1, pouring enough water to improve the quality of land preparation The bottom is the basis, and the site preparation is the key. Seven minutes and three minutes are the summary of the experience of wheat production stably for many years. In recent years, farmers have looted a large area, coupled with shallow rotary ploughing, laying a great deal of hidden danger for the formation of frozen wheat damage. Although measures such as flooded headwaters and full moon water were used, they played a good role in soil compaction and antifreeze. However, due to the high temperature at the time of irrigating the soil, a large number of cracks were formed in the soil, and farmers were reluctant to plan and the evaporation amount was large. The frozen water must also be filled with water, so it is better to have enough water for late sowing so that only frozen water can be poured, and even most of the land can be free of frozen water. 2, Wang Wang Miao It is to do everything possible to control the growth of wheat on the ground. One is that during the winter wheat period, spraying 40 g of paclobutrazol or 0.3% to 0.5% of Chlormequat solution per acre can inhibit plant growth and prevent or reduce the occurrence of frost damage. The second is to suppress the two times, so that the ground part of wheat is destroyed and grows slowly. 3, promote weak seedlings Weak seedlings on the ground are prone to frost damage, combined with pouring winter water, Mushi nitrogen, phosphorus, potassium compound fertilizer 10-15 kg / acre, but also can be used outside the roots of sucrose. 4, pouring frozen water Whether it is a shortage of ground sorghum or early watering of the wheat fields, the overwintering water must be poured, and the frozen and chilled water should be kept in the night, but the late sowing mash is no longer poured into the frozen water. 5, wheat field coverage, to prevent pigs eat sheep lice, etc. Before winter, in dryland wheat rows, 300-400 kilograms of wheat bran, crushed wheat straw, or other plant wastes are applied per acre to ensure soil moisture and frost resistance. After corruption, soils can be improved and fertility can be cultivated. Antifreeze, effective measures to increase production. After winter wheat enters the wintering period, a layer of manure is spread along the ridge (people call it “warm dung manureâ€), which can protect the wind, protect the earth, increase the temperature and prevent freezing, and add nutrients to the young seedlings. The thickness of manure should be 3-4 cm, and manure should be applied to about 5 cars per mu. When the manure is insufficient, the late barley, wheat field, sandy wheat field, and wheat fields sown with weak winter must be covered. 6, the soil around the root Before wintering, when the wheat seedlings are about to stop growing, combined with ploughing and ramming soil, it is possible to effectively prevent winter wheat from freezing; in severely freezing year, the effect is particularly obvious, and the yield can generally increase by 5%-10%. Frost damage remedies The wheat field with no more than 50% dead seedlings cannot be destroyed. In the returning green period and the jointing stage, 10 kg of urea are recovered, which promotes the formation of medium and small pods, guarantees no premature senescence in the later period, and does everything possible to minimize the loss of freezing damage. Wheat winter irrigation pay attention to "three look" 1, see the sky The effect is best when the autumn is scarce and winter cold and drought are the best. Winter irrigation is suitable when the daily average temperature is stable at about 3°C. If it is too early, the temperature is high and the evaporation is very strong. It does not have the effect of storing water and water, and it will cause the young crops to grow long due to sufficient water and fertilizer, and even the jointing before winter. The cold injury will be serious. If it is too late, the temperature will be low and the water will infiltrate. The ground is easy to form ice shells. The farmer said: "It is not necessary to freeze, winter irrigation is too early, night is too late, irrigation is good; only cold, winter irrigation is late," which is scientifically reasonable. 2, look at Insufficient soil moisture content, 5-20 cm soil moisture below 13%, loam below 15%, clay below 17%, or soil relative humidity below 65%, the need for winter irrigation, higher than the above indicators to be slow Irrigation or non-irrigation; rice buckwheat ground wet enough, low ground temperature, flood irrigation should not be flooded, so as to avoid wheat red, yellow, and even dead seedlings, spray, pipe irrigation methods can be taken to facilitate the warming seedlings. 3, see Miao Wheat early sorghum seedlings generally have better bottom tillers, which can be slowly or non-irrigated, with stagnant water, late sowing of buckwheat, short pre-winter growing period, insufficient effective accumulated temperature, and multiple single seedlings, in order to make full use of effective accumulated temperature in the early winter cold and warm gap. In order to promote the procuring of impoverished dishes, it is generally better not to use irrigation unless it is too dry. In addition, we must improve the quality of winter irrigation. Different irrigation quality, the effect of two kinds. The quantity of winter irrigation water is subject to watering. It is advisable for water to seep through on that day. It is necessary to prevent flooding, pressure, drowning, and damage to wheat seedlings due to flood irrigation, and to cut loose soil in due course after winter irrigation to prevent cracking and penetration of compaction. Dead root seedlings; selected sunny and warm weather from 9 am to 3 pm Watering is good; the lack of base fertilizer, weak seedlings, small groups of wheat fields can be combined with winter water, topdressing urea per acre of 5 to 7.5 kg. Winter fertilizer used to promote transformation and upgrading of wheat seedlings. Disclaimer: Some articles in this website have been transferred from the Internet.
