赣南水土保持型果业发展模式探讨

针对江西赣南果业开发中普遍存在的严重水土流失、土地利用率低下、短期效益少等问题，采取以间、套种草、饲、经济作物为主要手段的水土保持措施，栽种“百喜草”，设置“山边沟”，引入美国籽粒苋发展养殖业，开展立体经营，形成果-苋-猪-沼-果良性循环。实现了果园综合效益的同步增长，达到了增加果园植被覆盖度，提高土地利用率，改善果园生态环境的目的。研究表明:果业开发中出现的严重水土流失现象不容忽视，因地制宜的水土流失治理措施与果园生态环境、经济效益密切相关。其综合经营的多种治理模式促进了各业的发展，取得了明显的生态、经

The Exploration of Developing Fruit Industry Mode with Soil and Water Conservation in South Jiangxi Area

In developing fruit business in southern Jiangxi province, the prevailing problems concerning severe soil erosion, low utilization ratio of land, and less benefit in a short time should be solved. Interplanting with grass, forage and economic crops is a main measure of water and soil conservation. By means of planting Paspalum notatum, designing "hillside ditches", introducing grain amaranth from America, developing breeding and multi-management, a good circle of fruit-amaranth-pigs-marsh-fruit has been formed; comprehensive benefits of orchards have been gained; the coverage of orchards has been increased; the utilization ratio of land has been raised and the ecological environment of orchards has been improved. The studies note that the phenomenon of severe soil erosion in developing fruit estate should not be neglected. And the control of water loss and soil erosion with local conditions and the ecological environment of orchards should be considered when the financial benefit is gained. It is the model of multi-management and comprehensive management that has boomed every field of work and has gained obvious benefits of ecology, economy and society and is an effective way of lasting the land of orchards as well.
