Problems solved by technology

[0004] With the development of the times, people also use different materials to make a lot of artificial seedling substrates to cultivate seedlings, but there are still many deficiencies in practice, such as the low rate of seedlings, and the seedlings are prone to produce aerial and aquatic roots. In Honda, the seedlings are slow, and the greening period is delayed, which affects the yield, quality and maturity period; although there are substrates to replace the seedling soil on the market, the product cannot guarantee the integrity of the root system during mechanical transplanting and replace the original plastic seedling tray. cumbersome, expensive, etc.

preparation example Construction

[0045] The present invention provides the preparation method of described seedling raising matrix plate, comprises the following steps:

[0046] 1) Prepare puffed rice husk, broken pieces of corn stalks, decomposed manure, grass carbon soil and vermiculite with water to make a slurry, adjust the acidity to 4.5-5.0, and prepare a disk-making slurry;

[0047] 2) The disc-making slurry is sucked into a mould, dried and solidified at 250-270° C. to obtain the initial shape of the seedling-raising matrix disc;

[0048] 3) Holes are punched on the degradable paper according to the distribution positions of the cavities in the seedling-raising matrix tray, and the degradable paper punched with holes is wrapped and glued on the bottom surface and side wall of the seedling-raising matrix tray prototype to obtain a seedling-raising matrix tray.

[0049] In the invention, the expanded rice husk, broken pieces of corn stalks, decomposed excrement, grass carbon soil and vermiculite are pre...

Embodiment 1

[0062] Component Preparation Method:

[0063] 1. Preparation of puffed rice husk: Pass the rice husk through a sieve of 6-8mm, clean and remove impurities, puff it with an extruder at a temperature of 350° C., collect the puffed product to obtain puffed rice husk.

[0064] 2. Preparation of broken pieces of corn stalks: drying the corn stalks, pulverizing them, sieving, and collecting broken pieces of corn stalks with a fineness below 10 mm.

[0065] 3. Preparation of decomposed cow dung: adjust the water content of the cow dung to 45%, pile the cow dung into a trapezoidal body, turn the pile when the central temperature of the cow dung is higher than 55°C, and turn the pile once every 3 days for a total of 4 times. Ferment the turned cow dung under closed conditions for 20 days to obtain decomposed cow dung.

[0066] 4. Preparation of fine grass carbon soil: pulverize the purchased grass carbon soil, sieve, and collect the undersieve to obtain fine grass carbon soil.

[00...

Embodiment 2

[0069] 1. Weigh according to the following weight: 35kg puffed rice husk, 35kg crushed corn stalks, 15kg fine grass carbon soil, 15kg decomposed cow dung and 20kg vermiculite.

[0070] 2. Preparation method of automatic covering matrix disc

[0071] Mix puffed rice husk particles, crushed corn stalks, decomposed cow dung, vermiculite, and peat materials according to the above ratio. Mix every 1 kg of dry material with 40 kg of water, while mixing, spray an appropriate amount of diluted acid solution to adjust the pH value to 5.0. Then pump the prepared mixed slurry into the slurry tank of the plate making machine, use the mold to absorb and form, and dry with 260°C high-temperature hot air to obtain the prototype. The initial type is prepared according to the specification of rice seedling tray 280 × 580mm in the universal type dry nursery machine, and is prepared into specifications of width 280 × length 580mm, thickness 20mm (the thickness of the bottom of the cavity is 10m...

Abstract

The invention provides an automatic seed covering seedling raising substrate plate for rice and a preparation method and application thereof, and belongs to the technical field of rice seedling raising. The automatic seed covering seedling raising substrate plate for the rice is based on the structure of a honeycomb, expanded rice husks, corn stalk, vermiculite, decomposed manure and turfy soil serve as the components, mold shaping and high temperature drying are conducted, and an initial type is obtained; each hole serves as an independent unit, and water expansion materials are used as barriers between the holes, the bottom and the periphery of a whole seedling tray are pasted and fixed with degradable paper, and according to the specification of the seedling tray applied by a rice transplanter, a rice dry raising machine is obtained for inserting an automatic seed covering seedling raising substrate plate. The automatic seed covering seedling raising substrate plate is applied for raising seedlings, not only is the seedling raising soil is replaced, but also a plastic seedling raising tray is replaced, the automatic seed covering seedling raising substrate plate can be directlyplaced for use, the process that covering is conducted again after sowing is omitted, the efficiency of rice seedling raising is improved, a substrate body suitable for cold region seedling root system growth is created, the stress resistance in the seedling growing process is enhanced, and strong seedlings are cultivated.

Description

technical field [0001] The invention belongs to the technical field of rice seedling raising, and in particular relates to a rice automatic covering seed seedling raising matrix tray, a preparation method and application thereof. Background technique [0002] Rice is one of the main crops in my country's agricultural production. Since its development, planting technology, unit output, economic benefits and many other aspects have been significantly improved, which has played an important role in ensuring my country's food security. With the development of the times, the requirements for the yield and quality of rice production are getting higher and higher. In particular, the seedling raising technology in the dry-breeding and sparse planting of rice is particularly important. As the saying goes, "the seedlings are good for half a year's grain." Cultivating high-quality seedlings is crucial to improving rice yield and quality. [0003] At present, in order to raise good se...
