Hainan Island is the most important tropical fruit production area in China. In this study, 372 soil samples and corresponding irrigation water were collected from orchards analysed to determine concentrations of six heavy metal(loid)s: Cd, Hg, As, Pb, Cr, Cu. The pollution status, potential risks, possible sources, spatial distribution patterns metal(loid)s comprehensively investigated. had negligible amounts metal(loid)s, human health risk for consumers was at a safe level. metal(loid) lower than national screening values. However, significant local accumulation especially Cu, relative their background values observed. Moreover, combined effects only led mild level low ecological throughout study area. Noncarcinogenic risks not observed among residents, carcinogenic within an acceptable range. acidic increased Cd pollution, organic matter affected tested soil. Uncommon geogenic sources with high Cr anthropogenic activities primarily As contamination, combination natural responsible Hg emissions. research suggested that appropriate strategies must be implemented track reduce metal contaminants northern western region orchard results can provide valuable information policies on prevention management, environment, protection region.

In the transitional region between agriculture and livestock rearing in northern China, planting forage crops rows among fruit trees as feed orchards represents an effective strategy for enhancing ecological environment while addressing increasing demand feed. Nonetheless, impact of short-term mowing cover on quality soil remains unclear. A two-year field experiment was conducted Ziziphus jujuba cv. “Lingwuchangzao” located Lingwu County, Ningxia Hui Autonomous Region, arid semi-arid Northwest China. The consisted four treatments: (A) clean tillage (CK), (B) plantation with Lolium perenne (LP), (C) Trifolium repens (TR), (D) Vicia villosa (VV).The results showed that intercropping may lead to a reduction most nutrients Z. orchards, particularly 0–20 cm layer. However, TR can mitigate this declining trend even enhance nutrient levels within 0–40 depth. Furthermore, had more pronounced effect α-diversity fungal communities than bacterial communities. This practice also altered relative abundance genera such Sphingomonas, Bacillus, Flavobacterium 20–40 depth dominant Fusarium Mortierella effects physicochemical properties were significant those communities.These indicate China have varying impacts depending type crop used.

Orchards are complex agricultural systems with various characteristics that influence crop evapotranspiration (ETc), such as variety, tree height, planting density, irrigation methods, and inter-row management. The preservation of biodiversity improvement soil fertility have become important goals in modern orchard Consequently, the traditional approach to weed control between rows, which relies on herbicides mobilization, has gradually been replaced by use permanent living mulch (LM). This study explored potential a remote sensing (RS)-assisted method monitor water productivity apple orchards mulch. experimental data were obtained Lis Valley Irrigation District, Central Coast Portugal, where “Maçã de Alcobaça” (Alcobaça apple) is produced. methodology was applied over three growing seasons (2019–2021), combining ground observations RS tools, including drone flights satellite images. estimation ETa followed modified version Food Agriculture Organization United Nations (FAO) single coefficient approach, (Kc) derived from normalized difference vegetation index (NDVI) calculated images incorporated into daily balance. average seasonal (FAO-56) 824 ± 14 mm, (WP) 3.99 0.7 kg m−3.

In this study, the effects of natural grass cultivation and clear on physiological characteristics Korla fragrant pear during fruit development storage were investigated, providing a scientific basis for high-quality cultivation. Sugar components, enzyme activities, gene expression levels in pulp peel comprehensively analyzed storage. A classification model was constructed using machine learning algorithms (RF, KNN, SVM), particle swarm optimization (PSO) employed to identify key factors. The results showed that significantly enhanced sugar accumulation fruits, particularly at 120 150 days after flowering, with fructose content increasing by 9.09 mg·g−1 12.59 mg·g−1, respectively, glucose also rising significantly. Additionally, promoted relative GK, PFK, FK genes pulp. During storage, activities group consistently higher than those across different periods, PFK activity being 23.73 U/L identified glyceraldehyde kinase, phosphofructokinase, fructokinase as factors influencing content. significant negative correlation observed between phosphofructokinase content, though relationship requires further investigation. This study elucidates regulatory mechanism which methods affect quality through photosynthetic product distribution. Our findings provide critical foundation are expected advance efficient industry, helping farmers improve both income.
