1. Will Solar street lights be on during the day?

The street lights are generally light at night, and Solar street lights are no exception. Under normal circumstances, Solar street lights will not light up during the day.

During the day, Solar lamps are a state of absorption. When the night is darker, and the requirements of the Solar street lights are light, it will start to light up to meet the normal use at night.Generally, Solar street lights control the switch through voltage. If there are some special circumstances, the output voltage of the Solar street lights is lower. In the set value, the Solar street light will also glow during the day.

2. What is the reason why Solar street lights have been on during the day

Normal Solar street lights will not light up during the day. If the Lights are on during the day, it means that the Solar street lights are broken, and there are many reasons that may cause this situation:

1. The Solar panel does not pass the controller to charge the battery during the day

The controller detection: The red light on the controller indicates that it is charging, and the red light shining indicates that the battery is now full, and the controller is charging with a small current of the pulse.

Solar panels: If the connection of Solar panels is not very strong, it will not be able to charge normally. Generally, there is a voltage (voltage meter test), the normal opening voltage is above 17.5V; but there is no current.This phenomenon is that the wires of the battery plate are not connected (virtual welding or unconnected joints). After the investigation method can be opened directly at the black electrical cover behind the battery plate, and directly use the voltage and current meter to detect the data.If there is no current from the aluminum pool detection directly from the battery plate, it means that the battery board has problems to be replaced.

2. Object cover

If the Solar panel is covered, it will also cause Solar street lights to be unable to use normally, covering snow, and the cover of dust.When these masks cover the Solar panels, the output voltage of the Solar panel will be lower than the certain value, and the Solar street light will be triggered.

3. Optical resistance control control

The light -sensitive resistance is particularly sensitive to light. When the light is weak, the resistance is large, and the resistance value decreases as the light becomes stronger.After sliding the resistor, a balance point can be found. When the light is strong, the light resistance value is small.The use of photovoltaic resistance has certain disadvantages.The light -sensitive resistance has high requirements for installation, and it is prone to accidental control under rainy days, cloudy and other conditions.

4. The voltage of Solar panels is wrong

The Solar panel transforms the Solar light into electrical energy. The stronger the light, the higher the output voltage, and the weaker the light, the lower the light.Therefore, many Solar street lights use the output voltage of the battery plate as the control signal. When the voltage is lower than a certain degree, the street light is turned on, and the street light is turned off when the voltage is higher than a certain degree.If there is a problem with the voltage of the Solar panel, when it is lower than a certain degree, the Lights will be turned on during the day.

The difference between plum blossoms and peach blossoms

1,color

The color types of plum blossoms are relatively complicated, red, yellow and white, etc., and the color of peach blossoms is relatively bright, but the types are relatively single, mostly pink, and rarely pale white.

2, See if there are leaves when flowering

The characteristic of plum blossoms is that the flowers are blooming first and then growing the leaves, so it must be plum blossoms when the flowers are blooming; and peach blossoms are coexisting in the coexistence of flowers and leaves.It's peach blossom.

3Judging through the growth of the tree

The plum tree is slightly short, the height is generally five or six meters, and the color of its trunk is mostly pale gray; and the peach tree is higher than the highest level of the plum tree, which can grow to6to8Mi, the trunk is mostly rough, mainly gray -brown.

4Judgment based on flowering time

The flowering time of plum blossoms and peach blossoms is different.plum blossoms are generally opened in the cold winter and early spring season, which is the period of the lunar month to February; peach blossoms are generally opened in March of the spring and spring, which is open when it is relatively warm.However, there are differences in the climate in some places, so the flowering time is not necessarily accurate.

5, Look at the density of petals

Although the petals of plum blossoms and peach blossoms look similar, the petals of the plum blossoms are more dense and thick than peach blossoms. The gap between the petals is smaller and the color is relatively strong. The petals of peach blossoms are relatively sparse and thin.

Symbol of plum blossoms

1. The implication of the character is high and tough

Wang Anshi's famous poem "plum blossom": "There are several plums in the corner, Ling Han is alone, knowing that it is not snow, but only a dark fragrance." In addition to praising the noble quality of the plum blossoms and the cold and cold, first in Baihua, the same is the same.It is also a praise of the author's spirit of being courageous, not afraid of hardships, and still not fearlessness in the face of hardships and suffering. plum blossoms are not afraid of cold and openly open their own toughness, self -improvement.Gumei, which has been open for thousands of years, has even enjoys his highly tough character.In the spring of Baihua, it quietly faded, and the flowers turned into spring mud in order to get over the cold winter.

2. The meaning of auspiciousness and happiness

In my country's traditional culture, plum blossoms have the meaning of welcoming the spring and good and good luck.In ancient times, people believed that plum blossoms had four virtues: the newborn stamens were Yuan, blooming as hendy, knot -.Later generations believed that the five petals of plum blossoms symbolized the five blessings, namely: happiness, happiness, longevity, smoothness, and peace.Therefore, plum blossoms often give away relatives and friends as gifts, which are both beautiful and generous.Poetry and paintings related to plum blossoms are also loved by people.

plum blossoms bloom in the months

The flowering time of plum blossoms is different due to the variety of varieties, but it is basically blooming from January to February, and the North China region will be open by about March-April.If you want to bloom around the spring Festival, you need to gradually increase the temperature to 8-12 C. Properly accept light. Occasionally spray water to the branches, and then apply thin liquid Fertilizer to make the plant more dense and strong.

plum blossom Flower maintenance

1. If you want to flow around the spring Festival, you need to increase the indoor temperature in advance and gradually increase the temperature to 8-12 C.

2. Put the plants in a better light in winter, but it cannot be directly shot in the sun, and it can be ventilated when the weather is warmer.

3. Do not rush to water during maintenance. When the Flower pot is not dry, it can spray water to the leaf surface to keep the humidity, but after the formation of the buds, the water spray or spray water around the plant.

4. Some diluted liquid Fertilizers need to be applied before the flowering period. Most of them are mainly phosphorus Fertilizer, which can accumulate nutrients for the plants, so that it can continue to bloom and keep trimming.Essence

plum blossom Flower

The flower language of plum blossoms is Lingshuang Douxue, open spring, strong, elegant, and not glory.It symbolizes Gao Jie, strong, beautiful, arrogant wind, no fear of cold, poverty, but morality.It has a strong and unyielding character. In the folk, people often regard it as a sense of auspicious symbols for passing the spring.

How to raise plum blossoms

1. Breeding environment

(1) Soil: It mainly requires loose, fertile, and well -drained soil.

(2) Watering: The soil must be kept moist during the growth period.In summer, it can be poured twice a day.spring and autumn is about once a day.winter follows the principles of dryness and pouring.No matter which season, do not accumulate water.

(3) Light: It must be provided with sufficient sunlight, otherwise the plants will become thinner and flowers less.

(4) Temperature: It is best to warm, about fifteen to 20 degrees.Low temperature will postpone its flowering.

(5) Fertilizer: When planting, you can mix the base Fertilizer in the soil.Potassium dihydrogen phosphate before flowers, with a cake Fertilizer with the flowers.In the normal growth period, Compound fertilizer, Organic fertilizer, etc. can be used.

2. Pruning

After just the pot, you need to trim it once.Especially when making bonsai, we must lay the foundation at this time.You can usually observe the state of the plant to judge whether it should be trimmed.The cross, upright, dry, too dense branches need to be cut off and cut off the short branches.In this way, it can make it look better and make it lush.

3. Method for reproduction

(1) Sowing and breeding: After the fruit matures in September, remove it, then peel off the Skin and wash it.Prepare the appropriate substrate, and wait until the end of September.

(2) Grafting and reproduction: It is mainly divided into two types: branches and buds.The root of grafting can be used for peach trees, Li tree, etc., but it is best to graft other varieties of plum trees.

Can the plum bonsai be raised indoors?

Can be kept in the room

The plum bonsai is suitable for breeding indoors. It is not poisonous and will not cause harm to the human body, but its fruit is poisonous. Do not eat it.It can release sterilizers containing aroma oil, but if someone is allergic to the home, it is best not to put it indoors.

Appropriate reason

1. There is no toxic: Lames is not toxic and does not endanger human health, but its fruit is poisonous, as long as it is not eaten by mistake, there is no problem.It is best to keep it in the place where the child is not enough, so as not to eat it by mistake.

2. Purifying the air: Lamei is a natural vacuum cleaner. It can purify indoor air, smoke, etc., can make the indoor air fresher, can also remove the toxic gas in the air, and improve the indoor air.

3. Observation: Put the plums in the interior, and watch it well. The color of the flowers is yellow. Whether it is placed in the living room or on the balcony, the home can make the home more energetic.It is only due to less light in indoor breeding, which causes the color to fade. It likes to grow in circulating air. If it is cultivated indoors, it can be opened more. If you have time, it is best to put it in a sunny place every day.

How to use sunshade shuttle curtains

1. Before the louver curtain is pulled, the leaves are tuned to 90 cents with the track, that is, the leaves and the blades are parallel.

2. When pulling the shutter curtain, hold the handle vertically and louver to pull a pull rope (the horizontal shutters are pulled all the pull rope) to pull the blade open.

3. Incorrect use methods will affect the life of the louver. When the louver's blades are not adjusted to the above angle, do not pull it;

4. Blossom curtains are suitable for air -conditioning rooms, not suitable for opening windows, do not use windows when wind is strong.

How to clean and maintain louvery curtains

1. In daily care of the shutters, people often easily ignore the cleaning of curtains. However, the curtains have been hung for a long time. Allergens such as dust and mold are easy to hide on it. Based on health considerations, curtains should be cleaned at least once every three months.In spring and summer, because the windows are often opened, it is best to wash it every two months.

2. When the soft louver curtains are cleaned, first turn off the curtains, spray an appropriate amount of water or wipes, and dry it with a rag to keep it clean and bright.As for the tope of the curtain, you can wipe it with a soft mane brush.If the curtains are dirty, use a rag dipped in some warm water -dissolved detergents to clean it, or wipe it with a little ammonia water solution.

3. Blossom curtains can usually be wiped with wet cotton cloth. Use detergents to clean it once a month. Dip a little detergent in one direction in one direction. Due to the material and spray paint, the shutter curtains are easier to fade. Be careful not to expose the sun.

4. When the rolling curtain is cleaned, close the window first, spray an appropriate amount of water, and then wipe it with a cotton cloth.If the curtains are dirty, some detergents can be dissolved with warm water, and the shampoo is dry after washing with cotton fabric; it can also be sprayed with some light wipes, which can keep the louver window for a long time.

5. Rolling curtains pull it down into plane and wipe it with cloth.The roller is hollow. You can use a thin stick, and the velvet is tied with a fluff in and constantly rotating to remove the dust.

6. The velvet curtain should be soaked in the alkaline cleaner in the medium alkaline cleaner, gently pressed it with your hands, and washed it on the oblique shelf after washing, so that the water is automatically dried to dry, and it will be as clean as new.

7. Cutting of the curtains of static velvet cloth curtains should not be soaked in water and washed or brushed.

1. What do you mean?

The sunny day is used to cover the sun. The umbrella used to cover the rainy day is called the umbrella.Generally a light -colored umbrella.Umbrellas can be used for sunny and rainy days. Umbrellas that can be covered or rainy can be covered. There is a sunscreen function, and the umbrella basically does not have the effect of anti -ultraviolet rays.Yulin umbrella cloth mainly includes a variety of fabrics such as Saling cloth, silver tape, pearl tape, T/C cloth, color weaving, fat and thin silk.Generally speaking, the price of a sun umbrella with ultraviolet protective coating umbrella surface will be higher, such as pearl adhesive tape umbrella surface.Of course, the weight of the umbrella rack must be used with lighter materials.

Second, the difference between umbrella and Parasol

The difference between the umbrella and the Parasol is mainly reflected in functionality.Although the sun umbrella is common in rainy days, it is still worse than a professional Parasol.The main function of the Parasol is sunscreen, covering ultraviolet rays, and resisting the damage caused by ultraviolet rays to the Skin. Umbrella cloth usually uses fabrics with anti -ultraviolet rays or coatings with anti -ultraviolet rays.If there are many rainy seasons in your area, the Umbrella can basically meet the needs of sunscreen, but if your area belongs to the arid area, Xiaobian suggested that you choose a professional sunscreen, so the Sun protection effect is more ideal.

Can I be used as an umbrella as an umbrella?

Yellow umbrella can be used to cover the rain, but it is best not to use the umbrella as an umbrella.Although the Parasol has a certain rainproof function, if it is used for a long time for rain, the acidic and alkaline substances in rainwater will cause the UV coating on the Parasol to aging the umbrella, which will affect the effect of Shading.When the rain is large, some of the poorly mass -covered umbrella -proof UV coating does not meet the standard. At this time, it is easy to cause the coating to be destroyed.Therefore, Xiaobian suggested that you have two umbrellas to prepare from time to time.

Matching: The appearance is very beautiful, and the assembly is very simple. DIY is autonomous.

Cost -effective: medium and high

Divided by style:

1. Flooring rack: refers to the shelf placed on the ground, mostly placed in the corner.Don't look at the wall, but the cabinet is vulnerable to moisture, and the hygiene below is not easy to clean.

2, adsorption rack: refers to the shelf adsorbed on the wall and does not contact the ground.It is convenient to take care of it, but the requirements for the wall are high, and it must be installed on the load -bearing wall. It is best to be a physical brick wall.

cleaning of the rack

1. Wipe the rack with water and dry it with a soft cotton cloth. Do not use any grinding cleaner, cloth or paper towels, and any acidic cleaning agent, bright abrasive or clearing Wipe the surface of the shelf in a sanapa or soap.

2. Because the long -term residues of chromium -plated surfaces such as various kinds of wash and shower gels are usually used to degenerate the surface of the shelf and directly affect the surface quality.Please use soft cloth at least a week clean the surface of the rack once, and it is best to use a neutral cleaner.

3. For stubbornness, surface dirt and stains that are difficult to remove, please use mild liquid cleaner, colorless glass cleaning solution, or cleaning liquid without wear. Then clean the rack with water and dry it with a soft cotton cloth.

4. You can use cotton wet cloth with toothpaste and soap, wipe it gently, and then wash it with water.

5 You can use wax oil with strong decontamination capacity, apply it on a clean white cotton cloth, and clean the entire product thoroughly. The cycle is generally 3 months. This can extend the life of the shelf life.Remember that every time you clean, you must wipe the water stains, otherwise water stain dirt may appear on the surface of the pendant.

maintenance of the rack

1. Develop the habit of opening windows and windows frequently. This will not only keep the air in the bathroom Smooth, but also help the family's health, absorb more fresh air.

2. The surface of the rack should be often wiped with soft whole cotton cloth and water to ensure bright luster. You must not use corrosive acid -alkali solutions. Try not to use detergent. clean.

3. Usually if we want to decorate, do not let the paint on the shelf, because the paint has a great corrosion effect on the plating on the surface of the rack.
