The Latest Rice Seed Germination Techniques: This Tutorial Is All You Need

Before sowing, rice must go through a germination process; unlike other crops, it cannot be sown directly. After germination, the seed germination rate can reach 95%, and the sprouts are strong with short roots, growing more vigorously. So what exactly is the germination method? Come take a look at the detailed introduction from QinNong Net.

1. Sun-drying the seeds

The very first step of germination is sun-drying the seeds. Choose a sunny day and expose the rice seeds to the sun for one or two days, but be careful not to place the seeds directly on concrete ground, as this will scorch them to death. It is best to prepare a tarpaulin and spread the seeds evenly on it, turning them occasionally while drying to ensure even exposure. Sun-drying can increase the seeds' water and light permeability, and also has a sterilizing effect. After sun-drying is complete, place the seeds in a dry, cool place to cool down for later use.

2. Seed selection

After sun-drying comes seed selection. Seed selection mainly involves choosing high-quality seeds and removing inferior ones, so that after sowing the seedlings grow robustly and uniformly. Clean water can be used for seed selection: first soak the seeds in water, and after absorbing water the seeds will sink, while empty husks will float. This way you can select plump, high-quality seeds and improve the germination rate.

3. Soaking the seeds

There are many methods for soaking seeds, with common ones including soaking by day and airing by night, intermittent soaking, and chemical soaking. When soaking, place the seeds in warm water; generally the soaking time is 24-48 hours, and if soaking exceeds 48 hours it is unfavorable for germination. The specific time depends on the variety and water temperature, generally judged by the seeds showing white tips. Note that the chemical soaking method is better than ordinary methods, but you must pay attention to the concentration of the solution and the water temperature, and also frequently change the water or soak in running water. After soaking is complete, germination can begin.

4. Germination

During germination, do not put the seeds in woven bags or leave them exposed to the sun. You can choose double-layer burlap sacks, preferably ones that have been disinfected and sterilized to ensure safety during germination, and soak the burlap wet. Then spread a layer of clean straw on the ground in a greenhouse environment, lay out the soaked burlap, scatter the seeds evenly on top, and cover with another burlap sack. Alternatively, you can put the seeds directly into a well-ventilated burlap sack. Keep the temperature between 35-38; when it is too hot, turn them to dissipate heat, and when the temperature is too low, find ways to raise it. After one to two days, once the seeds show white tips and break through the hull, germination is successful and they are ready for sowing.
