摘　　要：鲁梅克斯(Rumex patientia×Rumex tianschanicus cv.Rumex)具有抗寒、耐盐碱、营养价值高等特点,是畜牧业上广泛应用的牧草,而EM菌生物有机肥可以提高作物的产量和品质,改良土壤,因此,施用EM菌生物有机肥对鲁梅克斯种植的推广具有重要的意义。本研究以从俄罗斯引进的鲁梅克斯品种(ЩавельЧемпион)和国内的鲁梅克斯K-1杂交酸模品种为材料,在鲁梅克斯种植过程中施用EM菌生物有机肥,研究此有机肥对牧草的农艺特性及品质的影响。结果表明,EM菌生物有机肥的施加,能够有效地促进鲁梅克斯的生长发育,明显地增加引进和国内品种的产量,显著地提高牧草的经济效益(P<0.05),并且可以显著地提高鲁梅克斯叶簇期叶片中叶绿素的含量(P<0.05),但对单宁含量影响不显著(P>0.05)。对引进品种施用EM菌有机肥时,发现其品质也显著地提高(P<0.05)。综上研究可知,在鲁梅克斯的种植过程中施加EM菌生物有机肥,不仅能够显著提高牧草的农艺特性,同时也能有效提高其品质。Rumexhas 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 Rumexplanting iseconomically important.We used the Russian Rumexspecies（ЩавельЧемпион）and domestic varieties Rumex K-1as material,spraying EM biological organic fertilizer in Rumexplanting 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 Rumexleaf 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.
