Bougainvillea is an evergreen climbing shrub, which likes warm and humid climate, is not cold resistant, and likes sufficient light. It is often used in hedgerow, garden flowers and trees, etc. So how is the triangle plum cultivated? What good method is there in breeding? What matters should be paid attention to when breeding triangle plum? Please read down with me with your questions!
The best propagation time: the general cutting season is from March to June, Hangzhou is from late May to early June, and cutting is the best before entering the plum.
The best growing soil: Bougainvillea formosana has no strict requirements on soil, can endure barren and drought, and avoid ponding. The sandy soil with rich humus, loose, fertile and strong permeability is better than clay.
Growth humidity requirement: the soil should be kept moist when breeding bougainvillea.
The best growth temperature: the suitable temperature for the growth of Bougainvillea formosana is 15-30 ℃. In summer, shading or water spraying and ventilation measures should be taken. In winter, the ambient temperature should be no less than 5 ℃.
The best growth light: all year round in addition to the new basin of seedlings should be placed in the shade. In winter, it should be placed in front of the south window, and the lighting time should not be less than 8 hours.
Garden planting triangle plum cultivation triangle plum attention: fertilizer: triangle plum need certain nutrients, in the growth period to carry out appropriate fertilization, in order to meet the needs of its growth. The fertilizer should be decomposed, the amount of fertilizer should be a few times, and the concentration should be light, otherwise, it is easy to damage the root system and affect the growth.
Planting in the upper basin: after the survival of Prunus trilobata cuttings, the seedlings survived for 40 days were refined in strong sunlight for a week, and thin fertilizer was poured. After 50-60 days, the cuttings were planted in the basin, and the cuttings were put into the basin. The substrate and the roots were floated away, or the roots were poured out directly. After separation, some of the substrate was planted into the culture soil.
Watering points: the triangle plum should be controlled before flowering, and the principle of "not dry, not watering, watering thoroughly" should be mastered when watering leaves and flowers. However, in order to make the leaf flowers bloom orderly and more, water control must be carried out before flowering. The watering of the leaves and flowers should be controlled from September. Each watering should be carried out after the basin soil is dry and the branches and leaves are soft. It can be repeated for half a month, and then it will return to normal watering after half a month. Do not apply fertilizer during water control period, so as to avoid fertilizer burning root system. In this way, the leaves and flowers can bud and bloom in about one month, and the flowers are orderly and prosperous.
(1) Cuttage Propagation: Cuttage Propagation is the main method of leafy flower propagation. The survival rate of cuttage is high in summer. Annual semi lignified branches should be selected for cuttings, cut into 10-15cm segments, and inserted in sand bed. Under the temperature of 20-25 ℃, the cuttings can take root in 20-25 days. After 40 days, the cuttings can be put into pot and blossom in winter the next year. If treated with hormone before cutting, it can promote rooting and improve survival rate.
(2) High pressure propagation: common layering method can be used for layering, which is usually carried out in spring and autumn. The layering part can be cut first, and then buried in the soil. The temperature above 20 ℃ can be maintained, and the root can be formed in about 20 days.
Pruning Essentials: pruning triangle plum should grasp the principle of "short, heavy and sparse", that is, cutting the horizontal branches short and cutting the new branches again. The dense and weak branches should be removed. The growth of red triangle plum is weak and pruned once a year from March to April; purple triangle plum needs to be pruned twice a year, the first time is before germination in March to April, and the second time is after flower withering and before new branch growth in November to December, so as to ensure vigorous flowering every year.
Basin soil replacement: the growth rate of Bougainvillea rubra is fast, the root system is developed, and there are many fibrous roots, so the basin needs to be changed once a year. Because of long-term watering, fertilizing and rain washing, the basin soil is easy to harden. Therefore, it is necessary to loosen the soil regularly and clear the weeds in the basin soil at the same time, so as to facilitate the growth of triangle plum. Otherwise, the basin soil will harden and accumulate water, which will easily cause root rot or poor growth.
Watering requirements: in spring and autumn, it should be watered once a day. In summer, it can be watered once a day in the morning and evening. In winter, it should be watered once a day in the morning and evening after the emergence of flower buds. At the same time, it should be watered once or twice to the leaf surface. It is necessary to prevent ponding in rainy season to avoid root rot and death.
Pest control: leaf beetle and aphid are the common pests of Bougainvillea rubra, and withered shoot is the common disease. At ordinary times, we should strengthen soil loosening and weeding, remove dead branches and diseased leaves in time, and pay attention to ventilation, so as to reduce the spread of disease sources. Strengthen the examination of the disease, find the disease timely treatment, can use dimethoate, Thiophane and other solutions.
The experience of triangle plum breeding in the park: 1. The temperature in winter is not lower than 5 ℃. Triangle plum can live through the winter safely, otherwise it must be frozen and kept warm or moved into the room for maintenance.
2. Under strong light and high temperature, Prunus triloba grows flowers in water. Triangle plum like strong light and high temperature, not afraid of exposure, but not much water requirements, as long as the basin soil can be kept moist. Especially at the beginning of autumn, water should be made for a month to keep half dry and half wet. It doesn't matter if the leaves fall, but it's good for flowers.
