| 摘 要： | 采用树干注射的方式在灰枣的萌芽期、花期和果实生长期增施铁肥，并对树体的生长指标、产量和营养物质含量进行测定。结果显示：不同生长期增施铁肥对灰枣生长的促进作用都以萌芽期施肥处理Fe-2（3.0 g/株）最优，其干径增长量、基径增长量、枣吊增长量、单果质量和产量分别是对照的1.27、1.32、1.21、1.5和1.19倍；枣果铁、锰、锌和钙的含量分别是对照的1.63、1.44、1.04和1.24倍，糖酸比为56.02。在灰枣生长季节，采用树杆注射方式增施一定含量的铁肥，不仅能促进树体的生长，对其营养品质提高也有一定的作用。

| Abstract: | Trace element Fe plays an important role in plant development process, to analyze effects of Fe on the grey jujube yield and quality will enrich jujube trace element fertilizer research, and provide certain theoretical basis for yield and quality improvement of Xinjiang jujube production. Fe fertilizer was trunk-injected at the stages of jujube budding, flowering and fruit expanding. The tree body growth index, yield and nutrient content were measured. The results showed that the best effects of Fe trunk injection was detected in the treatment Fe-2 (3.0 g/plant) at the germination stage, and the corresponding indexes of scapus number, the base stem number,mass of single fruit and yield were 1.27, 1.32, 1.21, 1.5 and 1.19 times of the contrast. The contents of Fe, Mn, Zn and Ca in fruit were 1.63,1.44,1.04 and 1.24 times of the contrast, and sugar acid ratio was 56.02. Fe fertilizer injection in the process of planting Ziziphus jujuba cv.Huizao can not only promote growth of tree body, but also improve nutritional quality of Huizao fruit to some extent. |
