Millet high yield cultivation techniques
1. Seed treatment. Two to three days before sowing, select sunny noon and spread the grains evenly on the ground for sowing, and soak the seeds three times a day before sowing. In other words, the seeds are first rinsed with water, then the seeds are rinsed with 10% saline, and then the salt is washed with clean water; the selected seeds are seeded with 0.1% of the amount of phosphorus-containing pesticides to prevent and control the underground pests; at the same time, the seeds are used. 0.2%-0.3% of Rhizoctonia species is used to prevent white disease and head smut; 2. Timely sowing. The planting period in northern Shaanxi is suitable for the first half of May, and the planting seasons for South and South Shaanxi and Northern Hebei are suitable for mid-May. 3. Precision seeding. According to the level of soil fertility and production conditions, 0.3-0.4 kilograms of seeds were planted in acres, spaced 33-50 centimeters apart and 6-10 centimeters in spacing. Use rake or mechanical drill. When the seedlings were sowed, they first used a plough to open the ditch, and applied 500 manufu of farmyard fertilizer in the ditch. The urea was 7.5 kg. The plough was then used to mix the fertilizer and then sowed with a rake. When sowing seeds, the poisonous valley with 3-4 times the amount of seeds can be ensured, which can ensure uniform seeding and effectively prevent and control underground pests. 4. Repression after sowing. In northern Shaanxi, the spring drought is windy and the moisture in the sowing layer is insufficient. In addition, the land preparation is rough, the land is large, the gap is large, and the grain buds are easy to "suspend". In order to make the millet germinate early, take root deeply, and emerge with the seedlings, it should be followed with repression. After general sowing, it should be suppressed 2-3 times before emergence. 5. Seedling management. When the millet just emerged, it was found that the broken bar was severe, and the seeds could be soaked with warm water, and then the mixture was stuffed with boring germs, and the germs were immediately sowed through the seed coat. The valley seedlings are slightly larger, and the plots with fewer plants can be transplanted on rainy days. Generally, seedlings are most easily survived by transplanting around 5 leaves. Set the seedlings in a timely manner to prevent seedling shortage. Generally, it is appropriate to set the seedlings at the 3-5 leaf time. If seedlings grow more vigorously, seedlings should be repressed in the afternoon. 6. Jointing and booting period management. When the seedling height is about 30 centimeters, it is combined with the cultivator to recover the first fertilizer, and Mushi urea is 10 kilograms; the booting stage is followed by the second fertilization, and Mushi urea is 15 kilograms. It is best to combine fertilizers with rainfall. After the millet is jointed, it is deeply cultivated and has a depth of 15 cm or more. It can loosen the soil, receive rainwater, eradicate weeds, cut off some old roots, and promote the deep rooting of new roots. Jointing to the heading before combining the second and third cultivators. Earthing height 7-10 cm is appropriate. 7. Heading maturity management. The heading and flowering period management should focus on flood prevention, fall prevention and flood prevention. Drain the water in time, cultivating loose soil and improve soil ventilation. After entering the filling period, the panicles gradually increase, and in case of wind and rain, it is easy to fall down. Loosen immediately after lodging, avoid squeezing and shading each other, reduce valleys, and increase grain weight.
