Abstract

This study was conducted to investigate the response of date palm (Phoenix dactylifera, L.) cv Zaghloul, to nine different fertilizer treatments i.e. Control (1.5 N), full nitrogen (N) dose (100%) as mineral fertilizer (recommended rate), quarter organic fertilizers + 3/4 mineral, half-N dose as organic fertilizers + half as mineral, full N dose as organic fertilizer, quarter organic fertilizers + 3/4 mineral + bio-fertilizers (EM). half-N dose as organic fertilizers + half as mineral+ bio-fertilizers, full N dose as organic fertilizer+ bio-fertilizers and bio-fertilizers. The experimental design was complete randomize block design with three replicates under El Adlia, Blbas, Sharkia Governorate, Egypt during two successive years (2017 and 2018). The results showed that full N dose as organic fertilizer+ bio-fertilizers gave the highest leaf number/palm, leaf length and leaf area index. Applied the full N dose as organic fertilizer+ bio-fertilizers gave the highest number of leaflets/leaf and leaflet length whereas; addition bio-fertilizers only produced the highest value of leaflet width. Also, our results clear that added half N dose as organic fertilizers + half as mineral enhanced the leaf chlorophyll content, but the addition full N dose as organic fertilizer+ bio-fertilizers increased carotenoids content. Conclusively, from previous results, it can concluded that organic and bio-fertilizers enhancement all vegetative growth parameters of Zaghloul date palm cv. To reduce dates pollution, prefer replacement mineral fertilizer by organic and bio-fertilizers.

矿肥、有机肥和生物肥对扎格鲁枣树生长的影响

本试验研究了枣椰树(Phoenix dactylifera, L.) cv Zaghloul对对照(1.5 N)、全氮(N)用量(100%)作为矿物肥(推荐用量)、四分之一有机肥+ 3/4矿物肥、半氮有机肥+一半矿物肥、全氮有机肥、四分之一有机肥+ 3/4矿物肥(EM) 9种不同施肥处理的响应。一半氮量为有机肥+一半无机+生物肥，全氮量为有机肥+生物肥和生物肥。试验设计为完全随机区组设计，连续2年(2017年和2018年)在埃及Sharkia省El Adlia, Blbas, El Adlia, Blbas, 3个重复。结果表明，全氮有机肥+生物肥处理的叶数/掌数、叶长和叶面积指数最高。施用全氮有机肥+生物肥可获得最高的小叶/叶数和小叶长度;添加生物肥料只产生最高的单叶宽度值。同时，我们的研究结果表明，添加一半氮量的有机肥+一半无机肥可提高叶片叶绿素含量，而添加全氮量的有机肥+生物肥可提高叶片类胡萝卜素含量。综上所述，有机肥和生物肥对枣树的所有营养生长参数均有促进作用。为减少红枣污染，建议用有机和生物肥料代替矿物肥料。
