棉花生产水肥管理及辅助决策体系研究

水分和养分是棉花生产中最重要的两大投入要素.多年来,棉花生产中主要依靠肥水的大量投入来提高产量,不合理的灌水施肥不仅造成水资源和肥料的浪费,还造成农作物品质下降,环境污染加剧等不良影响.为了寻求合理的水肥投入,对施肥制度、灌溉制度和水肥一体化管理技术进行了探讨,并在此基础上初步构建起棉花水肥管理的辅助决策体系,为下一步建立棉花生产水肥管理决策支持系统,服务于棉花生产打下了基础.

Research on Cotton Production Management of Water and Fertilizer and Assistant Decision Support System

Water and fertilizer are the most important factors which are input into cotton production.Over the years,cotton production mainly relies on the large number of fertilizer and water inputs to increase production.Unreasonable inputs of water and fertilizer not only caused a waste of water and fertilizer,but also caused decline in the quality of crops,increasing environmental pollution and other adverse effects.In order to find a reasonable input of water and fertilizer,irrigation systems and integrated management of water and fertilizer techniques were discussed in this paper.And based on this,a cotton management decision support system,foundation for the establishment water and fertilizer management decision support system of cotton,and serves for the cotton production were built.
