Rice seedling raising culture soil composted by water hyacinth

Abstract

The invention discloses rice seedling raising culture soil composted by water hyacinth. The culture soil has the advantages that a conical fermenting type is adopted, the water hyacinth is used as the main raw material and is mixed with livestock manure, a biological fermenting agent, egg shells, montmorillonite and the like to be composted and decomposed into a nutritional matrix, the quality and decomposing degree of the nutritional matrix are high, and the required nutritional elements of nitrogen, phosphor, potassium and the like required by the rice seedling are contained; the nutritional matrix and the agricultural fine soil are mixed to prepare the culture soil for seedling raising according to a mass ratio of 4:1, so that the cultured rice seeding has developed, thick and coiled roots, the carpet forming effect is good, the weight of the seedling carpet is light, and the requirement of machine seedling inserting is met; before the culture soil is loaded into a pot, a layer of coal residues is firstly paved at the pot bottom, then the culture soil is charged, and the water is sprayed according to the principle of small amount and multiple times, so that the culture soil is settled and dense, the heavy metal enriched in the water hyacinth can be dissolved, permeate down into the coal residue layer, and be absorbed by the coal residues, and then the pollution to the environment by the heavy metal is further prevented.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a culture soil for raising rice seedlings made of water hyacinth. Background technique [0002] In order to pursue the high yield of rice, people did not adopt scientific and reasonable methods when planting rice, resulting in more hormones after the rice matures. After the rice produced is eaten by people, human hormones are unbalanced, causing many children and even adults to develop Symptoms such as bad, obesity, and three highs affect human health. After years of research, it has been found that the key to rice planting lies in the cultivation of rice in the seedling raising stage, whether the rice can absorb beneficial nutrients in the seedling raising stage, and what nutrients it absorbs, which is related to the efficacy of the rice in the later period after it finally matures. The preparation of stage culture soil is particularly important. [0003] In view of the ...

AI Technical Summary

Problems solved by technology

[0003] In view of the large amount of bed soil, difficulty in taking soil, and poor quality in the existing rice seedling cultivation, many experts have devoted themselves to researching the replacement of traditional fine soil with nutrient substrates, or adding a certain proportion of nutrient soil ( or organic fertilizer, other substances) to solve the problems existing in rice seedling cultivation, and at the same time achieve the purpose of seedling cultivation with strong seedlings and vigorous roots

[0004] The reproductive ability of water hyacinth is extremely strong, and it can often dye the water surface green. When it reproduces in large numbers, it can cover the entire water surface, affect the gas exchange between the atmosphere and the water, reduce the penetration of light into the water body, affect the growth of underwater organisms, and increase the CO in the water body. 2 concentration, not only causing ecological hazards but also reducing the yield and quality of aquatic products; in some places, the density of water hyacinths even reached the point where people can walk on them, causing the shipping to be paralyzed for a while; in addition, water hyacinths also endanger the safety of water plants Production, water pump suction water hyacinth will cause filter blockage, waterworks stop production, causing harm to urban and rural drinking water supply

[0005] The current treatment method is to salvage the water hyacinth from the water and crush it, but it is difficult to reuse the crushed water hyacinth and cause new environmental pollution in the water hyacinth production area. Therefore, the present invention proposes a new method for processing water hyacinth : The culture soil prepared by composting water hyacinth as rice seedling bed soil
