1, material preparation
With one kilogram of seed, prepare the following materials:
1.1 Scratch plate: Machine insert special plate 20 pieces.
1.2 Zhuang Qiang agent: "Zhanke Brand" 0.25-0.5 kilograms of drought-strength agent.
1.3 Plastic film: 2.0-2.2m0.012-0.014? Plastic film length 2.5 meters or more.
1.4 Bamboo pieces: 2.2-2.4m 0.03 m bamboo pieces are prepared.
2. Putian preparation
The shallow muddy sand sloping field blocks with convenient drainage and irrigation, sunny leewards, fertile soil, unobstructed growth of seedlings, and convenient transportation were used as paddy fields to prepare the seedbeds for 5-6 。. Before the Spring Festival, depending on the soil fertility in Putian, sufficient organic fertilizer and phosphorus fertilizer were used to fertilize the soil. Before 5 to 7 days before sowing, shallow water was ploughed until the paste was ready for sedimentation. The spare farmland should be ploughed to rotten, cooked, and flat, as far as possible without impurities.
3, seedbed production
3.1 Carried out as the bed: According to the effective seedbed width 150 ~ 4000px to start the car, the compartment width between each compartment is about 1250px, the depth of the car ditch is 10-500px, and the ditch is opened around the paddy field to ensure the water system is open.
3.2 Leveling the car surface: smooth the car surface, fill the semi-trenchy water drying seedbed.
4, place the plate
The nursery bed is laid vertically and horizontally, so that the retort plate and the sampan plate are closely aligned with each other. The floppy splats overlap. The bottom of the screed is close to the muddy surface of the boring machine. The gap is filled with soil to prevent the deformation of the sampan plate. size.
5, add strong tanning agents, loading soil leveling
Take silt from the ditch, and add 0.25-0.5 kilograms of strong tanning agent per acre and mix well into the pan to make sludge till the edge of the pan, then use a sand board to scrape.
6, even sowing
After the water is dry in the pan, the machine inserts 50 grams (1 grain) of each type of dried seeds (dry grain) for each dish, and the batch is quantified.
7, step into the mud
After sowing, the seeds exposed on the mud surface should be stepped into the mud, and then sprayed with 600 to 800 times the content of 70% of the enemy.
8, arch cover film
8.1 Arches: Each 40-inch bamboo strips are arched and the roof of the arches is 40-1500 px high.
8.2 Cover film: Cover it with micro-membrane. The surrounding area of ​​the film shall be tightly pressed with the earth; the mountainous area can be covered with a layer of plastic film before the arch cover film.
9. Manage the bed
9.1 Temperature and Humidity Control: Soaking to the seedling stage is mainly based on heat and humidity control. The temperature in the membrane is maintained at about 25°C. Needles should be peeled off after the needles are green. Emergence to 1 leaf during the 1 heart during the temperature and humidity control, promote root bar, the intra-membrane temperature remained at 25 °C. 1 leaf 1 heart to 2 leaf 1 heart gradually ventilated seedlings to reduce humidity, the intra-membrane temperature remained at about 20 °C.
9.2 Unmasking the seedlings: In the first complete leaf extraction 0.8 ~ 25px gradually remove the ventilation and hardening seedlings. During the sunny day, the membranes are uncovered and the seedlings are kept warm at night. In the rain, the seedlings are not lifted. Unmasking the seedlings should follow the order of uncovering the two ends, uncovering the side, and eventually opening the film.
9.3 Scientific management of water: After sowing, till the 1.5th leaf of seedlings, hold the ditch for half ditch water, keep thin surface water (water depth: 25px) during the 1.5~3 leaves of the seedlings, and dry the ditch and ditch after 3 leaves to carry out water education. Drought tube promotes packing. In the event of a cold spring, irrigation water is used to protect the seedlings. After the temperature is normal, the air is drained. Before the transplanting, 3 to 5 days, irrigation half-groove water-controlled wet seedlings were added to increase the pulling force of the moromi blocks, which facilitates the rolling and machine insertion.
9.4 Top-dressing: The seedlings are planted with 2.5 leaves of “weaning fertilizerâ€, and 500 kg of biogas or perishable defecation water is used against 2.5 to 3 kg of urea. 5 to 7 days before transplanting, “send marrying manure†is applied, and 750 kg of biogas slurry or decomposed defecation water per acre is used against 8 to 10 kg of urea.
9.5 Disease prevention and treatment: When the seedlings grow to 1.5 leaves, they are sprayed with 1000-fold liquid of 3% KCW or 600 times of 70% of Dixon to water evenly to prevent and control Blight. 1 to 2 days before planting, shoots were sprayed with 20% tricyclazole water 750 times to prevent rice blast.
