rice cultivation technology

Select some highly resistant and high-yielding seeds, soak them in water with carbendazim for a day, then remove and rinse them and put them in a bucket to germinate. After the seeds germinate, spread them evenly on the soil, then cover them with a thin layer of soil and cover them with a thin film to allow them to emerge. When the seedlings grow to one and a half months, they will be transplanted to the field according to the distance between the rows of plants and 14*30cm. Finally, the basic management work such as water and fertilizer, pest control and so on will be done well to achieve high yield.

How to sow rice?

1. Seed drying

The first step to promote germination is to dry the seeds, choose a sunny day to expose the rice seeds for a day or two, but be careful not to put the seeds directly on the cement ground, which will directly kill the seeds. It is best to prepare a piece of cloth. spread the seeds evenly on it and make sure it is turned over when drying the seeds. Drying seeds can increase the water and light permeability of seeds, as well as bactericidal effect. After drying the seeds, put the seeds in a dry, cool place to cool.

2. Seed selection

Seed selection begins after drying. Seed selection is mainly to select high-quality seeds and get rid of inferior seeds, so that the seedlings can grow healthily and neatly after sowing. Seeds can be selected with clean water, soaking the seeds in water first, the seeds will sink after absorbing water, while the empty shell species will float, so that high-quality seeds with full grains can be selected to improve the germination rate.

3. Soaking seeds

There are many kinds of seed soaking methods, such as day and night dew, intermittent seed soaking, drug soaking and so on. When soaking seeds in warm water, the seed soaking time is generally 24-48 hours, but if the seed soaking time is more than 48 hours, it is disadvantageous to germination. The specific time is determined by variety and water temperature, and generally seed whitening is taken as the standard. It should be noted that the method of soaking seeds with medicine is better than the general method, but we should pay attention to the concentration of medicine and water temperature, and we should change water frequently or soak in living water. Seed soaking can be carried out after germination.

4. Sprouting

When promoting germination, it is not appropriate to put the seeds in woven bags or put them in the sun. You can choose double-layer sacks. The sacks had better be disinfected and sterilized to ensure the safety of sprouting and soak the sacks. Then put a layer of clean straw on the ground in the greenhouse environment, spread the soaked sacks, spread the seeds evenly on it, and cover them with another sack. Or you can use a good breathable sack to directly put the seeds into it, keep the temperature between 35 and 38, turn in the middle to dissipate heat when the temperature is high, and find a way to increase the temperature at low temperature. After one to two days, after the seeds can be exposed white and broken chest, the germination will be successful and can be sown.

The above is the introduction of rice cultivation technology, I hope it will be helpful to you.
