Citrus root cutting methods and precautions

Citrus root system has strong self-thinning and regeneration ability. After aging or adverse environment, it can die by itself and be replaced by new roots. Therefore, root cutting and root promotion treatment by stages can promote root expansion, make it penetrate deeper, and improve yield and quality. So how can citrus roots be broken in winter? Let's take a look at it together with Xiaobian.

I. Root cutting time

Generally, young citrus trees are rooted twice a year, once in June and once in August. For hanging fruit trees, roots can be cut once a year, in June or August is OK. Therefore, it is obviously impossible for citrus roots to be cut off in winter. The winter temperature is low and the plants enter dormancy period. At this time, the root activity is low. If the roots are cut off at this time, the roots can not recover in time, but also have weak resistance to low temperature, which is easy to cause plant death.

II. Root cutting method

1. Young trees are rooted

Young tree first root is, to dig a ditch on both sides of the crown, the length of the ditch in 70 cm, depth in 40 cm, width is not limited, generally able to cut off the root knot. After cutting roots, fertilize in the ditch, 50 catties of green manure, 0.2 catties of urea, 0.5 catties of calcium superphosphate and 5 catties of human excrement and urine water on each tree. It is best to fill the ditch with soil. In the second time when the root and the first time is the cause, that is, in the canopy on opposite sides can be.

2. Hanging fruit trees and breaking roots

To dig trenches on both sides of the canopy, the length of the trench is about 3 meters, the depth of the trench is about 70 cm, and the width is also cut off at the root. After cutting roots, fertilizer should also be applied, but the amount of fertilizer should be larger than that of young trees at this time. Green manure 50 jin, urea 0.7 jin, calcium superphosphate 2 jin, human excrement and urine 80 jin can be filled with soil.

Third, pay attention to details

In case of drought season, need watering after root cutting, especially for young tree root cutting is also focused, such as to prosperous or to the fruiting age but no fruit trees, to focus on root cutting. For hanging fruit trees, the wound needs to be trimmed after the root is cut off to make it smooth. If the wound is relatively large, some liquid medicine, such as carbendazim, needs to be applied to the wound to prevent root rot. Young trees are rooted twice a year, once in June and once in August; hanging fruit trees, though also rooted at this time, are selected only once a year, that is, between June and August.
