摘要
利用DGPS技术在田间定点取样,定点测试土壤养分和性质分布,以形成土壤主要养分分布层图。为合理施肥,节约费用、降低成本奠定基础。通过合理施肥,达到增加粮食产量、提高经济效益、保护生态环境的目的。
Making use of DGPS technology to sample the soil specimens and to monitor the soil ingredients, the distribution of plant foods and the characteristics of soil will be find out. Recur to this, we can make fertilizing rationally and reducing operation costs. When grain yield and ecological environment will both benefit.
