The quality of high quality wheat is controlled by genetic factors as well as environmental conditions and cultivation techniques. In particular, nitrogen fertilizer and moisture have the greatest impact on quality, followed by climate and soil conditions. Phosphorus, potassium, trace elements, crop rotation, pests, lodging, ear sprouting and other factors also have a certain impact. Below, according to the characteristics of high-quality wheat to talk about how to do a good job in field management. First, increase nitrogen fertilizer, balanced fertilization 1. Nitrogen fertilizer use. Rational application of nitrogen fertilizer is an important means to increase wheat yield and quality. (1) Application amount of nitrogen fertilizer: According to the study, when 25 kg urea (containing 11.5 kg nitrogen) was applied, grain yield, protein content, and lysine content were the highest. (2) Nitrogen fertilizer application period: Nitrogen application at the late growth stage of wheat not only can significantly increase the crude protein content of wheat, but also increase the gluten content and sedimentation value (increased 2.3% to 4.5%, respectively, 3 to 6.2 ml), and the extension of the dough is increased. Big. Production should be appropriately postponed during the topdressing period, and good results should be obtained from the time of getting up to the jointing stage. Get up to the jointing period, should be poured enough water, combined irrigation irrigation top 10 kg of urea. (3) Nitrogen fertilizer application methods: Tests show that half of the total nitrogen is applied to the soil before the basal fertilizer is sowed, and half is applied as the top dressing in the spring, and the conditions are suitable for spraying in the middle and later stages (Utilizing urea, etc., ammonia should not be used). Nitrogen). 2. Increase phosphorus, potassium, trace element fertilizers. (1) In phosphorus-deficient soils, the effect of applying phosphate fertilizers on production is obvious. Generally, about 7 kg of phosphorus (phosphorus pentoxide) is applied to mu and applied as a basal fertilizer. (2) Potassium application can improve bread quality, increase protein content, and increase sedimentation value. (3) Use calcium and magnesium fertilizers as appropriate. In the case of moderate levels of nutrients such as nitrogen, ammonium sulfate can be supplemented with either nitrogen or sulfur. Second, timely and adequate irrigation Irrigation before heavy light as well, to create growth conditions for the assimilation and accumulation of nitrogen sources before jointing, post-irrigation to ensure the balance of carbohydrate and protein metabolism, to make it grow simultaneously. Guaranteed to get up water, heading water, grouting water, but also according to the specific circumstances of the wheat crop. Third, the prevention of lateral lodging is a taboo for high yield and high quality cultivation. Production can be used to prevent or reduce lodging in some wheat fields that are at risk of lodging. Fourth, pest control 1. The prevention and treatment of rust: First, we must prevent and treat as soon as possible to reduce the degree of harm. The second is that if a certain harm is caused, the use of a large amount of triadimefon and other drug control can easily reduce the quality of the grain. 2. For the control of powdery mildew, it is best to use resistant varieties, because most of the drugs that control powdery mildew affect grain processing quality. If you have an episode, you must also prevent it early. 3. Prevention and control of wheat bran: Mainly control the damage of wheat bran in the ear stage. A 50% anti-incontinence WP for natural enemies and a 40% omethoate emulsion may be used. 4. For severe weedy plots, use 1 gram of DuPont Superstars to spray 40 to 50 kg of water. After jointing, it is necessary to pay attention to the control of pests and diseases. The use of water, such as amine phosphoramid, omethoate, triadimefon and other pesticides, can be used to control red spider, wheat aphid, yellow dwarf disease and powdery mildew. At the booting stage, the defertilizer field plot can be sprayed with 1.5%-2% urea solution plus 0.2%-0.5% potassium dihydrogen phosphate solution for 45kg, sprayed once every 7 days, and sprayed twice. After the flowers were raised, they were treated with 1500 times omethoate or imidacloprid. 5. Timely harvesting of wheat wax to harvest at the end of ripening and timely threshing to prevent sprouting of the ear or mildew in the sputum. According to the variety of single income, single off, alone drying, single possession, single transport, to prevent mixing.
