摘要：

研究叶面喷施不同浓度光碳核肥对石榴各生育时期叶片中矿质元素含量变化的影响，确定石榴合理施肥时间和用量，为石榴的科学精准施肥和优质丰产提供理论依据。在云南省永胜县以‘突尼斯’软籽石榴为材料，在常规施肥的基础上研究不同浓度光碳核肥处理(1.3%、1%、0.7%、0.5%)下石榴生育期内叶片矿质元素变化规律。随着石榴生长发育，石榴叶片中N、P、Ca、Zn元素含量呈现上升趋势，K、Mg、Fe元素含量呈现下降趋势。1.3%处理抑制了石榴叶片中N、P的含量；0.7%处理对石榴叶片N、P、K含量有明显的促进作用，较对照（清水喷施）分别提高了22.3%、47.6%、121.9%，且显著提高了石榴成熟期叶片Fe含量；0.5%处理石榴叶片Ca、Zn含量显著增加，最高分别为19.72、144.54 g/kg，较对照分别增加了5%、1.05倍，同时对石榴营养生长期叶片P、K含量有一定促进作用。可以通过叶面喷施一定浓度光碳核肥调控石榴叶片中矿质元素的含量，其中喷施浓度0.7%处理能显著提高石榴叶片N、P、K、Fe含量，0.5%处理对Ca、Zn、P、K含量的提高有促进作用，可根据不同生育时期矿质元素含量的差异制定合适的施肥方案，满足石榴生长发育的营养需求，从而改善石榴品质。

Abstract:

The effects of foliar application of different concentrations of CO2 capture agent on the changes of mineral elements in pomegranate leaves at different growth stages were studied, and the reasonable fertilization time and dosage were determined to provide a theoretical basis for precise fertilization and high quality and high yield production of pomegranate. ‘Tunisia’ soft-seed pomegranate in Yongsheng County of Yunnan Province was used as the material. On the basis of conventional fertilization, the changes of mineral elements in leaves during pomegranate growth under different concentrations of CO2 capture agent (1.3%, 1%, 0.7% and 0.5%) were studied. With the growth and development of pomegranate, the content of N, P, Ca and Zn in leaves showed an upward trend, and the content of K, Mg and Fe showed a downward trend. 1.3% treatment of foliar spraying inhibited the content of N and P in pomegranate leaves. 0.7% treatment had significant promotion effect on the content of N, P and K in pomegranate leaves, which increased by 22.3%, 47.6% and 121.9% respectively compared with those of the control (water spraying), and significantly increased Fe content of mature pomegranate leaves. The content of Ca and Zn in pomegranate leaves treated with 0.5% concentration of CO2 capture agent were significantly increased, and the highest was 19.72 and 144.54 g/kg respectively, increased by 5% and 1.05 times compared with those of the control. At the same time, 0.5% treatment promoted the content of P and K in pomegranate leaves during vegetative growth period. The content of mineral elements in pomegranate leaves can be regulated by spraying a certain concentration of CO2 capture agent on the leaves. Among them, 0.7% treatment of foliar spraying can significantly increase the content of N, P, K and Fe in pomegranate leaves. 0.5% treatment can increase the content of Ca, Zn, P and K. Appropriate fertilization schemes can be formulated according to the differences in mineral element content at different growth stages to meet the nutritional requirement of pomegranate growth and development, thereby improving the quality of pomegranate.
