Utilizing gamma rays as an initiating agent, a simultaneous irradiation method was applied to graft acrylic acid and acrylamide onto corn straw that had been decrystallized using NaOH/urea solution at reduced temperature, aiming fabricate superabsorbent polymer gel (SAPG) capable of absorbing significantly more water. The structural attributes the straw, SAPG were analyzed via Fourier transform infrared spectroscopy (FTIR), X-ray crystal powder diffraction (XRD), thermogravimetric analysis (TG), scanning electron microscopy (SEM). To enhance SAPG’s performance, optimization various parameters carried out, such dose, dose rate, ratio monomer proportion (AA) (Am), degree neutralization. resulting exhibited distilled water absorption 1033 g/g 90 in 0.9 wt.% NaCl solution, with radiation 5 kGy, rate 1.5 kGy/h, AA-to-AM mass 1.2, monomer-to-CS 7, 90% AA

Plastic film-bottomed treatment (FBT) is a critical agricultural practice in arid regions, aimed at enhancing crop productivity by improving soil moisture retention and nutrient availability. However, the effects of different depths (DFBT) on nitrogen (N) absorption translocation spring wheat remain inadequately understood. We conducted field experiment sandy to investigate DFBT (60, 70, 80, 90, 100 cm) total N amount (TNAA), (TNTA) all nutritive organs, grain content (GN), yield (GY). Morphological measurements included GY, GN, TNAA, TNTA stem, sheath, leaf, spike axis, kernel husk (SAKH), culm. The results showed that FBT significantly reduced loss, with cm depth reducing leakage 59.6% (p < 0.001). At flowering stage, derived from fertilizer (NDF) (NDS) were higher 80 maturity, (TNAA) main stem across organs under 0.001), leading improved use efficiency. correlation between GN was strongest Grain (GY) optimized intermediate depths, particularly cm, suggesting this provides an optimal balance water drainage These findings underscore importance optimizing depth, achieve enhanced retention, efficient utilization, systems. This research insights into sustainable practices water-limited conditions, offering practical guidance for food security regions.

As an important branch of ancient Chinese silk dyeing and printing technology, alkali degumming utilizes agents to degum raw silk, creating differences in fiber water absorption, dye uptake, optical characteristics between degummed non-degummed areas achieve localized pattern formation.Based on the processes Silk Gauze using alkaline boiling, steaming, gel, this study compares effects these three techniques under different conditions agent dosage, hot press temperature, duration. The efficiency, surface morphology, infrared spectra were analyzed compared. Through analysis mechanisms, it was found that within a micro-system, meets alkali, water, heat required for precise Gauze. Combining dual boiling gel can rapid at temperature 80 °C 50 s, without significantly affecting morphology or primary structure implementation holds significant importance expanding application traditional modern processes.
