摘要
根据精准农业变量投入的技术要求,研制成功国产变量施肥播种机。该播种机由变量控制器控制机械式无级变速器,根据GPS的位置信号,完成处方图设计的播种施肥作业。通过对播种机的静止和地块工作试验可知,变量施肥控制可靠,变量数据记录正常,播种作业效果良好。
On the demand of precision agriculture of variable rate input technology, the homemade combined seed and fertilizer drill were successful manufactured. It could be accomplished sowing work prescribing by the application maps based on the GPS signal under the control of mechanical variable speed unit. We knew from the static and working testing that the control of variable rate fertilization was credible, the presented variable rate data was normal and the working condition of fertilization was satisfactory.
