柿子酒渣与牛粪混合发酵有机肥对菠菜产量和品质的影响

为了使柿子加工废弃物—酒渣得到资源化利用,延长柿子产业链,解决废弃物污染环境的问题。研究利用柿子酒渣与牛粪混合发酵生产的有机肥与牛粪、膨化鸡粪3种肥料进行了菠菜盆栽效果试验,采用3处理4水平的随机区组设计,共设柿子酒渣与牛粪混合有机肥、牛粪和膨化鸡粪等3个处理,每个处理又按土肥比9:1、8:2、7:3、6:4分为4种施肥水平,重复3次,测试菠菜的产量指标和品质指标,以评价柿子酒渣与牛粪混合发酵有机肥仔菠菜上的使用效果。试验结果表明:与膨化鸡粪和牛粪比较,柿子酒渣与牛粪混合发酵有机肥更能促进菠菜的生长和改善菠菜的品质。柿子酒渣与牛粪混合发酵有机肥有明显促进菠菜茎叶与根系生长、增加生物量、提高维生素C含量和减少草酸和硝酸盐积累的效果。综合评价柿子酒渣与牛粪混合发酵有机肥以土肥比7:3施肥处理为最好,菠菜地上及地下部分增产最多维生素C含量最高草酸含量最低。

Effect of Persimmon Wine Stillage and Cattle Manure Ferment Organic Fertilizer on spinach Yield and Quality

By this experiment, the organic fertilizer of persimmon wine stillage and cattle manure, cattle manure, chicken manure were used as vegetable fertilizer for spinach, The purpose was to examine the effects of three organic manure on spinach growth and quality. The pot experiment was conducted in May, 2005. It was composed of three treatments, including co-composting of persimmon wine stillage and cattle manure, cattle manure, chicken manure. Each treatment had four fertilizer rates (the soil and manure ratio of culture medium is 9:1?8:2?7:3 and 6:4 ) , and Each fertilizer treatment was repeated six times. The result suggested that: the co-composting of persimmon wine stillage and cattle manure can improve both the growth and the quality of spinach much more than cattle manure and chicken manure. the co-composting of persimmon wine stillage and cattle manure significantly promoted the stem and foliage growth of spinach, improved produce, heightened Vc content, and reduced the accumulation of oxalic acid and nitrate, synthetically evaluate, the culture medium that the soil and manure ratio is 7:3 is the best treatment, the over ground and the underground increase production of spinach was the most, Vc content was the highest, and the oxalic acid content was lowest.
