What are the harms of excessive wheat growth? Growers should know early

Wheat is relatively rare in the south, but in the north its status is as indispensable as rice in the south. Wheat cultivation also involves large-scale planting in the north, and although the history of wheat cultivation is very long, many problems still arise, one of which is excessive wheat growth. 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

Excessive growth of wheat is more common in late autumn. 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, resulting in insufficient wheat in spring. Some tillers of excessively growing plants that grow to the later stage basically decrease in number after spring arrives, leading to insufficient tillering, reducing the number of ears per plant, and seriously affecting yield.

2. Freeze damage

This harm mainly refers to 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 growing wheat seedlings accumulate less nutrients. If they are in a low-temperature environment for a long time, freeze damage is very likely to occur. Freeze-damaged 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 problem most likely to occur. Excessive growth without timely management causes wheat to be too dense and tall, with insufficient sunlight inside. This causes plants to elongate too much, have an unstable center of gravity, and poorer elasticity, with completely no resistance to wind, increasing the occurrence of lodging. Lodging also affects plant growth, reduces yield, and causes losses to one's own economic interests.

4. Weakened root capacity

After wheat grows excessively, the nutrients required increase, and the nutrient transport between the plant and roots also becomes imbalanced, causing most nutrients to be transported to the upper plant. The roots lack nutrients, their growth capacity weakens, the number of roots decreases, and nutrient absorption worsens. The nutrients needed for plant growth are insufficient, so normal growth cannot occur, and various problems appear. The most important among them is premature senescence, which also has a considerable impact on yield.

Failing to promptly deal with excessively growing wheat plants will reduce their permeability, causing the plants to be unable to ventilate and exchange air. Humidity in the lower part of the plants becomes too high, making various diseases and insect pests very likely to occur, such as sheath blight. These diseases are all very harmful to plants and are difficult to control, which may cause incalculable losses to wheat. Wheat photosynthesis will also decline, the accumulation of photosynthetic substances in the plants will be insufficient, and quality will be reduced.

The above is a brief introduction to the harms of excessive wheat growth. Everyone should now have a relatively clear understanding. 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 promptly, either by manual pruning or by spraying 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.
