Abstract

The invention discloses a paddy rice seedling breeding matrix, and belongs to the technical field of soilless culture. The full-nutrient paddy rice seedling breeding matrix is prepared from the following raw materials: decomposed organic manure, turf, clay, zeolite powder or bentonite, vermiculite, fine river sand, rice hull powder or corn straw powder or mushroom residue powder, soybean meal, ammonium sulfate, calcium superphosphate, potassium chloride, magnesium sulfate heptahydrate, zinc sulfate heptahydrate, ferrous sulfate heptahydrate, boric acid, copper sulfate pentahydrate, manganese sulfate monohydrate and sodium metasilicate nonahydrate. The full-nutrient paddy rice seedling breeding matrix disclosed by the invention has the advantages of high fertilizer-retaining property and water-retaining property, good air permeability, high buffering, full nutrient and more persistence in fertility, achieves the pH of 5.0-5.5, and is lower in cost by utilizing agricultural wastes, namely rice hulls, corn straws, mushroom residues and the like, suitable for batch production, good in seedling breeding effect and convenient for a farmer to use.

Description

technical field [0001] The invention relates to a seedling-raising substrate, in particular to a full-nutrition paddy dry seedling-raising substrate and a preparation method thereof, belonging to the technical field of soilless cultivation. Background technique [0002] Rice is the most important food crop in my country with a huge planting area. Heilongjiang Province is an important grain production base in my country, with an annual total grain output of nearly 100 billion catties. In recent years, the area of ​​rice in Heilongjiang Province has continued to expand. Since most rice seedlings are raised using dry-raised and sparse-planting techniques, it is necessary to collect a large amount of topsoil of 15-20 cm of high-quality upland cultivated land as seedling bed soil every year. Because Heilongjiang Province is located in a cold temperate zone, the temperature in spring is low, the soil thaws slowly, and it is difficult to obtain soil for rice seedling cultivation. ...
