摘要
棉花秸秆是棉花生产的主要副产物,其含有丰富的木质素、纤维素和半纤维素以及粗蛋白等物质,是一种重要的可再生的生物质能源,可广泛用于农畜业、工业、能源、环保等领域,具有极高的开发利用潜力。为了开发出成熟实用的棉秆综合利用技术,找到棉花秸秆综合利用的产业化、工业化和市场化最佳途径,最终实现经济效益、环境效益和社会效益的多方共赢。笔者通过查阅资料和调研,总结了“目前我国对棉花秸秆的利用途径单一、低效,造成了巨大的资源浪费和严重的环境污染”等棉花秸秆利用的实际情况,概述了棉花秸秆还田和离田利用的主要途径,分析了各项途径中存在的关键问题,提出了“开发棉花秸秆离田多元化新型利用途径,深入挖掘棉秆综合利用潜力,提高棉秆资源综合利用效率,最终提高植棉效益”的棉花秸秆利用策略。
Cotton straw is the main by-product of cotton production,which is rich in lignin,cellulose and hemicellulose,crude protein and other substances.It is an important renewable biomass energy,which can be widely used in agriculture and livestock,industry,energy,environmental protection and other fields,and has a very high development and utilization potential.In order to develop the mature and practical cotton comprehensive utilization technologies,implement the optimal way of industrialization,industrialization and marketization in comprehensive utilization of straw,finally realizes the economic benefit,environmental benefit and social benefit win-win basis,based on investigation and the reference of many related documents,the author came to the conclusion of the actual situation of cotton stalks utilization who says that the utilization of cotton straw is simple and inefficient,resulting in huge waste of resources and serious environmental pollution.Furthermore,the author outlined the main ways of cotton straw returning or leaving the field,and analyzed the key problems existing in various ways.Ultimately,the author came up with the best strategy of cotton straw comprehensive utilization says that development of the new diversified utilization way of cotton straw from the field can deeply tap the comprehensive utilization potential of cotton straw,improve the comprehensive utilization efficiency of cotton straw resources,and finally improve the efficiency of cotton planting.
