What are the causes of wheat lodging and the rescue methods

Wheat is a major food crop in the world, grown all over the world. In the middle and late stages of wheat growth, certain human or natural factors can cause large-scale wheat lodging, which affects the growth and development of wheat and causes reduced wheat yields. So what are the causes of wheat lodging? What should be done after lodging? Let's take a look at the detailed introduction.

1. Improper variety selection

When planting, if you choose varieties with tall plants, thin and weak stems, lack of elasticity, and intolerance to fertilizer and water, this type of variety cannot support the weight of the wheat ears in the middle and late stages of growth, thus causing lodging. Therefore, when selecting varieties, try to choose varieties with shorter plants, thick and strong stems, good elasticity, and tolerance to water and fertilizer, which can reduce the occurrence of lodging.

2. Improper sowing

When wheat is sown too shallowly, the plant root system is shallowly rooted, making lodging extremely likely to occur in the middle and late stages; in addition, if the sowing rate is too large when sowing, the field ventilation is poor, making lodging extremely likely to occur; similar to a large sowing rate, excessive sowing density can also cause lodging. Therefore, sowing should be done reasonably; sowing should not be too deep or too shallow, and attention should also be paid to the sowing rate and sowing density.

3. Improper fertilizer and water management

If too little base fertilizer is applied when fertilizing, while the amount and frequency of topdressing are greater, and the application amount of nitrogen fertilizer is too large, it will cause vigorous plant growth, too many tillers, lack of other nutrients, loss of growth balance, and lodging; in addition, if field drainage measures are improper and wheat grows in an environment with high soil moisture, the wheat root system will be relatively thin and weak, making lodging extremely likely. Scientific watering and fertilization should be used, with base fertilizer as the main fertilizer and topdressing as a supplement, reasonably matching nitrogen, phosphorus, and potassium fertilizers, and maintaining a certain degree of soil moisture is enough; it should not be too wet, and in rainy weather, drainage and waterlogging prevention should be carried out in time.

4. Pests, diseases, and natural disasters

When wheat suffers from pests and diseases during growth, if they are not controlled in time, it cannot grow and develop normally, and lodging is extremely likely to occur. In addition, lodging can also occur when strong winds and rainstorms are encountered during planting; at this time, it cannot be controlled by humans and is unavoidable. Therefore, pest and disease control work should be strengthened during planting, and pests and diseases should be dealt with in time when they occur, so as not to miss the best control time and cause irreversible losses.

5. Rescue methods

After wheat lodging, do not lift it up or tie it into bundles; let it grow naturally and slowly recover. In addition, during growth, potassium dihydrogen phosphate solution or plant ash solution can be sprayed to promote its growth and grain filling and reduce the yield loss caused by lodging. After lodging, various diseases are also extremely likely to be triggered, so disease control work should also be strengthened.
