The management of dormancy period in persimmon trees

With the improvement of people's ecological awareness, more and more people began to use persimmon trees as garden greening species. In winter, the persimmon tree enters a dormant period. The author combines the characteristics of the dormancy period of persimmon trees in the garden and introduces the management of the dormancy period of persimmon trees.

First, increase base fertilizer. In order to promote the restoration of tree vigor and accumulation of nutrients, organic fertilizer can be applied in combination with ploughing before the soil is frozen. Basal fertilizer is mainly farmyard fertilizer. Phosphate fertilizer and potash fertilizer are best mixed with farmyard fertilizers. According to the size of the tree and the number of fertilizers per plant 25 to 50 kg per plant fertilizer, mixed with superphosphate 1 to 2 kg and potassium sulfate 0.2 to 0.5 kg, applied to the fertilization ditch and the soil mixed evenly, and then cover the soil.

Second, pruning. Limps, weak twigs, and diseased worms are ineffective and should be cut off as soon as possible. The growth branches are small, long, dense, and cross-cutting. The moderate growth leaves a short 2/3 cut and promotes new shoots. As a result, after flowering, due to lack of nutrients, flower buds could not be formed in the year and they should be cut off from the base. However, a strong, well-developed 2-3 foot short-cut can be made to promote long branching. Falling and falling fruit can generally be a good result of the mother.

Third, clean up and deep turn. In conjunction with the winter shears, the pests, litter, and weeds on the ground are carefully removed, and all garbage is taken out of the hospital and burned. After cleaning up, we must pay close attention to winter turning. Winter turning can not only improve the soil structure and increase soil fertility, but also can turn over the wintering pests in the soil to freeze or die on the surface, so that it can't be harmed in the following year.

Fourth, pest control. 1. Scrape the bark. Bark seams are a good place for wintering of pests. Scrapping bark can greatly reduce the base number of overwintering pests. Therefore, it is necessary to scrape the rough outer skin of persimmon trees. 2. The trunk is painted white. After persimmon tree scraping, it is necessary to apply the whitening agent to the scraping site. The concentration of the coating solution should be moderate, so that the application is not lost, and it should not fall off after drying and it should not fall off. 3. Apply mud. The overwintering bases of the pests such as kaki and other pests in the trunks of grafted rootstocks are very large. Because the bark of the black date is difficult to scrape, the tree trunks can be painted with a muddy, thicker mud, and the mature larvae are suffocated in the trees. in. 4. Spray control. When the persimmon tree is dormant, after the winter shearing work is completed, 3 to 5 Baumel's lime sulfur or 5% diesel emulsion should be uniformly sprayed under the tree and under the tree to kill the insects that remain on the tree and under the tree. source.

Fifth, the tree is cold. Because persimmon trees have poor cold resistance, the following measures can be taken to prevent cold in the trees under the conditions permitting: First, the frozen water should be poured in time; second, the trunk should be tied with cold-proof materials (such as grass rope, rice straw, waste cotton, etc.); Third, it is strictly forbidden to snow under the trees to prevent accumulation of water and accumulation of ice, which will lead to tree death.
