The second grade of rice planting process

The planting process of secondary rice includes accelerating germination and seed dressing, raising seedlings in seedbed, transplanting rice seedlings and applying thin fertilizer frequently.

1, germination and seed dressing

When planting rice, you should choose healthy, full and disease-free seeds, soak them in clear water for 30-40 minutes, so that they can absorb enough water, improve the germination rate of plants, and then put them in limewater for seed dressing to reduce the chance of disease.

2. Seedbed seedling raising

When raising rice seedlings, a fertile and soft seedbed with good drainage should be prepared, then potassium permanganate or carbendazim solution should be sprayed on the surface of the seedbed to eliminate the germs on the surface, and then rice seeds should be evenly spread on the soil surface and covered with plastic film to promote its rapid emergence.

3. Transplanting.

When the seedlings grow to 7-8 cm, they can be transplanted. Prepare a paddy field that is sunny, loose and breathable and can store water, and then insert the seedlings into the soil according to the row spacing of 20-30 cm. You can wear a seedling divider on your left thumb to help people divide seedlings.

4, thin fat and diligent application

When cultivating rice, it is necessary to topdressing compound fertilizer and organic fertilizer at the plant growth stage to promote its vigorous growth, make rice seedlings grow healthily and promote the fullness and quantity of rice quality in the future. After heading, potassium dihydrogen phosphate or foliar fertilizer should be sprayed on rice leaves.

Conditions for growing rice:

1. Rice is suitable for growing at higher temperature. The higher the temperature, the faster the growth and the higher the yield. The environmental temperature of rice growth must be higher than 13℃, and when the temperature is lower than 13℃, rice will stop growing.

All green plants grow and nourish under light conditions, and rice is no exception. Rice grows normally under light conditions. When natural light is 50%, rice grows slowly. When the light intensity drops to 5% of the natural light intensity, rice will stop growing or even die.

2. The growth of rice needs enough water. When the water supply is insufficient, the physiological function of plants will be reduced. The tillering stage of rice is the peak of rice water demand, and water shortage is absolutely not allowed.

Rice also needs sufficient nutrients during its growth. Under the premise of conventional rhizosphere fertilization, urea, ammonium sulfate or green manure are applied to fertilize the leaves to help rice grow and resist the adverse effects of the external environment.
