How to grow rice? The detailed steps explained clearly in one go

SummarySprouting and sowing: Select a high-quality variety and soak the seeds to sprout them. When the sprout roots grow to 2mm, place them in a cool place and wait to sow. Raising seedlings: Methods such as wet seedling raising, dry seedling raising, water seedling raising, and seedling tray raising can be used. Transplanting: Manual transplanting or machine transplanting can be used. Watering: Watering is needed during the greening stage, young panicle development stage, heading stage, and grain-filling stage. Weeding: Spray different chemicals for weeding according to different types of rice fields.

1. Sprouting and sowing

1. Sunning seeds: After the seeds are dried in the sun, their moisture content decreases. Due to the lack of water, the respiration of the seeds gradually weakens, thereby inhibiting their growth.

2. Seed selection: Choose plump, pure seeds of a high-quality variety with strong adaptability and a certain degree of stress resistance.

3. Seed soaking: Generally, rice seed soaking requires disinfection and sterilization, but the seeds must not be damaged. Strong chlorine disinfectant, which has a relatively strong disinfection and sterilization effect, can be used.

4. Sprouting: Put the already treated rice seeds into a mesh bag for sprouting. After the temperature of the rice seeds rises, the temperature needs to be controlled at about 30-32°C. If the temperature is relatively high, turn and stir them appropriately. After the white tips break through the hull, the temperature needs to be controlled at about 25°C. Be sure to sprout the seeds at a suitable temperature. After the sprout roots grow to about 2 mm, they can be placed in a cool place, ready for sowing.

2. Raising seedlings

1. The methods of raising rice seedlings include: wet seedling raising, dry seedling raising, water seedling raising, and seedling tray raising.

2. Seedling tray raising is generally commonly used. First, prepare special nutrient soil. About 100 kg of soil, about 300 g of ammonium sulfate, about 300 g of superphosphate, 20 kg of organic fertilizer, and about 200 g of potassium sulfate can be mixed evenly. Then, about 100 kg of nutrient soil and about 10 g of dexon are sprayed evenly with about 8 kg of water, and piled and covered for 2 days.

3. Transplanting

1. Insert the seedlings into the rice field in an orderly manner at intervals. Traditional transplanting methods can use transplanting wheels, seedling markers, or seedling ropes.

2. When transplanting manually, a seedling separator is worn on the hand to separate the seedlings, making it easier to insert them into the field. At present, machine transplanting is generally used.

4. Watering

Rice generally needs watering during the greening stage, young panicle development stage, heading stage, and grain-filling stage.

5. Weeding

1. Rice is generally treated with a field-sealing agent 10 days before transplanting or on the third day after transplanting, which can effectively seal off the germination of weed seeds in the field.

2. Weeding in direct-seeded rice seedling fields: About 3 days after sowing, spray about 60 g of 40% bensulfuron-methyl · pretilachlor.

3. Weedy rice: About 4 days before sowing, broadcast about 200 ml of 12% oxadiazon, and then at the three-leaf-one-heart stage mix 60 g of 53% bensulfuron-methyl · benzothiazolinone with fertilizer.

4. Machine-transplanted main field: Before transplanting, spray about 60 g of 40% bensulfuron-methyl · pretilachlor, then broadcast about 200 ml of 12% oxadiazon, and at the three-leaf-one-heart stage mix 60 g of 53% bensulfuron-methyl · benzothiazolinone with fertilizer. About 6 days after transplanting, 60 g of 53% bensulfuron-methyl · benzothiazolinone can be mixed with fertilizer.

5. Stem and leaf treatment: For 24-leaf grass, about 60 ml of 25% penoxsulam and about 60 ml of 10% cyhalofop-butyl can be used. For sedges and broadleaf weeds, about 20 g of 10% pyrazosulfuron-ethyl can be used. For older weeds, 100 ml of 48% bentazone and 100 ml of MCPA can be mixed and applied together.

6. Pest and disease control

1. The main rice pests and diseases include rice false smut, rice blast, rice leaf roller, rice sheath blight, rice stem borer, rice planthopper, and so on.

2. About 5-7 days before rice heading, emamectin benzoate, pymetrozine, epoxiconazole, isoprothiolane, monopotassium phosphate, organosilicon, tricyclazole, etc. can be sprayed for control. After the rice is in full heading, spray once more.
