To reduce the preparation cost of superabsorbent and improve N release rate at same time, a novel low-cost (SA) with function slow was prepared by chemical synthesis neutralized acrylic acid (AA), urea, potassium persulfate (KPS), N, N'-methylenebis(acrylamide) (MBA). The order influence factors on water absorbency property determined an orthogonal L18(3)7 experiment. On basis optimization results experiment, effects single factor absorption were investigated, highest (909 g/g) achieved for...
The effects of newly developed controlled release urea (CRU) and its placement method on the N use efficiency nutritional quality winter wheat ( Triticum aestivum L.) grown a loam soil were investigated during 2 yr. was soil. CRU applied at 0, 75, 150, 225 kg ha −1 with seeds sowing while treatment split into two applications: two‐thirds one‐third 5‐tiller stage (Z25). Results showed that rates fit requirements improved wheat's apparent uptake by 28.5% compared to treatment. Although 150 had...
Although commercialized slow-release fertilizers coated with petrochemical polymers have revolutionarily promoted agricultural production, more research should be devoted to developing superhydrophobic biopolymer coatings superb ability from sustainable and ecofriendly biomaterials. To inform the development of biopolymer-coated (SBSF), mechanism SBSF needs clarified. Here, superior performance, water tolerance, good feasibility for large-scale production was self-assembly fabricated using a...
In this work, lignite, a low-grade coal, was modified using the solid-phase activation method with aid of Pd/CeO2 nanoparticle catalyst to improve its pore structure and nutrient absorption. Results indicate that adsorption ability activated lignite NO3-, NH4+, H2PO4-, K+ significantly higher than raw lignite. The successfully combined polymeric slow-release fertilizer, which exhibits typical behavior, prepare super large granular fertilizer (SAF). addition ability, SAF showed excellent...
Soil, air, and water pollution caused by lignite is considered a serious environmental problem. Activation methods thus have been developed to extract humic acid from support the agricultural production as soil amendment or fertilizer synergist. The traditional activation of lignite, however, are not environmentally friendly. As first study, this work novel solid-phase method with Pd/CeO2 nanocatalyst for lignite-derived acid. This study analyzed morphology structures as-synthesized various...
To improve fertilizer use efficiency, reduce irrigation requirement, and minimize negative environmental impact, a novel large-grained-activated-lignite-slow-release (LAF) with good water retention was developed by mechanical extrusion of activated lignite conventional fertilizer. A 3D molybdate-sulfur hierarchical hollow nanosphere (3D-MoS2–HN) catalyst successfully fabricated via simple route, the 3D-MoS2–HN to increase its water-soluble humic acid content nutrient adsorption ability....
Bio-based polyurethanes are promising for the controlled release of nutrients and fertilizers, but their toughness plasticity need to be improved. We developed a smooth, dense, elastic, indestructible bio-based polyurethane (BPU) coating with nutrient ∼150% superior, tensile strength ∼300% higher, ∼1200% higher than those original BPU coating. Through one-step reaction soybean oil polyols (accounting more 60%), isocyanate, benzil dioxime, dynamic covalent network based on oxime-carbamate...
Controlled-release urea (CRU) and its placement method in rice production were investigated during 2007 2008 seasons. was applied at 62.5, 125, 187.5 kg nitrogen (N) ha−1, the N ha−1. All CRU treatments to nursery beds once, they brought into paddy field transplanting, while treatment split three applications from plowing harvest. The results showed that seedlings with CRUs germinated grow well there no salt damage stage. 125 ha−1 had 33% less than (187.50 ha−1), but it produced...
Although solid-phase activation of lignite using a nanocatalyst has great potential in producing low-cost and sustainable humic acid, the large-scale application this technology still faces challenges because high price toxicity nanocatalyst. Additionally, specific molecular components acid activated remain unknown. In work, multifunctional molybdate-phosphorus hierarchical hollow nanosphere (Mo-P-HH) catalyst was successfully manufactured by simple way followed phosphorization. comparison...
Iron (Fe) chelated by water-soluble humic substances can effectively overcome plant micronutrient deficiencies. However, the traditional synthesis methods are often complex, expensive, and thus not applicable to large-scale industrial productions. In this work, an ecofriendly multifunctional Fe–humic acid (HA) complex was successfully prepared through simply ball milling lignite with double-shelled Fe–N hollow mesoporous carbon microspheres (DS–Fe–N–HC). The novel DS–Fe–N–HC synthesized...

There will be great damage in the process of harvesting, transporting, and storing after grain matures. The injury rate is as high 8% to 12%. After damage, germination becomes lower, quality decreases, it easily infected with pests molds. This study grain-crushing characteristics significance ensure quality, an accurate crushing model a prerequisite for effectively simulating characteristics. paper studies shattering wheat grains. Two-dimensional slices were obtained using X-ray tomography...
AbstractOne pot experiment was conducted to study the effects of a new polymeric slow release fertilizer (PRF) on Chinese cabbage growth and soil nutrients. The comprised three kinds (common compound fertilizer, 21% 45% solubility PRF in 25°C water, all fertilizers with N:P2O5:K2O = 10:5.7:20) levels (0, 21.6 43.2 g m−2). Results showed that high water-soluble PRFs (PRFHH PRFHL) fit nutrient requirements cabbage, fertilization level significantly increased yield improved quality cabbage....
