What kind of plant is this leaf?

Hello, look at the leaves like Du Ying, alias fake bayberry, plum rub rice, green fruit, wild olive, gall eight trees, olives, edge petal Du Ying.

Du Ying evergreen fast-growing tree species, good material, strong adaptability, is an excellent variety of courtyard ornamentation and four seasons greening, born in low mountain valley forests. Seed oil can be used as soap and lubricating oil; The bark of the tree can be used to make dyes.

Rhododendron prefers warm and humid environments, has slightly poor cold tolerance, slightly shade tolerance, well-developed root system, strong germination power, and resistance to pruning. Prefers well-drained, moist, fertile acidic soils. It is suitable for growing in acidic yellow soil and red yellow soil mountainous areas, if it is planted in the plains, it must be well drained, and the growth rate is medium to fast.

1. Sowing

Seed collection and seed treatmentThe mother tree should be selected to be more than 15 days old, robust and disease-free plants, in late October, when the fruit turns from blue-green to dark green, the drupes are ripe, and the seeds should be collected in time.

After the fruit is harvested, it can be stacked in a cool place or soaked in water for 1-2 hours, and after the exocarp is softened, it is scrubbed and washed, and then cleaned with water, and then spread out and dried indoors and stored in time (the seeds should not be exposed to the sun, nor should they be dehydrated and stored dry for a long time).

Most of the seeds of the genus are dormant, and the germination rate (up to 60%) can be significantly improved by storing the seeds in wet sand at low temperature.

2. Water and fertilizer

In the rainy season, ditch cleaning and drainage should be done; Irrigation should be done during the dry season.

At the beginning of seedling growth, thin human feces and urine with a concentration of 3%-5% should be applied every half month. After mid-May, it can be watered with 1% superphosphate or water-soluble fertilizer for sea meals.

During the peak growth period (after mid-June), the seedlings should be done in phases and batches, and the seedlings should be set in late July, and 30-40 square meters should be retained, and nitrogen fertilizer can be stopped in the first half of autumn.

It should be peach leaves, infected with mosaic virus or are deficient, add some nitrogen and zinc fertilizer and spray biological pesticides 30% suspension willow three times.

I see these two leaves as the leaves of a cherry tree.

This is the mirror, also known as the Lotus PalmIt is a plant of the family Sedumaceae, the plant is low, composed of 100 200 fleshy leaves composed of rosette-like leaf disks, and its maximum diameter can reach 50 cm.

Leaves sessile, spoon-shaped, grass green to grayish-green, dark green, leaf margins with white cilia; The leaves all radiate from the center to the periphery, so that the whole leaf disc is as flat as a mirror, without a trace of gaps; Because the leaf margin is slightly darker in color and has white cilia, and the outer leaf is large, the inner leaf leaf is small, so the mirror-like leaf disc is like a beautiful geometric pattern, very beautiful, how to plant the lotus palm?

1. Soil

Lotus palm likes to grow in loose and breathable soil, so we must pay attention to the permeability and drainage of the soil when choosing soil.

The soil can be mixed with honeycomb cinder washed with water and some peat and perlite. In this way, the mixed soil has a certain air permeability, and it can also be directly used with marine fertilization microbial agents, which are rich in 6 kinds of salt-tolerant flora, which is conducive to the growth of lotus palms.

2. Watering

Lotus palm is like a dry environment, drought resistance, avoid stagnant water, in our daily maintenance can follow the principle of "rather dry than wet" to water the lotus palm, spring and autumn two seasons are the growth of the lotus palm season, in the vigorous growth season can keep the pot soil moist, moist is not damp, if the pot soil is too wet, it will cause plant rot roots.

3. Illumination

The disc-leaved lotus palm prefers a bright environment, and cannot be in a shaded environment for a long time, without sufficient light, the leaves will be long, the leaves are not compact, the leaf color is not bright, and it will also cause the leaves to fall off.

In winter, when the light is weaker, the color of the leaves will gradually recover, especially the new leaves that have just grown are more obvious, and the light gradually becomes stronger in spring, and the color of other leaves will slowly recover.

Like fern leaves, it's hard to say which one it is.

Solanum is an annual herb with a height of 30-100 cm. The stems are erect and multi-branched. Leaves ovate, like pepper leaves, 2 5-10 cm long, 1 5-3 cm wide, apex acute, entirety or irregularly wavy coarse, base wedge-shaped, tapering into a stalk; The petiole is up to 2 cm long.

Bright Moon Grass. Its stems and leaves contain a large amount of algin, mannitol, vitamin B, sulfur, potassium and a variety of amino acids. You can take a look at the plant information.

The picture is too small to see clearly, and the leaves look like poplars.

It looks like lilacs, and the leaves of cotton just come out are also like this.

Judging from your **, this one is mosquito repellent vanilla.

Mosquito repellent herb, also known as mosquito repellent grass, belongs to the geranium genus of the yak seedling family Geranium genetically modified evergreen herbaceous plants. It was first a new type of plant cultivated by biologists from the Netherlands and France using cell fusion technology to transfer the genes that can produce citronellal in citronella grass to geraniums, and emitted the mosquito repellent substance citronellal under natural conditions to achieve mosquito repellent effect.

This is the leaf of the citrus plant of the family Rutaceae.

This is called: Single compound leaves:

A type of compound leaf. It resembles a single leaf, but there is a distinct joint between the petiole and the leaf. This distinguishes it from true single leaves, such as the leaves of oranges, oranges, pomelo, etc. The single compound leaves may be caused by the degeneration of two lateral leaflets in the three compound leaves, leaving only one apical leaflet.

Arrow leaf orange arrow leaf orange belongs to the family Rutaceae, citrus genus. Small trees, 4-6 meters high. The branches are long and stiff, the young branches are flat and ridged, and the old branches are nearly cylindrical. Single compound leaves, many oil spots, thick paper, with fine blunt lobed teeth on the leaf body and wing blade edges.

African jasmine.

African jasmine, formerly known as gray lily, is also known as carp gall, gray thorn wood, yellow fruit, small yellow fruit, Latin name: fagraea ceilanica. [1] Native to southern China and Southeast Asia and other countries, it is an evergreen (climbing) shrub or small tree of the genus Nutriaceae, formerly known as C. sinensis (see "Illustrated Guide to Higher Plants of China", "Flora of Yunnan" and other books).

It is similar to the jasmine of the family of Cinnamomum only that the leaves are fragrant to the raw and flowers, because the homonym of the gray lily wood is similar to that of jasmine, and in order to make the name sound good and easy to sell, the florist gave it a new name "African jasmine". It is distributed in southern China and Southeast Asia.

It seems to be the leaves of the southern orange tree...

Generally the wild ones are unknown, maybe you can find them in the Compendium of Materia Medica.
