Method for sugarcane spica seed sprouting and sprouted seedling temporary-planting

The invention relates to a method for sugarcane spica seed sprouting and sprouted seedling temporary-planting. The method comprises the steps of (1) taking a clear water paper base as a matrix for sugarcane spica seed sprouting; (2) preparing a seedling temporary-planting matrix; (3) carrying out temporary-planting; and (4) after temporary-planting for 15-25 days, crushing a nitrogen-phosphorus-potassium mixed fertilizer in which the proportion of nitrogen to phosphorus to potassium is 10: 10: 15 by grinding, adding water to prepare a nutrient solution, applying the nutrient solution with the concentration of 0.1-0.3 percent once every 5-7 days till the seedlings grow to be above 30cm, planting the seedlings in a field and stopping fertilizing, and carrying out leaf-cutting on the seedlings for 2-3 times in the planting period, wherein in the leaf-cutting process, loosed leaves and a part which is above 2cm away from the leaf center of each seedling are cut off so as to promote seedling and root robustness an
