For orchards, the most important thing is to apply fertilizer in autumn, which can not only supplement nutrients for fruit trees to survive the winter safely, but also lay a solid foundation for high yield in the coming year. However, the fertilization time and amount of different fruit trees and varieties are different, so we should learn the "three look, three selection, three combination". Let's take a look at the principles of autumn fertilization in the orchard.

One, three, look.

1. Look at the tree situation

For the weak fruit trees, it is necessary to increase the amount of fertilizer, while the element-deficient plants should use the corresponding trace elements, which can promote the similarity of the roots of fruit trees to trace elements and effectively control the physiological diseases of fruit trees.

2. Look at soil nutrients

It is necessary to test the orchard soil to understand the content of various nutrients in the soil and to make up for what is missing and how much is missing.

3. Look at the target output for the coming year

Under normal circumstances, the target yield in the coming year is high, and the amount of fertilizer application in autumn should be large, on the contrary, the target is low, it is necessary to reduce the amount of fertilizer application accordingly. As for anyone who sets the target output for the coming year, it can be increased by about 10% and 15% according to the average output of the orchard in the previous years.

Second and third choice

1. Selection of fertilizer varieties

According to the content of nitrogen, phosphorus and potassium in soil and the principle of balance between supply and demand, the suitable compound fertilizer of nitrogen, phosphorus and potassium should be selected to balance the supply of nutrients and ensure the safe and efficient growth of crops. In addition, we should also pay attention to the acidity and alkalinity of the soil and choose suitable varieties.

2. Second, choose the amount of fertilizer.

On the basis of soil tests, it is appropriate to control the amount of fertilizer according to the amount of fertilizer required by fruit trees.

3. The method of three-choice fertilization

Fertilization methods are very important in orchard production and management. Strip ditch application, annular ditch application, radial ditch application and hole application are commonly used in autumn, which are generally suitable for strip ditch application and ring ditch application.

Three, three combination

First, the application of microbial fertilizer should be combined with the application of fertilizer; second, the application of a large amount of chemical fertilizer should be combined with trace element fertilizer; third, fertilization and watering should be combined, which can not only avoid the injury of thick fertilizer to roots, but also improve the utilization rate of fertilizer. to prevent the fertilizer from being better absorbed by the roots.

The above is the introduction of the three principles of fertilization in the autumn orchard. I hope it can help you. If you want to know more about it, please follow us.
