The steps of rice planting

Accelerating germination and sowing seeds: select high-quality varieties to soak seeds and accelerate germination, and wait for sowing in a cool place when the bud roots grow to 2mm. Raising seedlings: the methods of wet raising seedlings, dry raising seedlings, water raising seedlings and seedling tray raising seedlings can be adopted. Transplanting: it can be transplanting manually or transplanting rice seedlings by machine. Watering: return to green stage, young ear development stage, heading stage, filling stage all need to be watered. Weeding: weeding is carried out according to different types of rice fields sprayed with different drugs.

First, accelerate germination and sow seeds

1. Seed drying: after drying the seed, the water content will decrease, and the respiration of the seed will gradually weaken due to the lack of water, thus inhibiting its growth.

2. Seed selection: select high-quality varieties, full purebred varieties with strong adaptability and certain stress resistance.

3. Seed soaking: generally, rice seed soaking needs disinfection and sterilization, but the seed can not be hurt. Strong chloroform with better disinfection and germicidal effect can be used.

4. Sprouting: put the treated rice seeds into a mesh bag to accelerate germination. After the temperature of the rice seeds rises, the temperature should be controlled at about 30-32 ℃. If the temperature is higher, it should be properly turned and pushed, and the temperature should be controlled at about 25 ℃ after exposing the white and breaking the chest. Attention must be carried out at the appropriate temperature for budding. After the bud root grows to about 2 mm, it can be placed in a cool place, ready to sow.

2. Raising seedlings

The main results are as follows: 1. The methods of raising seedlings are as follows: wet seedling, dry seedling, water seedling and seedling tray.

2. Generally, seedling plates are often used to raise seedlings. First of all, special nutritious soil is prepared. About 100kg of soil, 300g of ammonium sulfate, 300g of calcium superphosphate, 20kg of organic fertilizer and 200g of potassium sulfate are used to mix evenly. Then use 100 kg of nutritious soil, 10 g of dixone, and about 8 kg of water to spray evenly and pile up for 2 days.

3. Transplanting

The main results are as follows: 1. The seedlings can be inserted into the rice field in an orderly manner, and the traditional transplanting method can use transplanting wheels, seedling marks or seedling ropes, etc.

2. When transplanting rice seedlings manually, a seedling splitter is worn on the hand, which can divide the seedlings and is easy to insert into the field. At present, machine transplanting is used.

Fourth, watering

Generally speaking, rice needs to be watered at the green stage, young panicle development stage, heading stage and filling stage.

5. Weeding

The main results are as follows: 1. Rice field sealing agent is generally applied 10 days before transplanting or the third day after transplanting, which can effectively seal the germination of weed seeds in the field.

2. Weeding in direct seeding rice field: spray 40% 40% bensulfan and propachlor about 60 grams about 3 days after sowing.

3. Weedy rice: about 4 days before sowing, about 200 ml of 12% oxazone was applied, and then 53% bensulfan ·benzoyl 60 grams were mixed with fertilizer.

4. Mechanically inserted into the field: spray 40% bensulfuron 60 grams before insertion, then throw about 200 milliliters of 12% oxazone, 53% bensulfan benzoyl 60 grams to mix fertilizer, and about 6 days after insertion, 53% bensulfan benzoyl 60 grams can be used to mix fertilizer.

5, stem and leaf treatment: grass 24 leaves can use 25% pentafluorosulfonamide 60 ml or so, 10% cyanofenoxate 60 ml or so. The broad leaf of sand grass can use about 10% pyrimidine 20 grams, and the older age can be mixed with 48% bentazone 100 ml and dimethyltetrachloride 100 ml.

VI. Control of diseases and insect pests

1. The main diseases and insect pests of rice are rice false smut, rice blast, rice leaf roller, rice sheath blight, drill worm, rice planthopper and so on.

2. About 5-7 days before the break of rice, metamitoxin, aphidione, fluconazole, rice disinfectant, potassium dihydrogen phosphate, organosilicon, tricyclazole and so on can be sprayed for control.
