- 摘要:
- 以骏枣为试材，研究其生育期内叶片和果实内11种矿质元素含量周年动态变化，以期改善骏枣营养环境，提高果实品质，为合理施肥提供参考依据。结果表明：骏枣在不同的生长发育阶段，叶片和果实内的矿质元素呈现出不同的变化规律，叶片中磷、钾、镁、硫元素在全年生育期内均呈现先升高再降低的趋势，钙元素含量则随着叶龄增加不断增加，至果实半红期趋于平缓，铁、锰、铜、钼元素含量随叶龄增加波动较大，但总体趋势为先升高再降低；果实中磷、钾、钙、镁、锰、锌、硫、硼元素含量在全年生育期内均表现为坐果期含量较高，而后呈持续降低趋势，而果实中铜元素含量则表现为先升高后降低，钼元素则呈波动性上升趋势。相关分析表明，叶片和果实中的矿质元素含量呈现一定的相关性。
- Abstract:
- Jun jujube were used as a test materials,the annual dynamic changes of the contents of 11 mineral elements in the leaves and fruits were studied,in order to improve the nutritional environment of Jun jujube,improve fruit quality,and provide a theoretical basis for rational fertilization.The results showed that during different growth and development stages of Jun jujube,the mineral elements in the leaves and fruits showed different changes,the phosphorus,potassium,magnesium,and sulfur elements in the leaves gradually increased first and then decreased.The trend was that the content of calcium would increase with the increase of leaf age,and would gradually flatten to the half-red period of fruit.The content of iron,manganese,copper and molybdenum would change and interact with the increase of leaf age,but the overall trend was to increase first and then decrease.The content of elemental phosphorus,potassium,calcium,magnesium,manganese,zinc,sulfur,and boron was constantly changing,showing a higher content at the fruit setting stage,and then it continued to decrease,while the content of copper in the fruit first increased and then correlation analysis showed that the content of mineral elements in leaves and fruits showed a certain correlation.
