Causes and Rescue methods of Wheat lodging

Wheat is the main food crop in the world, which is planted all over the world. in the middle and later stage of wheat growth, it will lead to large area lodging of wheat because of some man-made or natural factors, which will affect the growth and development of wheat and reduce the yield of wheat. So what are the reasons for wheat lodging? What should I do after falling down? Let's take a look at the detailed introduction.

1. Improper selection of varieties

The varieties with high plant height, thin stalk, inelasticity and intolerance to fertilizer and water are selected when planting. In the middle and later growth stage, the stem can not bear the weight of wheat ear, which leads to lodging. Therefore, when selecting varieties, we should try to choose varieties with shorter plants, stout stems, elasticity and tolerance to water and fertilizer, which can reduce the occurrence of lodging.

2. Improper sowing

Because the sowing of wheat is shallow, the root system of wheat is shallow, which leads to lodging in the middle and later stage; in addition, if the sowing rate is too large, the field permeability is poor and lodging is easy to occur; similar to the large sowing rate, too high sowing density will also cause lodging. Therefore, sowing should be carried out reasonably, sowing should not be too deep or too shallow, and we should also pay attention to the sowing rate and density.

3. Improper management of fertilizer and water.

When fertilizing, the application of base fertilizer is too little, and the amount and times of topdressing are more, and the application of nitrogen fertilizer is too large, which will lead to exuberant plant growth, too many tillers and lack of other nutrients, resulting in growth loss of balance and lodging; in addition, improper drainage measures in the field, growing in the environment of high soil moisture, the root system of wheat is thin and weak, and is easy to lodge. Scientific watering and fertilization, fertilization based on base fertilizer, supplemented by topdressing, reasonable collocation of nitrogen, phosphorus and potassium fertilizer, to maintain a certain degree of soil moisture, should not be too wet, rainy weather should be timely drainage and waterlogging prevention.

4. Diseases, insect pests and natural disasters

Wheat suffers from the harm of diseases and insect pests during its growth. If it is not controlled in time, it can not grow and develop normally, and it is very easy to lodge. In addition, when you encounter a stormy climate when planting, there will also be lodging, which is unavoidable and uncontrollable. Therefore, the prevention and control of diseases and insect pests should be strengthened when planting, and the diseases and insect pests should be dealt with in time, so as not to miss the best control time and cause irreversible losses.

5. Rescue methods

Do not lift or tie the wheat after lodging, but let it grow naturally and recover slowly. in addition, it can also be sprayed with potassium dihydrogen phosphate solution or plant ash solution during growth to promote its growth and filling, reduce the loss of production caused by lodging, and easily cause a variety of diseases after lodging, so it is necessary to strengthen disease prevention and control.
