富硒农业生长气候条件分析及产品硒含量测定

Analysis on climatic conditions of Se-enrich crop growth and determination of Se-content in products

利用博山区大监站、区域站和土壤水分站的气象资料,分析了富硒农作物生长所需的气候条件及其生育过程中的主要气象灾害。农产品和土壤硒含量检测,为作物硒肥控制提供技术支持。结果表明:(1)博山区雨热同季、光照充足、无霜期较长,发展富硒农业气候资源丰富,但降水变率大,不同程度地限制了光、热资源的有效利用,应加快小型水利设施建设,实现适时浇灌。(2)富硒作物生长过程中易受低温冷冻、暴雨大风、冰雹等灾害性天气的影响较大。(3)现代农业区和东南部生态区,大部分为足硒土壤,需要施用硒肥,应注重富硒农业的技术规范和合理管理,为北方低硒地区发展富硒农业提供科学依据。

The climatic conditions required for the growth of selenium-enriched crops and the main meteorological disasters in the process of fertility were analyzed by using meteorological data of Boshan district monitoring stations,regional station and soil water station.Agricultural products and soil selenium content detection,for the control of crop selenium to provide technical support.The results show that:(1)Boshan area is rich in rain inhot season,also with abundant light and long frost-free period.The development of rich selenium agriculture is rich in climate resources,buteffective using of the light and heat resources limited by the variable precipitation rate,the construction of small water conservancy facilities should be accelerated to achieve timely watering.(2) Rich selenium crop growth process vulnerable to low temperature freezing,heavy rain,hail and other severe weather effects.(3) In modern agricultural area and southeastern ecological zone,adequate selenium content of the soil in most areas,which need to apply selenium fertilizer.Should focus on the technical specifications and rational management of selenium-rich agriculture,and provide scientific basis for the development of selenium-rich agriculture in the northern low-selenium area.
