设施软枣猕猴桃树体不同生育期Fe、Mn、Cu、Zn养分需求规律研究
Research on the Nutrient Requirements of Fe,Mn,Cu,and Zn for Facility Actinidia arguta Trees at Different Reproductive Stages
摘要
Abstract
[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 charac-teristics 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 con-tents 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 distri-bution 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 develop-ment,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.关键词
