Moso bamboo (Phyllostachys pubescens) has an extremely fast growth rate and major carbon sequestration potential. However, little information is available on the dynamics of soil C accumulation fungi communities related to different management practices. Here, we investigated changes in organic (SOC) fractions fungal a plantation under three practices (M0: undisturbed; M1: extensively managed; M2: intensively managed). Compared with M0, SOC levels were reduced by 41.2% 71.5% M1 M2,...
Abstract The enantioselective degradation of quizalofop‐ethyl and its metabolite quizalofop‐acid in two soils, a Wuhan acidic soil Baoding alkaline soil, was investigated. dissipation consisted phases, rapidly deceasing first phase that lasted 1 day slowly decreasing second extended till the end incubation. It is shown S ‐quizalofop‐ethyl degraded slightly faster than R soils. Further incubation enantiopure enaniomers showed configurationally stable soil. Quizalofop‐acid produced quickly,...
In order to establish the effect of cut tobacco drying on subsequent pyrolysis and combustion properties, an oven method was applied treatment samples in a temperature range from 70 170°C. Thermogravimetric analysis used study weight loss behavior dried under N2 air atmospheres. The routine chemical components were also determined with standard methods. results showed that prepared uniformly treated samples. Low-temperature (at 110°C) had little but high-temperature 150 170°C) led...
Abstract Background During the biomass-to-bio-oil conversion process, many studies focus on studying association between biomass and bio-products using near-infrared spectra (NIR) chemical analysis methods. However, characterization of pyrolysis behaviors thermogravimetric (TGA) with support vector machine (SVM) algorithm has not been reported. In this study, tobacco was chosen as object for biomass, because cigarette smoke (including water, tar, gases) released by reactions decides sensory...
Bamboo can be used in the phytoremediation of heavy metal pollution. However, characteristics bamboo rhizosphere archaeal community Cr-contaminated soil under field conditions remain unclear.
Heavy metal pollution in soil is a major global issue, and one effective method for addressing it phytoremediation through bamboo planting. Nevertheless, there notable gap our knowledge as no studies have explored the characteristics of organic matter (SOM) bacterial communities forests during remediation process. To bridge this gap, we conducted research to investigate impact different planting patterns on SOM microbial soils contaminated with heavy metals. The contents dissolved (DOM)...
To clarify the interactions among bio-oil components during pyrolysis, gas- and liquid-phase were decoupled investigated, respectively. In this study, was separated into aromatic-rich fraction aromatic-poor fraction, these two fractions pyrolyzed in a quartz basket with baffle at bottom to eliminate interactions. The results showed that gas-phase promoted coke formation via cross-polymerization between light compounds aromatic pyrolysis 300–400 °C tar yields content of aromatics decreased...
On- and off-year management practices are usually adopted in Moso bamboo (Phyllostachys edulis) forests to achieve higher productivity. However, little is known about the effects of these on soil C sequestration microbial community structure. In present study, nutrient content, organic fractions, bacterial fungal communities were comparatively investigated on- stands. The results showed that (SOC), alkali-hydrolyzable N (AN), available P (AP) on-year significantly lower (p ≤ 0.05) than those...
Smoking is a big public health issue because of the harmful substances generated. To diminish risk smoking, cut tobacco was washed with pure water, aqueous solution sodium carbonate, or citric acid to remove precursors in this work. The composition and pyrolysis kinetics were determined interpret reduction generated during fast process. Sugar alkaloid removed partly prewash Thermogravimetric analysis demonstrated that pyrolyzed at higher temperature, while one carbonate lower temperature....
Rotary dryers are commonly used in the modern large-scale tobacco drying industry that consumes huge amounts of energy. In fact, rotary chemical general. It is difficult to investigate behavior at industrial scale. A "differential" laboratory dryer was therefore designed and tested. The large diameter preserved, but width a section dryer. characteristics cut from top leaves bottom with initial moisture contents (22.5 ± 1.0% on wet basis) were studied air temperatures 65, 85, 105, 125, 145°C,...
Permethrin (PM), cypermethrin (CP), and cyfluthrin (CF) are three important synthetic pyrethroids, which contain two, four, four enantiomeric pairs (diastereomers) thus have eight, eight stereoisomers, respectively. In this study, the stereo- enantioselective degradation of PM, CP, CF in a Shijiazhuang alkaline yellow soil Wuhan acidic red were studied detail by combination achiral chiral high-performance liquid chromatography (HPLC). The results showed that degraded faster than soil,...
Root-associated bacteria play a major role in plant health and productivity. However, how organic amendment influences root-associated is uncertain Lei bamboo (Phyllostachys praecox) plantations. Here, we compared the rhizosphere endophytic microbiomes two plantations with (IMS) without (TMS) application of for 16 years. The results showed IMS significantly increased (p < 0.05) relative abundance Proteobacteria decreased Acidobacteria, Bacteroidetes, Verrucomicrobiota. root Acidobacteria...
Phosphorus (P) is a key nutrient in forest ecosystems subtropical regions. However, the effects of long-term application organic amendments on P availability are poorly understood. Here, we compared soil fractions and associated properties southern Chinese Lei bamboo plantations using both an intensive management system (IMS) traditional (TMS). The results show that IMS significantly (p < 0.05) increased total carbon (C), ammonium N (NH4-N), P, available potassium content; microbial...
A new image retrieval algorithm based on color of blocks and moment invariant was presented. First all, the is converted to HSV space, then separated into sub-blocks, it gets histogram in each block as feature. Meanwhile, uses seven HU eccentricity describe shape Finally, similarity calculated invariant. Experiment results show this method very effective.
