| Abstract: |
| In order to optimize the planting and management of Annona squamosa L. in the dry\|hot valley area, this study conducted experiments in A.squamosa orchards in Lijiang Town, Yuanjiang County, Yunnan Province, from 2023 to 2024. The three\|factor and three\|level orthogonal experimental design of irrigation amount, fertilizer amount, and dissolved oxygen amount was adopted, and a total of 9 treatment combinations were set up to explore the effects of different water\|fertilizer\|gas coupling treatments on the growth, yield, and quality of A.squamosa, and the optimal treatment scheme was screened out by the comprehensive evaluation method combined with analytic hierarchy process (AHP) and TOPSIS model. The results showed that irrigation amount, fertilizer amount, and dissolved oxygen amount had significant effects on leaf area, net photosynthetic rate, fruit longitudinal diameter, single fruit weight, single plant yield, vitamin C content, soluble total sugar, and soluble solid content of A.squamosa. Among them, the W3F2O1 treatment (high irrigation volume, medium fertilization volume, and low dissolved oxygen volume) performed best in increasing leaf area, single fruit weight, and single plant yield,while the W2F3O1 treatment (medium irrigation volume, high fertilization volume, and low dissolved oxygen volume) was significantly effective in increasing vitamin C content and total soluble sugar content. Through the AHP-TOPSIS comprehensive evaluation, the W3F2O1 treatment had the highest comprehensive score, indicating that it had the best comprehensive promotion effect on the growth, yield and quality of A.squamosa. This study successfully constructed a comprehensive evaluation system for the coupling effect of water, fertilizer, and gas on A.squamosa, and recommended the W3F2O1 treatment as the optimal solution for high\|yield cultivation of A.squamosa and the W2F3O1 treatment as the optimal solution for high\|quality cultivation. At the same time, it provides a theoretical basis and scientific support for the precise regulation of water, fertilizer, and gas to achieve high\|quality and high\|efficiency production of sugar apple in dry\|hot valley areas. |
