Millet also known as millet, after the shell is golden yellow millet. Millet has a short growing period, wide adaptability, drought resistance, low tolerance, and strong resistance. It is not only one of the main food crops planted in northern dry farming, but also a good crop for disaster relief in the floodplain of the South China Sea. The main cultivation techniques are as follows: 1. Selection of good varieties: There are early, middle and late-maturing varieties in the millet valley. The early-maturing varieties have a growth period of 60-100 days, medium-maturing varieties of 101-120 days, and late-maturing varieties of 121 days or more. In our province, it can be planted in spring, but it can also be planted in summer. In the south, it can still grow in autumn. Generally, late-maturing varieties were selected for spring sowing, medium-maturing varieties for summer sowing, and early-maturing varieties for autumn sowing. 2. Fine soil preparation: Millet seeds are small and the grain weight is 3-3.2 g. The root buds are weak at the beginning of the rooting process. The soil needs to be finely chopped, smooth, and sink. It is necessary to plough more and more rakes, make the flat surface, the width of the cabin is 230cm, and the width of the cabin is wide. 20cm. 3. Reasonable fertilization: Although the millet valley is more resistant to barrenness, it is necessary to increase fertilization material to obtain high yield. Generally, for every 100 kg of fruit produced, 3 kg of pure nitrogen, 1.5 kg of phosphorus pentoxide, and 3 kg of potassium oxide are absorbed. Seedlings require less fertilizer, jointing to the heading period is the first peak of absorption, flowering to the grain filling period is the second peak of absorption. 400 kg per mu should be applied at the end of 2000 kg of farmyard manure, 40 kg of superphosphate, 10 kg of potash, 10 kg of urea topdressing at the jointing stage. 4. Suitable sowing: Determine the appropriate sowing date according to the fertility characteristics and meteorological conditions. Millet seedlings need seedling emergence 5cm soil surface temperature reached 11-12 °C, soil moisture is 60-80% of field capacity, heading and flowering require sufficient light, temperature 22-25 °C, less than 15 °C can not normally flower. Spring sowing in the province should be from late March to early April, summer sowing in the middle or late June, so that the flowering season avoids the high temperature season in early August, autumn sowing in late July or early August, to ensure flowering pollination before the cold wind . Seeding method can be drilled or sowing, sowing rate of about 1.5 kilograms per acre, seedling density per acre seedlings planted 35,000-35, summer planting about 40,000. Robbery sowing, especially in summer and autumn sowing, encounter drought, drought protection and sowing. 5, due to seedling management: 3 leaf stage early seedlings, lack of seedlings promptly reseeding or replenishing replenishment and thinning, 5-6 leaves Dingmiao, weeding 2-3 times; jointing time to see the right amount of seed dressing, heading and flowering period, In case of drought, timely watering or foliar spray, pay attention to prevention and control of pests and diseases, prevention and treatment of white seedlings at the seedling stage, prevention of millet ash at the jointing stage, and prevention of smut at the heading stage; when the ear of the corn is drooping, the husks turn yellow, and the grain changes Hard when timely grab the sunny harvest.
