The way to cultivate rice seedlings by automatic tray seeding machine

Table of Contents

Rice seedling cultivation in greenhouse is an advanced and practical technology to achieve early seedling growth, and early seedling transplantation, defeating low temperature damage, and obtaining high yield. Rice seedlings cultivated by automatic tray seeding machine in the greenhouse has low investment costs, simple operation and convenient management. It is the current ideal way to raise seedlings, and is also a key link in the rice high-yield cultivation system.

Rice variety selection

Select local varieties that are stable, good quality, high-yield and disease-resistant. Most important, the seed purity is not less than 98%; the germination rate is not less than 95%; the moisture content is not higher than 14.5%. Meanwhile, the seeds must be replaced once a year.

Seed dosage

40-60 kg of seeds per hectare.

Seed treatment

Dry the seeds for 2 to 3 days in the sunny day, and flip them 3-4 times a day to increase the germination rate of them.

What should you prepare?

Hotbed configuration

The soil on the hotbed is granular, no grass seeds, no bacteria and has good permeability. What’s more, it contains more organic matter, and the pH is 4.5-5.5.

Choice of greenhouse

You should choose a steel greenhouse for rice or a bamboo one made by yourself. The size of the greenhouse is based on the area of the field.

Selection of seedbeds

Choose a land with no pollution, flat terrain and sufficient light. In addition, the land must be fertile, and can reach water for convenient irrigation.

Seedling trays preparation and selection

22-25 seedlings trays are generally required for per acre of field. The isolation layer can be film with hole and non-woven fabric etc.

Sowing method

1. The thickness of the subsoil is 2 cm, and the thickness should be uniform with flat soil surface.

2.The amount of sowing. Each tray weights 120-150g, and there is no seed leakage and overlap.

4. Watering and soil disinfection. The moisture must ensure that the soil is saturated and the amount of disinfectant should not be too large, otherwise it will affect the growth of rice seedlings.

5. The soil cover should be uniform and the thickness should be 0.3-0.5 cm.

6. Weeding and covering film. After covering the soil, the bed surface should be covered with plastic film or thin non-woven fabric to achieve the moisture retention and heat preservation.
