Embodiment 1

[0027] A kind of paddy rice seedling raising matrix, it is made of the raw material of following weight portion:

[0028] 45 parts by weight of 4-year-old pine needle layer, 38 parts by weight of orchard soil, 12 parts by weight of peat soil, 8 parts by weight of river sand, 50 parts by weight of fermented manure, and 15 parts by weight of stewed corncob material; prepared by using manure and corncob as main raw materials The rice seedling substrate not only reduces the cost of manure and corn cobs, avoids environmental pollution, but also realizes the full utilization and multiplication of resources. The rice seedling substrate has a reasonable ratio and rich nutrition, which is suitable for the growth of rice seedlings. The content of heavy metals is low, and it can greatly promote the absorption of silicon by rice seedlings, thereby inhibiting the accumulation of cadmium in seedlings, reducing cadmium pollution, promoting photosynthesis, making rice seedlings grow vigorously...

Embodiment 2

[0035] A rice seedling raising substrate and a preparation method thereof, comprising the following steps:

[0036] Decomposed manure: spread the sheep manure and cow manure to a thickness of 5cm and evenly dry them, turn them up and down every 2 days, and dry them for 10 days. Configure the ethanol solution containing 1.25% glutaric acid, dilute the above ethanol mixed solution to 100 times of ethanol mixed diluted solution, layer every 1000Kg manure, evenly add 600g ethanol mixed diluted solution, 3Kg microbial decomposing bacteria agent, microbial decomposing bacteria agent It is a mixed strain of lactic acid bacteria, Bacillus subtilis, Bacillus licheniformis, nitrogen solubilizing bacteria, phosphate solubilizing bacteria and actinomycetes with a weight ratio of 2:6:4:2:2:1, stir well and add sterile water The water content is 60%, and then piled into a pile body with a bottom width of 3m, a top width of 2m, and a height of 1.5m. The surface of the pile is covered with 0...

Embodiment 3

[0041] A rice seedling raising substrate and a preparation method thereof, comprising the following steps:

[0042] Decomposed manure: Spread the chicken manure and human manure to a thickness of 4m and evenly dry them, turn them up and down every 2 days, and dry them for 6 days. At the same time, remove stones, plastics, metal blocks and other impurities, and roll them to make the particle size less than 1cm; Configuration contains the ethanol solution of 0.84‰ methyltriethoxysilane and 1.22% glutaric acid, the ethanol mixed solution is diluted to 60 times of ethanol mixed diluted solution, every 1000Kg manure is layered, evenly added 400g ethanol mixed diluted solution, 2Kg microbial decomposing bacteria agent, microbial decomposing bacteria agent is a mixture of lactic acid bacteria, Bacillus subtilis, Bacillus licheniformis, nitrogen-decomposing bacteria, phosphorus-solubilizing bacteria and actinomycetes with a weight ratio of 3:5:3:1:1:1 After fully stirring, add sterile...

Abstract

The invention provides a rice seedling breeding culture medium, and belongs to the field of rice seedling breeding. The culture medium is prepared from, by weight, 45-48 parts of pine needles with theage of 4-5 years, 38-40 parts of orchard soil, 12-15 parts of peaty soil, 8-10 parts of river sands, 50-65 parts of fermented manures and 15-18 parts of braised maize cob materials. The invention further discloses a preparation method of the rice seedling breeding culture medium. The rice seedling breeding culture medium has the advantages that the proportioning is reasonable, the nutrients are abundant, the process is simple, the price of the culture medium is low, the culture medium is environmental friendly, the treatment cost of agricultural waste is reduced, environmental pollution is prevented, the content of cadmium in the culture medium can be effective reduced, the formation of xylem of young seedlings and plants can be accelerated, the absorption of silicic acid is enhanced, theabsorbing and transferring of cadmium in soil are inhibited, and the enrichment of the cadmium in the young seedling bodies of the rice is reduced.

Description

technical field [0001] The invention belongs to the field of rice seedling raising, and in particular relates to a rice seedling raising substrate and a preparation method thereof. Background technique [0002] The discharge of industrial "three wastes" and the unreasonable use of cadmium-containing pesticides and fertilizers have led to aggravated cadmium pollution in farmland soil, which in turn affects the quality and safety of agricultural products and poses an increasing potential threat to human health. According to the "National Soil Pollution Survey Bulletin" released in 2014, cadmium ranks first in the heavy metal pollution of cultivated land. Cadmium is a non-essential nutrient element, and it is highly toxic even in trace amounts, which can cause kidney damage in humans, and affect the cardiovascular system, musculoskeletal system and female reproductive system. Therefore, it is of great significance to control the cadmium pollution in farmland soil and ensure th...
