What are the causes of wheat lodging and the rescue methods

Wheat is a major food crop in the world and is grown all over the world. In the middle and late stages of wheat growth, certain human or natural factors can cause large-scale lodging of wheat, 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, choosing varieties with tall plants, thin and weak stems, lack of elasticity, and poor tolerance to fertilizer and water means that in the middle and late growth stages, the stems cannot bear the weight of the wheat ears, resulting in 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 ⟧7⟧When wheat is sown too shallowly, the plant roots are shallowly anchored, making lodging extremely likely in the middle and late stages. In addition, if the sowing rate is too large during sowing, the field ventilation is poor, and lodging is extremely likely to occur. Similar to a large sowing rate, excessive sowing density can also cause lodging. Therefore, sowing should be carried out reasonably. Sowing should not be too deep or too shallow, and attention should also be paid to the sowing rate and sowing density.

When wheat is sown too shallowly, the plant roots do not penetrate deep into the soil, making lodging extremely likely in the middle and late stages; in addition, if the seeding rate is too high at sowing, the field has poor air circulation and light penetration, making lodging extremely likely; similar to a high seeding rate, excessive planting density can also cause lodging. Therefore, sowing should be carried out reasonably: sowing should not be too deep or too shallow, and attention should also be paid to the seeding rate and planting density.

3. Improper fertilizer and water management

When fertilizing, too little base fertilizer is applied, while the amount and frequency of topdressing are greater, and the application amount of nitrogen fertilizer is too large, which causes the plants to grow vigorously, have too many tillers, lack other nutrients, lose growth balance, and develop lodging. In addition, improper drainage measures in the field mean that when growing in an environment with high soil moisture, the wheat root system is relatively thin and weak, making lodging extremely likely. Water and fertilize scientifically. Fertilization should be mainly base fertilizer, supplemented by topdressing, with a reasonable combination of nitrogen, phosphorus, and potassium fertilizers, and maintaining a certain degree of soil moisture is sufficient. 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 is harmed by pests and diseases during growth, if 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, during planting, pest and disease control work should be strengthened, and pests and diseases should be dealt with in time so as not to miss the best control time and cause irreversible losses.

5. Rescue methods

After wheat lodges, do not lift it up or tie it into bundles. Let it grow naturally and recover slowly. 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 very likely to be triggered, so disease control work should also be strengthened.
