针对黄土山地密植枣树土壤肥力低、树势弱、生长缓慢、枣果产量低、经济效益差以及缺乏合理施肥技术等问题,在山地红枣土壤肥力研究和田间微灌施肥试验的基础上,提出了山地矮化密植红枣高产优质的施肥时期、施肥用量与配比、施肥方法和叶面施肥浓度等技术,同时指出了枣树施肥中需要注意的技术问题。 According to the problems of low soil fertility, weak vigor, slow growth, low yield of jujube, poor economic benefit and lack of reasonable fertilization techniques in densely populated jujube tree in Loess Plateau, based on the study on soil fertility and fertilization experiment of field jujube, The techniques of high yield and high quality fertilization period, fertilization amount and proportion, fertilization method and foliar fertilizer concentration of dwarfing dense red dates in mountain area were put forward. At the same time, the technical problems needing attention in fertilization of jujube trees were pointed out.
