摘要
在灵武长枣上叶面喷施1%、2%、3%、4%浓度的"魔粒丰",测定长枣形态指标、果实品质和光合作用,研究叶面喷施"魔粒丰"对灵武长枣生长的影响。结果表明:喷施"魔粒丰"能提高灵武长枣果实的纵横径、单果重和坐果率;叶面喷施3%浓度"魔粒丰",长枣果实有机酸含量较对照提高0.21%,叶面喷施1%浓度"魔粒丰"长枣果实Vc含量较对照提高2.8 mg/g。说明喷施"魔粒丰"对灵武长枣的形态生长没有明显影响,但能促进灵武长枣的光合作用,提高果实品质。
The fertilizer ＂Molifeng＂ with concentration of 1%, 2%, 3% and 4% were sprayed to the foliage of Ziziphus jujube Mill cv. Lingwuchangzao to study the influence of ＂Molifeng＂ on growth of the jujube by detecting the form, fruit quality and photosynthesis of the jujube. The results showed that the spray of ＂Molifeng＂ could increase the longitudinal diameter and diameter, weight and setting rate of the fruits. The organic acid content of the fruits was 0.21% higher with fertilizer ＂Molifeng＂ of 3% concentration compared with that of the control and with fertilizer ＂Molifeng＂ of 1% concentration, the Vc content of the fruits was 2.8 mg/g higher than that of the control. This indicates that though little effect on the growth of Ziziphus jujube Mill cv. Lingwuchangzao, the fertilizer ＂Molifeng＂ can enhance its photosynthesis and thus improve its quality.
