Abstract

The invention discloses an all-energy product for raising rice seedlings in cold regions, which comprises 40-60 parts of puffed rice husks; 30-40 parts of fermented fungus slag; 10-30 parts of fermented straw; and 5-10 parts of vermiculite. The preparation method comprises step a, selecting rice husks for extrusion and puffing. Step b, fully mix the puffed rice husk obtained in step a with fertilizer and fungicide and let stand. Step c, performing aerobic fermentation on the fungus residue and the straw respectively. Add sulfuric acid to the products of step d and step c to adjust the pH. Step e, mixing the products in step b and step d, adding vermiculite to the mixture, adjusting the pH with sulfuric acid solution, and finally mixing to make the materials fully mixed. Step f, the product of step e is sieved and bagged to leave the factory. The various components of this all-energy formula combine nutrients, growth environment, disease prevention and other elements into a homogeneous, all-round, safe, efficient, and easy-to-operate seedling carrier, which completely solves various problems in conventional seedling raising with guest soil + seedling strengthening agent , increase rice yield.

Description

technical field [0001] The invention relates to the field of rice seedling cultivation and cultivation, in particular to an all-energy substance for rice seedling cultivation in cold regions and a preparation method thereof. Background technique [0002] In my country, the rice area north of 40 degrees north latitude is usually called the cold area rice cultivation area. Heilongjiang Province is located in the northernmost part of my country and is one of the high latitude rice areas in the world. The rice planting area is 44°20ˊ18.44~50° north latitude 15ˊ1.01, belongs to the cold area rice cultivation area. The characteristics of rice growth in cold regions are short growth days, less active accumulated temperature, slow warming in the early stage, short high temperature time in the middle stage, rapid cooling in the late stage, and more cold damage from low temperature. [0003] Rice is the main crop in Heilongjiang Province. In order to overcome climate disadvantages and...
