Study of Compatibility of Effective Naphthalene Water-reducing Agent with Ceramic Slurry Billet
Bulletin of the Chinese ceramic society, 2012Co-Authors: Xia QingAbstract:By the use of X-ray diffraction,fluidity and suspended analysis,Zeta-potential and grading measurements.the effects of different types of superplasticizer(effective naphthalene water-reducing agent,Naphthalene and sodium metasilicate,Naphthalene,sodium metasilicate and sodium hexametaphosphate,enterprises to use the Inorganic Compound reducing agent)are mixed separately into the construction ceramic slurry properties.It was studied that how fluidity and suspensibility of kaolin mud,thixotropy and the impact of particle size were affected by different kinds of water reducer and different mechanisms were analyzed.The relative molecular mass and structure of water reducer and content,moisture content and shape of ceramic blank,particle have great impact on their compatibility.Appropriate proportion(including 0.35% sodium metasilicate;0.1% sodium hexametaphosphate;0.05% effective naphthalene water-reducing agent) of mixed water reducer is added into designed ceramic castable according to the compatibility of Inorganic and organic Compound reducing agent,the effect of the slurry to improve performance is superior to a single naphthalene superplasticizer and the Inorganic Compound reducing agent being used in businesses currently.Such as increasing liquidity,reduce pulp moisture,reduce feed slurry particle size,increase the mechanical strength of dry body.

Compound Fertilizer Manufactured from Sediment of West Lake
Agro-environmental Protection, 2001Co-Authors: Zhu BenAbstract:An organic－ Inorganic Compound fertilizer with a ratio of two to eight was produced by mixing sediment of West Lake and chemical fertilizer. Another experiment with Compound fertilizer applied on vegetable soil showed that yield with treatment of organic－ Inorganic Compound fertilizer was equal to or more than that with imported Compound fertilizers under the condition with same nutrient level. In addition, the cost was lower and nitrate content in vegetable was reduced with the organic－ Inorganic Compound fertilizer applied.

Compound fertilizer from chemical fertilizers with sediment of the West Lake and its application in vegetable
The Journal of Agricultural Science, 2000Co-Authors: Zhu BenAbstract:A series of organic Inorganic Compound fertilizer was produced by mixing the sediment of the West Lake and chemical fertilizer in a ratio of two to eight.Results of vegetable experiment showed that vegetable yields of the plots applied the organic Inorganic Compound fertilizer was same to or somewhat higher than those applied abroad Compound fertilizer under the conditions of same nutrient level.Moreover,the cost was cut and the nitrate content of vegetable reduced as application of the sediment Compound fertilizer.

effects of organic Inorganic Compound fertilizer with reduced chemical fertilizer application on crop yields soil biological activity and bacterial community structure in a rice wheat cropping system
Applied Soil Ecology, 2016Co-Authors: Jun Zhao, Zhiying Fang, Qiwei Huang, Ruifu Zhang, Biao Shen, Qirong ShenAbstract:Abstract The development of more stable and sustainable agroecosystems for improving food production has caused wide public concern in recent years. In the present study, we conducted a field experiment to investigate the effect of pig manure organic–Inorganic Compound fertilizer with reduced chemical fertilizer on the crop yields, soil physicochemical properties, biological activities and bacterial community structure in a rice–wheat cropping system over two crop seasons (rice and wheat). The results showed that at all sampling times, this fertilizer regime enhanced the soil nutrient availability, microbial biomass, enzymatic activities, and soil nitrogen processes and, to some extent, promoted crop yields. Across all soil samples, bacterial communities were dominated by Proteobacteria, Acidobacteria, and Chloroflexi at the phylum level. Hierarchical cluster analysis based on the weighted UniFrac distance revealed that the bacterial community structures were strongly separated by the sampling time, and the treatments in the wheat harvest soils. A Venn diagram of shared OTUs showed a core microbiome across different treatments and sampling times, in which the relative abundance of each abundant phylum (class) was stable in the different treatments and at different sampling times. Specifically, the relative abundance of Alphaproteobacteria, Gammaproteobacteria, Nitrospirae, Bacteroidetes, and Actinobacteria was largely and particularly enriched under the organic–Inorganic Compound fertilizer regime, indicating that soil functions, such as nitrification and the turnover of organic matter, might be strengthened under this treatment. Collectively, these results indicate that the application of organic–Inorganic Compound fertilizer may reduce chemical fertilizer use and improve the long-term productivity and sustainability of agroecosystems.

responses of rice wheat rotation system in south jiangsu to organic Inorganic Compound fertilizers
Journal of Applied Ecology, 2011Co-Authors: Hengda Tian, Li Zhang, Jianchao Zhang, Qiujun Wang, Halihashi Yibati, Qiwei HuangAbstract:In 2006-2007, a field trial was conducted to study the effects of applying three kinds of organic-Inorganic Compound fertilizers [rapeseed cake compost plus Inorganic fertilizers (RCC), pig manure compost plus Inorganic fertilizers (PMC), and Chinese medicine residues plus Inorganic fertilizers (CMC)] on the crop growth and nitrogen (N) use efficiency of rice-wheat rotation system in South Jiangsu. Grain yield of wheat and rice in the different fertilization treatments was significantly higher than the control (no fertilization). In treatments RCC, PMC and CMC, the wheat yield was 13.1%, 32.2% and 39.3% lower than that of the NPK Compound fertilizer (CF, 6760 kg x hm(-2)), respectively, but the rice yield (8504-9449 kg x hm(-2)) was significantly higher than that (7919 kg x hm(-2)) of CF, with an increment of 7.4%-19.3%. In wheat season, the aboveground dry mass, N accumulation, and N use efficiency in treatments RCC, PMC, and CMC were lower than those of CF, but in rice season, these parameters were significantly higher than or as the same as CF. In sum, all the test three Compound fertilizers had positive effects on the rice yield and its nitrogen use efficiency in the rice-wheat rotation system, being most significant for RCC.

a theoretical study on the molecular structure and vibrational ft ir and raman spectra of new organic Inorganic Compound n c3h7 4 2sncl6
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2014Co-Authors: Sondes Hajlaoui, I Chaabane, Abderrazak Oueslati, K Guidara, Alain BulouAbstract:Abstract Tetrapropylammoniumchloride was used as a ligand for the synthesis of the new organic–Inorganic Compound bis-tetrapropylammoniumhexachlorostannate. Vibrational study in the solid state was performed by FT-IR of the free Tetrapropylammoniumchloride ligand (TPACL) and by FT-IR and FT-Raman spectroscopies of the [N(C 3 H 7 ) 4 ] 2 SnCl 6 Compound. The comparative analysis of the Infrared spectra of the title Compound with that of the free ligand was discussed. The structure of the [N(C 3 H 7 ) 4 ] 2 SnCl 6 Compound was optimized by density functional theory (DFT) using B3LYP method and shows that the calculated values obtained by B3LYP/LanL2MB basis are in much better agreement with the experimental data than those obtained by B3LYP/LanL2DZ. The vibrational frequencies were evaluated using density functional theory (DFT) with the standard B3LYP/LanL2MB basis, and were scaled using various scale factors. Root mean square (RMS) value was calculated and the small difference between experimental and calculated modes has been interpreted by intermolecular interactions in the crystal.
