Winter Wheat Management Five Points

After checking seedlings to fill the deficits, the first thing to do is to check the emergence of seedlings. Any wheat field that lacks seedlings or ridges should be promptly primed. For lack of seedlings and seedlings, 5 to 10 pounds per mu are sown, and the seeding depth is 5 cm. After sowing, the seedlings are exposed and the original wheat seedlings are exposed. If the seedlings are lacking, the seedlings shall be sown in a subdivision manner. Replanting, covering the soil after sowing; for a small number of plots lacking seedlings, transplanting seedlings can be taken. Replanting winter wheat generally starts transplanting after the wheat reaches the three-leaf stage, and completes the planting before the frost. In dry land that cannot emerge due to drought, it should be excavated from the drought-resistant seedlings to ensure that the cotton is intercropped with whole seedlings, seedlings, and seeds. seedling.

When the topdressing wheat seedlings grow to the time of two-leaf one-to-three-leaf time, no matter whether the sowing wheat basal fertilizer is fully applied or not, it is generally necessary to top-dress wheat seedlings. Each acre is generally applied to humans (animals) 15 to 20 tons of fecal urine or nitrogen fertilizer about 15 to 20 pounds, only through timely dressing, can promote the healthy growth of wheat seedlings.

Reusing wax fertilizer to prevent cold when the wheat grows to the five-leaf stage, the wheat growers must combine the weight of wheat before the heavy fertilizer. Generally, 50 cattle and sheep dung should be applied to 80 metric tons or so per mu, and villages (natural villages or villagers groups) with conditions should be organized to organize farmer households with 300 to 500 metric tons of mud or 30 s , Wheat seedlings can be used to increase fertilizer and prevent cold, farmers should apply some quick-acting fertilizers to promote balanced growth of large areas of wheat.

Strengthen field management The principle of total field management in winter and spring is: early seedlings should be fine tubes, late seedlings should be early tubers, and seedlings must be primed to replant sowing. Winter wheat seedlings generally require 2 times of cultivator cultivating during winter management; the first time weeding (intermediate cultivating) is carried out during wheat delivery. At this time, the young roots of the young seedlings are suitable for shallow boring; the second cultivating (grassroots) is better when the wheat seedlings are at the peak of tillering; at this time, the wheat seedlings are large and the wheat seedlings are strong. The number of stems and leaves of the wheat seedlings group has reached the winter tube index, and the wheat cultivars We can properly squat about 2 to 3 inches; while the wheat growers are cultivating the grass, they must also combine the work of clearing the ditch so that the hoe can be cleared once; once again, the return of the wheat to the green season must be as early as possible. One time, to promote the delivery of new births and consolidate the former delivery; on the late broadcast weak seedlings should be more fertilizer; general Mushi ammonium bicarbonate 15 kg or urea 5 kg; part of the Zhuangwang Miao delayed jointing fertilizer.

Preventing pests and diseases in a timely manner The main pathogens of powdery mildew and rust should be controlled during the jointing stage of the replanting period of wheat; in particular, attention must be paid to the control of sheath blight and midge insects, and the importance should be attached to the treatment of wheat spiders and also the aphids; The critical period of pests and diseases such as adult armyworm, midge and adult rust, and powdery mildew. It is suggested that wheat farmers in various places should select and control pesticides on roads according to the prediction time of pests and diseases at local agricultural stations.
