What is the cause of the latest blueberry fat damage?

Blueberry has a very large planting area in our country, which is welcomed by many people. The current market price of blueberries is relatively high, and the profit margin is also relatively large, so more and more people begin to plant blueberries. When growing blueberries, they often inflate the fatness and damage of blueberries. Seriously affect the growth of blueberries, so what is the cause of blueberry fat damage? The following editor will give you a brief introduction, let's have a look!

1. Poor quality of fertilizer

When we apply farm manure, we usually give priority to all kinds of faeces. These faeces are very rich in organic matter, and if they are not fully rotten, they will generate a lot of heat and lead to root rot caused by fertilizer and root burning. In addition, when applying organic fertilizer, a lot of fertilizers are used by industrial and agricultural wastes or sludge. Although the labeled amount of these substances can reach the nutrient content of organic matter and nitrogen, phosphorus and potassium. However, many raw materials themselves also contain a large number of heavy metals and other harmful substances, causing serious damage to the roots.

2. Improper chemical fertilizer

In the process of blueberry growth, if ammonium nitrate, phosphorus and potassium and other nitrate fertilizers and chlorine fertilizers are used in the application of chemical fertilizer, it is very easy to cause damage to blueberries. And when many people buy chemical fertilizer, they may ignore the quality of chemical fertilizer and use some inferior chemical fertilizer. The toxic substances in some inferior chemical fertilizers exceed the standard, which can easily cause root rot, yellow leaves and tree decline after use. In serious cases, it will also cause branches and leaves to dry and die, seriously affecting the yield and quality of blueberries.

3. Fertilization is not in the right position.

When fertilizing, we should pay attention to control the fertilization position, if the fertilization position is not right, then the growth of blueberries is also very affected. In the application of chemical fertilizer, if it is applied in holes or ditches, it is too concentrated. Then it will lead to excessive concentration in the region, resulting in root burning death and fertilizer damage. If the fertilization position is too close to the big root of blueberry, then too much fertilizer is generally very easy to cause fertilizer damage, part of the root rot, causing harm to the growth and yield of blueberry.

4. Excessive amount of fertilizer application

The economic value of blueberries is relatively high, and many people are willing to invest. However, when planting, especially for all novices, the misunderstanding of blind fertilization is common. In order to make blueberry trees grow as soon as possible, many people will use excessive fertilization, resulting in too much fertilizer and fertilizer damage. Therefore, when applying fertilizer, we must pay attention to control the amount of fertilizer according to the growth stage of blueberries, not excessive fertilization, to ensure the normal growth of blueberries.

The above is a brief introduction to the cause of blueberry fat damage. That's all for today's introduction. This article is for reference only. I hope it can help you all.
