The invention discloses a special agricultural ferment for northeast ecological rice seedling culture. The special agricultural ferment comprises raw materials for preparing the agricultural ferment for seedling culture, chemical components of the agricultural ferment, preparation methods and conditions of the agricultural ferment, and a use method of the agricultural ferment for seedling culture,wherein the raw materials for preparing the agricultural ferment for seedling culture adopt full plant raw materials and additives. The special agricultural ferment is prepared by taking pure plant materials as base materials; adding sugar and trace elements; and fermenting fruit with pectin and green plants separately. With the adoption of the special agricultural ferment, the seed germination rate can be increased, the diseases carried by seeds can be inhibited, and a chemical rooting agent can be replaced; the seedlings can grow healthily, the immunity is improved, and the seedlings can beendowed with the higher capacity of resisting environmental pressure; the seedlings can grow normally in an unideal soil condition, and a basis for healthy seedling transplanting is supplied; and thespecial agricultural ferment has the advantages of being recyclable, efficient, environmentally-friendly and sustainable in development, keeping soil health, and continuously improving soil fertility.
