植物生长调节剂对哈密大枣采前落果、果实品质及产量的影响

Effect of Spraying Plant Hormone on Fruit Drop and Fruit Quality and Yield of Hami Jujube

【目的】调查叶面喷施植物生长调节剂及微量元素对哈密大枣的坐果率、品质及产量的影响,以期提高哈密大枣的种植效益。【方法】以哈密大枣果树为试验材料,在大枣幼果膨大期进行喷施不同浓度生长植物调节剂,每隔10 d喷施1次,共计喷施5次,收果时调查大枣的坐果率、果实品质及产量,并分析其经济效益。【结果】NAA 10 mg/L+水杨酸100 mg/L+黄腐酸微量元素在哈密大枣幼果时期进行叶面喷施,能够减少幼果5.64%脱落,其差异性显著(P<0.05);667 m2(1亩)增产5.06%,与对照相比差异性显著(P<0.05)。【结论】通过外源激素及补充微量元素的方法能够有效增加哈密大枣的种植效益。

【Objective】Effect of spraying plant Hormone and trace elements on fruit drop and fruit quality and Yield of Hami Jujube tree was studied to increase planting benefits.【Method】Taking Hami Jujube as trial materials,different concentration plant hormone were sprayed in the growth stage of young fruit for one time every 10days,sprayed total five times were sprayed,fruit of fragrant pear and fruit quality and yield were investigated,economic benefit was analyzed at last.【Result】 treatment of NAA 10mg mg/L and SA 100 mg/L and yellow humic acid composite trace elements was most obvious to reduce 5.64% of fruits drop,and increase 5.06% of yield（P0.05）.【Conclusion】Spraying plant Hormone and trace elements could decrease planting economic benefit of Hami Jujube trees.
