[目的]该研究旨在探讨主干一次和二次环剥对葡萄树体营养及其分配规律的影响。[方法 ]以“玫瑰蜜”葡萄为试材,通过对主干进行一次和二次环剥后分析对剥痕上部的叶片、枝条和剥痕下部根系的碳氮营养、矿质营养及其分配规律的影响。[结果]环剥可显著提高剥痕上部的枝叶可溶性糖和淀粉等非结构碳含量,降低可溶性蛋白质和氮素营养含量,使碳氮比显著提高,其中一次环剥后叶的碳氮比峰值为9.04,二次环剥为5.35,而同一时期对照仅为4.89。环剥不仅显著降低了根系可溶性糖和淀粉等非结构碳含量,还显著降低了可溶性蛋白质和氮素营养含量,碳氮比也有不同程度的降低,其中一次环剥后其碳氮比的最低值仅为1.16,二次环剥为3.06,而同一时期对照为3.15。对碳氮营养的影响,一次环剥显著大于二次环剥。环剥还显著降低了叶片、枝条和根系中的磷、钾、铁、铜的含量。其中二次环剥对枝条、叶片中铁、铜元素的影响较大,且第一次采样的含量差异显著,叶片中的铁含量为75.05μg/g DW,而对照为85.29μg/g DW;枝条中的铁含量为76.45μg/g DW,铜含量为7.82μg/g DW,而对照分别为95.96μg/g DW和10.74μg/g DW。[结论]该研究为树体营养调节和保障环剥技术在“玫瑰蜜”葡萄生产中安全有效的应用奠定基础。
[Objective] The purpose of this study was to investigate the effects of primary and secondary girdling on the nutrition and distribution of grapevine. [Method] With “Rose honey” grape as test material, primary and secondary girdling were conducted to analyze the effects of carbon and nitrogen nutrition, mineral nutrition and its distribution on the leaves, The law of influence. [Result] Girdling significantly increased the content of non-structural carbon such as soluble sugar and starch in shoots and branches, reduced the content of soluble protein and nitrogen, and significantly increased the ratio of carbon to nitrogen. The peak of C / 9.04, the second stripping was 5.35, while the control of the same period was only 4.89. Girdling not only significantly reduced the content of non-structural carbon such as soluble sugar and starch in roots, but also significantly reduced the content of soluble protein and nitrogen, and the C / N ratio also decreased to some extent. The lowest C / N ratio Only 1.16, the second stripping was 3.06, compared with 3.15 for the same period. The impact of carbon and nitrogen nutrition, a significantly greater than the second circumcision girdling. Girdling also significantly reduced the content of phosphorus, potassium, iron and copper in leaves, shoots and roots. The secondary girdling had a significant effect on the contents of iron and copper in shoots and leaves, and the contents of the first sampling were significantly different. The content of iron in the leaves was 75.05μg / g DW, while the control was 85.29μg / g DW. The iron content was 76.45 μg / g DW and the copper content was 7.82 μg / g DW, while the controls were 95.96 μg / g DW and 10.74 μg / g DW, respectively. [Conclusion] The study laid the foundation for the regulation of tree nutrition and the protection of girdling technology in the safe and effective application of “Rose Honey” grape production.
