Grasp six o'clock wheat fields in the beginning of spring

Water well the first water in spring For wheat fields with poor moisture content, weak seedlings and few total stems in the near future, the first water in spring should be watered until the winter wheat rise period; for wheat fields with good moisture content and strong seedlings, the first water time can be delayed. For wheat fields that have returned to green, water sources should be widely available, and the green water should be poured in time to ensure the normal green growth of wheat. For wheat fields that have not yet returned to green, water them in time to replenish moisture when the daily average temperature stabilizes above 5°C.

To promote the weak and strong, timely topdressing is recommended for topdressing the wheat after getting up and before jointing; for high-yield wheat fields with large populations, the fertilizer and water should be controlled, and then watering at the jointing stage. Combined with watering for top dressing. Generally, 5 to 8 kg of urea per mu is used, and the urea can be controlled below 5 kg under normal conditions for seedlings.

Suppress areas with less precipitation, poor soil moisture, and extensively cultivated wheat fields with a lot of scum, which can be suppressed in the afternoon on sunny and warm weather, crush scum, seal cracks, increase temperature and maintain moisture. For wheat fields with large populations and prosperous growth trends, we must promptly suppress them in early spring to control the prosperous growth and achieve the purpose of preventing lodging.

Chemical hoe spring plants sprout and grow, winter wheat ushered in a new growth period, at the same time, the weeds in the wheat fields have also reached a period of proliferation, growers should seize this opportunity to remove weeds in time to prepare for increasing wheat production.

Actively prevent the "back spring cold" that is prone to staged strong cold air in early spring. It is necessary to strengthen classification management. Promote the early spring suppression of seedlings in the prosperous wheat field in time to achieve growth control and growth; timely topdressing of weak seedlings, reasonable regulation of fertilizer and water, and promotion of seedling transformation and upgrading Improve cold and frost resistance. Irrigate water in time before cooling down to improve soil moisture, adjust the microclimate near the ground, reduce the variation of ground temperature, and prevent freezing damage in early spring. For wheat fields that have suffered freezing damage, apply appropriate amount of nitrogen fertilizer in time and water them in a timely manner to promote the recovery of frozen wheat growth.

Pay close attention to the prevention and control of diseases and insects, focusing on the prevention and control of wheat stripe rust and other diseases and underground pests, timely release of disease and insect information, and timely emergency prevention and control. Support the development of professional plant protection service organizations, vigorously promote unified prevention and governance and green prevention and control, improve prevention and control effects, and reduce pest damage. In areas where disease and insect recurrences occur, joint prevention and control, group prevention and group control shall be implemented to curb the outbreak of disease and insect pests. For wheat fields without chemical weeding before winter, choose sunny weather and implement chemical weeding.
