蔗叶还田对土壤理化性状、生态环境及甘蔗产量的影响

Effect of Trash Returning on Physical and Chemical Properties of Soil, Ecological Environment and Yields of Sugarcane

蔗叶中含有大量甘蔗所必须的碳、氮、磷、钾及其他微量元素,是一种数量多、可就地利用的优质有机肥源。蔗叶还田是缓解当前有机肥源不足的一项有效措施,也是增加土壤有机物和保持土壤生产力的重要途径,合理利用这部分资源对蔗糖产业的可持续性发展具有重要的现实意义。针对国内外蔗叶还田技术的生态效应及对土壤性状和甘蔗产量的影响方面做一综合阐述。基于我国蔗叶还田的研究现状,指出应加强蔗叶还田长期定位监测试验,在建立监测数据库和不同技术标准、农机农艺结合及新型农机研发、病虫草害综合防治等方面需进一步开展系统、深入的研究。

Sugarcane leaves contained a considerable of essential nutrients, including carbon, nitrogen, phosphorus, potassium and other micronutrients. Sugarcane leaves was great quantity and could be made good use of organic fertilizer to return field. Trash returning was the effective measurement that mitigated organic fertilizer shortage in soil and was also an important method that could increase soil organic matter and maintain soil productivity. Rational utilization of sugarcane leaves had practical significance to the sustainable development of sugar industry. This paper reviewed the sugarcane leaves returning to field at home and abroad on the ecological effects, soil properties and sugarcane yield. According to the research status of sugarcane leaves returning to field in China, there were some aspects should be further researched on the effect of long-term sugarcane leaves returning to field on soil properties, establishing of monitoring databases and different technical standards, developing the new technology of new agricultural machinery and it combining sugarcane agronomy and developing integrated control for insect pests, disease and weeds.
