The invention relates to a special fertilizer for green selenium-rich capsella bursa-pastoris cultivation. The special fertilizer is prepared from the following components by weight: 40-60 parts of humus soil, 15-25 parts of beer lees,0.4-0.6 part of amino acids, 4-6 parts of sodium selenite, 1.5-2.5 parts of soybean meal, 15-25 parts of a ternary composite fertilizer, 4-6 parts of capsicum annuum leaf ash, 4-6 parts of selenium-rich yeast, 4-6 parts of urea, 4-6 parts of seaweed mud, 1.5-2.5 parts of tea leaf ash, 4-6 parts of purple sweet potato powder, 4-6 parts of selenium-rich tea residue, 4-6 parts of peanut bud powder, 4-6 parts of bee pollen powder, 4-6 parts of a soil conditioner, 1.5-2.5 parts of corn peptide, 4-6 parts of white tea powder, 4-6 parts of a soil bactericide, 10-20 parts of organic matter, 1.5-2.5 parts of bone powder, and 4-6 parts of violet arenaceous mud. According to the present invention, the preparation method is simple, the cost is low, the soil bactericide is added so as to effectively kill bacteria in soil, rapid plant rooting and no disease generation can be ensured, and the survival rate is improved; and the planted capsella bursa-pastoris has characteristics of health, no toxicity, safe eating, and rich nutrition.
