In late April, combined with deep-turning 400 kg of organic fertilizer per mu (or 1500 kg of farmer's fertilizer after decomposing), potassium sulfate-type controlled release fertilizer 27-8-10 (N16% controlled release) or potassium sulfate controlled release fertilizer 26- 5-9 (N8% controlled release) 35 kg after the flat.
Third, seed treatment
According to the 1 kg seed per acre, 2.5% flavonoid nitrile (School) 20 g water with 100 ml seed dressing, planted in the shade.
Fourth, sowing
In the first half of May, depending on the soil moisture, it is suitable for sowing. If the sensation is insufficient at the time of sowing, the 1-2 days after the sowing, the germination water should be moderately poured, 20-30 square meters per mu, which promotes the germination of the dry rice seeds to ensure the seedlings are full. Indica rice varieties have strong tillering power, and the amount of seeds used per mu does not exceed 1.5 kg. Advocate machine broadcast. The line spacing is 40 cm, the grain is 5 cm, and the seeding depth is 2-3 cm. At the time of sowing, apply potassium sulfate type controlled release fertilizer 27-8-10 (N16% controlled release) or potassium sulfate type controlled release fertilizer 26-5-9 (N8% controlled release) 15 kg per acre, open on the side of the sowing row.

V. Integrated pest control
(1) Weeding before seeding after sowing. Each acre is selected from 330 g / liter of pendimethalin 200 ml + 50% chlorpyrifos 100 g water 30 kg spray.
(2) Pest control. Prevention-oriented, integrated prevention:
Seedling stage (3-4 leaf stage) pests and diseases mainly have sheath blight, borer, leaf curler, can use 20% Jinggangmycin 50g + 3% cypermethrin 200ml + 10% imidacloprid 20g water 30kg spray The tillering stage (from 4 leaves to the ear before booting) is a key period for the control of rice sheath blight.
