What are the harms of excessive wheat growth? Growers should pay attention

Wheat is relatively rare in the south, but in the north its status is like that of rice in the south, it is indispensable. Wheat cultivation also has large-scale planting in the north, although the history of wheat cultivation is already very long. But there are still many problems that arise, and excessive wheat growth is one of them, excessive wheat growth is extremely unfavorable to growth, and some novice growers often overlook it. So what exactly are the harms of excessive wheat growth? Let's take a look below!

1. Slow greening

The phenomenon of excessive wheat growth in late autumn is relatively common. If excessive growth in late autumn is not managed in time, it will seriously hinder the growth rate of wheat. Delaying the greening stage of wheat will cause a delay of at least about 1 week, making spring wheat insufficient. For some tillers that grow to the later stage under excessive growth conditions, the number of tillers basically decreases after spring arrives, resulting in insufficient tillering, reducing the number of ears per plant, and seriously affecting yield.

2. Freeze damage

This harm is mainly aimed at winter wheat. After winter wheat grows excessively, because the wheat seedlings are still very fragile, their resistance is not strong, they are not cold-tolerant, and the excessively grown wheat seedlings accumulate less nutrients. If they are in a low-temperature environment for a long time, freeze damage is extremely likely to occur. Frozen plants cannot be rescued, resulting in fewer plants and destruction of planting density, which not only reduces yield, but may even affect the growth of other normal plants.

3. Lodging

Lodging is the most likely problem to occur. Failure to manage excessive growth in time causes wheat to be too dense and tall, and there is not enough sunlight inside. This causes the plants to elongate too much, the center of gravity to become unstable, and elasticity to worsen, leaving them completely unable to resist wind, and the occurrence of lodging increases. Lodging also affects plant growth, reduces yield, and causes losses to one's own economic interests.

4. Weakened root capacity

After wheat grows excessively, it needs more nutrients, and the nutrient transport between the plant and the roots also becomes imbalanced, causing most nutrients to be transported to the upper part of the plant. The roots lack nutrients, their growth capacity weakens, the number of root branches is small, and nutrient absorption becomes poorer. The nutrients needed for plant growth are insufficient, so it cannot grow normally, and various problems appear. The most important among them is premature aging, which also has a considerable impact on yield.

5. Increased disease incidence

Wheat plants with excessive growth that are not dealt with in time will have reduced permeability, causing the plants to be unable to ventilate and exchange air, and the humidity in the lower part of the plants is too high, making various diseases and insect pests extremely likely to occur, such as sheath blight. These diseases are all very harmful to the plants and are difficult to control, which may cause incalculable losses to wheat. In addition, wheat photosynthesis will also decline, the accumulation of photosynthetic substances in the plants is insufficient, and quality is reduced.

The above is a brief introduction to the harms of excessive wheat growth. Everyone should probably be fairly clear about it now. The harms of excessive wheat growth are no less than those of various diseases and insect pests. If this situation is discovered, it must be dealt with in time. You can prune manually, or spray an appropriate amount of growth regulators to inhibit growth, etc. However, pay attention to the use of growth regulators to prevent them from also inhibiting wheat.
