Wheat tillering is poor, how to increase wheat tillering?

Wheat tillering is a key link in the growth and development of wheat and is of great significance for improving wheat yield. However, in the actual planting process, farmers often encounter the problem of poor wheat tillering , which seriously affects the yield and quality of wheat. So if wheat tillering is poor, how to increase wheat tillering? Let’s take a look below.

1. Analysis of the causes of poor wheat tillering

1. Variety factors

There are significant differences in tillering ability among wheat varieties. Winter varieties have relatively strong tillering ability due to the long vernalization stage, while spring varieties have weaker tillering ability. Therefore, it is key to choose varieties with strong tillering ability that are suitable for local climatic conditions.

2. Temperature Factor

The most suitable temperature range for wheat seedling growth is 13-18℃. Temperatures that are too high or too low will affect wheat tillering. Especially when the accumulated temperature is insufficient, wheat tillering will be significantly reduced. For example, late-sown wheat has insufficient accumulated temperature during the growth period, fewer leaves, and less tillering.

3. Soil factors

Soil moisture content and soil fertility have a direct impact on wheat tillering. Soil moisture content between 70% and 80% is most conducive to wheat tillering. Excessive drought or too much water is not conducive to the occurrence of tillering. At the same time, soil fertility, especially the adequacy of nitrogen and phosphorus fertilizers, is also directly related to the quantity and quality of wheat tillers.

4. Seeding amount and density

Excessive sowing amount will lead to crowded wheat plants, small nutritional area occupied by each plant, poor development, thus affecting tillering. Reasonable sowing amount and density are important conditions to ensure good tillering of wheat.

5. Planting depth

Sowing depth is also an important factor affecting wheat tillering. Sowing too deep will inhibit wheat tillering and even cause the seedlings to be weak and difficult to tiller. Generally speaking, the sowing depth of winter wheat should be 3 to 5 cm.

6. Disease factors

Diseases in the wheat seedling stage, such as sheath blight, total rust and root rot, will seriously affect the absorption capacity of the wheat root system and the transport capacity of the stems, resulting in insufficient wheat tillering.

2. Measures to Promote Wheat Tillering

1. Choose the right variety

According to local climate conditions and soil environment, select wheat varieties with strong tillering ability and adaptability to the local environment. Especially for areas that want to increase wheat yields, choosing winter varieties often produces better results.

2. Optimize sowing time and sowing amount

Arrange the sowing time reasonably to ensure that wheat grows within a suitable temperature range. At the same time, determine the reasonable sowing amount according to soil fertility and sowing period to avoid insufficient wheat tillering caused by over-dense sowing.

3. Scientific fertilization

Reasonable fertilization is an important means to promote wheat tillering. During the growth of wheat, nutrients such as nitrogen and phosphorus should be supplemented in time to meet the needs of wheat tillering. In particular, the application of nitrogen fertilizer plays an important role in promoting wheat tillering and forming strong seedlings. Generally speaking, 6-10 kg of urea can be applied per mu, and 5-6 kg of superphosphate and potassium chloride can be applied together.

4. Strengthen field management

Through measures such as inter-row cultivation, hoeing, weeding and loosening the soil, the soil aeration and water retention capacity are improved, creating favorable conditions for wheat tillering. Especially for those plots where tillering is insufficient due to soil compaction, inter-row cultivation and hoeing should be carried out in time to improve soil permeability.

5. Reasonable irrigation

During the wheat tillering stage, the soil moisture content should be maintained between 60% and 80%. If the soil is too dry, irrigation should be carried out in time to replenish water; if the soil is too moist, measures should be taken to drain and reduce humidity to prevent root hypoxia from affecting tillering.

6. Disease prevention and control

Wheat seedling diseases are one of the important factors affecting wheat tillering. Therefore, disease prevention and control work should be strengthened, and reasonable pesticide control measures should be taken to prevent diseases from damaging the wheat root system, thereby ensuring normal tillering of wheat.

7. Take remedial measures

If wheat shows insufficient tillering during its growth, the cause should be found and remedial measures should be taken in time. For example, if there is insufficient tillering due to too deep sowing, you can use the "side scratching with a small hoe" method to dig up the soil to fully expose the tillering nodes; if there is insufficient tillering due to insufficient soil fertility, you should immediately dig trenches and apply top dressing.

That’s it
