Given the abundant straw resources in Northeast China and the huge external costs associated with fossil fuels, straw-based biomass power plants have emerged as a popular alternative to coal-fired power plants. The sustainability of these green alternatives depends on straw supply from farmers, yet little is known about their perceptions regarding such supply because of a lack of cooperation in...

The present investigation highlights the feasibility of a polymer grafting process to enhance the durability and flame retardancy of rice straw towards application as a low cost roofing material. The success of this grafting methodology was perceived to depend upon a bi-step pre-treatment process encompassing delignification and inorganic salts dispersion. Subsequently free radical polymer graf...

With the exception of the phloem and the crown of the parenchyma, which borders the medullary lacuna, the walls of the tissues of both treated and untreated straw were lignified. The walls of the treated straw were not fluorescent in the ultraviolet probably because the treatment had modified the phenolic acids. They also had a stronger reaction to Schiff reagent particularly in the sclerenchym...

The aim of this study was to investigate the influence of reaction temperature and wheat straw moisture content on the pyrolysis product yields, in the temperature range of 475-575 °C. Samples of straw with moisture contents from 1.5 wt % to 15.0 wt % were fed to a bench scale Pyrolysis Centrifuge Reactor (PCR). The experimental results show that the changes in straw moisture content have no si...

Swine (Sus scrofa) slurry stored in open storages is a source of airborne contaminants. A customary practice for ammonia and odor control consists of covering the surface of the slurry with floating materials, such as straw. Although straw covers have been proven to generally reduce gaseous emissions, more knowledge is needed regarding how age, moisture content, and microbiological development ...

A rice straw - cellulose utilizing mold was isolated from rotted rice straw residues. The efficient rice straw degrading microorganism was identified as Trichoderma reesei. The results showed that different carbon sources in liquid culture such as rice straw, carboxymethyl cellulose, filter paper, sugar cane bagasse, cotton stalk and banana stalk induced T. reesei cellulase production whereas g...

Some Basidiomycota were chosen for studies of key ligninases synthesis (25°C, 30 days) in modified medium (shaken or not cultures) with added wheat straw. Liquid Czapek medium with straw yielded a higher amount of laccase than peroxidase, ground straw induced enzyme worse than chopped straw. With peroxidase the reverse dependencies were observed. Laccase of Lentinus edodes synthesized two enzym...

Zinc (Zn) deficiency is a well-documented worldwide problem for crops and humans. Although phosphorus (P) fertilizer application achieves high grain yield in intensive agricultural systems, it can reduce Zn availability cereal grains. Therefore, quantitative evaluation of the P–Zn antagonism needed. A global meta-analysis 51 publications with wheat, maize, rice was performed to quantitatively a...

Natural disasters have a major detrimental impact on agricultural production. In recent decades, China has experienced more frequent natural as result of climate change. Although the spatial and temporal changes in for individual catastrophic activities are well understood, several cereal crop productivity subsequent quality loss remains unknown. Furthermore, due to key significance China’s dai...

Environmentally safe ways are sought to prevent the accumulation and accelerate degradation of herbicide active substances in agricultural soil. This study aimed determine effectiveness finely-ground barley straw bentonite mitigating effects soil contamination with Successor T 550 SE. was applied following doses: 0, 0.73, 14.63 mg substance per kg. The spring were used at 10 g/kg. action these ...
