The invention discloses an ecological fertilization method for facilitating yellowing and maturity of honghuadajinyuan tobacco leaves. The ecological fertilization method includes the steps of returning straws to a field, using an active agent to cushion a pond, performing combined application of residue fertilizers, covering the pond with farmyard manure and dressing potash fertilizer, and particularly includes the steps of chopping the crop straws, and spreading the chopped crop straws in tobacco furrows row by row uniformly to enable the crop straws to be deeply buried at the roots of tobacco plants; mixing a disease resisting agent with a functional organic fertilizer to obtain a mixture, applying the mixture to the positions, close to the bottom of the pond, in the pond; performing uniform hole application of a compound nitrogen-phosphorus-potassium fertilizer and a middle-micro fertilizer in the positions, close to the upper middle portion of the pond, in the pond; applying a decayed farmyard manure on the most superficial layers of tobacco ridges uniformly in a spread manner after transplanting of the tobacco plants; topdressing the potash fertilizer to the roots of the tobacco plants, and applying the potash fertilizer on the front sides and the back sides of upper middle leaves of the tobacco plants in a spraying manner, wherein the usage amount of the crop straws is 400-1000kg/mu, the usage amount of the disease resisting agent is 0.5-2.5kg/mu, the usage amount of the functional organic fertilizer is 20-50kg/mu, the usage amount of the compound nitrogen-phosphorus-potassium fertilizer is 0.5-6.5kg/mu, the usage amount of the middle-micro fertilizer is 0.5-3.0kg/mu, the usage amount of the decayed farmyard manure is 500-1000kg/mu, the usage amount of the potash fertilizer for the roots of the tobacco plants is 10-14kg/mu, and the usage amount of the potash fertilizer for the leaves of the tobacco plants is 1-3kg/mu. The ecological fertilization method is capable of balancing soil fertility, improving soil quality, preventing nematodes from harming the tobacco plants and facilitating normal growth, maturity and yellowing of the tobacco plants positively.
