摘要: 研究氮、磷、钾的不同配施对灵武长枣(Ziziphus jujuba Mill. cv. Lingwu Changzao)营养生长与叶片养分含量的影响,在大田条件下控制氮、磷、钾肥的施用量,采用“3414”完全实施方案,5—9月每隔30 d测定灵武长枣枣吊长、枣吊粗、叶面积和叶片含水量以及叶片中的全氮、全磷和全钾含量。结果表明,适量增施氮、磷、钾肥均可明显提高灵武长枣枣吊长、枣吊粗、叶片叶绿素含量和叶片含水量,其中,N2P1K2(N 292.50 kg/hm2,P2O5 86.33 kg/hm2,K2O 115.65 kg/hm2)处理下枣吊长度和枣吊粗度最大;而在展叶期至坐果期氮、磷、钾合理配施可提高灵武长枣叶片中的全氮、全磷、全钾含量。其中N2P2K1(N 292.50 kg/hm2,P2O5 172.65 kg/hm2,K2O 57.83 kg/hm2)处理下叶片的全氮含量和全磷含量最高。

Abstract: The effects of formula fertilization of N, P and K on the vegetative growth and leaf nutrient content of Ziziphus jujuba Mill. cv. Lingwu Changzao were researched. The application amount of N, P and K fertilizer was controlled under field conditions, and the complete implementation scheme of “3414” was adopted from May to September. The shoots length, shoots diameter, single leaf area area and leaf water content and total nitrogen, total phosphorus and total potassium in leaves of Ziziphus jujuba Mill. cv. Lingwu Changzao were measured every 30 days. The results showed that the appropriate application of N, P and K fertilizers could significantly increase the shoots length, shoots diameter, leaf chlorophyll content and leaf water content of Ziziphus jujuba Mill. cv. Lingwu Changzao, and the treatment N2P1K2(N 292.50 kg/hm2,P2O5 86.33 kg/hm2,K2O 115.65 kg/hm2) was the largest in shoots length and shoots diameter. The rational application of N, P and K in the sprout leaves period to the fruiting stage can increase the total N, total P and total K content in the leaves of Ziziphus jujuba Mill. cv. Lingwu Changzao. Among them, the total N content and total P content of the leaves were the highest under treatment N2P2K1(N 292.50 kg/hm2,P2O5 172.65 kg/hm2,K2O 57.83 kg/hm2).
