浒苔多糖/魔芋葡苷聚糖/生物质炭肥料地膜的制备
Preparation of Enteromorpha Polysaccharides/Konjac Glucosidan/Biochar Fertilizer Mulch Film
摘要
Abstract
This study extracted Enteromorpha polysaccharide from Enteromorpha,and used urea-loaded biochar(U-BC,loading ratio of 17.8%),Enteromorpha polysaccharide,and konjac glucomannan(KGM)as raw materials to prepare a biodegradable nutrient-functionalized Enteromorpha polysaccharide/KGM/biochar fertilizer mulch film(UBCF).The chemical structure,urea-releasing property,mechanical prop-erties,water resistance,light transmittance,thermal stability,and biodegradability of UBCF were systematically investigated.The results re-vealed that UBCF contained abundant functional groups including hydroxyl,carboxyl,and sulfonic acid groups.The cumulative release ratio of urea in UBCF was 76.9%after 20 h water immersion.Notably,UBCF exhibited light transmittance<3%,meeting the optical require-ments for opaque black films.After 80 days of soil burial,the degradation rate of UBCF reached 68.3%,confirming its excellent light-block-ing capability,biodegradability,and favorable thermal stability.关键词
