Cultivation and management techniques of flower pomegranate

1) Soil management: Leave a 1-meter diameter tree tray under the tree. In areas where the soil temperature is too high in summer or in courtyards where cement is hardened, tree trays can be used to cover organic matter (straw, chaff, sawdust, etc.), or tree trays can be used to grow grass (lawn planting) to achieve cooling and moisture retention and promote normal growth and development. For those without mulch or grass, intertill and weed the tree tray 3-4 times a year at a depth of 5-10 cm.

2) Fertilization: 5-7 months after the seedlings survive in the planting year, a small amount of fertilizer is applied to the tree tray every month, and 1-2 kg of decomposed manure water is applied to each plant and a small amount of urea is added. Before autumn leaves fall, dig circular ditch and apply organic fertilizer 20-30 kg per plant. From the second year to the full fruiting period, base fertilizer is applied once a year in circular furrow, compound fertilizer and decomposed manure are applied or scattered 3-4 times in tree tray, and the fertilizer amount is adjusted according to the yield. At the same time, attention should be paid to foliar topdressing in growing season, nitrogen fertilizer is mainly used in early stage, phosphorus and potassium fertilizer are mainly used in middle and late stage, and the total concentration of fertilizer solution should not exceed 0.3%. Biogas or decomposed manure can also be sprayed as topdressing outside roots.

3) Irrigation and drainage: The key period of pomegranate irrigation is mainly the germination stage, fruit expansion stage and the three stages before defoliation. The soil moisture is kept at 60-80%. The other stages are mainly controlled according to the soil moisture. Pomegranates drought resistance is not waterlogging, in the growing season to pay attention to drainage, to prevent soil and tree tray too long ponding, causing waterlogging damage.

1, pomegranate shaping

Pomegranates like light, garden pomegranate shaping that is to consider the growth and fruiting characteristics of pomegranate, to have a certain ornamental, commonly used tree shape is mostly without trunk cluster or no central trunk tree, mainly "v" shape, natural happy shape and so on.

1)"V" shape: divided into two types of trunk and no trunk, from the ground (no trunk) or trunk on the selection of two main branches symmetrically extended to both sides, the main branch and the ground angle of 45-55°. Each main branch is equipped with 2-3 lateral branches, the first lateral branch is about 60- 70cm away from the base of the main branch, the second lateral branch is opposite to the second lateral branch, the third lateral branch is on the same side as the second lateral branch, and the lateral branch spacing is 50- 60cm. The fruiting branch groups are reasonably arranged on the main and lateral branches. The key to shaping is to make the main branches extend smoothly. That is, after planting the first 2-3 years of winter shear, the main branch should be taken to cut short, promote the cutting of the ribbon □ bud out of strong branches as extended branches. Flower pomegranate cultivation management techniques a, soil management: leave a diameter of 1 meter under the tree tree. In areas where the soil temperature is too high in summer or in courtyards where cement is hardened, tree trays can be used to cover organic matter (straw, chaff, sawdust, etc.), or tree trays can be used to grow grass (lawn planting) to achieve cooling and moisture retention and promote normal growth and development. If not covered or grassed, the tree tray is weeded 3-4 times a year at a depth of 5-10 cm. 2. Fertilization: after the seedlings survive in the planting year, a small amount of fertilizer is applied to the tree tray every month from 5 to 7 months, and 1-2 kg of decomposed manure water is applied to each plant plus a small amount of urea. Before autumn leaves fall, dig circular ditch and apply organic fertilizer 20-30 kg per plant. From the second year to the full fruiting period, base fertilizer is applied once a year by circular furrow, compound fertilizer and decomposed manure are applied or scattered 3-4 times in tree tray, and the fertilizer amount is adjusted according to the yield. At the same time, attention should be paid to foliar topdressing in growing season, nitrogen fertilizer is mainly used in early stage, phosphorus and potassium fertilizer are mainly used in middle and late stage, and the total concentration of fertilizer solution should not exceed 0.3%. Biogas or decomposed manure can also be sprayed as topdressing outside roots. Third, irrigation and drainage: the key period of pomegranate irrigation is mainly the germination period, fruit expansion period and the three periods before defoliation, soil moisture is maintained at 60-80%, and other periods are mainly controlled according to soil moisture. Pomegranates drought resistance is not waterlogging, in the growing season to pay attention to drainage, to prevent soil and tree tray too long ponding, causing waterlogging damage. Fourth, pomegranate shaping pomegranate tree likes light, garden pomegranate shaping should consider the growth and fruiting characteristics of pomegranate, but also have certain ornamental, commonly used tree shape is mostly tree shape without trunk cluster or central stem, mainly "V" shape, natural open shape, etc. 1,"V" shape: divided into two types of trunk and no trunk, from the ground (no trunk) or trunk on the selection of two main branches symmetrically extended to both sides, the main branch and the ground angle of 45-55°. Each main branch is equipped with 2-3 lateral branches respectively, the first lateral branch is about 60- 70cm away from the base of the main branch, the second lateral branch is opposite to the first lateral branch, the three lateral branches are on the same side as the first lateral branch, and the lateral branch spacing is 50- 60cm. The fruiting branch groups are reasonably arranged on the main and lateral branches. The key to shaping is to make the main branches extend smoothly. That is, after planting the first 2-3 years of winter shear, the main branch should be taken heavy short, promote the opening bud to grow strong branches as extended branches. 2. Natural happy form: The tree has trunk tree shape with trunk height of 60- 100cm, 3-4 branches with reasonable orientation are selected and reserved on the trunk as main branches, the horizontal projection angle of the main branches is 90-120 degrees, the angle between the main branches and the trunk is 45-60 degrees, the first lateral branch is selected and reserved at the position 50- 60cm away from the trunk on the main branch, the second lateral branch is selected and reserved at the opposite side of the first main branch, 6-8 lateral branches are selected and reserved, and fruiting branch groups are arranged on the main branch and the lateral branch. V. The principle of pruning and pomegranate pruning is: visible is not dead, invisible is not chaotic, so that the upper part is sparse and the lower part is dense, the outer part is sparse and the inner part is dense, and the large branches are sparse and dense, so as to ensure sufficient light in the crown bore. Winter pruning mainly focuses on thinning and long putting, mainly thinning overlapping branches, dense branches, pest branches, flourishing long branches and excessive long branches, so as not to disturb the tree shape. During the growing season, excess sprouts are removed to reduce nutrient consumption by excess branches and leaves. The first 3-4 years after planting are mainly plastic, and from the third year, some auxiliary branches are ringed to promote their flowering and fruiting. While promoting flowering and fruiting, the cultivation of main branches at all levels and the allocation of fruiting branch groups should be continuously improved. The mixed buds (flower buds) of pomegranate are born at the top or near the top of the middle branch. Therefore, for these short branches, the bearing mother branch should be kept long and short pruning is prohibited to utilize the fruit. For strong branches and long branches with space available, girdling, ring cutting or pulling branches should be carried out to ease the growth and promote flowering and fruiting; those without space or affecting the growth of backbone branches should be resolutely thinned. In full fruiting period, it is necessary to timely retract or replace the fruiting branch group, appropriately retract the drooping branches, reasonably utilize the strong branches, thin the weak branches, dense the branches, maintain the good tree structure, and postpone senescence. VI. Disease and pest control: Pomegranates in the courtyard generally have light diseases and pests. Prevention and artificial control are the main methods for pest control. After defoliation, the dead branches, diseased branches and defoliation shall be cleaned and removed in time, and burned intensively. Spraying 5°Be sulfur mixture before germination to kill overwintering pests. During the growing season, the branches, leaves and fruits of pests and diseases are often removed manually, and the disease spots are scraped off; pests and egg pieces are captured manually. Chemical control by spraying insecticides and fungicides when necessary. When spraying pesticides, biological and mineral pesticides that are nontoxic to humans and livestock or chemical pesticides with low toxicity and low residue should be selected. What are the cultivation and management techniques of pomegranate flowers, and the corresponding precautions

What cultivation and management techniques and maintenance methods do flower pomegranate have? This has always been a concern of flower friends. Today, Xiaobian has compiled specific methods for flower pomegranate cultivation and management for everyone, hoping to provide help for everyone.

soil

Set aside a 1-meter diameter tree tray under the tree. In summer, the soil temperature is too high to realize cooling and moisturizing, and promote normal growth and development. If not covered or grassed, the tree tray is weeded 3-4 times a year at a depth of 5-10 cm.

fertilization

After the seedlings survive in the planting year, a small amount of fertilizer is applied to the tree tray every month from May to July, and 1-2 kg of decomposed manure water and a small amount of urea are applied to each plant. Before autumn leaves fall, dig circular ditch and apply organic fertilizer 20-30 kg per plant. From the second year to the full fruiting period, base fertilizer is applied once a year by circular furrow, compound fertilizer and decomposed manure are applied or scattered 3-4 times in tree tray, and the fertilizer amount is adjusted according to the yield.

irrigation and drainage

The key stages of pomegranate irrigation are germination stage, fruit expansion stage and pre-defoliation stage. It is suitable to keep soil moisture at 60-80%, and other stages are controlled flexibly according to soil moisture. Pomegranates drought resistance is not waterlogging, in the growing season to pay attention to drainage, to prevent soil and tree tray too long ponding, causing waterlogging damage.

training and pruning

Pomegranates like light, garden pomegranate shaping should consider the growth and fruiting characteristics of pomegranate, but also have certain ornamental, commonly used tree shape is mostly without trunk cluster or central stem tree shape, mainly "V" shape, natural open shape and so on.
