Embodiment 1
[0035] A method for raising seedlings of organic rice transplanted by machine, specifically comprising the following treatments:
[0036] (1) Straw tendon treatment: Soak the straw tendon with 30 times of vinegar solution, wash it with water after 24 hours;
[0037] (2) Select the seedling-raising substrate: mix the decomposed vinegar grains and garden soil with a volume ratio of 4:1 as the seedling-raising substrate;
[0038] (3) Sowing: Artificial sowing is adopted, and the seeds need to be soaked first and then germinated. The method for soaking the seeds is that the dried rice seeds are soaked in 30% edible vinegar for 24 hours, and then rinsed with clear water. Germination adopts conventional methods to dew white. Lay the treated grass tendons on the seedling tray with a thickness of 0.5cm, cover the seedling raising substrate on the grass tendons, 0.5cm away from the upper edge, artificially sow the seeds evenly into the seedling tray, cover with a 0.3cm thick Seedlin...
Embodiment 2
[0044] A method for raising seedlings of organic rice transplanted by machine, specifically comprising the following treatments:
[0045] (1) Straw tendon treatment: Soak the straw tendon with 30 times of vinegar solution, wash it with water after 24 hours;
[0046] (2) Select the seedling-raising substrate: mix the decomposed vinegar grains and garden soil with a volume ratio of 4:1 as the seedling-raising substrate;
[0047] (3) Sowing: use a seeder to sow, spread the treated grass tendon in the seedling tray with a thickness of 0.5cm, cover the seedling raising substrate on the grass tendon, and spread the seeds evenly with a seeder Sow into the seedling-raising tray, covered with a 0.2cm-thick seedling-raising substrate;
[0048] (4) Lay the installed seedling raising tray on the ridge of the seedling field, cover it with 0.3cm thick decomposed vinegar grains, fill the seedling field ditch with water, and the height of the water is equal to the bottom edge of the seedling...

Abstract
The invention discloses a seedling culture method capable of realizing mechanical seedling transplanting of organic rice. The method comprises the following steps that firstly, straw stems are processed, a proper seedling culture substrate is selected, the processed straw steams are flatly paved in seedling culture discs, the thickness is 0.3 to 0.5cm, the seedling culture substrate covers the straw steams, the distance from an upper edge opening is 0.5cm, seeds are planted into the seedling culture discs by labors or by a seeding machine, and the seedling culture substrate with the thickness being 0.2 to 0.3cm covers the seeds; the charged seedling culture discs are flatly paved onto a ridge of the seedling field, rotten vinegar residue with the thickness being 0.2 to 0.3cm covers the seedling culture discs, and non-woven fabrics cover the ranged seedling culture discs; the water level is maintained in the seedling culture period, and after 18 days, the seedling culture discs can be used for mechanical seedling transplanting. The seedlings cultured by straws and the vinegar residue have the advantages that the leaves are strong, the color is green, and seedlings are uniform and regular. The seedling root system formation is obviously promoted, the root winding is promoted, the root winding force is improved, the root systems are wound into a whole and cannot be scattered after being lifted, the problem of seedling missing due to easy disc scattering of mechanical seedling culture of the existing production method adopting plastic disc seedling culture can be effectively solved, the mechanical seedling transplanting operation efficiency is greatly improved, and the seedling loss is reduced.
Description
technical field [0001] The invention belongs to the technical field of agriculture, and relates to a seedling raising method, in particular to a seedling raising method of organic rice machine transplanting. Background technique [0002] Seedling raising is one of the important links in the early stage of rice production, because the quality of seedlings is directly related to the growth and appearance of rice in the early stage and the yield frame in the later stage. Therefore, rice production has always attached great importance to the cultivation of seedling quality. [0003] According to the changes of the times and the progress of technology, rice seedling raising includes water seedling raising, wet seedling raising, dry seedling raising, floppy seedling raising and industrial seedling raising. [0004] Plastic tray seedling raising is based on dry seedling raising. It is a special seedling raising technology developed in combination with rice seedling throwing technol...
