Reasons for low yield of spring wheat

Wheat planting is very common in China, and wheat is suitable for growing in cooler places. It is divided into spring wheat and winter wheat, and the area of planting spring wheat is relatively large. When planting spring wheat, the yield is an issue of great concern to everyone. However, many people's spring wheat yield is not very ideal. So what is the reason for the low yield of spring wheat? The following editor will give you a brief introduction, let's have a look!

1. The temperature rises quickly in spring.

At the temperature of 5-20 degrees, spring wheat needs about 1-3 weeks to complete vernalization development. However, if the temperature rises quickly in spring, and the average temperature is higher than 20 degrees, then the development of wheat during vernalization will be hindered. As a result, the tiller of wheat is insufficient, the quality is not very good, and the number of wheat ears will be reduced. As a result, the secondary root is insufficient, the development is poor, the distribution is not deep, and its fertilizer and water absorption capacity becomes weaker. Spring wheat is also vulnerable to drought nutrition, and it is easy to get rid of fertilizer and premature senescence in the later growth stage, which naturally leads to the decline of wheat yield.

2. Climatic reasons

When planting spring wheat, it is generally in the booting filling stage of spring wheat after May-June. If you encounter a hot, dry and windy climate, then the dry and hot wind environment will lead to premature senescence of wheat. If the temperature is too high, it will lead to increased respiration of wheat, resulting in excessive consumption of nutrients. Thus inhibit the absorption and transport of substances in wheat, resulting in wheat small spikes, light grains and other problems, resulting in the decline of spring wheat yield and affect the planting efficiency.

3. Lack of fertilizer and water

In the growth process of spring wheat, many people have the problem of insufficient farm manure or even no application of farm manure. In the application of base fertilizer, it is also directly sprinkled on the soil, and then no more topdressing in the middle and later stage of wheat growth. As a result, the soil organic matter content is insufficient, the fertility is poor, the fertilizer efficiency time period and so on, it is very easy to appear the phenomenon of de-fertilizing. As a result, wheat has premature senescence, small spikes and low yield. And spring wheat is also a kind of water-loving crop, which generally needs to be watered about 5 times during the growth period. if there is a lack of water, then the lack of water and fertilizer will seriously affect the growth of wheat, resulting in weak seedlings, resulting in fewer spikes and grains and reducing yield.

4. Lighting reasons

Light is also the main factor leading to the low yield of spring wheat. When planting wheat, if the permeability is poor, it will affect the growth of wheat, resulting in the normal photosynthesis of spring wheat. As a result, the photosynthetic intensity is low, and most of the nutrients produced by photosynthesis will be consumed by the vegetative growth of wheat. There are too few nutrients in the reproductive organs, resulting in long development time and slow growth of the reproductive organs, resulting in a decrease in yield.

This is a brief introduction to the reasons for the low yield of spring wheat. That's all for today's introduction. This article is for reference only. I hope it can help you all.
