Using pot experiment, study the L size crosslinked polyacrylamide (L - CPA) and urea with way of banana seedling growth and nitrogen absorption, leaching, residue, apparent loss of n to the influence of reasonable L - CPA in banana seedling stage. The results showed that in the banana seedling stage l-cpa and urea mixture or adsorption and distribution can significantly improve the high and nitrogen uptake of banana seedling stage, respectively, 16.62% and 19.26%, 29.44% and 49.15% respectively. The percentage of nitrogen in plant absorption was increased by 7.58 and 12.65 percentage points respectively, while the apparent loss decreased by 5.72 and 6.16 percentage points respectively. Compared with the application of urea nitrogen, the adsorption of l-cpa and urea could also significantly promote the accumulation of dry matter in banana seedling stage and increase 39.63%. Reduced nitrogen leaching loss by 4.01 percentage points; In addition, the nitrogen absorption and nitrogen content of banana seedling stage were significantly higher than that of urea three times in plant absorption, and 7.41% and 2.65 percentage points respectively. To sum up, in banana seedling with L size crosslinked polyacrylamide with urea, appropriate USES adsorption with, will be more helpful in banana growth, promote the nitrogen absorption use, reducing the loss of nitrogen leaching and apparent, reduce the number of fertilization.
