绿肥对茶园生态系统的影响及其发展对策

目的]探讨绿肥对茶园生态系统的影响,为制定合理的经营管理措施以维持茶园健康持续发展提供理论参考.方法]根据已有的研究文献,探讨与分析绿肥套种对茶园生态系统的影响,分析面临的问题,并提出茶园适宜种植品种及发展对策.结果]绿肥可改善和提升茶园土壤肥力条件、防止茶园水土流失、改善茶园内小气候、调节茶园土壤的温湿度、改善茶叶品质、增加经济收益、提高茶园生态系统稳定性.目前,茶园发展绿肥存在茶农思想上认识不足、绿肥推广渠道不畅通、绿肥的栽培管理和综合利用技术相对缺乏、茶园绿肥新品种选育缓慢、适于茶园种植的绿肥品种单一等问题.建议]应扩大宣传力度、加强绿肥综合利用技术推广力度和适宜绿肥品种的收集与选育等,以推动茶园绿肥的持续发展.

Influence of green manure on ecosystem of tea gardens and strategies for its development

Objective]The present experiment was conducted to investigate the effects of green manure on the ecosystem of tea garden in order to find out reasonable measures for managing tea garden and ensure its sustainability and healthy development.Method]In accordance with previous studies,the impacts of green manure on ecosystem of tea garden and the current issues were analyzed and suitable varieties for tea garden and strategies in its sustainable development were proposed.Result]Green manure was found to bring the following assets to tea garden:soil fertility and microclimate enhancement,soil and water loss prevention,better moisture in soil,better tea quality,more economic benefits and a more steady ecosystem.For the time being,there were a few problems,restricting the use of green manure,such as insufficient knowledge of tea farmers,lesser number of promoting channels,lack of good cultivation practices and their management,and inadequate green manure varieties due to long and slow breeding processes,etc.Suggestion]In order to further promote the application of green manure in tea garden,there should be more publicity,technology extension and more green manure varieties to be used in tea gardens.
