Effects of EM biological organic fertilizer on growth characteristics and quality of Rumex

Rumex has the characteristics of higher cold resistance, salt tolerance and nutritional value, it's widely used in animal husbandry. The EM bio-organic fertilizer can increase the yield and quality of crops, andimprove soil. Therefore, the promotion of EM biological organic fertilizer on Rumex planting iseconomically important. We used the Russian Rumex species(Щавель Чемпион)and domestic varieties Rumex K-1 as material, spraying EM biological organic fertilizer in Rumex planting area to investigate the effects of organic manure on forage agronomic characteristics and quality. The results indicated that EM microbial bio-organic fertilizer can effectively promote the growth and development of Rumex, It significantly improved the economic benefit of forage grass. EM biological organic fertilizer applied can significantly improve the chlorophyll content of the leaves in Rumex leaf cluster period, but effect on tannin content was not significant. The quality of imported EM bacteria could be improved significantly by using the organic fertilizer. These results indicated that the biological organic fertilizer could not only improve the agronomic characteristics of the pasture, but also improve the quality of the EM during the cultivation of Rumex.
