| 摘 要： | 利用全膜覆盖垄作技术在高原山旱地种植马铃薯,取得了显著的蓄水、保墒、增温以及增产效果,是山旱区农业增效和农民增收的一项重要措施。本文结合全膜覆盖种植马铃薯在施肥技术方面存在的问题,结合生产实际提出了以调控氮肥为主和使用缓释氮肥配合磷、钾肥播前一次性施入,达到补充后期氮素的需要,以获得高产高效的目标。

| Abstract: | Plastic cover ridge technology in the mountain dry land cultivation potatoes has made significant effect in water storage,soil moisture,warming,and the yield,it is an important measure on agricultural efficiency and rural incomes in the mountain arid areas.In this paper,the fertilization problems on the whole film cover cultivation potatoes combine production actual need for the regulation of nitrogen and slow release nitrogen fertilizer with phosphorus,potash fertilizer was applied before one-time broadcast reach supplementary late nitrogen in order to obtainhigh productivity and efficiency goals. |
