There are several ways to fertilize fruit trees in autumn, with matters needing attention.

The time of fertilization for fruit trees in autumn is from September to October. Ring fertilizer method: dig an annular ditch with a width of 30-60 cm and a depth of 30-50 cm at the outer edge of the crown, then mix fertilizer and soil evenly in the ditch and cover the soil. Strip fertilization method: according to the size of the crown, 1-2 ditches were opened between the rows of fruit trees, with a width of 50-70 cm and a depth of 30-50 cm, and then mixed fertilizer and soil in the ditch and covered with soil. Note: it should be watered in time after fertilization.

1. The time of fertilization for fruit trees in autumn

September to October is the golden period for fertilizing all kinds of fruit trees. during this period, the appropriate fertilization time should be selected according to different varieties. Generally, early-maturing varieties can be fertilized after fruit harvest, and middle-and late-maturing varieties can be fertilized before fruit harvesting. The period should not be later than one month before the defoliation of fruit trees.

II. Methods of fertilization for fruit trees in autumn

1. Ring fertilizing method

An annular ditch with a width of 30-60cm and a depth of 30-50cm can be dug at the outer edge of the crown, and then mixed with fertilizer and soil in the ditch, and then covered with a layer of soil. This method is suitable for young trees with small root distribution.

2. Strip fertilizing method

The main results are as follows: (1) generally, according to the size of the crown, there are 1-2 ditches between rows or trees of fruit trees, with a width of 50-70cm and a depth of 30-50cm, and then mix fertilizer and soil evenly in the ditch.

(2) cover another layer of soil, and the ditch can be used alternately every year. This method is suitable for fruiting trees, which should be watered once after fertilization, which is beneficial to the close connection between soil fertilizer and root system.

Matters needing attention for fertilization of fruit trees in autumn

1. Fertilizing and opening ditches should not be too shallow, otherwise it is easy to cause root floating, which will affect the drought and cold resistance of fruit trees.

2. The original ecological organic fertilizer must be fully mature, and raw chicken manure and sheep manure should not be directly applied during this period, otherwise the roots of fruit trees will be burned, resulting in tree weakness, death or rot.

3. For the plots with good water conservancy conditions, generally watering should be carried out after fertilization, which is helpful to promote the root system to fully absorb nutrients.

IV. Benefits of fertilization for fruit trees in autumn

1. Fertilization in autumn can supplement a large amount of nutrition consumed by the growth of fruit trees in time, which is beneficial to continue to promote flower bud differentiation, and the temperature in autumn is suitable, the light is more sufficient, and the root absorption capacity of fruit trees is also stronger. fruit trees can absorb nutrients to a large extent, and then store nutrients in the tree body, which is beneficial to enhance the tree potential and reduce the occurrence of frostbite and rot.

2. At the same time, it can ensure that in the spring of the second year, there is sufficient nutrition to meet the needs of leaf expansion, flowering and fruit setting of fruit trees, and the fertilizer applied can not only promote fruit trees to fully absorb nutrients, but also save nutrients very well. when the spring begins in the second year, it is also a key measure to establish the quality and yield of fruit trees in the second year.
