥使香葱株高、分蘖数、丛株重增加,使根系发达、根系活力增强、叶绿素含量增加,还能优化土壤微生物群落,为香葱生长发育奠定基础。施用腐植酸生物有机肥能使在化肥减量20%情况下,产量不降反增。综上所述,腐植酸生物有机肥可改善土壤理化性状、增效化肥、增强抗逆,促进香葱生长、增产和品质改善。

Humic acid microbial organic fertilizer was made from ligite and others by adding specific functional bacteria after composting and fermentation by composite microorganisms at high temperature.The results showed that humic acid microbial organic fertilizercould increase chive plant height,tiller number,cluster weight,root number and activity,chlorophyll content,and could optimize soil microbial communities,which laid a foundation for the growth and development of chive.The yield increased while reduce chemical fertilizer usage by 20%.In conclusion,humic acid microbial organic fertilizer could promote the growth,increase the yield and improve the quality by improving soil physical and chemical properties,fertilizer efficiency and stress resistance.
