Second, do a good job in seed treatment, carry out wind screening and salt water selection on grain seeds, and remove chaff, grass seeds and sundries. Dry the seeds in the shade and then treat them with chemicals to prevent underground pests and white diseases.
Third, broadcast early in time. Sowing begins when the temperature is stabilized over 7℃, mainly by grasping soil moisture. The soil preparation should be fine, the grid should be well trodden and the soil should be evenly covered. If the hard cover is formed in the rain after sowing, break the hard cover with a roller press or other agricultural tools to make the seedlings strong.
Fourth, improve the quality of sowing, for plots with good bottom moisture and poor surface moisture, push off dry soil and sow on wet soil; For plots with poor soil moisture, organic fertilizer should be moistened 1-2 days before sowing, applied into the soil and sown according to soil moisture; If there is drought when the young shoots dig the soil, press the seeds once to improve the water content and ensure the whole seedling. In short, we should do everything possible to save the seedlings once.
Fifth, reasonable close planting, establish a reasonable group structure, generally according to the terrain and soil fertility for reasonable close planting, the principle is flat land, high fertility plots, high density; The density of plots with strong slope and low fertility is relatively low, generally flat and fertile plots, with 35,000-40,000 plants per mu, and plots with weak slope and poor fertility, with 35,000-35,000 plants per mu. First, base fertilizer, mainly farmyard manure, requires 5000-8000 kg of high-quality farmyard manure per mu, which is mixed with calcium superphosphate as base fertilizer and applied to soil in combination with ploughing or ridging.
Second, grow fertilizer. Generally, applying 10 kg of diammonium phosphate and 5 kg of nitrogen fertilizer as seed fertilizer per mu can promote the early growth and rapid development of millet seedlings and meet the demand for nutrients in the growing period of millet.
Third, topdressing: when the height of millet seedlings is 30-50 cm, it is about 6 cm away from the seedling eyes. Ditching depth with hoe or pick 10cm, evenly spreading about 35 kg of nitrogen fertilizer per mu, and then burying the soil for deep application to improve the utilization rate. First, press seedlings early to promote root development. When the seedlings grow to 2-5 leaves, press the seedlings 1-2 times with wood seeds to strengthen the roots.
Second, plant early and plant early, which means "an inch between the valleys is like dirt". Spacing begins when the seedlings are 3 cm high, that is, when the seedlings are 5-6 cm high, they are fixed, and the grass plants leave seedlings without dead seedlings.
Three, three shovel three times, fine shovel three times, do a good job of weeding and loosening soil, and promote root development.
The fourth is rational irrigation. "Waterlogged beans in dry valleys", millet is a relatively drought-tolerant crop, which is generally not irrigated. However, in the jointing and booting stages and filling stages, in case of drought, emergency irrigation should be carried out, and topdressing should be carried out at booting stage to promote large ears and compete for the number of grains, so as to improve the seed setting rate and 1000-grain weight.
Fifth, prevent and control pests and diseases, timely prevent and control armyworm, locust and corn borer in the growing period, pay attention to prevent and control red spider in the drought period, and timely prevent and control rust in the rainy and humid period in the later period. 1, underground pest control.
It is coated with a seed coating agent accounting for 2.5% of the weight of seeds to prevent and control rice borer, Rhizoctonia solani, needle worm, mole cricket, cutworm and grub.
2. Control aphids.
When the number of aphids in the field reaches 500/100 plants, control is started, and pyrethroids or 50% imidacloprid wettable powder is sprayed 2000-3000 times, or imidacloprid wettable powder 1500 times, and the amount of liquid medicine per mu is 40-50 kg.
3. Control the armyworm.
Master the medication under the 3rd instar, and start medication when the 3rd instar larvae are 20 heads /m2. Spraying with 90% trichlorfon crystal or 20% fenvalerate EC for 2500 times.
