Efficient cultivation techniques and daily maintenance management of lilac

Today, the editor of Huinong Network has come to take a look at the cultivation techniques of lilacs to see how the flowers with great garden ornamental effect are planted and cultivated, as well as their application in greening.

1 cultivation techniques of cloves

1.1 Propagation technology

1.1.1 seed reproduction. The seed propagation needs to select the remaining clove plants with the age of 5 ~ 6 years, and harvest and sow in time when the fruit is purplish red. If the seeds cannot be sowed in time, the seeds can be stored in fine sand or wet wood chaff for about 3 months, then the pulp will be removed and the seeds can be sown directly.

1.1.2 Cuttage propagation. The cuttage propagation is generally carried out about one month after flowering, and the flower branches which are more than one month after flowering are selected as cuttings. It is required that the new buds of cuttings should not be less than 3 pairs, and the flower branch length is the best in 15cm.

1.1.3 grafting propagation. Branch grafting and bud grafting are two methods of grafting propagation. In practical application, the most suitable season for branch grafting is autumn and winter. Branch grafting needs to be picked and buried first, and branch grafting will grow to 80cm at the beginning of spring.

In order to ensure the good growth of the scion in the whole grafting process, it is necessary to cut off the part other than the 40cm from the ground before the grafting, and then carry on the grafting. July is the most suitable period for bud grafting, where the bud bracts about 7m from the ground are selected for grafting, and the operation place should be protected after the grafting is completed, and the excess tillers need to be removed in time, so that all nutrients can be concentrated to supply the rapid growth of the scion to ensure the survival rate of grafting.

1.2 cultivation techniques

1.2.1 Parcel selection. Cloves like sun, cold and dry, avoid stagnant water. Therefore, when choosing planting plots, sandy loam with good drainage and fertile soil is needed, but low-lying dampness should be avoided. It has been proved that when cloves grow in shady environment, the branches will be slender and fragile, and the flowers will be few and loose; if the planting soil is too barren, they will grow slowly and blossom less. Therefore, when planting a piece of land, it is suitable for the conditions of fertile sunny and deep soil layer.

1.2.2 fertilizer and water management. There are no too many fertilizer requirements in the process of clove growth, so it is forbidden to apply fertilizer frequently and too much in the planting process, otherwise it will affect the formation of flower buds because of excessive growth, so there is generally no fertilization or a very small amount of fertilizer during the growth period. It should be noted that some potash, nitrogen and phosphate fertilizers should be applied after flowering, and the total amount of potash and phosphate fertilizers should not exceed 75g, and the amount of nitrogen fertilizer should be 25g, so as to ensure the normal growth and development of cloves. When watering and fertilizing cloves, it should not be too little or too much, and after watering, the soil should be loosened timely to avoid fertilizer damage, so as to ensure the rapid growth of new buds under the condition of suitable soil temperature.

1.2.3 Pest control. The soil with strong drainage is selected for planting cloves, which makes the growth environment of cloves loose and moist. Take effective measures to prevent root rot and the occurrence of diseases and insect pests. Clove pests include diamondback moth, caterpillar, leaf moth, shell insect and wasp, which are controlled timely and effectively in the process of growth.

Application of clove in greening

In-depth research on the cultivation technology and application of cloves can give full play to the advantages of cloves and increase the scope and intensity of application. Cloves are suitable for growing in sunny or semi-shady environment, in addition, the relatively humid environment can accelerate the growth of cloves, should not be in the stagnant water environment for a long time. Cloves have the characteristics of drought tolerance, barren tolerance and high cold tolerance, with strong adaptability and less occurrence of diseases and insect pests. Choosing sunny slopes, lawns or roadsides in the planting process can also be matched with other kinds of flowers and trees, which is not only conducive to the growth and reproduction of cloves, but also improve the ornamental value.

Lilac itself has a rich fragrance, and it is an excellent planting place in front of the window and out of court, and various varieties of cloves can be mixed and cultivated in the planting process to build a clove ornamental garden. or potted cultivation of cloves is a good application choice.

Cloves have good performance of resistance and adsorption of poison gas, so it can be planted in the factory area, which can effectively improve the ecological environment and the overall air quality of the factory area, and protect the natural environment.

Knowledge of maintenance and management of lilac bonsai

Lilac (Syringaoblata) is a deciduous shrub of Syringa in early spring, which is resistant to drought and cold, likes sunshine and half shade. It is widely cultivated in North China, Northeast and Northwest China. In recent years, it has been moved into the basin for cultivation and ornamental. Lilacs usually blossom in early spring. If properly managed in pots, they can blossom twice and remain in bloom in the coming year.

1. Maintenance and management

Place: cloves like light, usually should be placed in a place with plenty of sunshine and air circulation. However, it is necessary to give a little shade in summer, and high-temperature sunburn is disadvantageous to the growth of potted cloves. In winter, the pot is buried in the outdoor sunny place or in front of the indoor windowsill.

Watering: usually keep the basin soil moist and dry, do not be too wet. High temperature in summer should be watered once in the morning and evening, and less watering should be done after autumn to facilitate dormancy and overwinter.

Fertilization: use rotten cake fertilizer as base fertilizer in winter, and apply cake fertilizer and water every half a month after germination in spring to promote flowering. Summer should also be properly fertilized to facilitate flower bud differentiation and maintain more flowers in the following year. Less fertilizer and water after autumn, too much fertilizer, which is harmful to development.

Pruning: cloves in the growing period, branches and leaves are too dense, should be pruned in time, not only does not interfere with the tree, but also conducive to ventilation and light. When you enter the dormant period after autumn, it is necessary to properly trim, cut off overgrown branches, overlapping branches and cross branches, so that nutrients are concentrated and more pregnant buds are pregnant.

Turn the basin: turn the basin every 2-3 years, combine turning the basin, trim the root system, remove part of the old root and over-long root system, remove the old soil and replace it with newly cultivated soil to facilitate the development of root system and propagation of leaves and flowers.

Pest control: cloves in the case of too wet, easy to produce root rot, light stop growing, heavy withered to death. Clove common pests are domestic antler longicorn beetles, damage to branches, as well as coir moth, diamondback moth, aphids and so on. It can be killed with 40% dimethoate 1500 times liquid spray.

2. Watch

The lilac is beautiful, the flowers are purple and fragrant. Using lobular privet root pile as rootstock to graft cloves into bonsai, with ancient dried flower branches, complement each other, the most ornamental.
