Huanghua Peony Pomegranate and Cultivation Management Technology

Peony Pomegranate is a pomegranate variety that has been excavated and developed in recent years. It has a large flower and a long flowering period. It is both ornamental and edible, and is deeply loved by the general public. In order to enrich this precious tree species, the technical personnel of the Mengyin County Science and Technology Department made full use of local resources. After years of research and development and selective breeding, after the cultivation of red peony and pomegranate, the yellow flower peony was successfully selected. pomegranate. This type of pomegranate flower is similar to safflower hibiscus pomegranate. It has a large corolla and a long flowering period. It can also produce sweet fruits. Since the pomegranate is a rare yellow flower, it has attracted great attention since its introduction.

First, the characteristics of varieties

1. Botanical characteristics Huanghua Peony The pomegranate flower stretches and flips outward when it is in full bloom, thus forming a larger corolla with a maximum flower diameter of up to 12.6 cm. The appearance resembles an hydrangea and resembles a blooming peony flower. The petals are apricot-yellow when they are first opened, and are yellowish-yellow afterwards. They are unusually elegant and beautiful. After viewing the flowers, they are pleasing to the eye. Even more surprising is the emergence of new flower stamens from the dried flowers after the individual flowers wither and continue to bloom. It is quite festive and auspicious.

2. Biological characteristics Huanghua Peony Pomegranate buds in Mengyin when the temperature reaches above 10°C in early April. It blooms when the temperature reaches 21°C～22°C in the middle and early May of May. The flowering peaks in June and July. Also more, entering the flood season, the number of flowers has decreased. After the beginning of “fall”, the precipitation decreased, the light increased, and it entered a peak of flowering until the temperature dropped in October. From late October to early November, when the temperature drops to 9°C, defoliation begins and the fruit generally matures from late September to early October.

3. Flowering characteristics and fruit traits This type of cultivar grows on one branch in spring or on the second branch in early summer and on branches perennial and results in flowering. The flower bud often grows on the top or below of the current branch. Among them, in which the top flowers are most likely to set fruit, because of the high light, the resulting branches are mostly uniaxially extended. The fruit is oblate or round, the fruit is medium, generally weighs 205-250g, the maximum is 650g, the skin is bright and clean, yellowish-white, the sunny side is flushed, the juice is more, sweet and sour, there is aroma, soluble solids 14 %～16.1%, rich in sugar, vitamins and trace elements.

4. Adaptability and stress-resistance The variety is adaptable, resistant to drought and barren, can be planted in plains and hills, and has strict requirements for soil. It can grow on all kinds of soils with pH 4.5-8.2. Calcined loam or loose texture, nutrient-rich oil sand is best. It is warm and chilly. During the growing season, the temperature above ≥10°C and accumulating temperature above 3000°C is required for normal flowering. When the winter temperature drops to -19°C, the shoots and roots and neck are vulnerable to freezing damage, especially young trees and low-lying lands. The trees that are overgrown with nutrients shall be wrapped with straw ropes (curtains) before the severe cold begins, and the agricultural film shall be outsourced, the earth shall be piled on the base of the trunk, and the canopy shall be sprayed with lime milk to prevent cold.

Second, cultivation management technology

1. Reasonable pruning of this species is sensitive to pruning. After a short cut, it is easy to excite the competing branches. The pruning should be mainly sparse and short, while the saplings should pay less attention to early sparse branching and the results, for all levels. The extension branches of the backbone branches are cut short according to the requirements of pruning, so that the branches can be pumped and the branches can be grown well to cultivate all kinds of branch stems and all kinds of branch groups, and the branches, stems, branches and branches of the internal stems can be timely cut off. , To air and light, combined with growth during the twist tip, picking the heart, take branches, ring cut (stripping) and other measures to promote vegetative growth, early flowering into flowers.

2. Scientific fertilization Water-based basal fertilizer is dominated by organic fertilizers. It is applied before and after defoliation after harvesting fruit in the autumn. Topdressing pre-flowering, post-anthesis, fruit enlargement, and flower bud differentiation are pursued in the early stage. The combined application of nitrogen, phosphorus, and potassium fertilizers in the early stage. In the later stage, phosphorus and potash fertilizers were used as main watering plants to master several key periods before germination, after flowering, and frozen water.

3. Disease and pest control This species has less pests and diseases. It can spray 3 to 5 degrees lime sulfur before germination to eradicate overwintering pests and pathogens; spraying 20% ​​cypermethrin 2000 times solution or fenvalerate during leaf stage. Ester 1500 times, eliminate leaf insect pests; June to August, spraying 50% of carbendazim 600 times to 800 times or 50% of thiophanate-methyl 800 times to prevent dry rot and defoliation; Combined prevention and control of peach aphid can be sprayed with 40% peach Xiaoling 800 times or 50% of phoxim 1000 times.

Third, the development prospects Since ancient times, the Chinese people are particularly respected and respected yellow, yellow represents the noble, is a symbol of sacred and supreme, yellow peonies can be seen, fruit edible, and leaves can absorb the atmosphere of chloride, fluoride And harmful gases in automobile exhaust can purify the air and reduce pollution. It is a kind of garden tree that combines ornamental, edible, landscaping, and environmental protection functions. It can be widely used in garden landscaping to produce high-grade bonsai and the greening of parks and scenic spots. Market prospects.
