For the fertilization of fruit trees, many fruit farmers do not care, and think that as long as fertilization, the yield of fruit trees will be very good. Do not pay attention to the use of fertilizers, if the fertilizer is not used properly, it will also produce fertilizer, which will affect the yield of fruit trees, and even cause fruit trees to die. Therefore, the use of fertilizer must pay attention to it, then how to use fertilizer properly? What are the symptoms of fat damage?
1, symptoms
If it is fat, it is generally because of the location of the fertilizer, the concentration is not correct. The first thing that affects the roots of the fruit tree is that it turns reddish brown and then gradually dies. If the roots die, the fruit trees will certainly not grow well.
Absorption of nutrients will be affected, and it will affect the flowering of the fruit trees and the leaves, and this effect is likely to be unrecoverable. In severe cases, it may affect the entire yield and may even lead to the death of fruit trees in batches.
2, pay attention to the fertilization position
When you use the fertilizer for fruit trees, you must pay attention to the position. Many newcomers are prone to make this mistake. For example, fertilization is too close to the trunk. At this time, it is easy to cause fat damage. In general, the roots of the fruit trees with absorption are in the peripheral part.
There is a simpler way to look at the projected part of the canopy, probably the location of the root. When digging holes or digging trenches at this location for fertilization, the nutrient absorption of the fruit trees is better, and it can also prevent the occurrence of fat damage.
3, pay attention to the depth of fertilization
This is also very important. First, we must understand where the roots of the plants are grown. Generally speaking, the depth of the soil is about 20 cm to 40 cm, so pay attention to this depth when fertilizing. Do not fertilize the surface of the soil at a distance of ten centimeters. Otherwise, it is prone to floating roots. In this case, freezing damage will occur in winter.
4, pay attention to fertilization methods
Pay attention to the correct method, and start to mention the need to dig trenches for fertilization, but it is not that the direct filling of fertilizer can be done at the bottom of the pit. This should be mixed with fertilizer and soil, and then try again, the top ten cents. It is the soil that does not contain fertilizer.
5, pay attention to understand the characteristics of fruit trees
Fruit trees have different characteristics, and the demand for fertilizers is also different. It is necessary to pay attention to understanding and fertilize according to its characteristics. In addition, some fruit trees have more sensitive elements, such as peach trees, pear trees can not use chlorine-containing fertilizers.
Planting fruit trees, the most important thing is to fertilize, but the implementation of fertilizer is also a lot of attention, such as the amount of fertilizer, fertilizer time and so on. Therefore, fruit farmers must pay attention to the above five points when fertilizing, correct fertilization, rational fertilization, or it will not be good to bring fat to fruit trees.
