1. Seedbed preparation: (1) Select a fertile, loose, drained, and convenient vegetable garden or dry land for the seedbed. (2) Seedling fertilization: Mu with 3,500-4,000 kg of decomposing agricultural fertilizer, 90 kg of rice compound fertilizer, 100 kg of normal calcium, 15 kg of potassium sulfate, and 2 kg of zinc sulfate are uniformly poured into a 15-20 cm deep plowing layer, and the water is poured once. (3) Dashing: The width of the beak is 1.4m and the width of the ditch is 30cm. After treatment, the seedbed reaches the requirements of fertilizer, looseness, fineness, flatness and thickness.
2. Prepare nutritious soil: mix 65% of sieved fine soil and 35% of sieved fine feces with 12g of Pu calcium.
3. Seeding: (1) The best time for sowing is between mid-April and mid-April. (2) Mu sowing rate: 30-35 kg. (3) Seed treatment: Use strong chlorine concentrate or carbendazim to soak seeds for 48 hours, rinse with water, then soak in fresh water for 24 hours, and then pick up the seeds and germinate until the seeds are white. (4) Before the planting, the irrigated water will saturate the entire plough layer. (5) Lightly press the seeds with a wooden board after sowing to promote seeding on three sides. (6) cover with nutrient soil, 0.5-1cm thick, once again spraying water, bare seed cover nutrient soil, so that cover species are tight. (7) Soil disinfection: Disinfect and sterilize with 20% Diocesone 15g watered 12kg. (8) Weeding and Insecticide: Weed and sprayed with 25% penoxsulam (Oryzadide) on the stems and leaves of the weeds after one leaf and one leaf, and evenly sprayed with the enemy killed or 3% carbofuran granules mixed with fine soil. , Prevention of underground pests.
4, overturned arch cover: with bamboo arch, arch height 25-30cm, covered with soil compaction after seedbed around compaction.
5. Seedbed management: (1) Covering film: See the green ventilation seedlings, one leaf (about 10 days later), spray 25 kg of seedlings with 25 g of Dixon to 12 kg of water, and shoot up to two leaves. One heart (about two weeks after sowing), on the premise of fully cultivating seedlings, it was selected on sunny days to remove the film. (2) After uncovering the film, water is poured once, then dry and wet one after another, mainly dry, and when the leaf is noon, fill in the evening or in the morning; if there is too much rain, clear the ditches in time to ensure that there is no stagnant water in Putian. 2 The topdressing seedling fertilizer is applied at the 3-leaf stage, the 4.5 leaf stage and the 5.5-6 leaf stage, and the 8-10 kg urea is converted into a 1% solution per acre for pouring and the seedling is washed with water. Eat small meals. 3 5-7 days before transplanting with 75% tricyclazole WP 100 g and 10% imidacloprid wettable powder 40 g watered 40 kg spray, control shoots and rice planthoppers; pull out weeds, with medicine soil Transplanting.
6. Transplanting in the middle and late May, the age of 40-45 days, the height of the seedlings to ensure more than 20cm.
