1. Apply jointing fertilizer well and pour jointing water well From jointing to flowering, wheat is a period of large growth in its lifetime. It is a period of vegetative growth and reproductive growth. The roots, leaves, tillers, stems, ears and other organs grow in an all-round way. The population and individuals develop rapidly, and the growth of plants is large. Tillers gradually form ears, and the differentiation and development of florets lays the foundation for the number of ears per ear. It is a critical period for determining the number of ears per mu and the number of per ear. Fertilizer and water are required. Field fertilizer and water management is very important to ensure a good harvest. Therefore, fertilizer and water management should be carried out during the rise period. Fertilization and watering should be done according to the ground and seedlings. Generally, 10-15kg of urea per mu is applied. If there is rainfall, dry wheat fields can be topdressed with moisture. 2. Pay attention to weather changes to prevent cold in spring After the jointing of wheat, the cold resistance is weakened. If the cold spring occurs at this time, the young ears will be subject to different degrees of freezing damage. The wheat ears drawn out in the future will reduce the number of grains per ear and reduce the yield. Prevention and remedial measures for frost damage in early spring: First, water irrigation to prevent frost damage in early spring. Since the heat capacity of water is larger than that of air and soil, watering before the arrival of the cold current in early spring can increase the water vapor in the air near the ground, release latent heat when condensation occurs, and reduce the variation of ground temperature. At the same time, after irrigation, soil moisture increases, soil thermal conductivity increases, and soil temperature increases. Second, the remedial measures after freezing damage in early spring are fertilization and watering. After the wheat is frozen in early spring, quick-acting nitrogen fertilizer and watering should be applied immediately to promote early wheat tillering and small tillers to catch up with large tillers, increase the rate of tillering into ears, and reduce the loss of freezing damage. 3. Comprehensive prevention and control of pests and diseases The middle and late stages of wheat growth are the main periods when many diseases and insect pests occur, which have a greater impact on yield and quality. Mainly include wheat aphid, wheat spider, rust, powdery mildew, sheath blight, head blight, etc. We must make predictions and forecasts and pay attention to the development of diseases and insect pests at any time. If the control targets are reached, the control should be carried out as soon as possible. For sheath blight, 100-150ml of 5% Jinggangmycin can be used per mu, 50-70kg of water, sprayed on the base of wheat stems. Wheat spiders can be sprayed with 0.9% avermectin 3000 times solution and other agents. Wheat aphids can be controlled by spraying with 50% aphid mist wettable powder at 8-10g per mu. Rust and powdery mildew can be prevented and controlled by spraying 30g per mu with 25% Fengpining WP; head blight can be prevented by spraying 75-100g per mu with 50% carbendazim WP. Head blight should be prevented. If there is continuous cloudy weather at the heading stage, use 80% carbendazim superfine powder 50g per mu or 150ml 40% carbendazim gel suspension in water during the wheat heading to blooming stage. 40kg spray, when spraying, focus on the wheat ears and spray evenly. If it rains after spraying, it needs to be sprayed after rain. Disclaimer: Some articles on this website are transferred from the Internet.
