The nitrogen content of rice seedlings was related to their ability to resist injury. The nitrogen fertilizer applied excessively, the seedlings grew green and green, and the ability to resist the injury of the plant was weakened. The mechanical transplanted rice seedlings caused more planting injury to the seedlings than the artificial rice transplanting. Therefore, the cultivation of transplanting seedlings should increase carbonitriding of seedlings and reduce the amount of nitrogen fertilizer, so as to improve the seedlings' resistance to injury. In general, soils with higher fertility do not fertilize. Soil with fertile soil can use basal fertilizer (7.5kg per mu).
