河北坝上高原错季无公害蔬菜生产的环境标准与技术

The Environmental standard and technique of non-pollution vegetables production in staggered season in the region of Bashang plateau of Hebei province

着重论述了河北坝上高原错季无公害蔬菜生产的环境标准与技术问题。针对人们对农产品安全质量与环境标准的要求,简要介绍了无公害蔬菜生产绿色食品、有机食品的基本概念;明确了河北省坝上地区无公害蔬菜生产的地理区位优势:气候冷凉,光照充足,雨热同季,昼夜温差大等,并指出该区存在的干旱多风少雨等主要问题;进而提出坝上错季无公害蔬菜生产的环境标准与技术:限量施用纯氮≤225kg·hm-2和有机肥≤75000kg·hm-2等措施。这些对我国入世后加强农产品安全质量与环境质量管理,推行无公害绿色食品生产体系与技术指标,确保农业可持续发展均具有重要指导意义。

This paper deals with the problems of the environmental standard and technique of nonpollution and staggered season vegetables in the region of Bashang plateau in Hebei Province, and introduced the basic concept of nonpollution vegetables, green foods and organic foods, in which explicited the superiority of geographical seat, as that cold climate, sufficient illuminition, hot and rainy season in the same term, the temperature was greatly different between day and night etc, but the few rainfall and arid of weather mainly existed problems about production of the nonpollution vegetables in the region of Bashang plateau. In the paper, the environmental standard and technique was put forward to produce the staggered season vegetable of nonpollution. The highest quantity of pure nitrogen fertilizer is limited to 225 kg·hm-2 and the organic manure set bounds to 75 000 kg·hm-2 in the region. So there is an important meaning to enhance the management with the safe quantity in agriculture products and environmental quantity. At the same time it is also helpful to make the system of producing green foods and nonpollution foods, so that ensured the sustainable development of agriculture.
