(2) water. Pomegranate is drought-tolerant. When it grows vigorously in summer, it should be watered frequently (watering less during flowering and fruit-setting period is easy to drop flowers and fruits), and the soil should be kept moist, not too wet. Pomegranate is afraid of waterlogging, so put down or move into shelter in rainy days to prevent water from accumulating in the basin. Water less in winter dormancy period, as long as the basin soil is wet.
(3) fertilization. Pomegranate likes fertilizer. When planting, in addition to proper application of base fertilizer, decomposed liquid fertilizer should be applied every half month during the leaf opening period, bud pregnancy period and fruit growth period after flowering. After budding, apply 0.2% potassium dihydrogen phosphate or liquid fertilizer made of poultry manure twice (about a week apart), so that the flowers can be bright and fruity. But don't fertilize during flowering.
(4) plastic surgery. Pomegranate has strong germination ability and can produce new branches several times a year. Generally speaking, robust new branches born in spring can form fruiting mother branches. In the following spring, the short shoots from terminal buds or axillary buds often bloom, and the flowers with terminal buds are the most fruitful. The steep long branches born in the same year or the new branches grown from old perennial branches generally do not bloom in the same year, so we should pay attention to this feature when shaping. Branches born in summer and autumn are difficult to form fruiting branches and should be cut off in time. Plastic surgery in pomegranate bonsai is often performed before germination in spring. Steep long branches, erect branches, over-dense branches and twigs should be cut off, but attention should be paid to keeping those thick fruiting branches. From the branches pruned in spring, you can find some people with a certain attitude to prune and cut them, and you can go to a small pot to watch them in the third year after you survive. If the mother branch is too long to affect the shape, you can cut off the branch length of about 1/3, but you can't cut off all the branches born last year, otherwise it will be difficult for this pomegranate to blossom and bear fruit that year.
(5) pest control. Pomegranate has aphids, scale insects, inchworms, borers and other pests, which should be prevented in time.
Whole method of potted pomegranate tree
1. Pot soil preparation in pomegranate bonsai: The root system of potted pomegranate only moves in a small range in the pot, so it is required that the pot soil is rich in nutrition and has good water retention, drainage and ventilation performance. The preparation method is as follows: using 5 parts of urban road sweeping soil, 3 parts of fermented chicken and duck bird droppings, 2 parts of vermiculite or slag, adding a little plant ash, then mixing with meat washing, fish and shrimp water, drying in the sun and sieving to obtain the device.
Second, the production and modeling of pomegranate bonsai: pomegranate bonsai varieties in Zaozhuang generally include Dahongpao, Sanbai pomegranate and frozen pomegranate with rock sugar. In terms of material selection, it belongs to the category of stump bonsai, mostly wild stumps that have been transplanted for many years, and can also be cultivated with seedlings, mostly oblique or horizontal plants. Inclined trunk type: the asbestos trunk leans to one side, the branches and leaves are naturally and orderly distributed, and the tree type is dynamic and poetic. Lying dry type: the main part of pomegranate trunk lies on the basin surface, which looks like lightning and the wind falls down. The shape of the tree is old and strange, which is very interesting.
Third, the plastic maintenance in pomegranate bonsai: the plastic pruning in pomegranate bonsai should first consider the shape, and then consider the fruit setting rate of asbestos. For spring shoots and autumn shoots, the required shape can be fixed by twisting, and the dense part of new lateral branches can be cut off from the base. Long branches can be shaped by multiple coring, and full lateral buds can be formed between leaf axils as soon as possible, so as to make a good nutritional reserve for new bearing mother branches in the coming year. Dense needle-like short branches can be cut off. Pomegranate bonsai's conservation management is different from ordinary tree bonsai. For example, it is not advisable to water more during flowering and fruit maturity, and try to control water, otherwise the flowering period will be short and the fruit will crack, which will affect the ornamental effect.
Water: Generally, water at 9: 00 am or 3: 00 pm in spring and autumn. In hot summer and early autumn without rain, water it at least twice a day. Winter 3? Water once every five days (the number of days and times depends on the wetting degree of the basin soil), which is beneficial to the safe overwintering of bonsai pomegranate.
Fertilization: Generally speaking, basal fertilizer is applied once a year in winter or early spring, and fertilizer is applied once before germination, and foliar fertilizer is sprayed for 2? Three times, it is best to apply base fertilizer with decomposed organic fertilizer, which is beneficial to root absorption and promotes the rapid growth of pomegranate. Pest control: Pests and diseases are the enemy of bonsai pomegranate, which can be viewed lightly and killed seriously. Pomegranate diseases mainly include root rot and dry rot. Pests include scale insects, peach moth, etc. Pests can be eliminated by artificial catching and whole pruning. In addition, fertilizer and water management should be strengthened to enhance pomegranate's ability to resist pests and diseases.
In addition, it is generally more appropriate to change pots for potted pomegranate before pomegranate trees germinate. 20% of the culture soil must be placed under the pot soil and applied with sufficient base fertilizer. After changing the pot, it should be watered to make pomegranate grow normally.
Planting method of potted pomegranate
Pomegranate flower, also known as rose pomegranate, is native to Iran and Afghanistan in Central Asia. I like sunny and dry environment, which is cold-resistant, drought-resistant, waterlogging-resistant, and shade-resistant. I don't have strict requirements on soil, and fertile and loose sandy loam is the best.
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 (visible when flowering), and only the second flower will bear fruit.
The propagation of potted pomegranate generally adopts sowing method and cutting method. Sowing method: Choose fully mature fruits, take out the seeds, wash them in the shade, store them in the sand, and sow them in the seedbed around Grain Rain in the following spring. The soil with a thickness of 1 cm can germinate in about 20 days, and can be transplanted when there are 4 real leaves.
Cutting method, the propagation rate of young stem cuttings in summer is high, or branches over 2 years old can be cut into branches with the length of 15cm ~ 30cm before bud germination or during winter dormancy, and callus will be generated after being buried for one month, which can be cut in spring and take root and germinate after one week.
Pomegranate is suitable for growing in sunny and well-ventilated places. Potted pomegranate should be placed in a sunny place, preferably in a sunny place all day. Insufficient sunshine can easily lead to virtual growth, less flowering and less fruit. Pomegranate should be properly watered. If the soil is too dry, it is easy to drop buds, dried fruits and fruits. If the soil is too wet, it is easy to cause the phenomenon of falling buds and cracking fruits.
Fertilize potted pomegranate, apply basic fertilizer once in autumn and winter, all kinds of fermented bean cakes, peanut bran, soybean water and fishy water can be used, apply quick-acting compound fertilizer once before germination and flowering in spring, and apply phosphate fertilizer every 15 to 30 days during flowering, which can meet the normal growth needs of potted pomegranate and ensure bright flowers and fruits.
Potted pomegranate is generally pruned after defoliation in winter to remove its roots and tillers, prune drooping branches, dead branches and transverse branches inside the crown, and remove over-dense branches, diseased branches and aging branches to make the crown grow evenly.
