针对宁夏贺兰山东麓酿酒葡萄产区土壤瘠薄、肥料利用率低等问题,以4年生"蛇龙珠"为研究对象,分别设计了常规施肥、施羊粪有机肥、施酵素菌有机肥、施酵素菌有机-无机复混肥、施电解锰渣复混肥5个处理,探讨有机培肥对酿酒葡萄生长发育、产量、品质以及土壤化学性质的影响。结果表明:与常规施肥相比,羊粪有机肥显著降低了土壤pH和全盐,同时提高了土壤有机质、碱解氮、有效磷、速效钾的含量,土壤培肥效果较好;酵素菌有机-无机复混肥比单施化肥或酵素菌肥更有利于提高酿酒葡萄的品质及产量;电解锰渣复混肥促进植株光合作用,增加干物质积累量。综合分析,酵素菌有机无机复混肥更适合贺兰山东麓酿酒葡萄的优质高效生产。
To solve the problems of barren soil and low efficiency of fertilizer in wine grape cultivation region in the east of Helan Mountain.The paper discussed the impact of organic fertilization on the growth,yield,quality and soil chemical properties of wine grapes ‘Cabernet gemisch'through field experiments:conventional fertilizing,sheep feces,enzyme microorgainsm organic fertilizer,eletrolytic manganese residue compound fertilizer.Compared with conventional fertilization,the results showed that the treatment of sheep feces not only reduced soil pH and total salt significantly,but also increased soil organic matter,available nitrogen,available phosphorus,available potassium content and it had distinct impact on soil structure.Enzyme microorganism organic-inorganic compound fertilizer was more advantageous to enhance the wine grape quality and yield than chemical fertilizer applied only and fermented manure applied only.Electrolytic manganese residue compound fertilizer contained a variety of medium trace elements,which benefited plant photosynthesis and increased the amount of dry matter accumulation.Through comprehensive analysis,enzyme microorganism organic-inorganic compound fertilizer was more suitable for the high quality and efficient production of wine grapes in the east of Helan Mountain.
