The rejuvenation stage of wheat is the key stage of wheat growth, and special attention needs to be paid to the management to ensure its steady growth and high yield. You need to pay attention to the weather, rain, and soil fertility at all times, and apply fertilizer in a timely and reasonable manner to prepare for a bumper harvest!
To prevent the impact of spring cold on wheat regreening, the following measures can be taken:
1.Pay attention to the weather forecast: Pay close attention to the weather forecast and know in advance about the possible low temperature weather so that you can take timely measures.
2.Increase mulch: Adding mulch, such as straw mats, plastic film, etc., on wheat fields can reduce ground heat dissipation, keep soil temperature stable, and are suitable for small area planting.
3.Watering and insulation: Watering at the right time before the onset of low temperatures can increase the temperature and humidity of the soil, reduce heat dissipation on the ground, and help protect the wheat from frost damage, which is very important and very effective.
4.Use antifreeze: Plant growth regulators or antifreeze can be used to enhance wheat's ability to withstand cold. These products can be sprayed on wheat before the onset of low temperatures, helping to reduce the damage caused by low temperatures.
5.Reasonable fertilization: Reasonable fertilization can enhance the stress resistance of wheat and make it more adaptable to low temperature environments. Avoid over-application of nitrogen fertilizer, which may lead to vigorous growth and reduce cold resistance.
6.Strengthen pest control: Pests and diseases will weaken the cold resistance of wheat, so it is necessary to strengthen the control of pests and diseases before the arrival of low temperatures to ensure the healthy growth of wheat.
7.Arrange the sowing time reasonably: try to choose the appropriate sowing time and avoid sowing too early or too late to reduce the risk of being affected by the spring cold.
The management of wheat rejuvenation period is very important, and it is necessary to comprehensively consider water, fertilizer, disease, insects and other factors, and pay more attention to the following aspects:
1.Water management: For wheat fields with little or no watering in winter, they should be watered in time after the temperature rises in spring. Watering can not only alleviate drought, but also promote normal regreening of wheat, especially in areas with weak growth, low precipitation and snowfall, or drought that has already occurred in previous years. However, it should be noted that the amount of watering should not be too large, so as not to cause soil water accumulation and suffocation of seedlings. After watering, timely loosening of the soil can increase the ground temperature, which is conducive to the normal growth of wheat.
2.Fertilization: Wheat needs a lot of nutrients to support its growth during the rejuvenation phase. Therefore, according to the growth status of wheat and the fertility of the soil, it is very important to fertilize scientifically and reasonably.
3.Disease control: The regreening stage of wheat is a disease-prone period, especially soil-borne and seed-borne diseases such as sheath blight and stem base rot. These diseases seriously affect the growth of wheat and cause a reduction in yield in the later stage. Therefore, it is necessary to strengthen the prevention of diseases and ensure the healthy growth of wheat.
4.Prevent vigorous growth: Vigorous growth refers to the rapid growth of wheat in the regreening stage, and the stems and leaves are too luxuriant, resulting in uneven nutrient distribution and affecting the normal growth of wheat. In this case, the tillering and heading of the wheat may be affected, thus reducing the yield. Therefore, it is necessary to reasonably control the amount of fertilizer and avoid excessive nitrogen fertilizer to prevent wheat from growing.
In short, the management of wheat rejuvenation is very important, and it is necessary to comprehensively consider water, fertilizer, disease, insects and other factors to ensure the healthy and steady growth of wheat.
