摘要
在沼肥施用方式不同条件下分析红枣植株地上部分各器官N、P、K的含量。结果表明:不同沼肥施用方式处理的枣树对氮、磷、钾的吸收总量都表现为N>K>P,同时在整个生长过程中对磷素的吸收变化比较平缓;枣树地上部分植株各器官中的养分含量也均表现为N>K>P,与植株吸收总量保持一致;沼肥施用方式对枣树各器官中养分的含量产生了一定的影响,沼液喷施有利于植株对N、K养分的吸收和积累,而沼液滴施则有利于植株对P素的吸收和积累。
It was analyzed that the content of N,P,K in plant of Zizyphus jujube under different application ways of biogas waste fertilizer. The results showed that the total absorption content of N,P,K in plant of Zizyphus jujube was N〉 K〉P,and the absorption of P was low and stable in growth period of Zizyphus Jujube. The plant nutrient content of different organs was also N〉K〉P,it kept the same with the total absorption content of N,P,K in plant of Zizyphus jujube. The different application ways of biogas waste fertilizer caused obvious impacts on the plant nutrient content of different organizers, and the spray application of liquid manure was advantage for plant to absorb and accumulate nutrient N, K. The dropping fertilization of liquid manure was advantage for plant to absorb and accumulate nutrient P.
