摘要
【目的】计算不同生育阶段设施软枣猕猴桃树体各个组织器官Fe、Mn、Cu、Zn的吸收分配比率、吸收速率、累积量比例,探明软枣猕猴桃树体Fe、Mn、Cu、Zn的需求特征。【方法】以软枣猕猴桃树为试验材料,在年周期各个生育期挖出全株并分解采样,测定各个组织器官中Fe、Mn、Cu、Zn的含量。【结果】结果表明,萌芽期Fe、Mn、Cu、Zn吸收分配比率较高。始花期对Mn的需求量较多,对Fe、Cu、Zn的需求量较少。果实发育初期Fe、Mn、Zn的吸收分配比率占比全年吸收分配比率较大。果实发育中期Mn、Cu吸收分配比率较高。【结论】在萌芽期,施肥方式应为土壤追肥,所选肥料可为常规化肥,且施肥时间应保持一定间隔。在始花期,适宜采用追肥方式,并选用水溶性化肥,以土壤施肥为主,叶片喷洒为辅。在果实发育初期,树体对各种营养元素需求旺盛,需注重肥料的补充。在果实发育中期,则主要使用水溶性化肥。
【Objective】The absorption and allocation ratios,absorption rates,and accumulation proportions of Fe,Mn,Cu,and Zn in different plant tissues and organs were calculated at various phenological stages,elucidating the demand characteristics of these elements in Actinidia arguta trees.【Methods】Using Actinidia arguta trees as experimental materials,the entire plant was thoroughly excavated at each growth stage of the annual cycle,decomposed and sampled,and the nutrient contents of iron,manganese,copper,and zinc in various tissues and organs were determined.【Results】The results showed that the absorption and distribution ratios of iron,manganese,copper,and zinc were higher during the germination stage.At the beginning of the flowering period,there wais a higher demand for manganese and a lower demand for iron,copper,and zinc.In the early stage of fruit development,the absorption and distribution ratio of iron,manganese,and zinc accounts for a larger proportion of the annual absorption and distribution ratio.In the middle stage of fruit development,the absorption and distribution ratio of manganese and copper was relatively high.【Conclusion】The fertilization method during the germination stage is soil topdressing,and the selected fertilizer can be general chemical fertilizer,with a certain interval between fertilization times.At the beginning of the flowering period,the fertilization method is suitable for topdressing,and water-soluble chemical fertilizers are selected.Soil fertilization is the main method,supplemented by leaf spraying.In the early stage of fruit development,there is a high demand for various elements,and attention should be paid to the supplementation of fertilizers.In the middle stage of fruit development,water-soluble fertilizers are mainly used.
