Millet is also known as millet, and after the shell is golden yellow millet. The millet has a short growth period, wide adaptability, drought tolerance, resistance to thinness and strong resistance. It is not only one of the main food crops for the cultivation of dry farming in the north, but also a good crop for disaster prevention and avoidance in the southern rivers and beaches.
The main points of cultivation techniques are as follows:
1. Selection of good varieties: There are early, medium and late-maturing varieties in the millet. The growth period of early-maturing varieties is 60-100 days, the medium-maturing varieties are 101-120 days, and the late-maturing varieties are more than 121 days. In our province, it can be spring or summer, and the southern region can also be used for autumn. Generally, late-maturing varieties are selected for spring sowing, medium-maturing varieties are used for summer sowing, and early-maturing varieties are used for autumn sowing.
2, fine land preparation: millet seeds are small, 1000-grain weight 3-3.2 grams, the root buds at the beginning of hair roots are weak, the soil needs to be finely divided, smooth, and solid, to be finely ploughed and flattened, the car is 230cm wide, and the width of the compartment is wide. 20cm.
3, reasonable fertilization: Although the millet is more resistant to thinness, but to win high yield, it must be rationally added fertilizer. Generally, for every 100 kg of grain produced, it is necessary to absorb 3 kg of pure nitrogen, 1.5 kg of phosphorus pentoxide, and 3 kg of potassium oxide. The seedling stage requires less fertilizer, and the jointing to heading stage is the first peak of the fertilizer absorption, and the flowering to grain filling period is the second peak of the fertilizer absorption. The yield per mu is 400 kilograms. It is necessary to apply 2000 kilograms of farmyard manure, 40 kilograms of superphosphate, 10 kilograms of potassium fertilizer, and 10 kilograms of urea after jointing.
4. Appropriate sowing: Determine the appropriate sowing date based on fertility characteristics and meteorological conditions. The seedlings of the millet need to reach a surface temperature of 11-12 °C, and the soil moisture is 60-80% of the field water holding capacity. The heading and flowering period requires sufficient light, and the temperature is 22-25 °C. Below 15 °C, it cannot bloom normally. The spring sowing in the province should be in the middle to late March to the beginning of April, and the summer broadcast in the middle and late June, so that the flowering period avoids the high temperature season in early August, and the autumn broadcast is in late July or early August to ensure flowering pollination before the cold wind. . The sowing method can be carried out by seeding or spreading. The seeding amount per acre is about 1.5 kilograms, the density of seedlings per acre is 3 to 3 million in spring, and about 40,000 in summer and autumn. Grab the sowing, especially in summer and autumn, when it encounters drought, it is necessary to fight drought and soothe.
5, due to seedling management: 3 leaf stage morning seedlings, lack of seedlings timely germination replanting or shifting dense, 5-6 pieces of leaves fixed seedlings, cultivating weeding 2-3 times; jointing period to see the appropriate amount of top dressing, the heading flowering period, In case of drought, watering or foliar spraying should be carried out in time, pay attention to prevention and control of pests and diseases, prevention and control of white onset at seedling stage, control of ash mites at jointing stage, prevention and control of smut at heading stage, sagging of stalks, yellowing of husks and transformation of granules Hard to harvest in time.
