How to plant millet to achieve high yield?

1. Seed treatment. 2-3 days before sowing, seeds are evenly scattered on the ground at noon on sunny days, and the seeds are treated with "three washes, one stuffy and one mixed" the day before sowing. That is, clean water is used to remove chafed seeds, then 10% salt water is used to remove full seeds, and then clean water is used to wash the salt; Seed dressing with 0. 1% internal phosphorus pesticide to control underground pests; At the same time, seed dressing with 0.2%-0.3% of seed quantity can prevent white disease and smut; After seed dressing, pile it for 6- 12 hours before sowing.

2. Sow at the right time. The suitable sowing date is early May in northern Shaanxi, and mid-May in southern Shaanxi, southern Shaanxi and Weibei.

3. Sow accurately. According to the soil fertility level and production conditions, sow 0.3-0.4 kg per mu, with row spacing of 33-50 cm and plant spacing of 6- 10 cm. Use polonium drilling or mechanical drilling. When drilling a hole with polonium, firstly, plow the furrow, apply 500g of farm manure and 7.5kg of urea into the furrow, then mix the fertilizers evenly with the plow, and then drill the hole with polonium. When sowing, 3-4 times of poisonous particles are mixed into seeds, which can not only ensure uniform planting, but also effectively control underground pests.

4. Repression after broadcasting. Spring in northern Shaanxi is dry and windy, and the sowing layer is short of water. Coupled with rough land preparation, more land and large gaps, grain buds are easy to "hang dead". In order to make millet germinate early, take root deeply and emerge evenly, it should be suppressed with the seeds, generally 2-3 times from sowing to emergence.

5. Seedling management. When I first came out of the grain, I found that the broken strip was serious. Seeds can be soaked in warm water, then mixed with drugs to accelerate germination, and sown immediately after the germ breaks through the seed coat. Fields with slightly larger seedlings and fewer plants can be transplanted in rainy days. Generally, rice seedlings are most likely to survive when transplanting about 5 leaves. Seedlings should be fixed in time to prevent lack of seedlings, and seedlings should be fixed as soon as possible in fields with too much sowing. Generally, 3-5 leaves are more suitable for seedlings. If the seedlings grow vigorously, they will be suppressed in the afternoon.

6. Management of jointing and booting stage. When the seedling height is about 30 cm, combined with the first fertilization in intertillage, urea10 kg is applied per mu; Topdressing the second fertilizer at booting stage, and applying urea 15 kg per mu. It is best to combine rainfall with topdressing. After jointing, millet is deeply ploughed, the depth is more than 15 cm, which can loosen soil, receive rainwater, eradicate weeds, cut off some old roots and promote new roots to be deeply rooted. Combine the second and third intertillage till jointing to heading. 7- 10 cm height is suitable for digging.

7. Title maturity management. The management of heading and flowering period should focus on flood control, lodging prevention and chaff prevention. It is necessary to drain water in time, loosen the soil through intertillage and improve the ventilation conditions of the soil. After entering the grouting stage, the ear gradually becomes heavier and prone to lodging in case of wind and rain. Hold the railing in time after lodging to avoid mutual squeezing and shading, reduce glume and increase 1000-grain weight.
