Development and application of comprehensive utilization technologies of sugarcane tip in China
Being one major by-product of sugarcane industry,sugarcane tip is a high-quality renewable resource with large yield and rich nutritional ingredients.However,the comprehensive utilization rate of sugarcane tip in China is very low,and the high value-added products are few,thus fails to give full play to its advantage of high-quality resources.Therefore,the nutritional and fertilizer characteristics of sugarcane tip were summarized,and the development progress and application of current main comprehensive utilization technologies of sugarcane tip in China were introduced in de-tails,including preparing ruminant feed,being used as boiler fuel,raw material for extracting nutritional or active ingre-dients,as well as being returned to the field after chopping,preparing beverage and fertilizer with high content of humic substance,and the key bottlenecks existing of these technologies were also analyzed.For example,most feed were rougha-ge with low nutritional value resulted in very low economic benefit;lacking of key theories and technology for boiler fuel;an potential increase of pest and diseases of sugarcane resulted from being returned to the field as fertilizer;lacking suitable clarification methods for large-scale production of sugarcane tip beverage and low extraction rate of active or func-tional ingredients.At the same time,the new emerging comprehensive utilization technologies of sugarcane tip in China,including being Chinese herbal medicine,livestock and poultry breeding fermented mattress material and aquatic animal feed,preparing activated carbon and other functional materials,were also introduced in this paper.It is concluded that the development of sugarcane tip leaves in China should be combined with the main development trend of sugar industry and the development needs of related industries,and focus on key theory research and technology upgrade in improving the preparation of fermented protein feeds,fertilizers with high humic substance content,traditional Chinese herbal medi-cine,activated charcoal and its functional materials as well as functional substance extraction,and accelerate the promo-tion and application of these techniques.At the same time,the development of new comprehensive utilization technology of sugarcane tips should be strengthened,and a new application way of sugarcane tips can be created,which lays a theo-retical foundation or provides technical support for the early realization of high-end utilization of sugarcane tips in China
