Effects Of Long-Term Application Of Chlorine- And Sulfur-Containing Fertilizers On Soil Properties

dina L-(+)-Ergothioneine, Uncategorized

Keywords

Fertilizer, Chlorine, Sulfur, Soil Properties

Abstract

26-year long-term positioning experiment was conducted in red soil rice fields in Qiyang, Hunan. The results showed that continuous application of chlorine- and sulfur-containing fertilizers, especially sulfur-containing fertilizers, for many years will cause soil acidification. Cl- is easily lost with water, and long-term continuous application will not leave a large amount of residue in the soil; while long-term application of sulfur-containing fertilizers, SO2-4 has obvious accumulation in the topsoil and subsoil layers, and the accumulated SO2-4 changes the soil properties. Chemical properties have a significant impact on rice growth.

Ergosterol, Yeast, Extraction, Crystallization

Abstract

Using Saccharomyces cerevisiae dry yeast as raw material, in an appropriate amount of methanol and potassium hydroxide solution, saponify and reflux in a water bath at 95°C for 2.5 hours, extract ergosterol with organic solvent ether, and concentrate and enrich under reduced pressure. Slowly cool down to crystallize at 4 to -7°C to obtain crude ergosterol with a yield of 1.11%. Dissolve crude ergosterol in diethyl ether solvent and recrystallize to obtain higher purity ergosterol crystals. The average yield is 0.69% and the extraction rate can reach 62.58%. A scanning electron microscope was used to observe the crystal morphology of the crystals obtained by constant temperature crystallization and cooling crystallization, and infrared spectroscopy was used to characterize the structure of ergosterol.

Programmed Temperature Combustion, Sulfur Fixation, Catalytic Combustion

Abstract

Using programmed temperature combustion reaction technology, the effects of kaolin composite CaO, Fe2O3-CaO, and CoO-CaO additives on anthracite coal combustion and sulfur fixation were investigated. Experiments have found that these added substances all have a promoting effect on the combustion of coal cracking products. Except for the Fe2O3-CaO-kaolin composite additive, which has a certain hindering effect on the combustion of coal char, the rest have a promoting effect on the combustion of coal char, especially The effect of CoO-CaO-kaolin composite additive is the most significant. Kaolin composite calcium sulfate should have high thermal stability, but it is decomposed by the reduction of coal char and CO at high temperatures. Therefore, cobalt oxide, which has an obvious catalytic combustion effect on coal char, is added to reduce the reducing atmosphere and stabilize the product. Calcium sulfate products are produced to promote sulfur fixation.

Sulfur Behavior Soil Atmosphere Plants

Abstract

This article explains the sulfur content of soil, the main forms of sulfur, the yield-increasing effect of sulfur fertilizer in agricultural ecosystems, the main sources and behaviors of sulfur compounds in the atmosphere, compensation to ecosystems, and the harm to plants of excessive concentrations. It was pointed out that the soil sulfur content status varies between regions and soil types, the availability of soil sulfur forms to plants is significantly different, and the demand for soil sulfur by plants varies greatly. The main sources of sulfur in the atmospheric environment are natural sources such as volcanic eruptions and artificial sources released by the burning of sulfur-containing fuels (such as coal). There is an exchange and balance of sulfur between the plant ecosystem and the atmospheric environment. Atmospheric SO2, at a certain concentration It has an important compensatory effect on the ecosystem. If the concentration is too high, it will have a series of adverse effects on plant growth and physiological responses.

Abstract

This study used greenhouse sand cultivation experiments to examine the effects of different concentrations of Mn, Zn and Fe treatments on the contents of lysergic acid amide and ergonovine in the endophytic fungus symbiont of Drunk Horsegrass, in order to clarify the content of the three trace elements required for the symbiont to produce alkali. optimal concentration range. The results show that: (1) Under short-term (3 weeks) treatment, the contents of symbionts lysergic acid amide and ergonovine reached the maximum when the Mn2+ concentration was 5.0 mmol·L-1, and were significantly higher than the rest of the Mn2+ concentration gradient; Under longer-term treatment (6, 9 weeks), the lysergic acid amide content was the largest when the Mn2+ concentration was 5.0 mmol·L-1, but the increase was not obvious. Ergonovine accumulated under the control (0.01 mmol·L-1Mn2+) treatment. The amount reached the maximum and was significantly higher than that of the other treatments. (2) When the treatment time was 3, 6 and 9 weeks, the symbiont lysergic acid content reached the maximum value at 7.0 mmol·L-1 in the Zn2+ treatment, and the content in the 3-week treatment was significantly higher than that in the other treatment times; its ergot New base reached the maximum value when the Zn2+ concentration was 21.0 mmol·L-1 under the three treatment times. (3) Under different treatment times, the content of symbiont lysergic acid reached the maximum value at Fe concentration of 6.0-12.0 mmol·L-1, and the content at 3 weeks was significantly higher than that at other treatment times; ergonovine The content reached the maximum value at the Fe concentration of 0 mmol·L-1 in the 3rd and 6th weeks, and reached the maximum value at the Fe concentration of 0.03 mmol·L-1 in the 9th week. Studies have shown that high concentrations of Mn, Zn and Fe elements for a short period of time are beneficial to stimulating the accumulation of two types of ergot alkaloids in the endophytic fungal symbiont of Drunken Horsegrass. This can be improved by controlling the concentrations of the three trace elements and the growth time of the symbiont. The contents of the two ergot alkaloids provide more precise external conditions for extracting higher concentrations of lysergic acid amide and ergonovine as clinical agents or biopesticides in the future.

Indirect Determination Of Bupivacaine Hydrochloride By Atomic Absorption Spectrometry

dina L-(+)-Ergothioneine, Uncategorized

Keywords

Bupivacaine Hydrochloride, Atomic Absorption Spectrometry, N,N-Dimethylformamide, Stripping

Abstract

It was proposed that the ion pair association formed between bupivacaine hydrochloride and cobalt thiocyanate was extracted with dichloroethane in the presence of N,N-dimethylformate (DMF). After back-extraction, atomic absorption was used to extract A new method to indirectly determine the content of bupivacaine hydrochloride by measuring the amount of Co2+ in the stripping solution using spectrometry. This method shows a good linear relationship (r=0.9999) in the range of 0.05-1.30g/L, and the recovery rate is in the range of 98%-103%. Used in actual sample measurements to obtain good results.

Effects Of Combined Application Of Sulfur And Silicon On Soil Copper Forms And Copper Absorption By Rice

dina L-(+)-Ergothioneine, Uncategorized

Keywords

Rice, Sulfur, Silicon, Copper, Form

Abstract

Copper is one of the main heavy metal pollutants in farmland in Jiangxi Province. In order to reduce and control the harm of copper to rice growth and improve rice yield and quality, pot experiments were conducted to study different sulfur fertilizers (0, 30, 60, 90kg·hm-2 , calculated as S) and silicon fertilizer (0, 0.5, 1.0, 1.5g·kg-1, calculated as Si) effects on copper absorption by rice and soil copper forms. The results show: (1) The application of sulfur and silicon fertilizers in copper-polluted farmland can reduce the content of acid-extractable Cu in the soil and increase the content of residual Cu, but soil iron-manganese oxide-bound Cu and organic matter/sulfide The content of bound Cu varies depending on the dosage of sulfur and silicon; (2) Each sulfur and silicon treatment can reduce the absorption of copper in stems, leaves, and brown rice by promoting the accumulation of copper in rice roots or reducing the content of available Cu in the soil. accumulation. From the impact on copper content and yield in brown rice, it can be seen that the sulfur dosage of 30kg·hm-2 and the silicon dosage of 1.0g·kg-1 have the best interaction effect, and have application prospects in production.
