Editor's note: The current time should seize the opportunity to prune fruit trees in winter. When pruning, it should be combined with organic fertilizer. According to the condition of the tree, the number of flower buds, the site conditions, and the fertility of the soil, it is determined whether the pruning method or the pruning method should be used. After trimming, it is necessary to protect the cutting edge with a protective agent, such as oil, seal and shear. This article starts with the problems encountered in the winter shearing process and sorts out several pruning measures for readers for reference.

The three problems of fruit tree winter cut

Leaving behind many slugs, many fruit growers inadvertently leave slanting when pruning fruit trees, which makes the fistula difficult to heal. Not only is it easy to run water, rain, and rot bacteria, but nutrients cannot be circulated, eventually causing the cornices to harden and die. The correct way is: for small obliques, just turn the scissors up and cut it again. For a large skewer, use a knife to flatten the skin, and make the skin longer than wood. Hold the skin slightly short and hold the xylem tightly. Leave a long point and seal with a medicament to ensure complete healing.

Strictly sealed cutting kerfs oscillate and pull back and forth, the surrounding phloem has been damaged or cracked, rain easily inflow, easy to invade the bacteria. The correct method is: seal the top and then seal the surrounding, the edge of the drug cracks wet medication, so that healing is also fast. Found that the size saw cracks have to be sealed. Always look at the nicked seal until it heals.

After the diseased crickets were protected and the scraped sick belts were burned and buried, the fruit growers often only applied the medicines to the treated sicknesses. The small sicknesses were cured, and the large ones turned black and rotted. The correct method is: After disinfection and sterilization with the drug, and then use the cure to seal the disease, the standard is not exposed xylem. Do not wrap it with plastic paper for a long time, as it will cause moldy rot in the xylem.

Fruit tree winter cut to stare at "four points"

Tree species before cutting deciduous Walnuts, grapes and other vulnerable fruit trees, after the first cut apricot, plum, peach and other stone fruits, after cutting apples, pears and other fruit trees.

The tree vigor should be cut first in the same species, then in the meantime tree and then in the tree.

The amount of flowers in the "Year of the New Year" tree was cut early, and some of the weak branches and weak shoots were evacuated, so that the limited storage nutrients of the tree were concentrated to supply the remaining shoots, laying a good foundation for the next year's results. The "small year" tree night cut can identify the flower buds, so that the winter shear flower buds, to ensure that there is a certain amount of production.

Areas with the same variety, high altitude winter cold fruit area above 800 meters should be properly cut, 700 meters below the low altitude warm fruit area should be properly cut. Severely cold winter fruit areas can be trimmed one month before sprouting, and miss the low-temperature and cold period through appropriate late cuts, avoiding frozen stem cuts and reducing the incidence of rot.
