| 摘 要： | 寒地水稻高产施肥技术应以"前重、中轻、后补"为原则,根据叶龄进程及叶色变化施肥.今后要增施硅肥,由三元(氮磷钾)施肥逐渐向四元(氮磷钾硅)转变.在计划施肥量不变的情况下,施肥后移.

| Abstract: | The fertilizer for high yield rice production in cold region should be based on the principle which"early days more,midterm less and later period supplemented",applied the fertilizer according to the progress of leaf age and the change of leaf color.From now on,adding silicon fertilizer was necessary and the pattern of fertilizer application should be changed from three elements(N,P,and K) to four elements(N,P,K and Si).In the circumstance of no change of planning amount,the period of fertilizer application should be postponed. |
