In addition to pests and diseases
1. Clear Garden. Cut off the dead branches of the pests, clear the dead fruits on the trees, under the trees, dried and dried branches, fallen leaves, rotten fruit, weeds, etc., and carry the park outside to concentrate or burn. 2. Scratch old skin, white trunk. When scraping the skin, the old tree can be scraped harder, the small tree scraped lighter, and immediately after the scraping, it was painted white. Whitening agent for water 40 parts + lime 10 parts + salt 0.5 ~ 1.0 parts + Lithosulfide solution 2 parts or the original residue 5 parts + clay or semolina 2 parts, the amount of coating is not suitable for downstream. 3. Turn the tree. In the winter, the pomegranate pests in the soil include peach borer, pomegranate Zingiella and so on. Should be combined with the winter pomegranate garden fertilization and irrigating frozen water, before the soil is frozen, the soil under the tree is turned over again, about 20 cm deep, so that the wintering pests in the soil are frozen or eaten by birds.
Fertilizer
The application of organic fertilizer can make the nutrient reserves of the tree better, and it is a prerequisite for guaranteeing early high yield and high quality. The specific method of fertilization is to dig a ring groove with a width of 40 cm and a depth of 40-50 cm around the crown of the pomegranate tree, or centered on the main trunk of the fruit tree. On the outer edge of the fruit tree, surround the fruit trees, dig 30 cm deep, and make the width 20 Centimeter fertilization points, and digging the ditch on the same day, fertilization the same day, depending on the tree vigor, tree age, fertility and production of the year. General plant strains of good quality farmyard fertilizer 30 ~ 60 kg, phosphate fertilizer 2 ~ 4 kg, the topsoil and manure mixed into the ditch, covered with new soil in the ditch. Do not damage the roots of large trees when the roots are topdressing and digging trenches. The roots of young trees are shallow and the distribution surface is small.
Winter pruning
Winter pruning generally uses measures such as thinning, short cutting, long releasing, and retraction. Branching: Removes all branches from the base. Mainly used for strong twigs, especially on the back of leggy branches and debilitating drooping branches, branches and branches of diseases and insects, cross-branches, and branches and stems, dense branches outside, in order to improve ventilation and light transmission, promote flowering results, improve The role of fruit quality. Short cuts: Cut off some of the branches. Mainly used for old tree renewal and sapling shaping. In order to ensure that the pomegranate flower, generally in the mature tree on the short cut, otherwise prone to the emergence of new shoots, affect the flowering results. Long release: no trim on the branches. It is mainly used for saplings and mature trees, which can promote the formation of short shoots and flower bud differentiation, and has the effect of prompting the early results of young trees and the easing of Wangshu, Wangzhi and nutrient growth. Retraction: The perennial branches are truncated to the branches. It is mainly used to update the tree potential of rejuvenation, and to update the result branches and branches so that the structure of the tree is compact, avoiding the outward movement of the result parts and the result that the branches are drooped and the fruits are in contact with the ground. Retraction has a significant effect in promoting growth.
Frost protection
1. Buried. Before the winter soil is frozen, the branches are overwhelmed by the buried soil of about 30 to 50 cm, and the branches are released from the soil in early March of the following year. This can effectively prevent freezing damage. 2. White, wrapped grass. Large trees can adopt the methods of white-painted trees or tree trunks to reduce the occurrence of frost damage. 3. Vaseline, spray lime solution. After the plants are defoliated, Vaseline is applied to shoot shoots to significantly enhance their ability to resist cold. 4. Winter irrigation. After deep-foliation of fruit trees and top-dressing of roots, timely winter irrigation should be conducted. When winter irrigation time is used for night-time freezing, daily average temperature is stable at about 2°C. Http://Content/f966854b-46ff-4f1b-aef7-3d7b18f1d068?cType=2
