Water-retention soilless culture medium

Abstract

The invention discloses a water-retention soilless culture medium, belonging to the field of agriculture cultivation technique. The water-retention soilless culture medium comprises the following components in percentage by weight: 20-30 percent of organic fertilizer, 10-15 percent of grass carbon, 16-20 percent of fine sand, 8-12 percent of rough sand, 8-12 percent of vermiculite, 5-8 percent of perlite, 5-7 percent of calcium potassium magnesium powder, 3-6 percent of weathered coal, 3-5 percent of ground phosphate rock, 1-2 percent of bentonite, and 0.4-0.8 percent of water-retention agent, wherein the organic fertilizer is prepared by mixing, fermenting and bubbling animal excrements, plant straws and the like, and has moisture rate of 8-15 percent after being aired and screened, the granularity of grass carbon, vermiculite and perlite is smaller than 60 meshes, and the granularity of other components is less than 80 meshes. The preparation method comprises the steps of weighing all components according to proportion, agitating and mixing, drying, inspecting, metering and packaging. The water-retention soilless culture medium has the advantages of being simple in production technique, reasonable in proportion and excellent in applicability, and can be widely applied for breeding and transplantation of tree seedlings and grasses, as well as vegetable, fruits, grains, flowers, trees and the like in drought, deserts and salinization regions.

Description

1. Technical field: [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a water-retaining soilless cultivation substrate and a production method thereof. 2. Background technology: [0002] The planting, cultivation, growth, development, flowering, and fruiting of traditional plants, especially crops, require sufficient water and fertile soil. Due to the continuous reduction of farmland resources, the conflicts between industry and agriculture, and between urban and rural areas increasingly prominent. Now, with the deepening of the four modernizations, especially the modernization of agriculture, the advancement of science and technology and the development of the economy, the cultivation and planting of plants is no longer completely dependent on land resources, and the technology of soilless cultivation has been developed by leaps and bounds. In modern agricultural production, the soilless cultivation technology not...

Problems solved by technology

[0005] In the development of soilless cultivation substrates, peat and perlite are mostly used as basic materials at present, and some materials such as vermiculite, stone sand, stone grains, foam plastics, and fermented and carbonized plant straws are simply mixed. One is that after the substrate absorbs water, the peat, vermiculite, and straw in it will be impregnated with water and become thinner and sink, while the perlite will float to the surface of the substrate, which reduces the permeability of the substrate and affects the normal operation of the root system. Growth and development, after the perlite floats to the surface, there will be algae attached to it, making the substrate rotten and smelly
