First, the fertilization position
The roots of plants are extended outwards, especially for larger fruit trees. The foundation closer to the trunk is the root of aging, and the absorption capacity is very poor. The roots absorbed by the main tube are distributed in the periphery, so it is necessary to understand this characteristic of the fruit tree. If fertilization is applied, it should be fertilized around the tree and at a certain position from the trunk, so that the effect is better.
Second, according to different types
The growth of roots of different kinds of fruit trees is also different. This must be understood in advance so that fertilization can be carried out with better results. For example, there are some fruit trees, which are rooted deep, and then there are some fruit trees, it is extended to the surrounding.
For the fruit trees that are rooted in the deep, the hard to fertilize is to be dug deeper, so that its roots can be better absorbed, and then for the kind of spread around the four, there must be a certain distance from the trunk. Fertilize the place.
Third, remember to water
Watering after fertilization is very important. If the soil is too dry, the fertilizer can not be well absorbed by the roots. The utilization rate is relatively low, and if the fertilizer concentration is too large, it will affect the roots of the plants, so Be sure to water after fertilization.
Fourth, depth
Pay attention to the reasonable depth of fertilization, because the root has a characteristic, that is, it will extend like a place with fertilizer, so this time fertilization is also to make the roots grow better. If the position of fertilization is deeper, then the fruit tree can be rooted deeper and it will help her to get better winter.
However, if it is usually topdressing, it does not need to be so deep. The topdressing is mainly for the fertilizer effect to be quickly seen, so if you have a depth of 20 cm, you can. In addition, it is also appropriate to spray some foliar fertilizer to delay the falling time of the leaves.
