The invention relates to the technical field of rice seedling-raising substrates, in particular to a rapid rice seedling-raising substrate and a preparation method thereof. The substrate is made of the following raw materials in parts by weight: 30-50 parts of fermented material, 15-25 parts of vermicompost, 10-30 parts of pond silt, 5-10 parts of volcanic rock, 5-10 parts of vermiculite, 0.02-0.08 A strong seedling agent. The rapid rice seedling raising substrate provided by the invention has a wide range of raw material sources, a simple preparation process and stable quality, which can enable the rice to emerge 1-2 days earlier and meet the requirements of machine transplanting 4-5 days earlier, the seedlings are more tidy and robust, the root system is more developed, and the Supplement organic matter for rice fields. |
