沼肥施用方式对灰枣中矿质元素含量的影响

在不同沼肥施用方式条件下分析灰枣果实中主要矿质养分元素的含量,结果表明：不同沼肥施用方式处理的灰枣果实中氮、磷、钾的含量都表现为氮〉钾〉磷,果实中磷的含量在不同施肥方式中变化比较平缓,沼液喷施有利于灰枣果实对氮、钾元素的吸收和积累,而沼夜滴施则有利于磷素的吸收和积累;沼液喷施有利于提高灰枣果实中矿质元素铁、锌、铜、锰、钙、镁的含量,改善果实品质。不同沼肥施用方式中以沼液喷施效果最佳。

Influence on Content of Mineral Elements in Fruit of Huizao under Different Application Ways of Biogas Waste Fertilizer

Analyzing content of main mineral elements in fruit of Huizao under different application ways of biogas waste fertilizer.The results show that the content of N、P、K in fruit of Huizao is NKP,and the content of P is low and stably under different application ways of biogas waste fertilizer.The spray application of liquid manure is advantage for fruit of Huizao to assimilate and accumulate N、K,the dropping fertilization of liquid manure is advantage to assimilate and accumulate P.Meanwhile spray application can increase the contents of mineral elements Fe,Zn,Cu,Mn,Ca,Mg in fruit of Huizao,and improve the fruit quality.The effect of spray application is the best under different application ways of biogas waste fertilizer.
