| Abstract: | According to the evaluation of daily absorption of nitrogen, phosphorus and potassium quantity and uptaking intensity ratios winter wheat with high yield , nitrogen nutrient critical stage came in wheat tillering stage, and the same stage of phosphorus and potassium appeared ahead of wheat reviving stage; the highest efficiency of nitrogen absorption was in booting-ripening stage, that of phosphorus and potassium was after wheat jointing stage. |
