Who knows the habits of azaleas?

Share the bits and pieces of life.

Rhododendron prefers cool, humid climate, avoid hot and dry Rhododendron genus has many species, with great differences, including evergreen large trees, small trees, evergreen shrubs and deciduous shrubs. Habits vary greatly, but most of them are produced at high altitudes, preferring cool, humid climates and avoiding extreme heat and dryness. Acidic soils rich in humus, loose, moist, and pH between are required.

Some species and horticultural varieties are more adaptable, drought tolerant, barren, and can grow with a soil pH value between 7 and 8. Rhododendron has certain requirements for light, but it is not resistant to sunlight, and there should be trees or shade canopies in summer and autumn to protect from the scorching sun.

Rhododendron growth habits.

1.Growing temperature: Rhododendron grows well at 15-25.

2.Light-loving: Rhododendron is suitable for growing in places with weak sunlight and spine sheds.

3.Humidity: Rhododendron prefers high humidity in flower soil and air during the growing season.

5. Fertile soil: Rhododendron loam soil is the soil that grows well on the fertile soil of flowers.

Features of the shape of the azalea.

Rhododendron is a deciduous semi-evergreen shrub with many branches. The young branches have reddish-brown hairs, and the old cherry branches are grayish-yellow. 1.

Leaf shape: Rhododendron leaves are short, paper-like in spring, leather-like in summer, and oval, lanceolate as a whole. But the flower shape of azaleas varies from variety to variety.

2.Flowering period: When the azaleas are in full bloom, they are colorful and have a large number of flowers.

They bloom first and then grow leaves. So the mountains of rhododendrons in spring look beautiful.

Environmental conditions for the growth of rhododendrons.

The azalea at an altitude of 800 meters above sea level in Yunnan is located in the western part of Yunnan, with 4,500 meters of high mountains, middle mountains, low mountains, and fields. Alpine types are the most abundant, especially in alpine and humid areas.

Rhododendron growth process.

The dormant period of rhododendrons begins in November and ends in February of the following year, when water requirements are minimal. Every March, the rhododendrons begin to sprout and grow, and the water requirements increase. Water every 1-2 days on sunny days.

From March to August, the azaleas are in full bloom, sprouting new shoots and full of vitality; From early July to early September, water every morning, spray water on the leaves and ground at noon to maintain environmental humidity; From mid-May to October, the new shoots of the azaleas stop growing and begin to branch. The soil in the pot should be slightly dry, and it is generally watered every 2 days in the morning.

Potted rhododendron cultivation points.

1.Soil: Potted azaleas should be planted in acidic soil.

In addition, the soil should be breathable and well-drained. Clay or alkaline soils should not be used. 2.

Temperature: Potted azaleas prefer a warm environment, and the room temperature is generally not lower than 10 degrees in winter. If the temperature is too high, the azaleas will stop growing.

3.Watering: When potted azaleas are in full bloom, water more often in the summer.

Rhododendron naturally prefers a humid environment, so it is necessary to maintain adequate water when flowering and to water it once a night. Water once a day in the summer. Water every 4 days in spring and autumn is sufficient.

4.Sunlight: Potted rhododendrons should not be overexposed.

They should be shaded by the sun so as not to burn the foliage, but the specific sunlight should also change with the seasons.

Rhododendron growth habits.

1. Growth temperature: Rhododendron grows well in an environment of 15-25. Years of excitement.

2. Light-loving: Rhododendron is suitable for growing in places with weak sunlight.

3. Moisture-loving: In the growing season, rhododendrons like high humidity soil and air environment.

5. Fertile soil: Rhododendron loaf soil is the soil that grows well on the fertile soil of flowers.

Features of the shape of the azalea.

Rhododendron is a deciduous semi-evergreen shrub plant with many branches, young branches with reddish-brown hairs, and grayish-yellow old branches.

1. Leaf type: Rhododendron has short leaves, paper-shaped in spring, leather-shaped in summer, and ovate-lanceolate as a whole. However, depending on the rhododendron species, the flower shape will also change.

2. Flowering period: When the azaleas are in full bloom, they are colorful and have more flowers, and they bloom first and then grow leaves, so the rhododendrons that are full of mountains in spring look beautiful.

Environmental conditions for the growth of rhododendrons.

The rhododendron at an altitude of 800 meters above sea level in Yunnan is in the western part of Yunnan, 4,500 meters of high mountains, middle mountains, low hills and fields, and the species of high mountains are the most abundant, especially in the cold and humid areas of high mountains.

Rhododendron growth process.

The dormant period of the azalea starts in November and lasts in February, when the water requirement is very low, and in March every year, the rhododendron begins to germinate and grow, and the water requirement also increases, and the socks are usually watered every 1-2 days on sunny days. From March to August, the rhododendrons are in full bloom, germinating new shoots and full of vitality; From July to early September, water once a day in the morning, spray water on the leaves and the ground at noon to maintain ambient humidity; From mid-May to October, the new shoots of azaleas stop growing and begin to branch, and the potting soil should be slightly dry, generally watered every 2 days in the morning.

Potted rhododendron cultivation points.

1. Soil: Acidic soil should be used for rhododendron potted plants, and the soil should be guaranteed to be breathable and well drained, and clay or alkaline soil should not be used.

2. Temperature: Potted azaleas like a warm environment, and the room temperature in winter can generally not be lower than 10 degrees, and the rhododendron will stop growing if the temperature is too high.

3. Watering: When potted azaleas are in full bloom, they should be watered more in summer, azaleas originally like a humid environment, and should be watered once a day at night to maintain sufficient water when the flowers bloom. It should be watered once a day in the summer. Spring and autumn can be watered every 4 days.

4. Sunlight: Potted rhododendrons should not be excessively exposed to the sun, and should be shaded in the sun to avoid burning the branches and leaves, but the specific sunlight should also change with the season.

Rhododendron grows at an altitude of 500-1200 (-2500) meters above sea level in mountainous shrubs or pine forests, prefers acidic soils, and does not grow well in calcareous soils, or even does not grow at all. For this reason, soil scientists often use the rhododendron as an indicator crop for acidic soils.

Rhododendron likes cool, moist, ventilated semi-shaded environment, both afraid of heat and cold, the growth temperature is 12 to 25, the summer temperature is more than 35, then the new shoots, new leaves grow slowly, in a semi-dormant state. In summer, you should protect yourself from the sun and shade, and in winter, you should pay attention to keeping warm and cold.

Avoid scorching sun exposure, suitable for growing under the scattered light with little light intensity, too strong light, young leaves are easy to be burned, new leaves and old leaves are scorched, and in severe cases, it will lead to plant death. In winter, rhododendrons cultivated in the open field should take measures to protect them from the cold to ensure their safe wintering. Among the ornamental rhododendrons, C. westeroptera has the weakest cold resistance, and the temperature drops below 0 and is prone to frost damage.

The cuckoo is a typical nest parasitic bird, it does not build a nest, does not incubate eggs, and does not nurse young birds. All this work is done by the little cuckoo's stepparents. At the turn of spring and summer, before the female cuckoo is about to lay eggs, she will carefully look for the nests of thrushes, reed warblers and other small birds, and after choosing a target, she will take advantage of her similar shape, size and body color to similar birds of prey, and fly from a distance.

The cuckoo's flying posture also resembles that of the raptor rock harrier; Fly very low, one moment to the left, the next to the right with sharp turns. Occasionally, they flapped their wings and flapped them loudly to intimidate the birds that were incubating their eggs. When the little bird that was incubating its eggs saw the figure of the bird of prey soaring low in the sky, and was so frightened that it abandoned its home and fled for its life, the cuckoo achieved its purpose of intimidation.

The cuckoo lays the eggs in the nest he has chosen, and then carefully places the eggs between the eggs of the other birds with his beak. Before releasing their own eggs, cuckoos will often go out of their way to take one of other people's eggs from the nest (eat or throw them away).

The cuckoo is many times larger than some small birds, but the eggs it lays are very small, and the cuckoo eggs are strikingly similar to the eggs in the nest it chooses in terms of shape, color and so on (the result of natural selection) In this way, it is difficult for other birds to distinguish the real from the fake. Although small, cuckoo eggs develop quickly and tend to hatch earlier or at the same time than the eggs of the nest master. As soon as the little cuckoo was born, he engaged in "evil deeds", supported it with its undeveloped wings, and carefully crawled towards the nest.

It lowers its head, puts its forehead against the bottom of the nest, and pushes its stepmother's child, the chick (or egg), out of the nest. Then he murdered the other little ones. When the stepmother came back, she didn't know what the little cuckoo had done, and saw that there was only one chick left in the nest, and when her own darling came to love, she carefully nursed the little cuckoo.

When the little cuckoo is plump, it leaves without saying goodbye and flies away.

Although the rhododendron has a bad brooding habit, it is a well-known bird that eats pine caterpillars, the great enemy of pine trees. Pine caterpillars are a pest that many birds don't like to eat, but cuckoos prefer their deliciousness. It has been observed that a single cuckoo can prey on more than 100 caterpillars per hour.

In addition, the rhododendron also eats other agricultural and forestry pests, so it is also called "forest guard".

In a pond or in a place overgrown with reeds, it is not uncommon to see a huge bird, following behind a mother many times smaller than him (in fact, its stepmother), opening its mouth wide and waiting for the petite mother to keep and painstakingly catching insects to satisfy its huge appetite. The big bird is the cuckoo, the pocket bird, the bird that has inadvertently become a stepmother (mostly thrushes or reed warblers.

Cuckoo birds have the following habits:

1. Growth and reproduction.

Osteoparasitic cuckoos lay their eggs in the nests of other birds, and are generally born earlier than other birds, as soon as the cuckoo is born, the cuckoo eggs are pushed out of the nest and fed by the adoptive parents. Ground cuckoos nest in low vegetation with tree branches. Both females and males participate in egg holding and brooding.

Second, the characteristics of life.

Cuckoos can help humans eliminate pests, such as beetle worms, kale maggots, kowtow insects, etc. are all food for cuckoos, especially like to eat pine caterpillars, so cuckoos are known as "forest guardians", so people regard cuckoos as beneficial birds.
