Problems solved by technology

The disadvantages of this kind of seedling tray are 1. It is impermeable and airtight, which is not conducive to the material exchange between plants and soil 2. It is difficult to fertilize plant seedlings
The crops can only absorb the nutrients in the tray, which is not conducive to the water and fertilizer absorption of the crops, which limits the growth of the plants, resulting in poor seedling growth. 3. The seedling tray itself is made of plastic, which is difficult to degrade naturally and is easy to cause environmental pollution.
4. After the seedlings are raised, the plants need to be transplanted from the seedling trays. This process is complex and prone to seedling damage or even plant death, which reduces the survival rate

Embodiment 1

[0042] Embodiment 1: as Figure 1-2 As shown, the mineral-containing seedling tray includes the seedling tray body, grooves, through holes and diaphragms; there are multiple grooves evenly distributed on the tray body for seedling cultivation. There is a through hole at the bottom; the seedling tray containing minerals is made of polyethylene, the specification is 60cm×33cm, 300 holes / pan, and it is an inverted cone-shaped hole with a diameter of about 4.5cm and a height of 5cm.

[0043] The preparation method of the above-mentioned mineral-containing seedling tray comprises the following steps:

[0044] (1) Grinding raw materials: crush and grind the phosphate rock powder into a powder with a particle size of 200 mesh with mechanical equipment; dry to a water content of 4%; crush and grind the straw fiber powder with a mechanical The amount of water is 6%;

[0045] (2) Premixing: Weigh 100 parts of phosphate rock powder and 120 parts of straw fiber powder obtained in step (...

Embodiment 2

[0050] Embodiment 2: use this mineral-containing seedling raising tray (add 100 parts of phosphate rock powder, 120 parts of stalk fiber) seedling raising method for direct seeding, comprising the following steps:

[0051] (1) Preparation before sowing:

[0052] 1) Select the culture medium: choose one or more mixtures of container culture medium or decomposed cow dung or sheep manure, and mix it with loose soil. At the same time, adjust the pH of the culture medium to maintain its pH at 6.2;

[0053] 2) Mix the culture medium in step 1), put it into the groove of the seedling tray containing minerals, and smooth it gently;

[0054] 3) Irrigate the bottom water thoroughly with a fine nozzle. The size of the water droplets should not impact the soil surface and keep the soil surface flat. Irrigate again with fungicide after watering;

[0055] 4) Seed treatment: Soak pansy seeds in water at a constant temperature of 25°C for 20 hours, then sterilize them, rinse them with clean...

Embodiment 3

[0060] Embodiment 3: use this mineral-containing seedling raising tray seed (add 120 parts of phosphate rock powder, 180 parts of stalk fiber powder) direct seeding method, comprising the following steps:

[0061] (1) Preparation before sowing:

[0062] 1) Select the culture medium: choose one or more mixtures of container culture medium or decomposed cow dung or sheep manure, and mix it with loose soil. At the same time, adjust the pH of the culture medium to maintain its pH at 6.2;

[0063] 2) Mix the culture medium in step 1), put it into the groove of the seedling tray containing minerals, and smooth it gently;

[0064] 3) Irrigate the bottom water thoroughly with a fine nozzle. The size of the water droplets should not impact the soil surface and keep the soil surface flat. After watering, use fungicides to irrigate again;

[0065] 4) Seed treatment: Soak pansy seeds in water at a constant temperature of 25°C for 20 hours, then sterilize them, rinse them with clean water...

Abstract

The invention relates to a mineral containing nursery seedling plate and a preparation method thereof. The mineral containing nursery seedling plate is prepared from the following components in parts by weight: 80 to 120 parts of powdered rock phosphate, 40 to 200 parts of fiber powder, 20 to 90 parts of degradable powder, and 1 to 25 parts of additives. The experiment shows that the powdered rock phosphate and straw fiber powder are added to the degradable plastic, the powdered rock phosphate added can be slowly released by a long-lasting manner during the plant growing, so that the oxygen supply is improved and the fertilizer effect of the nursery seedling plate is improved; meanwhile, the plastic degrading is improved; the mineral containing nursery seedling plate has a transverse partition and is easily broken to be directly buried into the soil for degrading or recycling, thus the transplanting process is saved, the survive rate of seedlings can be increased, and meanwhile, the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a seedling tray for cultivating plants, in particular to a mineral-containing seedling tray and a preparation method thereof. Background technique [0002] At present, the mineral-containing seedling trays on the market use plastic as the main raw material for production, such as seedling trays produced with PS (polystyrene) materials or PVC (polyvinyl chloride) materials. The disadvantage of this kind of seedling tray is that 1. it is impermeable and airtight, which is not conducive to the material exchange between plants and soil; 2. it is difficult to fertilize plant seedlings. The crops can only absorb the nutrients in the tray, which is not conducive to the absorption of water and fertilizer by the crops, thereby limiting the growth of the plants, resulting in poor seedling growth. 3. The seedling tray itself is made of plastic, which is difficult to degrade naturally and is easy to cause environmental pollution. 4. The p...
