In view of the characteristics of wheat spring seedlings and soil moisture, the theme of early spring wheat field management is to promote tillering, to strengthen seedlings, and to compete for groups. In the specific measures, we should take the seedlings as a starting point, properly operate the fertilizer and water, do a good job in classification management, and realize the transformation and upgrading of the seedlings as soon as possible. Grasping the spring spring technology management, we should master the following aspects:
1. Management of water-deficient wheat fields. That is to say, the wheat field with less than 60% water content in the plough layer must be watered before and after the wheat is returned to the green, combined with watering for topdressing. Generally, the urea is 10 kg to 15 kg. According to the situation of the seedlings and the fertilization situation before the year, the amount of fertilizer was appropriately adjusted.
2. Two or three types of wheat field management. The second and third types of wheat fields with small groups and weak individuals but able to return to normal are mainly cultivating before and after re-greening, and they should be shallow and fine. In the management of water and fertilizer, it is necessary to postpone the spring water for the early spring to return to the green. Generally, after the soil is frozen, it can be watered. Combined with watering, the average mu is about 12 kg to 15 kg. This can consolidate the tillering before winter, promote spring tillering, strengthen the root system, increase the leaf area coefficient, thereby achieving the purpose of increasing the number of groups and increasing the number of ears per mu.
3. A type of seedling wheat field management. For a kind of strong seedling wheat field with good sensation, the management should be deep ploughing in the greening period, control the ineffective tillering, reduce the nutrient consumption, and if the lyrics allow, the spring water can be postponed, and the period to the late stage or early jointing, combined with watering Chasing urea from 10 kg to 12 kg.
4. Control pests and diseases. In early spring, the control of wheat pests and diseases is focused on sheath blight, red spiders and weeds in wheat fields. According to the basic characteristics of the ecological structure of early spring wheat, the focus is on the protection and utilization of beneficial organisms in wheat fields, based on agricultural control, supplemented by chemical control.
5. Optimized cultivation of high quality wheat fields. This year, the area of ​​high-quality and strong gluten wheat in our city has reached 2.8 million mu. In the early spring management, it is necessary to implement the optimal cultivation and cultivation measures. According to the influence of environmental conditions such as water and nutrients on the variety, the following technical aspects should be paid attention to in the early spring management: First, promote water-saving and saturated irrigation technology, reduce the number of watering, and pour the key water. The second is to apply nitrogen fertilizer as little as possible in the early spring, and the land with sufficient base fertilizer is generally chased during the jointing period. The third is to eliminate weeds. Other management measures are basically the same as for ordinary wheat.
