1. Cultivation of Jeraldon wax flowers

1. Jeraldona grows best at 15-35 C, and the area growing the most during the same period of rain and heat.It can withstand a low temperature of minus 3 degrees at a high temperature of more than 40 degrees, but it cannot tolerate the frost. The frost causes the flowers and flower buds to freeze, which affects the quality of the flower. The frost may also cause the seedlings to die.

2. The Jeraldon dharma season likes a warm and humid environment.Like sufficient light, full light or semi -light.

3. Adapting to the land environment with good drying and ventilation, if the plain land should be required to choose sandy soil land with low groundwater Levels and good drainage, it should be planted to endure the dryness of the plant after living.Especially in the rainy season, the root system should be prevented from rotting.When cultivating the seedlings in the seedlings, the Nutritional soil should be prepared: 1/3 0.3%of the potassium dihydrogen phosphate polymaphide is adopted by the field soil.Among them, the latter two are dissolved and entered by spraying. Generally speaking, as long as the transplanting period is transplanted, the survival rate will be very high.

4. After the Jeraldon waxy is purchased by the naked root seedlings when the seedlings are transplanted, they must be placed in a nutritional bowl as soon as possible. It is necessary to place it in the plastic film that is built for about 10 days.There must be a Shading net to control the light.In the small shed to maintain the water of the leaf surface, prevent the leaves from being degraded.Use artificial or automatic spray to replenish air humidity around noon every day.

5. Geraldon's dhahua has few demand for Fertilizer.For most varieties, appropriate nitrogen fertilizer can increase the length of the branches, reduce yellow leaves and abnormal leaves, increase the output of product branches, and extend the life of the bottle.There is no significant impact on the various traits of gold plums.

Second, the trimming and setting of Jeraldon wax flowers

1. The seedlings of Jeraldon's wax flowers do not need to be specially trimmed.For mature plants, trimming is carried out in combination with harvesting.

2. The first trimming is often after its first flowering.If the flower branches that bloom for the first time are short, they can still not be trimmed. If the flower branches are longer, the first trim can be carried out in combination with flowers, but the amount of chopped branches and leaves should be less than 1/2-2/3 of the total amount of leaves. When cutting flowers, you should choose branches with full flowers, yellow leaves and pests, and 20-70%of the flowers.

3. The harvest should be carried out when the temperature is low in the morning. After harvesting, place it in the silver sulfate solution as soon as possible for cushioning to avoid contact with ethylene substances and place them in a 0-2 C environment to be packed in graded.The packaging is used for bandaging. When bandaging, the top tips of the branches are neat. The rubber band at the base should be tightly around a few times, and the branches and leaves on the upper part of the branch should be kept loose.Before packing, the entire bouquet should be immersed in a mixture containing bactericides and paradimetal pesticides. After air -dried air -dried, packets and packing (the best use of a foam box, a few ice cubes should be placed in high temperature in summer.), Immediately Ship or place it at a condition of about 3 C after the packing.

Third, the disease prevention and control of Jeraldon wax flowers

In a more humid climate, the root and rhizome -necked diseases caused by sickle bacteria, soil -deductible bacteria such as fogy and mildew may cause the plant to be harmful.It is important to choose strong seedlings, not to pay attention to water, and to choose soil with good drainage.Gray mold is a disease that often occurs on the petals and leaves that often occur in the wet environment. It can be controlled by spraying in the fields or soaking in the treatment of a sterilized agent such as pushing Hyin.

1. Who invented the first Telescope in the world

In 1608, Hans Lippershey, Midelburg, the Netherlands, created the world's first Telescope.Once, the two children played with a few lenses in front of Li Poore's shop. They watched the trend in the distant church through the two lenses before and after, and they were highly high.Li Populia picked up two lenses and looked at it, and the turbines in the distance were enlarged a lot.Li Poor ran back to the store and put two lenses in a Tube. After many tests, Hans Lee Polm invented the Telescope.In 1608, he applied for a patent for the Telescope he made and followed the requirements of the authorities.It is said that dozens of Telescope glasses in the town claim that the Telescope has been invented, but it is generally believed that Hans Lipor is the inventor of the Telescope.

The news of the Telescope invented quickly spread in European countries. After the news of Italian scientist Galileo learned the news, it made one.The first Telescope can only enlarge the object by 3 times.One month later, the second Telescope he made can be enlarged by 8 times, and the third Telescope can be magnified to 20 times.In October 1609, he made a 30 -fold Telescope.Garri used a self -made Telescope to observe the night sky. For the first time, the surface of the moon was discovered, covering the mountains and the cracks of the crater.Since then, the four satellites of Jupiter and the sunspot movement of Jupiter have been discovered, and the conclusion of the sun is turning.

Second, astronomical Telescope isWho invented

Almost at the same time, German astronomer Capeller also began to study the Telescope. He proposed another astronomical Telescope in "Kither". This Telescope consists of two convex lenses. Unlike Galileo's Telescope, it is wider than Galileo's visual field.But Capeler did not create the Telescope he introduced.This kind of Telescope produced for the first time from 1613 to 1617. He also created a third convex mirror with a third convex mirror in accordance with the suggestion of Cairple.EssenceSaisa made 8 Telescopes and observed the sun one by one. No matter which one can see the same shape of the sun sunspots.Therefore, he dispelled many people who thought that sunspots might be the illusion caused by the dust on the lens, and proved that the sunspots were indeed observed.When observing the sun, Shanya was equipped with a special Shading glass, and Galileo did not add this protection device. As a result, he hurt his eyes and was almost blind.In order to reduce the color difference between the refraction Telescope in the Netherlands, the color difference between the refraction Telescope made a Telescope with a length of nearly 6 meters in 1665 to explore the halo of Saturn. Later, it made a nearly 41 -meter -long Telescope.

Third, who was invented by reflecting Telescope

In 1793, William Herschel, the system made a reflective Telescope with a diameter of 130 cm in the diameter and made of copper tin alloy, weighing 1 ton.

In 1845, the reflex Telescope made by William Parsons in Britain, with a diameter of 1.82 meters.

In 1917, Hooker Telescope was completed in Wilson Observatory, California, USA.Its main reflexive diameter is 100 inches.It was using this Telescope that Edwin Hubble discovered the amazing fact that the universe was expanding.

Fourth, who invented the refractive Telescope

In 1930, the German Bernhardschmidt will reflect the advantages of refraction Telescope and reflecting Telescope (the refractive Telescope image is small but the color difference and the larger the size, the more expensive the reflected Telescope, the low cost, and the reflex mirror can be made very large.But the existence) combined into the first reflection Telescope.

After the war, the reflective Telescope developed rapidly in astronomical observations. In 1950, a Hale reflecting Telescope was installed on the Paloma Mountain.

In 1969, a 6 -meter -diameter reflex mirror was installed on Mount Pastulfv in the former Soviet Union.

In 1990, NASA sent the Hubble Space Telescope into the track. However, due to the mirror fault, the Hubble Telescope did not fully play its role until 1993 that the astronauts completed the space repair and replaced the lens.Because it can not be disturbed by the atmosphere of the earth, the image clarity of the Hubble Telescope is 10 times that of the image of similar Telescopes on the earth.

In 1993, the United States built a "Kake Telescope" with a caliber of 10 meters on the Monakia Mountain in Hawaii. Its mirror was composed of 36 1.8 meters of reflectors.

In 2001, the European Southern Observatory in Chile developed the "Very Large Telescope" (VLT), which consists of 4 Telescopes with a diameter of 8 meters. Its conservation capacity is equivalent to a 16 -meter reflected Telescope.

On June 18, 2014, the top of Cerro Amazones, Chile, was used to place the world's largest power Telescope "European Grand Astronomy" (English abbreviation E-art).Salo Amazon is located in the Atacama Desert with an altitude of 3,000 meters.E-In the Eye of the world, the "largest sky in the world", is nearly 40 meters wide and weighs about 2,500 tons. Its brightness is 15 times higher than that of a long-distance mirror, and its clarity is 16 times that of the Hubble Telescope.The Telescope costs 879 million pounds (about 9.3 billion yuan), which is expected to be officially put into use in 2022.

A group of Telescopes that were under construction began to impact the white giant brothers on the Monakia Mountain.These new competitors include the 30 -meter -caliber "Thirty Meter Telescope (TMT), 20 -meter -caliber Giant Magellan Telescope (GMT) and a 100 -meter -caliber (GMT).Overwhelming Large Telescope, referred to as OWL).Their initiative pointed out that these new Telescope can not only provide space pictures like a photo of the Hubble Telescope, but also collect more light.There are more understanding and see the planets around the distant stars.

1. What is the material of the mesh suspension

There are many Hammock materials. The most common ones are fabric materials, such as canvas, parachute cloth, etc. Some are also a mesh suspension. So what is the material of the mesh suspension?

The mesh suspension is also called the nylon Hammock. It is made of nylon mesh. nylon net is a chemical fiber woven net with chemical fibers such as nylon wire, nylon wire, polyester silk, and Narun silk.Formed, it has the characteristics of high toughness, good elasticity, corrosion resistance, oil resistance, water resistance, wear resistance, high temperature resistance, weather resistance and other characteristics. In addition to making suspension, it is also widely used in industrial filtration, oil, chemical, printing and other fields.

Second, the suspension mesh is good or good canvas

The mesh suspension and canvas hammocks are suspension of two different material fabrics. In addition to the differences in material, the two are also different in terms of experience and comfort. So which one is the best mesh suspension and canvas suspender?

1. canvas suspension is a fabric of traditional manufacturing suspension. Its biggest advantage is softness and comfort, large bearing gravity, easy to clean, and it is more comfortable to lie down. The disadvantage is that the moisture resistance is poor and the breathability is worse.

2. The advantage of mesh suspension is that the breathability is very good and the heat dissipation performance is better. The disadvantage is that the comfort of lying on the lay down is average, and if a friend with a relatively large weight is lying up, it is easy to have a trace, and the public occasion will be a bit embarrassing.

Generally speaking, the canvas hammocks and mesh suspension have their own advantages and disadvantages. Generally, it is better to use a mesh suspension by the seaside, the lakeside, the poolside and the weather.Essence

The second point is that after each grilled food is baked, it must be cleaned once, thoroughly cleaned the oil and carbon dirt, and then baked the next food.The third point is that after all the barbecue work was over that day, a thorough cleaning work was done to ensure that the barbecue work the next day was carried out normally.

The fourth point, you can use the oil -removing cleaner to be sprayed directly when the oil -removing cleaner is used to be used. After waiting for a few minutes, you can easily remove the oil with a wet cloth or paper towel.Or use vinegar to soak it, and then brush it with a steel wire. The more commonly used method is to wipe it with a wire ball.

The cleaning and maintenance of the barbecue rack is ready, and it will be handy when it operates. Diners can eat nutritious and assured barbecue foods. If you can make first -class characteristic barbecue foods, then barbecue operators make money without worry.

1. The breeding method of red bird coral

1. Environment

Red bird corals have strict requirements on light. During the usual period of maintenance, they must be placed in the astigmatism in the soft light, and the season should be avoided to the strong light; the control temperature is about 16-27 C.Otherwise it will be frostbite.

2. Water

Red bird coral is a fleshy root plant. Do not water too much water during the growth. It is best to wait until the pot soil is dry. The watering should be reduced in winter, and the water content of the soil is about 40%.After the soil is turned to facilitate the absorption of the root system.

3. Fertilization

Red bird coral grows quickly in the matrix with sufficient nutrients. If the base Fertilizer is sufficient, Fertilizer does not need to be applied during the growth period, otherwise it will apply a thin Compound fertilizer solution every one month.Dilute the water after fertilization, which is conducive to the absorption of the root system.

4. Pruning

The growth of red bird corals is very strong. In winter, the plant is in a dormant period. At this time, appropriate trimming can be performed;To increase the ventilation of the canopy.

2. precautions for breeding of red bird corals

1. It is best to carry out pots in spring. At this time, it is conducive to the survival of the plant, and it must be carried out in combination with trimming.The top part of the plant should be cut in time to promote branches, and the root ball should be properly trimmed.

2. The common pests in red bird corals are mainly harm of leaf spots, anthracnose, scale insects, and aphids. They are more harmful. They can be cut off when the disease is onset.The loose emulsion solution can be sprayed and controlled.

Third, can red bird coral be raised at home?

Red bird corals can be cultivated at home, but they cannot be placed in small and low places such as bedrooms.Because once it breaks, it will flow out a white liquid with a faint toxin. If you accidentally encounter it, it will cause itching of the Skin. You must rinse with a lot of water. In severe cases, it will cause symptoms such as vomiting and dizziness.Essence
