1. Cultivation techniques of clove

1.1 propagation techniques

1.1.1 Seed propagation. Seed propagation requires selecting clove plants that are 5 to 6 years old and harvesting and sowing them in time when the fruits are purple. If it is impossible to sow in time, you can store the seeds in fine sand or wet chaff for about 3 months, then remove the flesh and sow them directly with the core.

1.1.2 Cutting propagation. Cuttage propagation is generally carried out about 1 month after flowering, and the flowering branches of more than one month are selected as cuttings. It is required that the number of new buds of cuttings should not be less than 3 pairs, and the length of flowering branch should be 15 cm.

1.1.3 Grafting propagation. Branching and budding are two methods of grafting propagation. In practical application, the most suitable season for branch grafting is autumn and winter, and branch grafting needs to be carried out first. When the branch grafting reaches 80 cm in early spring, it will open.

In order to ensure the good growth of scion in the whole grafting process, it is also necessary to cut off the part 40 cm away from the ground before grafting, and then graft; July is the most suitable period for bud grafting, and the bud about 7 m away from the ground should be selected for grafting, and after grafting, the operation should be protected.

Protection, and the need to remove excess sprouts in time, so that all nutrients can be concentrated to supply the rapid growth of scions, in order to ensure the survival rate of grafting.

1.2 cultivation techniques

1.2.1 Selection of plots. Clove love yang, cold tolerance, bogey ponding. Therefore, when selecting planting plots, good drainage and fertile sandy loam soil is needed, but low-lying and damp should be avoided. It has been shown that cloves grow in shade with slender, fragile branches and produce few, short, loose flowers; they grow slowly and bloom less if the soil is too poor. Therefore, when selecting planting plots, it is suitable for fertile sunny and deep soil conditions.

1.2.2 Fertilizer and water management. There is no excessive fertilizer requirement in the growth process of clove, so it is strictly prohibited to fertilize frequently and excessively in the planting process, otherwise it will affect the formation of flower buds due to excessive growth. Therefore, no fertilizer or a very small amount of fertilizer is generally applied during the growth period. It should be noted that some potassium, nitrogen and phosphorus fertilizers need to be applied after flowering. The total amount of potassium and phosphorus fertilizers needs to be guaranteed not to exceed 75 g, and the amount of nitrogen fertilizer applied is 25 g to ensure the normal growth and development of clove. When watering and fertilizing clove, it should not be too little or too much, and after watering, it should be loosened in time to avoid fertilizer damage, so that the plant can ensure the rapid growth of new buds under the appropriate soil temperature.

1.2.3 Pest control. Planting cloves selects soil with strong drainage, so that the growth environment of cloves is loose and moist. Take effective measures to prevent root rot and the occurrence of pests. Lilac pests have thorn moth, caterpillar, leaf miner, scale insect and big wasp, etc., in the growth process timely and effective control.

2 Application of cloves in greening

Further research on cultivation techniques and application of clove can give full play to its own advantages and enlarge its application scope and strength. Cloves suitable for growth in the sun or semi-shady environment, in addition, relatively humid environment can accelerate the growth of cloves, should not be long-term in the water environment. Syringa has the characteristics of drought tolerance, barren tolerance and cold tolerance, and has strong adaptability, and the occurrence of diseases and insect pests is relatively light. In the planting process, the sunny slope, lawn or roadside can be selected, and it can also be matched with other kinds of flowers and trees in planting, which is not only conducive to the growth and reproduction of clove, but also can improve the ornamental value.

Clove itself has a fragrant fragrance, in front of the window, outside the court is an excellent planting place, and in the planting process can be mixed cultivation of various varieties of clove, build a clove ornamental garden, or clove potted cultivation is a good application choice.

Cloves have good resistance and adsorption of toxic gas, so they 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.
