The core of this technology is biogas residue nutrient soil, biogas slurry soaking seedlings, non-woven cover, suitable for the cultivation of machine inserted seedlings with leaf age of 3.5-5.0. The technical points are as follows: 1. Seedbed selection Choose convenient and convenient irrigation, leeward sunny, convenient and easy to use the fertile loose vegetable garden or cultivated mature dry land for seedbeds, acres transplant seedlings bed 6-8 square meters, according to 2 meters open the car preparation, the car surface net width 1.4-1.5 Meters, 0.1 meters high box car, flat car surface, the same height, no sag, no debris, drains around the seedbed to settle, boring bed flat, solid, straight, light, pay attention to bed soil acid. 2. Biogas Slurry Fertilizer Bed and Nutrient Soil About 25 days before sowing, 15 to 25 kg of supersulphate and 250 g of superphosphate were applied per square meter of seedbed and then covered with thin-film fertilizer bed soil. At the same time, according to transplanting Daemu with 40-50kg of fine soil, 20-30kg of biogas residue, 1kg of urea, 1.5kg of superphosphate, 0.2kg of potassium sulfate and adequate amount of biogas slurry, mix and accumulate, and cover-film fermentation and seedbed nutrition Soil and cover soil. 3. Leveling the seedbed and placing the nutrient soil Before planting, plant the flat surface of the seedbed with a small amount of flattened seedlings, and fill the bottom water (in order to be able to use the "pulp" as the degree). After setting up the bed soil, place a sampan plate on the seedbed (select the machine-specific plastic floppy disk with a specification of 58028030 mm3. 16-20), evenly spread the nutritious soil on the plate, the soil thickness of 2 cm. 4. Apply strong blister agent, pouring sole water Acres with 0.3 kg of dry seedling-type strong hoe agent plus 15-20 kg of nutrient soil, mix well and spread evenly on the nutrient soil on the hoe tray. Fill the bottom water and smooth the surface of the disk so that the soil moisture in the retort is saturated. Complete bed soil disinfection, acid adjustment, fertilization, chemical control and strong seedlings and many other technical links. 5. Soaking with biogas slurry Choose hybrid rice varieties with good quality, high yield, stable yield, and good resistance, and use 1 kg of seed for transplanting into the fields; after cultivating and seeding, use soaked medium slurry before sowing to dilute 1:1 or soak seeds with raw liquid. For 36 hours, remove the rice seed immediately after the soaking and rinse with fresh water to drain excess water. 6. Precision seeding, covering non-woven Seedlings of 70-80 grams of rice seeds (wet-groats) were sowed on each plate, and then sowed in detail, uniformly sowed, and then covered with nutrient soil after sowing. After sowing, a layer of ultrafine film is laid on the sampan plate and then covered with a small shed to cover the non-woven fabric. The stencil is tightly pressed around to facilitate the heat preservation and moisturizing. 7. Seedling management Temperature management: Immediately after the needles are peeled off, the flat film is peeled off, and 2 leaves and 1 non-woven fabric are sealed in front of the heart. Afterwards, the non-woven fabrics are gradually removed according to the weather conditions. Humidity management: sowing to emergence, keep bed soil moist, in order to benefit Qi seedlings. Emergence to 2 leaves 1 heart, generally not watering, such as the bottom water is not drenched, can be properly watered on the cloth; 2 leaf 1 heart to 3 leaf 1 heart, see the seedling timely watering, keep bed moist, prevent blue Blight; After 3 leaves and 1 heart, the water control promotes the roots, keeps the disc soil moist, quits, and turns white, and the seedlings do not curl at sunny noon. 3-5 days before transplanting to control wet seedlings, promote seedling rooting, increase the pull force of the block, and facilitate the rolling and machine insertion. Disease prevention and control: focus on the prevention and control of blight and seedlings. 1 leaf 1 heart, with 70% of the enemy 20% of dexamethasone WP 2.0kg water spray control blight, spray a small amount of water immediately after the spray to prevent injury; planted before 2 to 3 days, with 20% of tricyclazole was sprayed 750 times to prevent rice blast. Composting of biogas slurry: spraying biogas slurry solution or raw slurry of biogas slurry with 1:1 watering and spraying 2 times (1 leaf 1 heart, 3 leaf 1 heart), and the biogas slurry is treated with medium biogas slurry for 3 days and sprayed.
