| 摘 要： | 叶片缺铁黄化是制约金丝小枣优质高产的重要生产问题。为改善金丝小枣果实品质及产量,采用树干注射方式在金丝小枣生育期补充树体铁素营养,以期研究注射铁肥对金丝小枣树体生长指标、产量及品质的影响。试验设置注射不含铁基础营养液、含0.2、0.3和0.4 g/L Fe-EDTA基础营养液4个处理。结果表明,树干注射不同浓度铁均能促进金丝小枣的生长,0.2 g/L Fe-EDTA处理显著促进了果实的生长发育,使横径、纵径、单果重、可溶性糖含量相对基液对照分别提高了6.6%、4.2%、6.2%和7.9%,0.3 g/L Fe-EDTA处理显著提高了一级枣果比例。因此,采用注射方式对金丝小枣补施铁肥是金丝小枣高产、优质、高效率生产的有效技术途径。

| Abstract: | Leaf yellowing caused by iron(Fe)deficiency is one of the most important limiting factors for high yield and high quality production of Jujube.In order to provide a theoretical basis for increasing yield and improving quality of golden thread jujube production in Laoling,Fe fertilization experiment was conducted to study the impact of injection different concentrations of Fe EDTA solution in tree trunk on nutrient content,fruit development,yield and quality of golden silk thread jujube.Four treatments were set up,included non ferrous basic nutrient solution,0.2 g/L Fe EDTA basic nutrient solution,0.3 g/L Fe EDTA basic nutrient solution and 0.4 g/L Fe EDTA basic nutrient solution.The preliminary results showed that the trunk injection of different concentration of Fe EDTA solution improved the growth and fruit development of jujube.The 0.2 g/L Fe EDTA basic nutrient solution treatment significantly promoted the growth and development of fruit, and increased the ratio of transverse diameter, longitudinal diameter, single fruit weight and soluble sugar content by 6.6%, 4.2%, 6.2% and 7.9% respectively.The 0.3 g/L Fe EDTA basic nutrient solution treatment significantly increased the proportion of high quality jujub.Thus,trunk injection of Fe fertilizer was a useful ways for high yield and high quality golden silk jujube production. |
