Winter wheat is the main food crop in Hebei Province. Its annual planting area is more than 36 million mu. The output of winter wheat is closely related to people's lives. In order to ensure the high and stable production of winter wheat, the following ten points must be noted.
1 Chemical seed dressing. Based on the selection of suitable local varieties, seed dressing or insecticide and fungicides dressing is used.
1.1 Total erosion disease. Available 12.5% ​​full eclipse net 20 ml, dilute 1 pound, or 3% enemy force Dan 50ml-100ml plus 2.5% Cola when 20ml, mixed wheat seed 10 kg, with the mix with the broadcast.
1.2 Smut. Available 25% triadimefon 150 ml 0.5 kg mixed with water 50 kg boiled seed, can also be used 0.2% of 70% thiophanate-methyl seed dressing or boring seed; pesticides and fungicides should be mixed when mixing insecticide Agent, followed by a fungicide.
2 The bottom is adequate. Bottom padding is an important prerequisite for winter wheat to achieve full seedling growth. If the seedlings are suitable for the first time, they can be sown and sowed. After the seedlings are sown, they should be sowed. For sowing, it is also necessary to create the principle of "solefoot" and ensure that all seedlings are broadcast.
3 Fine soil preparation. In successive years, the revolving plots should be deep plowed 5-6 inches deep. The straw should be returned to the plots to remove long broken straws. The site preparation must be thoroughly cleaned and smoothed, and the actual conditions should be fulfilled to ensure the quality of the soil preparation.
4 soil testing formula fertilization. Adequate base fertilizer is the material basis for realizing high and stable yield of wheat. It adheres to the principle of "stabilizing nitrogen, reducing phosphorus, supplementing potassium, and matching micro-organisms" based on the return of straw or organic fertilizer, and "the former light, medium, and heavy "The method of fertilization. Promote soil testing and formula fertilization, generally 14-16 kilograms of m pure nitrogen, P2O5 6-8 kilograms, K2O 4-6 kilograms. Phosphorus and potassium fertilizers were applied at the end of one time, 50-60% of nitrogen fertilizer was applied, and 40-50% of nitrogen fertilizer was applied in the second spring.
5 Sowing period. Taking all factors into consideration, the appropriate sowing date for wheat in our province this year will be around October 5-15, and the best sowing date will be around October 7-12.
6 broadcast volume. In the appropriate sowing period, the sowing volume is 9-12 kilograms. According to the characteristics of the variety sowing every night after its suitable sowing date, the sowing rate of the sown mussels increased by 0.5 kg.
7 sowing form. In order to reduce the evaporation of soil moisture during the wheat growing period and achieve water saving purposes, we have promoted the use of row spacing sowing techniques with a row spacing of 15 cm and a sowing depth of 4-5 cm.
8 Crackdown after sowing. The suppression of wheat after sowing is an effective measure to improve the drought resistance and seedling quality of wheat seedlings. After sowing the seeds, it is best to use iron shovels again to ensure that the surface layer of soil, to achieve the next reality. After the end of sowing, hoeing is done. In order to save irrigation water, small irrigators are used for irrigation. According to the conditions of the land, the rake width is 4-5 meters and the length is 7-10 meters.
9 Seedling replanting. Seedlings should be investigated promptly after emergence, and 10-15 cm seedling-free plots in the wheat ridge should be reseeded for seed reseeding.
10 Weed autumn rule. For malignant grass weeds, it is necessary to spray 3-5 leaf stages of wheat and control spraying of weeds at the 2-4 leaf stage. In wheat fields based on bromegrass and amaranth, 3% Shima Oil Suspension 20-30 can be used. Add 60 ml of auxiliaries, mix with 30 kg of water and evenly spray. Use wheat that is dominated by broad-leaved weeds such as sow wormwood, leeks, and wheat grass, etc., and select 10% in the 2-4 leaf stage after unearthing. 10 grams of tribenuron-methyl, or 1 gram of superstars, is sprayed with 30 kg of water; Viruses of mixed virulent grasses and broadleaf weeds can be mixed and sprayed with the corresponding herbicides. Try to choose the weather is fine, the temperature above 10 °C spray, pay attention, the amount of liquid should be sufficient, once sprayed, not heavy spray does not leak spray.
