羊粪对酸枣幼苗生长及营养吸收的影响

摘要

为配制酸枣育苗基质,合理施用羊粪,研究了施用羊粪对酸枣生长和营养吸收的影响.结果表明:适量施用羊粪可显著促进酸枣幼苗生长,株高、分枝数和生物量提高,根冠比降低.同时,随着羊粪施用量的增加,酸枣幼苗营养改善,并增加氮磷钾吸收.因此,在基质和果园中,适量施用羊粪可培育壮苗和促进酸枣幼苗的生长.%The present experiment is carried out to study the influence of sheep manure fertilization on the growth and nutrient uptake by the seedlings of Z. Jujuba, so as to prepare for seedling substrate of Z. Jujuba and to fertilizing sheep manure rationally. The results showed that the increment of plant height, branch and biomass was significant in contrast to root-shoot ratio which decreased, indicating the growth promotion of jujube. Simultaneously, sheep manure improved seedling nutrition and promoted the absorption of nitrogen, phosphorus and potassium by the seedlings. Therefore, the proper addition of sheep manure into culture mediums and orchard soils is beneficial to produce fine quality seedlings and promote jujube seedling growth.
