Strengthening the winter wheat field management is conducive to the growth of spring wheat to green, laying a solid foundation for the harvest. Check seedlings After the emergence of wheat, the first thing to check is the emergence of seedlings. Any wheat field that lacks seedlings and ridges should be immediately blasted. For the lack of seedlings, the seeding volume is 5~10 kg per mu, the seeding depth is 5 cm, and the post-sowing is flat, so that the original wheat seedlings are exposed to the soil surface; for the light-crop seedlings, the method of subdividing and hand-ditching is adopted. Replanting, covering soil after sowing; for a small number of missing plots, you can take transplants to replant. The winter wheat is usually transplanted after the wheat grows to the three-leaf stage, and is completed before the frost. For the dry land that cannot be emerged due to drought, the drought-resistant seedlings should be unearthed to ensure the cotton seedlings are unearthed, and the seedlings are evenly seeded. seedling. Do a good job in time When wheat wheat seedlings grow from the second leaf to the three-leaf stage, regardless of whether the wheat-based fertilizer is applied or not, it is generally necessary to carry out the wheat seedling fertilizer. Generally, it is necessary to apply human (animal) large manure urine 15~20 or nitrogen fertilizer 15~20 kg. Only by timely topdressing can wheat wheat seedlings grow vigorously. Heavy application of fertilizer to prevent cold When the wheat grows to the five-leaf stage, the wheat farmers must combine the fertilization of the wheat before the pressure of the wheat. Generally, the amount of pigs, sheep and sheep manure should be 50 to 80 liters per mu, and the villages with conditions (natural villages or village groups) should organize the farmers to pick up 300 tons of mud from the pond to 500 ton or burn the ash and ash to 30 ton. It can play the role of wheat wheat seedlings in fattening and cold protection. Farmers should increase the application of some quick-acting fertilizers to promote the balanced growth of large areas of wheat. Strengthen field management The general principle of winter and spring field management is: early seedlings should be refined, late seedlings should be early tube, lack of seedlings should be germinated to replenish, timely hoeing and topdressing, clearing ditch drainage and disease prevention. Wheat wheat seedlings generally require two times of alfalfa cultivating during winter management; the first hoeing (cultivating) is carried out during wheat tillering. At this time, the young roots of wheat seedlings are suitable for shallow sorghum; the second cultivating (grass) is carried out at the peak of wheat wheat seedlings; at this time, the wheat seedlings are large, the wheat seedlings are strong, and the number of stems and leaves of the wheat seedlings has reached the winter tube index. They can properly squat about 2~3 inches; while the peasants are cultivating hoeing grass, they must also do a good job of clearing the ditch, so that once the cultivating hoeing grass is cleared once, once again, the wheat should be fined early. One time, promote the new generation of tillers and consolidate the former tillers; for the late sowing weak seedlings should be early fattening; generally apply 15 kg of ammonium bicarbonate or 5 kg of urea; some fertile seedlings are postponed until jointing and topdressing. Control pests and diseases in a timely manner The focus of wheat in the greening and jointing stage should be to control the early bacterial sources of powdery mildew and rust; in particular, it should pay attention to the prevention and control of sheath blight and midges, pay attention to the treatment of wheat spiders and treat aphids; the focus of wheat heading to filling stage is to control ear mites and armyworms. The key period of adult pests and worms, powdery mildew and other pests. It is recommended that the wheat farmers in each locality should select the pesticides for the prevention and control of pesticides according to the forecasting time of the pests in the local township agricultural technology stations.
