Is osmanthus a single leaf alternate, and are osmanthus leaves compound or single leafed?

Osmanthus is single-leaved opposite.

Osmanthus is the customary name of many trees of the genus Cinnamomum sinensis, the representative species of Cinnamomum sylvestris, also known as rock osmanthus, is an evergreen shrub or small tree of the family Cinnamomum sylvestris, with firm skin and thin bark, the leaves are oblong and the face is pointed, opposite, and does not wither in winter. Between the leaves of peanuts, the corolla petals are lobed, the shape is small, and there are many kinds of horticultural varieties, the most representative ones are golden cinnamon, silver cinnamon, red cinnamon, laurel and so on.

Osmanthus is one of the top ten famous flowers in Chinese tradition, an excellent garden tree species that integrates greening, beautification and fragrance in one of the ornamental and practical, osmanthus can be dustless, strong and overflowing, can be called a must. Especially in the mid-autumn season, the cong gui is in full bloom, and when the night is quiet and round, the wine is appreciated and the osmanthus is fragrant, which makes people feel refreshed. In ancient Chinese Yonghua poems, the number of Yonggui works is also considerable.

Since ancient times, it has been loved by the Chinese and is regarded as a traditional famous flower.

The leaves of osmanthus are single-leaved and opposite.

Generally, each branch bears a pair of leaves, mainly at the top of the branch and several adjacent nodes below, and the leaf life span is one year. The longer the old leaves survive on the branches, the more beneficial they are for growth and flowering.

Morphological characteristics of osmanthus:

Osmanthus is an evergreen broad-leaved shrub or small tree that is evergreen all year round. Although the roots, shoots, branches, flowers and fruits of different varieties are different, the main shapes are similar. It was observed that there was no obvious taproot of osmanthus flowers, but the lateral roots and fibrous roots were well developed, and the root system was densely distributed in the upper layer.

The buds of osmanthus are often stacked buds, covered with scales, mostly green overlapping buds are divided into branch buds, leaf buds and flower buds, the branches and buds are mixed, including leaf buds and flower buds, mainly distributed in the branch tip section, and the growth and development of leaf buds are synchronized with branch buds.

Osmanthus flower buds are born in the axils of the new shoots of the year, the flower buds have been formed in January, and gradually expanded, and enter the germination period about a month before flowering, Chen Yingqi divided the osmanthus flower buds into six periods, namely the undifferentiated period, the beginning of differentiation, the flower Guangdong differentiation period, the petal differentiation period, the stamens differentiation period, and the pistils differentiation period, and the characteristics of each stage were briefly described Chen Yingqi,. However, they only studied from the perspective of individual flowers, and did not specify the type of variety and bud position sampled. The day before the flower, the flower buds swelled into a bead-shaped, called the bead period the day before the flower, two bud scales were scattered successively, called the day before the parietal shell stage flower, the small flower stalk elongated, called the bell stem stage The day before flowering, the shape of the floret has been developed, some of the small flowers appear pores at the top, there is a fragrance overflowing, called the fragrant eye period The fragrant eye period enters the early flowering period after half a day to one day, the amount of flowering accounts for, it is the best period for flower picking and processing, and the connotation of the flower is fragrant at this time.

The first flowering period lasts for about a few days, that is, it enters the full flowering period, the amount of flowering accounts for the amount, the flower color becomes darker, and the aroma hits people, which is also the key moment for flower picking and processing.

Osmanthus leaves are single-leafed.

A leaf with two or more leaflets on a petiole is called a compound leaflet. For example, locust trees, acacias, and mimosas.

The petiole has only one leaf on it, which is called a single leaf. Poplar, pear tree, Fuso.

How to raise osmanthus to grow well.

1. Watering in a timely manner: The osmanthus pot soil should master the principle of not drying and watering, and watering thoroughly, but spray water on the foliage once a day. After the Qingming Festival, the osmanthus will be moved to the open air to water once, and it must be watered in the morning and evening in summer, and watered around noon in winter, so that the water temperature is close to the soil temperature, so that it will not be cold and hot, and pay attention not to accumulate water.

2. Reasonable fertilization: osmanthus is mainly ornamental flowers, and sufficient fertilizer should be supplied. Nitrogen fertilizer can be applied 1 or 2 times during shoot extraction, and phosphorus fertilizer can be applied mainly before flower bud differentiation and flowering.

Before fertilization, the potting soil should be slightly drier, and it is advisable to loosen the soil first, so as to facilitate the absorption of fertilizer, and it should be watered once the next day of fertilization.

3. Pour the pot for soil: Osmanthus should be potted and changed once every 2 3 years, cut off a part of the old roots and dead roots, and put a layer of river sand or vermiculite at the bottom of the pot to facilitate ventilation and drainage, and place the rotten cake fertilizer or Bika granular fertilizer as the base fertilizer, and the soil must be compacted. The ratio of soil is not very strict, and it can usually be prepared with garden soil, manure and river sand accounting for l 3 each.

4, pruning shaping: osmanthus plastic surgery generally take the method of climbing and pruning combined, should be carried out after autumn, the tree shape is very poor plants can be cut off at 2 3 or 3 4 at the entire top of the branches, the branches are too dense to be thinned, after flowering should also be cut off long branches, dead branches, diseased branches, dense thin branches.

5. Overwintering management: the room temperature of osmanthus should be kept at 0 5 and the relative humidity should be maintained at 50 80%. In winter, the light in the cold room should be good, especially before the buds begin to germinate in early spring, and the sunshine is required.

After leaving the room, it is placed outdoors in a leeward and sunny place, so that it can gradually adapt to the external environment.
