Abstract

The invention discloses a cold region rice seedling growing multi-potential medium. The medium comprises 40-60 parts of expanded rice husk, 30-40 parts of fermented mushroom dreg, 10-30 parts of fermented straw and 5-10 parts of vermiculite. A preparation method of the medium comprises the following steps: 1, carrying out extrusion expanding treatment on rice husk; 2, fully mixing the expanded rice husk obtained in step 1 with a fertilizer and a bactericide, and standing; 3, respectively carrying out aerobic fermentation on mushroom dreg and straw; 4, adding sulfuric acid to a product obtained in step 3 to adjust the pH value; 5, mixing a product obtained in step 2 with a product obtained in step 4, adding vermiculite to the obtained mixture, using a sulfuric acid solution to adjust the pH value, and stirring to fully mix the material; and 6, sieving a product obtained in step 5, packaging, and discharging the packaged medium from a factory. All components in the multi-potential medium cooperate with nutrients, growth environment and disease prevention factors to organically form a homogenous, multi-potential, safe, efficient and simply operated seedling growing carrier, so various problems appearing in routine seedling growing using soil dressing + a seedling strengthening agent are thoroughly solved, and the rice output is improved.

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...
