How to manage wheat in the later stages of growth? What are the precautions?

The main common pests in the late growth stage of wheat include aphids and red spider mites. In very few areas, wheat midge, leaf miners, armyworms, etc. are found. Among them, aphids and red spider mites are the main ones that occur in large areas and cause serious damage. , is also the main cause of premature yellowing of wheat leaves. It must be observed frequently. Once the control indicators are reached, spray pesticides in time. In the later stages of wheat growth, the relative soil moisture content is required to be maintained at 70% to 80%, and it must be guaranteed to be above 65%. From the heading stage to the filling stage, water should be sprinkled to replenish moisture in time to avoid drought.

For plots lacking fertilizer, apply 5-7 kilograms of urea per acre along with watering, and spray potassium dihydrogen phosphate on the leaves around May 15. For high-yielding wheat fields without premature senescence, Generally, nitrogen fertilizers are no longer applied. For wheat fields that may become green and mature late, do not apply nitrogen fertilizers. Watering should be carried out according to weather conditions, and the land should be irrigated thoroughly to ensure that the land is fully hydrated. Watering is not allowed in strong winds and heavy rains to prevent wheat from lodging, and the wheat field must not be too dry

Key points in wheat management in the later period, prevention and control Pests and diseases.

Water at the right time and do "one spray to prevent multiple diseases". Pay attention to lodging in the later stages of wheat, because once lodging will have a great impact on quality and yield. There are many factors that cause wheat lodging, such as strong winds and heavy rains, pests and diseases, etc. Therefore, timely measures must be taken. Although some cannot be prevented, losses can be minimized.

The best prevention is pesticides. Nowadays, we are in modern cultivation. We basically take all the precautions that need to be done. In fact, it is quite easy to manage. The field management of wheat in the middle and late stages should be to "stabilize the number of ears and promote grains." number, increase grain weight, maintain quality, prevent lodging, and prevent premature aging", adapting measures to local conditions and seedling conditions, and highlighting classification guidance. Potassium dihydrogen phosphate can be sprayed from the booting stage to the flowering stage of wheat to enhance the wheat's ability to resist dry and hot winds. Watering can be done 3-5 days before the occurrence of dry and hot winds to reduce the damage of dry and hot winds.
