Anti-freeze management measures for fruit trees

(1) Management measures after freezing damage of evergreen fruit trees such as citrus, navel orange and bayberry.

1. After the frozen crown care

After the fruit trees are frozen, the aerial parts suffer different degrees of damage or die. While the citrus is damaged before the repair, all the leaves are removed, and other evergreen fruit trees such as bayberry should be trimmed in time to restore the crown as soon as possible and reduce losses.

2. Loose soil warming, irrigation and yang

Immediately after thawing, loosen the soil under the canopy to increase the soil temperature. Especially after dry freezing, the roots and the tree body need more water, so it is necessary to fill the water in time.

3. Sawing the affected branches, coated wound protectants

After pruning or sawing, it is necessary to master the "timely", that is, when the new shoots sprout, the raw and dead fruit lines are clearly cut off, or the saws are dried. In principle, the dead part is cut off, and all the living branches are kept. In this way, it is beneficial to the accumulation of nutrients in the tree and the promotion of early sprouting of new shoots. When trimming or sawing, larger wounds should be coated with a protective agent to reduce moisture transpiration and protect against pests and diseases. In principle, the new shoots that have been taken after freezing should be preserved. However, a bud with 2 to 3 new shoots should be removed to ensure normal growth of the new shoots and avoid canopy closure. New shoots that have grown too much should be topped in time. After the snow damage occurs, the fruit trees are coated with a protective agent (stone sulphur, paint, etc.) to prevent decay. For the branches that have been cracked and not broken, it should not be easily sawn off. It should be propped up with ropes or pillars to restore the original shape, and then waxed oil, fresh cow dung, yellow mud slurry, etc., to promote healing and restore growth. For unaffected foliage, trimmed as much as possible, the branches that have been torn and tied, and trimmed according to the severity of the injury to reduce nutrient and water consumption. New shoots that are taken under the broken branch should be properly retained in order to update and rejuvenate. In addition, it is also possible to exchange high-breaking saplings or mature trees. Old trees that cannot be updated should be replanted.

4. Rational fertilization, restore the tree

After freezing, the function of the tree body is significantly weakened. In the spring, fertilization should be carried out with water and fertilizer, and the quick-acting nitrogen fertilizer should be used as the main factor. The thin application should be applied thinly and thin, and the fertilization should not be too concentrated. For the first time, nitrogen fertilizer is the main one, and the second and third times are appropriate to increase phosphorus and potassium fertilizer. In addition, foliar topdressing and supplementation of trace elements should also be carried out in due course.

5. Pay attention to the flower

The frozen tree has abnormal flower and obsolete flowers. Especially the light-calored tree has a large amount of flowers and low fruit setting rate. In order to reduce the nutrient consumption when the tree is flowering, it is generally necessary to remove the deformed flower and obsolete flower from the light frozen tree to improve the seat. Fruit rate. The frozen tree does not leave flowers, prompting it to restore the tree as soon as possible.

6. Prevention of pests and diseases

After freezing, some branches are dead or damaged, and the branches are bare. In the hot season in summer, it is easy to cause sunburn and cracked skin. It is most prone to resin disease. Generally, in the early summer and late autumn, the skin is scraped first, and then the alkali is used at a concentration of 1:4. Water, painted 2-3 times, can achieve better results, can also be used to brush the branches with stone sulfur to prevent sunburn. In addition, special attention should be paid to the prevention and control of aphids, wind butterflies, leaf curlers, mites, leaf miner and other pests and diseases, and promote the normal growth of new shoots and young leaves.

(2) Management measures after freezing damage of deciduous fruit trees such as pear, peach, apple and kiwi.

1. Scissor-stricken branches and coated wound protectants: After the wintering branches of young trees are damaged by freezing, they can be observed about half a month after germination (the tree is usually germinated for half a month to one month) and the stems are cut off. In part, grafting in the spring (peach tree grafting in summer), the grafting method is commonly used in the splicing method and the cutting method. Apply 3-5 waves of sulphur sulphur mixture to the kerf and cut.

2. Reasonable thinning and fruit thinning, control the amount of results, as soon as possible to restore the growth of the tree, and promote partial healing of the damage.

3. Strengthen the management of fertilizer and water: After the fruit trees are subjected to freezing, they should be topdressed and watered as soon as possible to promote their growth.

4. Prevention and control of pests and diseases and timely planting new trees.
