Sheep manure was used to prepare biochar under pyrolysis temperature of 600ºC. The structural features of biochar were characterized by elemental analysis, BET analysis and scanning electron microscopy. The effects of pH, biochar dosage, adsorption time, temperature on adsorption of methyl orange (MO) in water by sheep manure biochar, as well as its adsorption mechanism, were investigated via batch...
Accumulation of salts in soils has become a serious environmental threat for plant growth and causes considerable loss in yield. Okra Abelmoschus esculentus L. is an important crop and sensitive to saline stress. In the present study, to explore methods for growing okra in salty area, exogenous gibberellic acid (GA₃) and ascorbic acid (AsA) were foliage applied on okra seedling under NaCl stress....
Changes in the ecosystem structure and ecosystem service value of the Fuping basin of the Daqing River from 1985 to 2015, as ascertained through remote sensing and a value assessment model, respectively, showed that forest land had contributed the most to the total ecosystem service value, followed by cultivated land and grassland. The ecosystem structure had changed markedly, the area under different...
Atrazine is a widely used herbicide, and because of its potential to seriously pollute soil and water resources, has attracted widespread attention. In this study, the bacterial strain LY-1 was isolated and identified as the species Arthrobacter. At present, there are many different atrazine-degrading bacteria that have been screened out, including Arthrobacter sp., Pseudomonas sp., and Shewanella...
We investigated how factors underlying local spatial variations controlled needle litter decomposition across a chronosequence of Chinese pine (Pinus tabuliformis Carr.) forests. Litterbag methods were used to measure changes in litter chemistry and the mass loss of leaf litter, as well as selective biotic and abiotic factors during the growing seasons (May-October) in 2013 and 2014 in a set of fully...
The objective of the study was to evaluate the effects of increasing dietary standardized ileal digestible (SID) lysine (Lys) level on the expression of jejunal amino acids (AAs) transporters and the microflora in the hindgut of weaned pigs. One hundred and twenty weanling pigs weighing 8.10 ± 0.48 kg were randomly assigned according to body weight and sex to 5 treatments with 6 replicates per treatment...
As an environmental factor, light influences the physiological functions and secondary metabolism of plants. However, the role of light in cotton fiber development and pigment biosynthesis has not yet been thoroughly explored. In this study, ovules of green cotton were cultured in vitro under dark and light conditions, and fiber and ovule growth parameters as well as fiber carbohydrate and cellulose...
