First, sowing technology
1. Selection of millet is relatively sensitive to sorghum and should be avoided. Before the election, it was suitable for the plots of legume and solanaceae.
2. The ground is ploughed in autumn and deep, with a depth of 20-25 centimeters. It requires the land to be flat and the virtual reality. Rotate the arable land before applying the base fertilizer, high-yield fields to spread bags of goods chicken manure organic fertilizer 150-200 kg, 20-25 kg of phosphoric acid diamine, fertilizer fertilizer use should reduce the amount of fertilizer.
3. Select good varieties to select millet varieties that are suitable for the region and have passed the national appraisal, such as Henggu No. 10 and Yegu 36. For the sake of simple management, herbicide resistant varieties can be selected, such as Henggu No. 13, Nogu 31, and Nogu 36. Wait.
4. sowing in the middle and late May sowing appropriate planting, spacing 40-50 cm, sowing amount of 0.5-1 kg / acre, sowing depth of 2-3 cm, sowing after suppression, in order to promote seed germination, ensure seedling full seedling , Mu Liumiao 50,000 or so. After spraying, evenly spraying “grain-rich†or “guyou†herbicides can effectively control various weeds and reduce the labor intensity of manual weed control.
Second, field management
1. Preserving the seedlings of seedlings of seedlings that are small in size and contain less energy, in addition to droughts and other reasons, are likely to cause ridges and ridges in seedlings. Therefore, it is necessary to strengthen field management and reseeding seedlings can be carried out when 2-3 leaves are grown. 5 - 6 leaves when the seedlings, Dingmiao.
2. The middle tillage weeding period for the first cultivator, generally after the seedlings or Dingmiao, master shallow, fine hoe to prevent injury seedlings, pressed seedlings; jointing after the second deep cultivator, depth 7-10 cm, can be Loosen the soil and receive rainwater. Before the heading, conduct a third cultivating tillage to improve soil ventilation conditions. The general depth is about 5 cm. It is appropriate to use the cultivator to remove weeds and soil, and the height of soil is 7-10 cm, which is appropriate after heading. The cultivator is no longer cultivated to prevent manipulation of plants and roots, which can lead to premature aging. Herbicide-resistant millet varieties can be controlled at the beginning of weed growth by spraying special herbicides.
3. Top dressing jointing period with the rainfall or water chasing the first time fertilizer, 15 kg of urea per mu, the booting period combined with rainfall or watering chase the second fertilizer, topdressing urea 20 kg per mu.
Third, pest control
1. Diseases mainly include white disease and gluten disease.
White incidence: Due to the low temperature in spring, seed germination in low-temperature soil and slow emergence of seedlings are prone to white disease hazards. White-emerging bacteria overwinter through oospores in the soil, on the surface of seeds, or on raw manure. The oospore survives in soil for 2-3 years and is the main primary infestation source. Prevention of white incidence can be used before sowing with 35% metalaxyl seed dressing seed 0.2% -0.3% seed dressing, in the field when the first saw white tip and acacia head, timely removal of field disease, and bring out of the field Burned or buried deeply.
Rough gluten disease: In recent years, due to the poor resistance of the popular varieties, there has been an increasing trend of damage in some areas. Sowing over dense, heavy rain, heavy dew, and low temperature at low temperatures in the field is conducive to the occurrence of rickets; excessive application of nitrogen fertilizer, clay, low-lying land is heavy. There is a significant difference in disease resistance among different cultivars. Therefore, varieties with strong resistance to gluten should be selected before planting, such as Henggu No. 10 and Henggu No. 13 and so on. At the same time, field cultivation and management should be strengthened, plant density should be reasonably adjusted, and timely irrigation and drainage should be conducted. To avoid partial application of nitrogenous fertilizer, when the leaf spot is first seen in the field, use 2% kasugamycin wettable powder 500-600 times solution or 40% kehongsan emulsifiable concentrate 500-800 times liquid spray at intervals of 5-7 days. Spray 1 time. In order to prevent panicle blasts, special prevention and control of the panicle can be performed at the heading stage.
2. The main insect pests are millet ash (Rinse heartworm), stick insects and so on.
Millet ash: Millet pods are susceptible to damage in the late spring. Millet ash is feathered at the beginning of June in our province. In mid-June, it is the age of adult worms. It is during the growing season of buckwheat. It enters second-generation larvae from late July to mid-August. Hazard period. Available with 4.5% beta-cypermethrin EC or 2.5% deltamethrin EC 1500-2000 times, 90% trichlorfon 800-1000 times, 50% safrole EC or 50% mitarcapine 1000-1500 times , Optionally, spray the base of the millet stalk before the larvae drill it.
Insect armyworm: Use 20% chlorantranilipronamide suspension 3000 times before the third instar larvae, also use 20% fenvalerate EC 1000-1500 times, 4.5% beta-cypermethrin 1000 times or 48% Chlorpyrifos cream 1000 times, optionally spray it.
