Abstract

The present invention discloses a seedling raising matrix, and particularly relates to an enzyme type dryland-raised rice seedling matrix and a preparation method thereof, and belongs to the technical field of soilless culture. The enzyme type dryland-raised rice seedling matrix is prepared from the following raw materials by mass: 25-30 parts of an enzyme organic fertilizer, 15-20 parts of peat, 20-30 parts of clay or topsoil, 15 parts of fine river sand or crushed perlite, 10 parts of rice husk powder, 2.26 parts of ammonium sulfate, 65 parts of calcium superphosphate, 0.65 part of potassium chloride, and 0.0283 part of zinc sulfate heptahydrate.

Description

technical field [0001] The invention relates to a seedling-raising substrate, in particular to an enzyme-type rice seedling-raising substrate and a preparation method thereof, belonging to the technical field of soilless cultivation. Background technique [0002] Rice is an important food crop in my country, with a huge planting area of ​​about 438 million mu. Since most rice seedlings are raised using dry-raised sparse planting techniques, a large amount of topsoil of 15-20 cm of high-quality upland cultivated land needs to be collected as seedling bed soil every year. The topsoil of high-quality cultivated land is taken away, resulting in a serious loss of cultivated land resources. Seedbed soil extraction will also cause serious ecological problems such as soil desertification and soil erosion. Using soil to grow seedlings, soil-borne diseases, weed hazards, and secondary saline-alkali hazards still threaten the quality of seedlings at all times, and the technical requir...
