The invention provides a special high-efficiency weeding striking root fertilizer for paddy rice. The fertilizer is prepared from the following components by weight: 55 to 65 parts of a nitrogen fertilizer, 4 to 6 parts of sea mud, 0.5 to 1.5 parts of tobacco, 1.5 to 2.5 parts of a selenium-rich additive, 1 to 2 parts of a herbicide, 1 to 2 parts of pig bone, 15 to 25 parts of straw powder, 0.5 to 1.5 parts of red yeast, 0.4 to 1 part of compound sodium nitrophenolate, 1 to 2 parts of tea residue, 4 to 6 parts of potassium fulvate, 0.4 to 1 part of shell powder, 1 to 2 parts of waste dreg of pleurotus eryngii, 1 to 2 parts of olive residue, 1 to 2 parts of zinc sulfate, 1.5 to 2.5 parts of modified corn starch and 0.2 to 0.4 part of fennel powder. The fertilizer has weeding rate of more than 95%, and the green-returning rate of paddy rice in 3 d reaches 100%; the fertilizer has strong fast dissolving capability and can be dissolved within 10 min; a fertilized paddy rice plant is strong, has a great number of tillers and plump grains and can realize yield increase and income increase; and rice cultivated by using the fertilizer contains organic selenium easily absorbable by the human body and has the advantages of edible safety and high biological efficiency.
