摘要
【目的】研究微量元素对灰枣产量和品质的影响,为新疆枣产量提高及品质改良提供理论基础。【方法】采用树干注射的方式在灰枣的萌芽期配施微量元素肥铁锰锌,并对树体的生长指标进行测定。【结果】各施肥处理对灰枣生长的促进作用都以施肥处理5(铁锰中量,锌高量)最优,其干径增长量、基径增长量、枣吊增长量、单果重和产量分别是对照的1.25、2.00、1.26、1.47和1.21倍;枣果铁、锰、锌和钙的含量分别是对照的1.46、1.26、1.37和1.08倍,糖酸比为43.75。其它各施肥处理也表现类似的结果。【结论】采用注射方式在灰枣栽植过程中配合施用铁肥,不仅能促进树体的生长,对其营养品质提高也具有一定的作用。
[Objective] Trace element plays an important role in plant development process,analysis of the effect of the grey jujube yield and quality is helpful to enrich jujube trace element fertilizer theory and for Xinjiang jujube yields and qualihty improvement work,thus providing certain theoretical basis.[Method]The experiment was conducted in the way of trunk injection in jujube budding,flowering and date fruit expanding period,and the tree body growth index was determined.[Result] The optimal effect of fertilization treatment on gray jujube growth was found in treatment 5 which scapus number,the base stem number,weight of single fruit and yield were 1.25,2.00,1.26,1.47 and 1.21 times of the contrast.The nutritional contents such as Fe,Mn and Zn in this treatment,were 1.46,1.26,1.37 and 1.08 times of the contrast.Sugar acid ratio was 43.75.Other fertilizer treatments displayed similar results.[Conclusion] In the process of planting the Ziziphus Jujuba cv.Huizao with Fe fertilizer injection application,it not only can promote the growth of tree body,it is also of a certain help to other nutritional quality improving.
