What are the technical points of rice seedling raising?

1, rice seed treatment: We need to treat the seeds before seedling raising, which can improve the germination rate of the seeds. If we want to improve the germination rate of seeds, the first thing to do is to dry the seeds and then soak them with some drugs. Generally, seeds are soaked with 100 grams or prochloraz and cartap for about 5-6 minutes.

2. Water management: Water management during rice seedling raising is also very important. The water in the nursery area does not need to be watered too much, and generally it is enough to soak the surface of the border. Secondly, when the moisture in the field decreases, water it in time to keep the soil humidity at the original humidity.

3. Soaking seeds to accelerate germination: put all the previously treated seeds into a net bag. When accelerating germination, the temperature must also be controlled. Only the right temperature can ensure the smooth germination of seeds. It is best to control the temperature at about 30 to 32 degrees when accelerating germination. When the bud roots grow to about 2 mm, take them out and put them in the shade. It is also possible to sow at this time. The next step is to raise seedlings. After germination, the seedlings will grow up gradually. When they grow to the length of chopsticks, they can be pulled out and replanted, otherwise rice will not be produced.

4. Transplanting: all the seedlings should be pulled out, then tied into a small bunch of seedlings, all of which should be transferred to a large paddy field, and then these seedlings should be inserted, but the spacing should be kept a little larger. If it is too close, it will affect the normal growth and yield of rice.
