Problems solved by technology

The commonly used traditional seedling raising substrate uses non-renewable peat, and it also greatly increases the difficulty and cost of rice mechanized transplanting and seedling raising. At the same time, the nutrient solution in the substrate will also cause many environmental problems.

preparation example Construction

[0038] The present invention also provides a preparation method of the seedling-raising substrate described in the above-mentioned technical solution, comprising the following steps:

[0039] 1) After mixing furfural slag, straw charcoal, chicken manure and water, heap fermentation to obtain fermentation substrate;

[0040] 2) drying and pulverizing the fermented substrates obtained in the step 1) successively to obtain pulverized substrates;

[0041] 3) mixing the pulverized substrate obtained in the step 2) with wood vinegar, phosphate rock powder and potassium mineral powder to obtain a seedling-raising substrate for organic rice.

[0042]In the present invention, the mixture obtained by mixing furfural slag, straw charcoal, chicken manure and water is built up and fermented to obtain a fermentation substrate. In the present invention, the mixing method is not particularly limited, and a conventional mixing method may be used. Preferably, in the obtained mixture, water ac...

Embodiment 1

[0062] Furfural slag with a water content of 30wt%, straw charcoal, chicken manure with a water content of 60wt%, and water were mixed and piled up, covered with a plastic film, and fermented at a temperature of 10°C for 33 days. During the fermentation period, the pile was turned every 4 days to obtain a fermentation substrate. The volume ratio of the furfural residue, straw charcoal and chicken manure is 3:1:1, and the amount of water added is 50% of the total mass of the furfural residue, straw charcoal, chicken manure and water.

[0063] The obtained fermentation substrate was dried at 80°C to obtain a dry substrate with a water content of 35%. The obtained dry matrix was pulverized into a pulverized matrix with a particle size of 3 mm.

[0064] The obtained pulverized substrate is mixed with wood vinegar, phosphate rock powder with a particle diameter of 2 mm and potassium mineral powder with a particle diameter of 0.8 mm to obtain a seedling-raising substrate for organic...

Embodiment 2

[0068] Furfural slag with a water content of 40wt%, straw charcoal, chicken manure with a water content of 40wt%, and water were mixed to build a pile, covered with a plastic film, and fermented at a temperature of 25°C for 27 days. During the fermentation period, the pile was turned every 2 days to obtain a fermentation substrate. The volume ratio of the furfural residue, straw charcoal and chicken manure is 8:1:1, and the amount of water added is 70% of the total mass of furfural residue, straw charcoal, chicken manure and water.

[0069] The obtained fermentation substrate is dried in the shade at 10-25° C. in a cool and ventilated place to obtain a dry substrate with a water content of 30%. The obtained dried matrix was pulverized into a pulverized matrix with a particle size of 1 mm.

[0070] The obtained pulverized substrate is mixed with wood vinegar, phosphate rock powder with a particle diameter of 0.5 mm and potassium mineral powder with a particle diameter of 2 mm t...

Abstract

The invention provides a seedling raising substrate for organic rice prepared by using furfural residue. The seedling raising substrate is prepared from the following ingredients: a fermentation substrate, wood vinegar, phosphorite powder and potassium ore powder, wherein the fermentation substrate is a product which is obtained through mixing the furfural residue, straw charcoal, chicken manure and water and carrying out piling and fermenting; the volume ratio of the furfural residue to the straw charcoal to the chicken manure is (3 to 8): (1 to 2): 1; and the ratio of the volume of the fermentation substrate to the mass of the wood vinegar to the mass of the phosphorite powder to the mass of the potassium ore powder is 1m<3>: (5 to 20)Kg: (0.5 to 1.5)Kg: (1 to 2)Kg. Through carrying out rice seedling raising by using the seedling raising substrate prepared by the method, the prepared rice seedlings are great in plant height, high in dry weight, large in quantity of adventitious roots and high in plumpness and meanwhile are free of disease incidence.

Description

technical field [0001] The invention belongs to the technical field of seedling-raising substrates, and in particular relates to an organic rice seedling-raising substrate prepared by using furfural slag and a preparation method thereof. Background technique [0002] The seedling substrate is a material specially used for seedling cultivation, which provides nutrients for the seedlings throughout the growth period and is the key to cultivating strong seedlings. Commonly used seedling substrates in the prior art tend to be broad-spectrum, and there are relatively few researches and results development on designing special seedling substrates according to the physiological characteristics of different plants and the requirements for substrates. [0003] At present, people pay attention to the organic planting of rice from transplanting to harvesting, but ignore the organic planting in the seedling raising period, and there are very few organic rice in the formal sense. The de...
