Breeding methods in coral bean
Potted winter coral requires loose and fertile sandy loam with good drainage and rich organic matter, and 5% cake-retting fertilizer or chicken and duck manure is added. Spraying new high-fat film after transplanting seedlings into pots can effectively prevent evaporation and transpiration of aboveground water, isolate pests and diseases, shorten the slow seedling stage, quickly adapt to the new environment and grow healthily.
After surviving in the slow seedling stage, water normally, loosen the soil and fertilize once every half month to keep the soil moist. And give enough light, when the plant reaches the height of 10 cm, heading and coring are carried out to promote germination. Spraying Zhuhuawang 3 can transform the vegetative growth of plants into reproductive nutrition, inhibit the overgrowth of main shoots and promote the differentiation of flower buds.
Winter coral likes sunny, warm and sunny environment, and the suitable growth temperature is18-25℃; Not drought-tolerant, avoid water and be afraid of waterlogging. The soil needs a good drainage system. Fertile and loose soil is needed. Winter coral grows vigorously and is easy to cultivate and manage. Keep the soil moist during the growing season, and apply diluted fertilizer and decomposed sheep manure water once every two weeks.
In the hot summer season, it is forbidden to be washed away by thunderstorms at noon. After the disease is washed away by rain, it is easy to atrophy and die. When the summer rainfall is high and boundless, the planted plants are prone to anthracnose, but the ground planting is less affected. Therefore, plants can be transplanted to the ground in summer, then planted in pots with soil in September, and cultivated indoors in late June, 65438+ 10, and the room temperature should not be lower than 5℃, which is conducive to their safe wintering. Coral in winter is beautiful without pruning. However, for biennial cultivation, in order to control the height of the plant and the ventilation and light transmission in the plant, some branches should be thinned from the plant when changing pots in the next spring.
Morphological characteristics of coral bean
Erect branched small shrub, 0.3- 1.5 m high, the branchlets are dendritic tufted when they are young, and then gradually fall off. The leaves are twins, different in size, elliptic-lanceolate, 2-5 cm long or slightly longer, 1- 1.5 cm wide or slightly wider, with a blunt or short tip, a wedge-shaped base extending downward into a short stalk, and the leaves are hairless. There are often dendritic villi along the veins under the leaves, which are completely or slightly wavy, and the midvein protrudes downward, with 4-7 lateral veins on each side. The petiole is about 2-5 mm long, and it is dendritic when it is young, and then it gradually falls off. Inflorescence is short, axillary, usually 1-3 flowers, solitary or scorpion-tailed, the total pedicel is almost short, the pedicel is about 5 mm long, the flowers are small, and the diameter is about 8-10 mm; Calyx green, 5-parted, lobes ovate-lanceolate, obtuse, about 5 mm long, corolla white, tube hidden in calyx, about 65438 0.5 mm long, crown about 6.5-8.5 mm long, 5-parted, lobes ovoid, about 4-6 mm long, about 4 mm wide, pointed or obtuse; Filaments are about 65438±0mm long, anthers are oblong, about twice as long as filaments, and apical pores are slightly inward; The ovary is nearly round, the diameter is about 65438±0.5mm, the style is about 4-6 mm long, and the stigma is truncated. Berries are solitary, spherical, coral red or orange, with a diameter of 1-2 cm; Seeds flat, about 3 mm in diameter. The flowering period is April-July, and the fruit maturity is August-65438+February.
Reproductive management in coral bean
Seed propagation is the most commonly used. Ripe berries are collected in winter and spring, washed in water, taken out, dried and stored for seeds. Sow the stored seeds in indoor shallow pots in spring. Seeded flowers germinate quickly, neatly and grow quickly. After the seedlings grow 3-4 leaves, they should be replaced with pots of 10 cm or transplanted to open seedbeds.
Coral bean likes warm sunshine and well-drained soil. Plant one plant in each pot, water the roots after planting and put it in the shade. After seedling extension, transplant to a sunny place. 1~2 months later, when the plant grows to 25~30 cm high and the root system is full, the pot can be changed. Transplanted in an open seedbed with a plant spacing of 10 cm, and then planted with a plant spacing of 30 cm after it grows to plant length and leaves between plants are sealed. In summer, potted plants are affected by high temperature and drought, and anthracnose is prone to occur in high temperature and rainy days. Ground planting can avoid these adverse effects. After the arrival of early autumn in August, it will be planted in a 7-inch flowerpot with soil. During the growth period, attention should be paid to shaping, so that the base of the plant will grow into an independent trunk with a height of 15~20 cm, and a small crown will be formed on the upper part. When coral bean seedlings grow to 20 cm high, the top center should be removed, and the lower lateral branches should be erased to form short stems, so as to promote the occurrence of lateral buds in the middle of the main branches. When the lateral branches grow to 25 cm, a heart shape should be made, which can produce more lateral branches and increase the fruit-setting parts. If perennial plants are to be cultivated, all the lateral branches should be cut short after the fruit falls off every winter, and the length of the lateral branches is about 15 cm. If properly pruned, the annual fruit yield of plants over three years can reach dozens to hundreds, which greatly improves the ornamental value of coral bean. In areas where the temperature is warmer in winter, coral bean can spend the winter outdoors, and the northern area should be moved to a low-temperature greenhouse. When the axillary buds begin to sprout the next spring, they should be pruned. Only three or four buds are left at the lower part of the main branch and the side branch, and the rest are all cut off, and the new year's maintenance is carried out in combination with changing pots. In order to ensure normal growth, flowering and fruiting, decomposed liquid fertilizer is applied 2~3 times a month. When damping-off occurs at seedling stage, zineb solution with 600 times concentration or 0. 1%~0.2% copper sulfate solution should be pulled out and sprayed in time.
