Due to the increasing water scarcity and need for sustainable agricultural practices in arid regions, optimizing fertilizer management is crucial enhancing crop productivity resource efficiency. Field experiments 2022 2023 northwestern China’s region explored impacts of irrigation volume, organic use, their coupling on pumpkin yield, quality, water-fertilizer The study included ten treatments with a completely randomized two-factor design, comprising three quotas, application rates control group (CK). results showed that significantly enhanced soil moisture content, which peaked at depth 50 cm. Irrigation quota had highly significant impact vine length stem diameter (P < 0.01), interaction between two factors 0.05). rate dry matter accumulation 60 ~ 80 days after sowing, trend F2 > F3 F1 identical quota. effects use efficiency (IWUE), partial (PFP) quality were statistically 0.01). Specifically, volume from W1 W3 increased yield by 17.36%. However, initially then decreased response application. IWUE increase application, while PFP volume.

Seasonal drought and summer soil high-temperature stress in Southern China often lead to decreased yield quality of Annona squamosa. It is important explore reasonable effective water fertilizer management measures as well cover improve the hydrothermal conditions orchards realize increase This study involved a two-year (2022–2023) field experiment Yun County, Lincang City, Yunnan Province, using three factors three-level orthogonal test, resulting nine different experimental treatments for water, heat. The irrigation levels were W1 (soil moisture content 55% capacity), W2 75% capacity) W3 85% capacity). F1 (1666 kg·hm−2), F2 (2083 kg·hm−2) F3 (2500 methods A1 (no cover), A2 (fresh grass cover) A3 (straw cover). effects these on conditions, growth indices fruit s1uamosa systematically monitored analyzed, relationships between was analyzed based Mantel test. results showed that T5 (W2F2A3) had highest average over two years, followed by T7 (W3F1A3). (W3F1A3) treatment effectively reduced temperature 5 °C compared T1 (W1F1A1). with an 33.99% Additionally, has soluble solids, sugars vitamin C increases 28.13%, 13.36% 4.86%, respectively, A Pearson correlation analysis there significant squamosa temperature, test influence yield. comprehensive benefit promoting growth, increasing improving plant. quantities, amounts coupling interaction status root zone, investigated, providing reliable theoretical support scientific planting model low-heat river valley Province.
