The latest root-cutting methods and matters needing attention of citrus

Citrus roots have a strong ability of self-thinning and regeneration, and they can die and be replaced by new roots after senescence or adverse environment, so cutting roots and promoting roots by stages can promote the expansion of roots and make them go deeper. It can also improve yield and quality. So whether the citrus can be cut off in winter and how to do it? Come and have a look with the editor.

1. Root-cutting time

In general, young citrus trees cut off their roots twice a year, once in June and the other in August. For hanging fruit trees, the roots can be cut off once a year, either in June or August. Therefore, it is obviously impossible for citrus to cut off roots in winter. When the winter temperature is low and the plant enters a dormant period, the root activity is low. If the root is cut off at this time, the root system not only can not recover in time, but also has weak resistance to low temperature. It is extremely easy to cause plant death.

Second, the method of root cutting

1. Young trees cut off their roots

Young trees cut off their roots for the first time, to dig a ditch on both sides of the crown, the length of the groove is about 70 cm, the depth is about 40 cm, the width is not limited, generally can cut off the root knot. After cutting the root, fertilize in the ditch, each tree green manure 50 jin, urea 0.2 jin, calcium superphosphate 0.5 jin, human feces and urine 5 jin, it is best to fill the ditch. The reason for the second root loss and the first time is that it can be carried out on the opposite sides of the crown.

2. The root of the fruit tree is broken.

To dig trenches on both sides of the crown, the length of the ditch is about 3 meters, the depth of the ditch is about 70 cm, and the width is also to cut off the root. Fertilizer should also be applied after root cutting, but the amount of fertilizer applied at this time is larger than that of young trees, with 50 jin of green manure, 0.7 jin of urea, 2 jin of superphosphate and 80 jin of human feces and urine, and then fill it with soil.

Third, pay attention to details

In the dry season, it needs to be watered after root cutting, especially for young trees, such as trees that grow vigorously or reach fruiting age but do not bear fruit. For hanging fruit trees, the wound needs to be trimmed to make it smoother after the root is cut off, and if the wound is large, then some liquid medicine, such as carbendazim, needs to be applied to the wound to prevent root rot. Young trees cut off their roots twice a year, once in June and once in August, while hanging fruit trees cut off their roots during this period, but only once a year, that is, a choice is made between June and August.
