Wheat winter management is the basis and key to high wheat yield. Specifically, the following three points must be addressed:
1. Strengthen fertilizer and water management. For the wheat field with insufficient base fertilizer, small groups, and thin wheat seedlings, the topdressing of urea 6-10 kg per acre should be combined with watering to promote the transformation and upgrade of the seedlings and enhance the antifreeze ability.
2. Do a good job of chemical weeding. To seize the best opportunity for chemical weeding in wheat fields before the winter, scientifically control them. Pre-winter weeding is generally conducted at a daily average temperature of around 10°C to prevent and cure broad-leaf weeds such as pigweed, valerian, virginiana, leeks, and wild rapeseed, and sprays 30 kg of tribenuronic acid per acre with 20 g of tribenuron-methyl. Prevention of wild oats, aphid and other grass weeds, can be used per acre with 6.9% Dima horse cream 60-70 ml or Sema cream 25-30 ml, 30 kg stem and leaf spray control of water.
3. Promptly prevent and treat diseases and pests in wheat fields. For wheat fields not seeded with pesticides, 40% phoxim EC can be used to prevent and control underground pests such as cockroaches and helminths; 1500 times solution of phoxim EC can be used for prevention and cure; 12.5% ​​can be used to control sheath blight and 2000 times can be used to control sheath blight. % Triadimefon 600 times for stem and leaf spray control; control of wheat spider 1.8% abamectin 3000 times or 40% phoxim 1500 times spray control.
It should be noted that livestock farms are forbidden to indulge in barley fields, as livestock eating wheat seedlings will damage a large number of leaves and tillers, and the roots will be pulled out, causing dead seedlings, wheat seedlings to feel sick, and freezing injury aggravating, eventually leading to a reduction in production.
