The technical point of management of millet field

First, do a good job in the management of jointing and booting. When the seedling height is about 30cm, the first fertilizer is combined with the cultivating, and the urea is applied at 10 kg/mu; the second fertilizer is used during the booting period, and the urea is applied at 15 kg/mu. The water is poured in time after topdressing, and it can also be combined with rainfall. Deeply ploughed after the jointing of millet, the depth is more than 15 cm. It can loosen the soil, receive rainwater, remove weeds, cut off some old roots, and promote deep roots. From the jointing to the heading before the combination of the second and third cultivating soil, increase the resistance of the millet in the late stage of development, the height of the soil is 10 cm. Pay attention to the prevention and control of the heartworm. When there is a dead seedling in Gutian, timely use high-efficiency, low-toxicity and low-residue pesticides, such as 90% of trichlorfon 800 times or 80% of dichlorvos EC 1000 times.

Second, the flowering period of the millet should be preserved. The flowering stage of millet is the third generation of armyworm. In the application of insects and insects, it is necessary to pay attention to the protection of the flower, and at the same time master the spraying time and dosage. Most of the millet blooms in the middle of the night, so you should never spray in the morning or in the morning, otherwise it will damage the flower and affect the fruit. According to the law of nighttime activity and overeating of armyworms, it is necessary to apply the medicine in the evening so that the medicine is easily adhered by the stems and leaves. For the control of 3rd instar armyworms, 4.5% of beta-cypermethrin can be used in 40-50 ml per mu, or 40% of chlorpyrifos 50-60 ml can be sprayed evenly on 50 kg of water.

The third is to actively take measures to prevent lodging and prevent floods. Linyi Fertilizer Network Copyright

(1) Anti-floating millet enters the filling period, and it is easy to cause lodging when encountering wind. Therefore, spraying phosphorus fertilizer at the heading and flowering stage has a significant effect on reducing the rate of glutinous rice, increasing the 1000-grain weight, and has a strong stalk anti-falling effect. Generally, 40% of the superphosphate leaching solution is sprayed per acre for 40-50 kg. If lodging occurs in the later stage, it is necessary to organize the manpower to raise it in time, and pay attention to starting from the opposite side of the lodging direction, bundle the small handle, and expose 2-3 functional leaves at the top to reduce the loss.

(2) Spraying phosphate fertilizer outside the roots from the heading to the filling stage is an important measure to prevent the glutinous rice. The method is to use 400-500 times potassium dihydrogen phosphate solution, 80-100 kg per mu, sprayed in the afternoon. It has a significant effect on reducing the number of grains in the valley.

(3) If the water shortage during the drought-preserving and flood-preserving filling period will affect the pollen development and reduce the amount of pollen, it is not conducive to fruiting. If a drought occurs, that is, “slow autumn drought”, the grain weight will be reduced and the grain will be increased. Therefore, there are agricultural shoals that “the drought is not a drought, and the autumn drought is reduced by half”. In the case of drought, light watering or inter-watering is adopted to reduce the temperature in the field and increase the humidity, which is conducive to flowering and pollination. Where there is no watering condition, spray water can be sprayed or the amount of liquid can be increased when spraying fertilizer. Millet is also a drought-tolerant and impatient crop. Before the rain comes, it is necessary to organize manpower and do a good job in flood control and drainage. When there is too much rainfall, dredge the ditch and drain it in time to facilitate root growth. Linyi Fertilizer Network Copyright
