1. Collect rice seeds at seedling stage and sow them in soil. When the growth conditions are suitable, the seeds will pull out the radicle, grow up and emerge from the soil. This is the stage when the seedlings begin to rise. Before leaves grow, they absorb nutrients from the soil by absorbing roots. After the leaves grow, they can not only be absorbed by the roots, but also be converted into nutrients by absorbing the light of the leaves.

The second is the tillering stage, when the seedlings grow for a period of time and then transplant. This stage from transplanting to jointing stage is called tillering stage. Because the root system will be damaged after transplanting, it will take some time to recover, and the aboveground part will take about 5-7 days to recover.

Thirdly, it usually takes one month from jointing stage to young ear growth, which is the key to growth. After that, with the growth, the ear will be pulled out every 5-7 days or so.

Fourth, after heading in the filling stage, the inside is still dry and not full of fruits. During the period from flowering to grain maturity, the stem will grow taller and the flowers will gradually enrich the grain. This stage determines whether high yield can be achieved, and it is necessary to pay attention to the application of fertilizer.
