瓦斯灰微量元素肥料是炼钢高炉渣的副产物(又叫钢渣微肥)。据测定:它含钼、锌、锰、铜、铁等10多种元素。在我国晋、豫、浙、鄂、湘、京等省、市科研单位多年试验结果,瓦斯微肥对许多农作物施后有促进生长发育的良好效果,目前正在扩大示范推广之中。为充分挖掘江西省新余市钢铁基弛的这一资源优势,促进农业生产的发展,增强农业活力,我们于1989～1990年开设了瓦斯微肥在棉花上作种肥的合理施用量试验的应用研究课题,现将情况小结如下。
Gas ash trace element fertilizer is a by-product of blast furnace slag (also known as steel slag fertilizer). It is measured: it contains molybdenum, zinc, manganese, copper, iron and other 10 kinds of elements. In our country, Henan, Zhejiang, Hubei, Hunan, Beijing and other provinces, municipalities and scientific research units for many years test results, many of the crop gas fertilizer to promote the growth and development of good results, is currently expanding demonstration and promotion. In order to fully exploit this resource advantage of Xiju Steel in Xinyu City of Jiangxi Province, promote the development of agricultural production and enhance the vitality of agriculture, we started to apply the rational application rate test of nitrogenous fertilizer on cotton in 1989 ~ 1990 Research topics, the situation is summarized as follows.
