摘要
长期以来农药的不合理利用已经引发了环境污染、食品安全等一系列问题,探索减少农药投入的生产模式,构建稻田生物多样性生态控制病虫害的水稻生产模式已经成为稻田可持续发展的重要手段之一。为了更好地开展海南稻田生物多样性保护、发挥稻田生态系统服务功能,有必要系统全面地了解农民对稻田生物多样性保护认知及农药使用情况,我们在海南北部和南部分别开展了调查。结果显示,调查区大部分稻农对稻田生物多样性概念不了解,相关知识掌握较少,且仅有极少数农民接受过相关的多样性种植培训或者指导。在农药使用上,存在过量使用、盲目使用和跟风使用等一系列不科学问题,直接导致海南稻田生态系统遭到破坏,种植成本骤增,稻农净收益降低。通过分析,就海南水稻生产中的农药使用问题提出了意见和建议。
Improper utilization of pesticide for a long time in China has led to a series of problems such as environmental pollution, food unsafety etc. Exploring the rice production pattern of reducing pesticide usage, building an ecological method for controlling plant diseases and insect pests of rice paddy, has become one of the important means for sustainable development of rice production. In order to better carry out the rice biodiversity conservation and ecosystem services in Hainan, it is necessary to completely and systematically understand the farmers' knowledge and perception about biodiversity conservation and the pesticide use in Hainan paddy field. We launched an investigation in north and south part of Hainan respectively. The result shows that most of the rice farmers don't understand the concept of biodiversity and have less related knowledge about rice ecosystem services, among of them only a few ones have received training or guidance of plant biodiversity. As for the use of pesticide, excessive, blind and aimless use result in the destruction of Hainan rice ecosystem, the increase of rice farming cost and reduction of net income from rice practice. Based on the investigation and analysis, comments and suggestions on pesticide use of Hainan rice production are given in this paper.
