1. Seed treatment. 2 to 3 days before sowing, the grains were evenly spread on the ground at noon on sunny days and the seeds were “washed and stuffed and mixed†on the 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. The amount of 0.2% to 0.3% of Rhizoctonia species is used to prevent white disease and head smut; after dressing, the stuffy stuffiness is soured for 6 to 12 hours.
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 with a spacing of 33-50 cm and a spacing of 6-10 cm. 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, 3 to 4 times the amount of seeds in the poison Valley, can ensure uniform seed, and can effectively control the 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 site preparation is rough, the land is large, the gap is large, and the grain buds are easy to “suspendâ€. In order to make the millet germinate early, deeply rooted, and emerged with the seedlings, they should be repressed with the species, and after general sowing, they should be suppressed 2 or 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. Usually in the 3 to 5 leaf time Dingmiao more appropriate. 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 of 7 to 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.
