Research and Application Progress of Straw

Abstract

Straw is a general term for the stem and leaf parts of mature crops, and is a multi-purpose renewable biomass energy resource in the agricultural ecosystem. The prospect of comprehensive utilization of straw has become broad with the development of agricultural production, the advancement of science and technology, and the improvement of the level of agricultural mechanization. The comprehensive utilization of straw plays an important role in enhancing the sustainable development ability of agricultural economy and improving the current situation of comprehensive utilization of agricultural resources in my country. This paper briefly combs the development history of straw and the prospect and current situation of comprehensive utilization, and expounds the separation technology of straw components, straw man-made panels, straw concrete, straw returning technology and oyster mushroom cultivation. It focuses on the description of the component separation technology of straw and the manufacturing process of straw-based panels. The different separation methods and separation effects of cellulose, hemicellulose and lignin were introduced in detail, and the static yield strength (MOR), internal bonding strength (IB) and water absorption thickness of several common straw-based panels were compared and studied (TS). Finally, it summarizes the benefit analysis of the comprehensive utilization of straw by scholars from the perspective of economics, and summarizes the corresponding measures based on their own views.

Understanding the drying mechanism of straw substrate culture block: Physicochemical properties, pore structure, and drying optimization

“…Half of the photosynthesis products in crops are allocated to seeds, while the other half is present in straw, which refers to the fibrous plant residue remaining after seed harvest. As a renewable biomass resource, Straw holds significant quantities and serves various purposes [ 1 ]. The issue of straw utilization has garnered public attention in recent years, as its proper usage is closely linked to environmental factors such as air quality, global nitrogen and carbon cycles, agricultural productivity, and sustainable development [ 2 ].…”

Research Progress on Anaerobic Digestion of Cellulose Waste Based on Bibliometric Analysis

“…According to the International Rice Research Institute, an average of 0.7-1.4 kg of rice straw waste is generated for every 1 kg of rice produced [2]. Average annual production of agricultural straw reaches 1.14 billion tons [3]. Cellulose waste is a huge biomass resource when disposed of rationally [4].…”
