Problems solved by technology

In recent years, a number of power plants using straw as energy have been built in various places, and a large amount of plant ash has been produced in a concentrated manner. Due to the low bulk density of plant ash, high packaging and transportation costs, and inconvenient field application, it is hoped that all plant ash produced by straw power plants can be used directly. It is difficult to use as fertilizer
If the plant ash is directly discharged as garbage, it will not only waste resources, but also pollute the environment
Extract potassium from plant ash and use it as fertilizer. Although it can reduce the loss of potassium resources, the ash after depotassium removal still needs to be processed

Embodiment 1

[0022] Prepare the plant ash seedling substrate for seedling cultivation in the plug tray: the depth of the pool is more than 0.6m, and the volume is 3m 3 Add plant ash weighing about 1T in the washing filter tank, rinse with water until the conductivity of the water outlet is less than 2ms / cm, stop washing and filtering, discharge the ash, centrifugal dehydration, take the dehydrated ash 1000kg, the water content is about 40% (wet basis ), the conductivity of its salt content is 1.5ms / cm. Add 10% sulfuric acid (H 2 SO 4 ) and 10% ferrous sulfate (FeSO 4 .7H 2 (2) 150kg of mixed acid-adjusting solution, fully mix well, pile up and place for 4 hours; then add 3% nitric acid solution 100kg, cross 100 mesh sieve attapulgite 150kg, 1.5% polyacrylamide (PAM) solution 100Kg, add while adding Stir, mix well and serve. The formulated matrix has a bulk density of 0.3g / cm 3 About, the total porosity is about 90%, of which the ventilation pores account for about 20% of the total po...

Embodiment 2

[0024] Prepare plant ash seedling raising matrix nutrient block: get the ash residue 1000kg that washes salt and dehydration, add concentration to be 20% sulfuric acid (H 2 SO 4 ) and 20% ferrous sulfate (FeSO 4 .7H 2 80kg of mixed acid-adjusting liquid of (0), fully mix thoroughly, pile up and place 5 hours; Add 20kg of 10% ammonium nitrate solution, 150kg of attapulgite, 5% PVA solution 50Kg of 100 mesh sieves, stir while adding, fully mix well . Press the block with a mold, the finished product has a diameter of 3.5cm, a height of 4cm, and a semicircular seeding hole with a depth of 0.5cm in the center of the upper end. The bulk density of nutrition block is about 0.45g / cm 3 , The total porosity is about 80%. When water is supplied from the bottom of the nutrition block, the time for the whole block to absorb enough water is ≤30min. The nutrient block can be directly used for raising seedlings, and can also be used after being dried. The nutrient block is resistant to...

Embodiment 3

[0027] The making of the plant ash seedling-raising matrix that is used for rice machine-transplanted seedlings: get 1000kg of ash slag after washing salt and dehydration, add ferrous sulfate (FeSO 4 .7H 2 (2) 75kg, ammonium sulfate 4kg, ammonium dihydrogen phosphate 0.5kg, fully mix well, pile up and place more than 3 days (because what added is crystal ferrous sulfate (FeSO 4 .7H 2 (2), it needs to be piled up for a long time to allow it to fully react); add yellow clay 300kg, 0.2% PAM solution 300Kg of 40 mesh sieves, stir while adding, fully mix well, can be used for rice machine transplanting and seedling raising. The formulated matrix has a bulk density of 0.3g / cm 3 The total porosity is about 85%, of which the ventilation pores account for about 15% of the total pores, pH7.5, the available nitrogen content reaches 260mg / L, and the available phosphorus content reaches 70mg / L. 1.5kg of the finished product is installed in each standard tray as subsoil, and the upper pa...

Abstract

The invention discloses a plant ash seedling-growing matrix and a preparation method thereof. The matrix is prepared by mixing the following raw materials: 100 parts of plant ash desalted through washing and dewatered through centrifugation, 10-35 parts of soil and 0.02-0.35 part of binder. The preparation method comprises the following steps of: adding a nitrogen element to increase the content of rapid available nitrogen to reach 100-300 mg / L, or adding the nitrogen element to increase the content of rapid available nitrogen to reach 100-300 mg / L and simultaneously adding a phosphorus element, adjusting the pH of a material to be 6-8 by using an acid, and adjusting the moisture content of the material to be 40-55%. The matrix is applicable to vegetables, flowers, tobaccos, nursery-grown plants and field crops, such as rice, corns, cotton and other various crops requiring seedling growing and transplanting. When the matrix is used for growing seedlings, the seedlings are strong and have no disease, good root system development, short seedling recovery period after transplanting and high survival rate.

Description

Technical field: [0001] The invention relates to the technical field of agricultural cultivation, in particular to a soilless seedling-raising substrate, and more particularly to a plant ash seedling-raising substrate and a preparation method thereof. technical background: [0002] The use of soilless seedling substrates to cultivate crop seedlings has been widely used in vegetables, flowers, tobacco, seedlings and even field crops such as rice, corn, cotton and other crops that require seedling cultivation and transplanting. The composition of the seedling substrate is mostly organic materials, such as peat, decomposed straw, manure, mushroom residue, etc., supplemented by some inorganic materials, such as vermiculite, perlite, rock wool, slag, gravel, etc. Though also someone adds plant ash in the preparation nursery matrix, but all as auxiliary material, consumption is less, as the patent publication number is CN1820579, and name is called a kind of soilless culture compl...
