从1985年开始,我们马三家劳动教养院进行了水稻两化栽培开发研究,把合理施肥列为重要研究课题,积极开展施肥试验,筛选优化施肥方法。通过大面积示范验证,目前在水稻施肥上已形成体系,现介绍如下。 一、增施农肥,培肥地力 诸多研究资料证明,土壤肥力对农作物产量的贡献大于施用的肥料。这一结论为培肥土壤提高地力,提供了依据。我院从80年代初即开
Since 1985, we have conducted three studies on the cultivation and development of rice in three labor camps in the country. The rational application of fertilizers has been listed as an important research topic. Fertilization experiments have been actively carried out to screen and optimize fertilization methods. Through large-scale demonstration validation, the current system of rice fertilization has been formed, are presented below. First, the additional fertilizer, fertility and fertility Many research data show that the contribution of soil fertility to crop yield is greater than the applied fertilizer. This conclusion provides the basis for soil fertility improvement. Our hospital is open from the early 80s
