Effects of Continuous Straw Returning on Soil Functional Microorganisms and Microbial Communities

Journal of Microbiology, 2023
This study examined the changes in soil enzymatic activity, microbial carbon source metabolic diversity, and straw decomposition rates in paddy fields treated with 1, 2, or 3 years of straw returning (SR1-SR3). The soil's ability to decompose straw and cellulolytic bacteria increased with the number of treatment years (1: 31.9% vs. 2: 43.9% vs. 3: 51.9%

Design of Straw Guiding Device for Straw Returning Machine

Journal of Industry and Engineering Management
Burying straw into the field is the most direct and effective method for straw utilization. This research enables deep soil fertilization and interval deep loosening. To enhance the efficiency of deep straw burial and returning, as well as the straw cleaning rate, a concave straw guiding device was designed and installed on a side-sweeping type straw ...

Modeling the greenhouse gas budget of straw returning in China

Annals of the New York Academy of Sciences, 2010
Straw returning is considered to be one of the most promising carbon sequestration measures in China's cropland. A compound model, namely “Straw Returning and Burning Model—Expansion” (SRBME), was built to estimate the net mitigation potential, economic benefits, and air pollutant reduction of straw returning.

[Response of Straw and Straw Biochar Returning to Soil Carbon Budget and Its Mechanism].

Huan jing ke xue= Huanjing kexue, 2015
Direct straw returning and straw carbonization returning are the main measures of straw returning. Because of the differences in structure and nature as well as returning process between straw and straw biochar, the soil respiration and soil carbon budget after returning must have significant differences.

Energy and environmental impact assessment of straw return and substitution of straw briquettes for heating coal in rural China

Energy Policy, 2019
Abstract The utilization of straw plays an important role in China's sustainable development. Returning straw to fields as organic fertilizer (straw return) and processing straw into straw briquette fuel (SBF) are two of the most promising methods for employing straw; however, there is a lack of information with respect to comparing these two methods.

Effects of Straw Return on Mitigating Cadmium‐Contaminated Soils

Soil Use and Management
ABSTRACT Cadmium (Cd) contamination of fields has historically been a serious problem for agricultural production in China. Cd can accumulate in plants from the contaminated soil, polluting food and threatening human health. Straw return has proven effective for remediating Cd‐contaminated soil.

Research on Quantitative Methods for Measuring the Spatial Distribution of Straw After Rotary Tillage in Straw Return

Soil Use and Management
ABSTRACT Distribution of straw incorporation in soil is a key indicator of the effectiveness of straw return. Due to the complexity and time consumption of conventional methods, this study employed three image processing techniques—second‐order moments of grey‐scale histogram (HSM), Optimized Area‐weighted ...
