Composite rice seedling cultivation matrix and preparation method thereof

Abstract

The invention discloses a composite rice seedling cultivation matrix and a preparation method of the matrix. The composite rice seedling cultivation matrix comprises the following components by weight: 60% of earthworm cast, 30% of vermiculite and 10% of nutrient soil by volume percent, wherein per cubic meter of matrix contains 7.5kg of ferrous sulfate heptahydrate. According to the invention, preparation method is simple, resource is rich and cost of materials is low, wastes are changed into valuable, the environmental pollution is reduced, and the seedling cultivation matrix is enough in nutrient and stable in properties. After the matrix is used for seedling cultivation, the operation is simple and convenient, and the labor intensity is lightened; furthermore, the rice seedlings are good in quality and high in percentage establishment of seedling. The matrix disclosed by the invention promotes the industrial development of rice transplanting of a rice transplanter, and is more beneficial to building ecological villages and towns and new villages.

Description

technical field [0001] The invention relates to an organic composition of a rice seedling raising substrate and a preparation method thereof, and belongs to the technical field of biological digestion and resource utilization of solid organic waste. 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. [0...
