Currently, the main winter wheat fields in Hebei Province are in the 4 to 5 leaf stage, and are expected to enter the wintering period from north to south at the end of November. In order to actively respond to changes in weather and scientifically carry out field technology management, the Hebei Agricultural Technology Extension Station has joined forces with the provincial wheat industry technology system, the Provincial Meteorological Science Institute and other relevant experts to put forward technical management recommendations based on the analysis of the current seedling conditions in Hebei Province. A solid foundation will be laid for a bumper summer grain harvest next year.
At present, the characteristics of winter wheat seedling situation in Hebei Province are:
The planting area is stable, the variety layout is reasonable, and the high-quality special features are obvious. The summer wheat harvest this year has a bumper harvest. The market price is stable and rising. The price advantage of high-quality wheat is obvious. This has mobilized farmers' enthusiasm for growing wheat. The planting area is stable. In 2020, the autumn planting area will reach 33.1 million mu. The distribution of wheat varieties in the province is guided by high-quality specialization, highlighting the dual improvement goals of quality and benefit, the proportion of high-quality special varieties has further increased, and the variety layout has been more optimized.
The integration of agricultural machinery and agronomy, the implementation of technology, and the steady improvement of planting quality. According to local conditions, the province has carried out the promotion of key technologies such as deep turning and suppressing grass, fine seeding, and post-sowing suppression. The province’s subsoil tillage area has reached 22.2%, the quality of land preparation has improved significantly, the quality of planting has improved the most, and the suppressed area has continued to expand, laying a good foundation for the promotion of wheat seedlings.
Sow the seeds at the right time, and the seedlings emerge evenly and neatly, and the individual robust groups are suitable. The wheat fields sown in suitable seasons in the province account for more than 80%, and the moisture content of the wheat fields is good. The seeds are large and plump, with strong germination potential, high germination rate, fast and neat emergence, and few lack of seedlings. It grows vigorously, the leaf tillers extend at the same time, the root system is well developed, and the wheat fields planted at the right time have reached 4 leaves and 1 big heart. The basic seedlings per mu are 240,000 to 260,000, and the group is suitable.
For the current and wintering management techniques of winter wheat, experts give the following suggestions:
1. According to different conditions of wheat fields, classified management to ensure safe wintering.
Moisture-adapted wheat fields-moisture-preserving and anti-freezing: After the precipitation on November 16-17, the drought conditions in the wheat fields in the central and southern regions were effectively alleviated, and the area of ​​moisture-adaptable wheat fields increased. For plots with a relative soil moisture content of more than 70%, hoeing measures can be taken to further bridge the cracks, increase the temperature and protect the moisture, and no longer be filled with frozen water.
Low-moisture wheat fields-well irrigated frozen water: For wheat fields that still show insufficient moisture content after rainfall, they should be irrigated in time. The amount of water should be filled with bottom moisture and irrigate thoroughly. The time can be controlled before and after the light snow solar term. Daily average temperature 3 It is carried out when the temperature is around ℃, day and night.
Late sowing wheat field-increasing temperature to maintain moisture: for late sowing, the soil moisture is good without watering frozen water, try to use the accumulated temperature before winter to promote the growth of wheat seedlings. If there is a serious lack of moisture before overwintering, water can be properly watered to ensure a safe overwintering.
Siberian pine wheat field-reasonable suppression: For wheat fields with many pine and stubble soils that have not been suppressed after sowing, choose a fine weather in the afternoon before the surface moisture is suitable and the soil is frozen to suppress the soil, stabilize the soil, increase moisture and heat preservation, and prevent frost damage.
2. Carry out chemical weed control in a timely manner.
Wheat fields above 3 leaf age: when the average daily temperature is higher than 8 ℃, choose sunny and windless weather, and remove after 10 am to 3 pm. Choose appropriate drugs according to the types of weeds, and strictly follow the instructions for use, so as not to re-spray, not miss the spray, and spray evenly. Avoid medication during the cold air intrusion stage. The lowest temperature is lower than 4℃.
Untillered wheat field: Wheat fields less than 3 leaf age without tillers and secondary roots should not be sprayed with herbicides to avoid phytotoxicity. Weeds can be treated in spring after returning to green.
High-quality special wheat fields: High-quality strong gluten wheat varieties are sensitive to herbicides, so you must first try them on a small area and apply them after safety tests. Methsulfuron-methyl and its compound preparations are prohibited from strong gluten wheat, and cannot be mixed with 2,4-D to avoid phytotoxicity.
3. Take measures to prohibit grazing in wheat fields.
When livestock eat wheat, the rate of seedling death has increased significantly, which has a serious impact on the turning green and yield of wheat. Wheat fields with large populations and high seedlings can easily cause livestock to eat. Therefore, we should attach great importance to them and take effective measures to strictly prohibit grazing in wheat fields.
