In order to study the effects of different irrigation amounts on root characteristics and yield cotton without film mulching (abbreviated as filmless cotton) under drip in Southern Xinjiang, five (300, 375, 450, 525 600 mm, represented by W1, W2, W3, W4 W5) one amount with filmed (450 WCK) were set. The length density (RLD), surface area (RSA), average diameter (RAD), volume (RV), weight (RED) analyzed. results two-year experiment showed following: (1) indexes growth reached maximum at flowering bolling stage, soil periphery (30 cm from main root) lower layer (40–60 layer) peak stages, respectively; (2) value index film-free each treatment was W2 > W3 W5 W1. RLD increased 19.41–106.67% 13.66–84.22% peripheral layer, proportion RSA middle (20–40 1.64–3.41% 0.49–4.09% compared other treatments. RAD, RV RWD after relatively large various distribution points soil, followed treatment; (3) WCK not significantly those but smallest, only 29.18–66.84% non-film treatment, while (0–20 surrounding larger, an increase 11.43–102.17% 29.60–111.57%, respectively, (4) seed highest reaching 4833.25 kg·hm−2, still than that 27.79%. Conclusion: An appropriate water deficit is conducive increases uniformity its layer. 375–450 mm for Xinjiang can promote growth, prevent senescence yield, which be used a reference production.

Abstract Water resource shortage has become an important factor limiting agricultural sustainability in China. In addition, the development and utilization of unconventional water resources are greatly for alleviating deficit. The Pakchoi was cultivated by using surface soil (0–20 cm) from field this pot experiment. experiment lasted approximately 1 month to study microbial community structure variation under brackish reclaimed irrigation. 16S rDNA high-throughput assays revealed that bacteria mainly consisted Proteobacteria Actinobacteria at Phylum level, along with Arenimonas Nocardioides Genus level mixed irrigation water. summary, pure promoted part communities inhibited growth activities certain communities. We found improved diversity compared response irrigation, while decreased fresh

Abstract Scientists, environmentalists, and farmers are currently in pursuit of sustainable agricultural practices that can effectively ensure global food security while simultaneously mitigating environmental degradation. A field experiment was conducted to elucidate the impact low-cost capacitance soil moisture-based sensors on lettuce ( Lactuca sativa L.) irrigation water conservation, agro-physiological aspects, nutritional characteristics. The also involved use five different types mulching films: white geotextile (WGup), green (GGup), black plastic (BPup), for both above below ground (WGup-down), (GGup-down), addition un-mulched (control). findings demonstrated application WGup, BPup, WGup&down, GGup&down resulted a significant improvement with WGup exhibiting highest savings at 41.86%, control group exhibited least amount 19.87%. Moreover, productivity levels were observed plants mulched GGup&down, reaching 47,944.68 kg ha −1 , whereas lowest recorded GGup 22,377.89 . In terms (IWP), order effectiveness BPup > GGup-down WGup-down Control, achieving IWP 60.19 m −3 treatment reporting 27.80 percentage applied crop evapotranspiration (Irc) showed saved water, saving only 19.87%, best achieved 41.86%. Additionally, higher nutrients (N, P, Ca, Mg, Fe, Mn, Zn), ascorbic acid (AsA), total phenol content (TPC), showing lower nitrate leaves compared non-mulched plants. Overall, utilization biodegradable films has proven be highly effective low cost by 16.633 US$ year enhance productivity, growth performance, quality, overall crops, thereby contributing sustainability production arid regions.

The purpose of this study was to observe the changes in soil nitrogen pools (active organic and inorganic fractions) after applying materials under drip irrigation with film mulching a semi-arid soil. two-year field experiment included four fertilization treatments: maize straw, fodder grass, sheep manure, control treatment no material applied (CK). results showed that application straw manure significantly increased total content by 9.02~13.33% 11.02~17.27%, respectively, while significant improvement found use grass. Compared CK, returning active pools, except for ammonium content. Meanwhile, particulate 42.11~78.85% materials, which took highest proportion sensitive treatments. Among three most. In conclusion, both are optimum could be improving storage within areas.

Abstract The North China Plain plays an important role in China's crop cultivation regions, with the wheat‐maize rotation serving as predominant cropping system. Nonetheless, a dearth of research refers to impact tillage and fertilizer employment on soil quality (SQ) this region. In study, primary objective centered utilizing index (SQI) derived from both minimum total datasets (MDS, TDS) by linear nonlinear scoring criteria assess SQ. results indicated that there was significant correlation between yield SQI, revealing association key parameters such bulk density, porosity, phosphorus, alkali‐hydrolyzed nitrogen, available phosphorus cation exchange capacity at 0–60 cm layer. study identifies substantially elevated SQI mean values were completely under T8 whose 0.980 (linear), 0.672 (nonlinear) MDS 0.908 0.701 TDS 20–40 cm. Importantly, annual yields highest when maximum. Furthermore, SQ levels within locale demonstrate moderate highly favorable status, ultimately underscoring area's propitious conditions for cultivation. This provides indispensable theoretical guidance agricultural practitioners offers foundational framework supporting enhanced local grain crops.
