Cultivation method of pomegranate flower
plant
After defoliation in autumn and before germination in the following spring, you can plant or change pots. The ground should be planted in sunny, leeward and slightly higher places, with loose, fertile soil and good drainage. Potted plants are made of humus soil, mixed culture soil of soil and river sand, and appropriate amount of decomposed organic fertilizer is added. When planting, soil should be brought, the overground part should be cut short properly, watered after planting, kept cool, and moved to a ventilated and sunny place after germination and survival.
Light and temperature
Light and temperature are important conditions that affect the formation of flower buds. Adequate sunshine is needed in the growing period. The more sunshine, the brighter the flowers will be. Leeward, sunny and dry environment is conducive to the formation and flowering of flower buds. When the light is insufficient, only the long leaves will not bloom, which will affect the ornamental effect. The suitable growth temperature is 15 -20℃, and the winter temperature should be lower than-18℃, otherwise it will be frozen.
Water fertilization
Pomegranate is drought-tolerant and likes dry environment. Watering should master the principle of "dry and thorough", so that the basin soil is "dry and wet, dry and not wet". In the flowering and fruiting period, you should not water too much and the soil in the basin should not be too wet, otherwise the branches will grow white, leading to the phenomenon of falling flowers, falling fruits and cracking fruits. Drainage should be done in time in rainy season. Both ground-planted pomegranate and potted pomegranate should be fully applied with base fertilizer, and then 1 times decomposed organic fertilizer should be applied before winter, and 1 times decomposed organic fertilizer should be applied before winter every year. Young trees should be planted in circular ditches 1 m away from trees, and old trees should be planted in radial ditches with a depth of 20 cm. Potted pomegranate should be applied with thin fertilizer frequently, and thin fertilizer and water should be applied 1 time every week during the vigorous growth period. Long-term topdressing of phosphorus and potassium fertilizer can protect flowers and fruits.
Plastic trimming
Because pomegranate branches are thin and messy, they need pruning to achieve the effect of beautiful plant shape. Generally, pomegranate can be made into round head or flat head; It can also be made into a cluster opening shape; You can also be pomegranate bonsai. Cut off dead branches, long branches, cross branches, weak branches and dense edges by thinning and short cutting. Grasp the heart in time in summer, sparse flowers and fruits, and achieve the effects of ventilation and light transmission, beautiful plant shape and flowers and fruits.
Morphological characteristics of pomegranate flowers
shape
Pomegranate flower is the flower of deciduous shrub or small tree pomegranate. The plant height of pomegranate is 2 ~ 5m, and the highest is 7m. The trunk is grayish brown, pomegranate flowers fall off in pieces, and the tender branches are yellow-green and smooth, often quadrangular, with prickly branches and no terminal buds.
leaf
Pomegranate flowers have opposite or clustered leaves, oblong or obovate, ranging in length from 2 to 8 cm, entire, smooth leaves, short stalks, and new leaves are light green or bronze.
flower
Pomegranate has several peanuts at the top of branches or leaf axils. The flowers are bell-shaped, fleshy, 6-lobed at the top, smooth and waxy on the surface, orange-red, persistent. Petals 5 ~ 7 are red or white, single or double.
Pomegranate flower is a unisexual flower. Flowers on trees can be divided into female flowers and male flowers. Two flowers are very beautiful. The base of male flower is small, and the edge is obtuse triangle, which will fall off after flowering; The base of the female flower has obvious swelling, which can be seen when flowering, and only the female flower will bear fruit.
The flowering period of pomegranate is from June to July.
fruit
The berries of pomegranate flowers are spherical and yellow-red. Most seeds have fleshy exocarp, and the fruit ripens in September ~ 10. Pomegranate cultivars are divided into two categories: fruit pomegranate and flower pomegranate.
Pomegranate fruit ripens in September-65438+10.
Ecological habits of pomegranate flowers
Pomegranate flowers like sunny and dry environment, which is cold-resistant, drought-resistant, waterlogging-resistant, and shade-resistant, and the requirements for soil are not strict, and the fertile, loose and nutritious sandy loam is the best.
Propagation mode of pomegranate flowers
Pomegranate flowers are often propagated by cutting, dividing plants and layering.
cutting
Two-year-old branches can be selected in spring or semi-lignified branches can be selected in summer, and they can take root after 15 ~ 20 days. In early spring and April, when the buds germinate, we can dig out strong roots and plant them separately.
Stratified propagation
It can be done in both spring and autumn, and carving is not necessary. Before germination, the buds are pressed into the soil with tillers. After taking root in summer, they are cut off from the mother plant and become seedlings in autumn.
Open field cultivation should choose a place with sufficient light and good drainage. In the process of growth, it is necessary to remove roots and seedlings, and cut off dead branches, diseased branches, dense branches and long branches to facilitate ventilation and light transmission.
Pot propagation
Plant shallowly and control watering. It should be dry and not wet. During the growth period, the seeds should be removed, the growth of vegetative branches should be controlled, and the formation of flower buds should be promoted. Propagation mode of pomegranate flowers
