Propagation methods of clove flowers

The propagation methods of clove flowers are divided into plant division, striping, grafting, cutting and sowing, etc., and the propagation methods of lilac flowers are as common as sowing and plant division.

Sowing takes place in early April. Soak the seeds in hot water at 40 degrees Celsius and 50 degrees Celsius for 2 hours, remove them and mix them with a portion of sand, place them in a sunny place, cover them with straw bags or gunny bags, and water them frequently to keep them moist. After about a week, the seeds can germinate and then sow.

Ramet can be carried out in March or November. As long as the stems and branches from the roots of the mother plant are separated, they can be transplanted separately. Cutting should be carried out in autumn. Ligustrum lucidum and water wax trees are mostly used as rootstocks, and the method of high grafting is carried out. The buds and scions are selected from the mother plants of superior varieties. Also pay attention to cut off the new branches and buds of the anvil at any time, so as not to consume nutrition and make the buds and scions dysplastic and dominate. It would be better for striping propagation to be carried out in February. When pressing the strip, the coarse branches should be girdled. The strips can blossom for 2-3 years after survival.

Lilacs can be planted or potted. When transplanting, the root should carry as much soil as possible, so that it is easy to survive.

Lilac sex like sunshine, slightly shade, like moisture, avoid stagnant water, cold and drought resistance,-generally do not need more watering. It requires fertile sandy loam with good drainage. If planted in a shady environment, the branches are slender and weak, the inflorescences are short and loose, and the flowers are not glossy. If planted on barren land, it can grow, but the flowers are not small, and the growth is thin. Therefore, it is appropriate to plant in the sunny, fertile, deep soil.

When planting, it is necessary to bring soil clots, cut off some branches appropriately, and pour enough water after planting. After that, when the weather is dry in spring every year, the buds should be watered before and after flowering. Cloves do not like big fertilizer, do not fertilize too much, otherwise it is easy to cause overgrowth and affect flowering. The nutrients in the soil can be replenished by applying sub-mature compost every year or before the beginning of winter. After the flower fade, if there is no seed, the residual flower together with the two buds in the lower part of the flower ear can be cut off, and some of the dense branches can be removed at the same time, which is beneficial to ventilation, light and beautiful tree shape, and to promote the germination of new branches and the formation of flower buds.

After defoliation, disease and insect branches, withered branches and slender branches can be cut off, and cross branches, overgrown branches, overlapping branches and over-dense branches can be properly truncated to make the branches evenly distributed and keep the crown round for the growth and flowering of the following year. Cloves are planted in the ground, and special attention should be paid to drainage and waterlogging in the rainy season. Because of stagnant water for too long, it is easy to die of fallen leaves.

The culture method of lilac 1. Planting method

We need to plant lilacs in a sunny place with good ventilation and good light. We choose the planting time in spring, the flower distance between each lilac is about three meters, the plant is cultured for more than 2 years, the planting hole is bigger, 65~85cm is about, deep 55~65cm

100 grams of fully mature organic fertilizer and 100-150 grams of bone meal were applied to each hole, which were fully mixed with the soil as base fertilizer.

two。 Watering

Water it in time after planting, and then water it every other week in the future. Watering varies according to different climates in different regions. In North China, cloves grow vigorously and blossom from April to June. They should be watered 2-3 times a month. After July, they enter the rainy season. Pay attention to drainage and waterlogging prevention. We should pay attention to the lack of drought tolerance of lilac flowers, and we should water them in time.

3. Pruning

Generally, pruning is carried out before the peak growth period in spring, mainly for fine, weak and over-dense branches.

4. Fertilizer application

Clove flowers do not have high requirements for fertilizer, generally we choose not to apply fertilizer, too much fertilization will affect the normal growth of lilac flowers. However, we can apply some phosphorus, potassium and nitrogen fertilizer after flowering to ensure the normal growth of the plant after falling flowers.

Culture methods of clove flowers

Clove flower is a general term for deciduous shrubs or small trees of the genus Oleaceae. Many kinds of flowers are raw materials for extracting flavors and preparing high-grade spices, and their branches and leaves are luxuriant, and the flowers are elegant and fragrant, so the garden is widely cultivated for viewing and is a treasure in the garden. Let's take a look at the cultivation methods of lilac flowers.

Growth habits of lilac

Lilacs like light, warm, moist and sunny, slightly resistant to shade, weak growth in shade or semi-shade, rare flowering, cold tolerance and strong drought tolerance. Lax requirements on the soil, resistance to barren, like fertile, well-drained soil, avoid planting in low-lying land, stagnant water will cause disease, until the death of the whole plant. After defoliation, bare roots were transplanted before germination, and sunny places with fertile soil and good drainage were selected for planting, mainly distributed in subtropical subalpine, hillside forest edge from warm temperate zone to temperate zone, under forest and sunny shrub in cold temperate zone.

Propagation methods of clove flowers

1. Grafting: grafting is the main method of propagation, which can be done by bud grafting or branch grafting. European cloves or lobular privet are mostly used in rootstocks, and bud grafting is usually carried out from late June to mid-July in North China. The scion selected the full dormant buds on the healthy branches of the year, grafted with shield buds without xylem and connected to the trunk of the rootstock 5 centimeters and 10 centimeters above the ground.

2. Sowing: it can be sowed in indoor pot or open field in spring and autumn. Spring sowing is the best in the north. Cold room pot sowing is carried out in late March, the temperature is maintained at 10: 22 ℃, seedlings can emerge in 14: 25 days, and the seedling emergence rate is 40: 90%. Spring sowing in the open field can be carried out from late March to early April. Before sowing, the seeds should be stored in sand for 2 months under the condition of 0: 7 ℃, and the seedlings will emerge half a month after sowing.

3. Cuttings: one month after flowering, the semi-lignified sturdy branches of the same year can be selected as cuttings, the cuttings are about 15 cm long, treated with 50~100PPM indolebutyric acid aqueous solution for 15 hours, and covered with plastic film after cutting. after 1 month, they can take root, and the rooting rate is up to 80%. Lignified branches can also be taken in autumn and winter for cuttings, generally buried in the open field, and cut in the following spring.

Culture methods of clove flowers

1. Planting: cloves should be planted in sunny places with loose soil and good drainage. Generally, bare roots are planted before sprouting branches in spring, with a distance of 3 meters. The hole diameter of 2-year-old 3-year-old seedlings should be 70-80 cm and the depth should be 50-60 cm. 100 grams of fully mature organic fertilizer and 100 grams of 150 grams of bone meal were applied to each hole, which were fully mixed with the soil as base fertilizer.

2. Watering: water cloves thoroughly after planting, and then water the river every 10 days. Loosen the soil and preserve soil moisture after each watering. Irrigation can vary from April to June in North China, which is the season for cloves to grow vigorously and blossom. It is necessary to irrigate 2 or 3 times a month. When the rainy season enters after July, attention should be paid to drainage and waterlogging, and sufficient water should be irrigated before winter begins in mid-November.

3. Pruning: cloves are planted with 3-4-year-old seedlings, and the branches on the ground should be strongly pruned, usually cut off from 30 cm above the ground, and luxuriant flowers can bloom in the second year. Pruning is carried out before sprouting in spring, mainly cutting off the thin and weak branches and overdense branches, and reasonably retaining the regeneration branches. The residual spike should be cut off after flowering.

4, fertilization: cloves generally do not apply fertilizer or only apply a small amount of fertilizer, do not apply too much fertilizer, otherwise it will cause overgrowth, fir and affect the formation of flower buds, on the other hand, reduce flowering. But some phosphorus, potash and nitrogen fertilizer should be applied after flowering.

5. Diseases and insects: the diseases of cloves include bacterial or fungal diseases, such as Fusarium wilt, leaf blight, wilt, etc., as well as diseases caused by viruses, which usually occur in the period of high temperature and humidity in summer. Pests include caterpillars, diamondback moths, leaf moths, wasps, shell insects and so on.
