Effects of Different Treatment of Potassium on High Yield of Wheat on Ground Part and Dynamics of Potassium in Soil

The paper adopted the farmland experiments with different indoor analytical method of potassium to high yield of wheat and soils that the wheat grows in the period in the potass accumulated plant dynamics state variety characteristics.The result expressed that the different period in the wheat, total trend of potassium accumulation is that before slow-moving rising, the middle attained the high peak,then descend , different level had the different dissimilarity to the plant.In the soil the accumulation of available potassiume and slow released potassium in the whole period in the wheat is complicated because of the fertilizer, the farm crop assimilation, the temperature, the precipitation and the state of the water in the soil.The performance is that under the different treatment of potassium in the soil with available potassiume and slow released potassium in the whole process that wheat grow, always keeping the tallest level with the K3, then K2, the K1 is minimal.
