【摘要】 本文总结了几年来沙坡头地区沙障麦草防腐的研究结果。在沙障麦草致腐的因素及沙障麦草防腐效果的考核方面,均取得了有益的进展。通过试验发现不同年龄沙障麦草中的纤维素递增、碱抽出量的递减规律与红松相反;而木质素变化基本不大,与燕麦杆、玉米秸腐烂中木质素递增规律相近。该地区沙障麦草的腐烂变质,除与其化学成份密切相关外,还受制于自然腐蚀与微生物噬食的交互作用。本文还介绍了优选出的9种高效、安全防腐剂及其易于推广使用的防腐方法。更多还原

【Abstract】 This paper summed up the research results on the preservation of wheat straw usedin checkerboard barrier includin grotting factors of wheat straw and the anti-rot effectiveness, which were conducted in Shapotou Area of Tengger desertfor several years. Field experiments showed that cellulose contents of diffe-rent aged straw and extracts of alkali liquor were progressively increased anddecreased respectively, this is contrary to the experimental results of red pine.Nevertheless, the lignin has little changes, being similar with oat and cornstraws, of which lignin was progressively increaced during rotting processes.Besides they have a close relation to chemical composition, the rot and degr-adation of wheat straw can also be affected by the interaction of naturalcorrosion and microbe decomposition. Nine effective and safe preservativesselected were described in the paper.更多还原
