Abstract

The invention discloses a rice seedling raising medium. The rice seedling raising medium is prepared from base plate soil and seed soil covering the base plate soil, wherein the base plate soil is prepared from raw materials in parts by weight as follows: 80-95 parts of a composted organic fertilizer, 10-20 parts of distillers'grains, 15-25 parts of needle mushroom residues, 1-5 parts of diammonium phosphate, 1-3 parts of potassium sulphate, 1-5 parts of zinc sulfate, 1-3 parts of monopotassium phosphate, 8-12 parts of calcium superphosphate, 2-4 parts of a water retaining agent, 1-2 parts of vermiculite, 5-10 parts of iron sulfate heptahydrate and 0.5-2.5 parts of a seedling strengthening agent. The rice seedling raising medium prepared from the composted organic fertilizer, the distiller's grains, the needle mushroom residues, vermiculite and micro nutritional agents has rich nutrients, stable properties and high content of organic matters and can supply sufficient nutrition to rice in the whole seedling raising period. The rate of rice emergency is high, the leaf emergence speed is high, root systems are rich, the root twisting property is good, the seedling rate is high, the cost is low, the seedling raising efficiency is high, and the mechanical transplanting quality is high.

Description

technical field [0001] The invention relates to the technical field of rice seedling raising, in particular to a rice seedling raising substrate. Background technique [0002] Substrate cultivation refers to a plant cultivation method in which the root system of a plant is fixed through a substrate and absorbs nutrient solution and oxygen in a certain place or container. According to statistics, 90% of the soilless cultivation forms in the world are substrate cultivation. The soilless cultivation substrate is a growth medium that can provide plants with a stable and coordinated water, air, and fertilizer structure. In addition to supporting and fixing the plants, it is more important to act as a nutrient and water carrier, so that the nutrients and water from the nutrient solution can be obtained. Transit, the plant root system selects and absorbs from it as needed. The seedling-raising substrate is a substrate specially used for seedling cultivation in the substrate. Wit...
