1. How to use Solar lamps

According to the principle of Solar lamps, Solar lamps are powered on during the day and light at night.The specific Solar Lamp working principle is simple. For Solar cells made of photocopyral effect principle, Solar panels during the day receive Solar radiation energy and convert them into electrical energy output. The charging controller is stored in the battery.The left and right, the voltage of the opening of the Solar cell board is about 4.5V. The charging controller detects the voltage value after the voltage value is detected, and the battery discharges the lamp head.After the battery is discharged for 8.5h, the charging and discharge control action is over, and the battery discharge is over.The main function of the charging controller is to protect the battery.

2. How to install Solar lamps

So how to install Solar lights by yourself?The method of installing Solar lamps is very simple. Just choose the right position and install it directly. The specific steps are as follows:

1. First choose Solar silicon boards.Select the size of the Solar panel according to the area or brightness requirements.

2. Then configure Solar lamps.Generally, it is better to choose LED lights. It uses low voltage, small current, and good light emitting effect.Compared with energy saving.It is recommended to choose a Solar Lamp with a special battery.

3. In terms of installation, the Solar panel is installed outdoors, and the sunlight should be received.The time to install the sunlight also determines the effect of the Lights.

4. When installing Solar panels, pay attention to waterproof, and try to install it at a high place, so that rainwater should not be soaked.

5. Share a small tip here is to place a thin transparent ordinary glass on the Solar board.This prevents the rain from getting wet directly and can effectively block the sun.Extend the service life of Solar panels.

1. Is the lounge chair not good about the waist?

Is the lounge be good for the waist?Most lounge chairs are mainly composed of three parts: lounge chairs, back chairs back, and lounge chairs support parts. The shape is based on simple geometric shapes.The human spine is in the center of the axis, and the physiological bending of the neck, chest, and waist section is physiological.If the body design of the ergonomic engineering, its arc should be designed in line with the physiological bending of the body's spine. This type of design is just the right lounge chair. When people lie down, they feel comfortable, and they can achieve the purpose of relaxing the body.

Under normal circumstances, there are about two habits of people sleeping chairs: one is to lie down for 30 ~ 40 minutes each time, lying 1 or 2 times a day, forming a living habit and lasting for many years; the other situation isThe habit of lounge chairs, and once sleeping chairs, I ca nt lie down for a long time. It lasts for several hours or even overnight to dawn. From a medical perspective, the previous habit is more reasonable.If the posture is maintained for too long, there will be adverse consequences, such as joint stiffness, muscle spasm, limb numbness, and deep venous thrombosis.

2. Does sleeping chair affect the lumbar spine?

Sleeping in a lounge chair for a long time is not good for the body. There is no good posture to sleep will affect the quality of sleep. There is also a small place where folding bamboo lounge chairs turn over and will restrain the body.It is not good, and pay more attention to physical exercise.

It should be reminded that people with lumbar back diseases, such as lumbar disc herniation, spinal stenosis, spinal body unstable, spinal malformations, etc. It is recommended to avoid sleeping chairs made of soft materials into lying chairs, because most patients with low back and leg pain exist existingThe changes in spinal physiological bending, such as the decrease in the anterior lumbar vertebrae and the degenerative side bending, the lounge chairs made of soft materials can increase these changes, resulting in changes in the spinal canal volume, causing lumbar disc herniation, exacerbation of spinal stenosis, forming a pair of spinal cordAnd nerve, vascular card pressure and stimulation, which causes low back pain, bilateral lower limbs, and symptoms such as weakness, sphincter relaxation, two stool disorders, or mild paralysis may occur in severe cases.In addition, it is best to lie down (lying on his back) to avoid side and prone, so as to avoid discomfort caused by muscle spasm, soft Skin tissue injury, and nerve card pressure.

How to grow tomato seeds to grow tomato seeds for a few days to germinate

How to grow tomato seeds

The small tomato seeds that have been dried on the paper will be exposed to the sun for a day before planting (the germs and viruses are eliminated, and the germination rate is increased), and then the seeds that have been dumped into pieces are scattered into pellets.

This is the key step of tomato seeds that cannot be omitted.

Turn the rake flat and the sun, rich in humus, fertile Fertilizer and loose seedlings "beds", and then lay a layer (20 mm thickness) on it.

First spray the water in the seedling bed, then sprinkle the small tomato seeds evenly on the seedbed, and then support the arc -shaped bamboo skeleton to cover the plastic film, and use stones and soil pressure to be surrounded by the surrounding area (moisturizing and insulation)Essence

How many days do tomato seeds germinate?After 3-5 days (temperature factors), the seeds will sprout. When the embryo leaves grow, they should open a plastic film on the morning of the day to change the fresh air for them.

When the true leaves appear, they should carefully spray the light feces urine and Fertilizer with a romance pot.

When the soil in the cultivation bed is dehydrated, it is necessary to supplement it with a barrel in time.

In this way, you can transplant it in the planting field without a month of operation (use a flat shovel to cut one inch of thickly cultivated soil to take the seedlings, and the soil transplants will return early).

Many people growing tomatoes are not very good. They waste a lot of manpower and material resources. At this time, you need to learn more about tomato cultivation technology. Speaking of tomato cultivation technology, Xiaobian is the expert in this area.Let me introduce the tomato cultivation technology.

Tomato cultivation technology

1. For environmental conditions

Temperature: Tomatoes have strong adaptability to temperature and can grow at 10-30 C temperature.There are certain differences in temperature requirements at different fertility stages.The optimal temperature of the seed germination is 25-30 C, the minimum temperature of the germination is 12 C, and the temperature of the seedling period is suitable during the day.

Among the tomato cultivation technology, temperature is the most critical point.

2. Main cultivation technology

1. Cultivation season: Export processing tomatoes are mostly for open field cultivation.Tomato is a vegetable crops that are not resistant to high temperature and are afraid of frosting, and are suitable for planting during a frost -free period at an average temperature of 15 C or more daily.

2. my country's region is vast, and the north -south climate is very different. Lulba planting tomatoes are generally in South China such as Guangdong, Guangxi, Fujian and other places. There are no frost throughout the year.

3. In summer, high temperatures are more rainy, and typhoons often have typhoons. Only autumn and winter weather is fine, sufficient light, less rain, warm climate, most suitable for planting, generally sowing from August to October, transplanting in September to October, starting in mid-November, starting in mid-November.Receive until late February of the following year.In the middle and lower reaches of the Yangtze River, the frost -free period is very long and can carry two stubbles a year.spring stubble generally sowed seedlings from November to December, planted in mid-to-late March of the following year, harvested in mid-to-late May, and seedlings were pulled in mid-to-late July;Harvest in early October, and in late November.

1. How to classify football shoes

football shoes are shoes to play football. There are many types. According to different classification methods, they can be divided into the following categories:

1. Classified by fabric

football shoes can be divided into kangaroo leather football shoes, kraft football shoes, artificial fiber football shoes, fabric football shoes, artificial leather football shoes, artificial PU football shoes, including the performance of the fabrics, artificial fiber football shoes, artificial leather football shoes.The price is more expensive.

2. Classified by the material of the shoe

football shoes can be divided into four types: TPU, nylon, carbon fiber, and rubber. The TPU sole has the characteristics of toughness, wear resistance, transparency, and low cost, but the overall is relatively heavy.nylon soles are lighter and stronger, and the rebound is stronger, but the toughness is insufficient and the cost is high.carbon fiber soles are very light quality and high elasticity, but the cost is very high, and the requirements for the use of the site are also extremely high.The rubber soles have a certain cushioning performance, but the limit is large.

3. Classified by the material of the shoe nails

football shoes can be divided into three types: steel nails, rubber nails, and broken nails according to the nails. Steel nails are generally worn by professional players. If it is rainy, they also wear extended steel nails. The non -slip performance is better.Both the gum kick kick and the fake grass Skin are suitable, and it is not easy to hurt people, and as long as it does not rain, the non -slip performance is also very good.Broken nails are also made of rubber, but the small rubber nails are evenly distributed on the soles.Mainly indoor football, hard venues, such as rubber venues, cement venues.

2. Types and characteristics of football shoes nails

In the classification of football shoes, the common classification method is to classify according to the nails. The characteristics of football shoes of different sneakers are also different:

1. Steel nail

Steel football shoes are also called SG, which is suitable for soft or very soft grasslands on the surface. The nails are relatively long and can be freely loaded and unloaded. Generally, football shoes that use this nail on this shoe.

2, long nail

Long -nail football shoes are also called FG, which is suitable for relatively hard natural grasslands on the surface. Its nail length is the longest. At present, most professional players wear FG shoe nails during the game.

3, short nail

Short -nail football shoes are also called HG, which is suitable for hard surface artificial grassland.Short -nail football shoes are nails made of synthetic materials. The layout of the soles of the shoe is dense. The shape is similar to the long nail football shoes, but the material is poor.

4. Human grass special nails

Human grass football shoes are also called AG. This kind of shoe nails are shorter than short nail football shoes, generally only about 1 cm, and the rubber used is soft than long nail football shoes and short nails.The number is also more than the above two categories. It is suitable for artificial lawns with rubber particles and fine sandy thickness than 1 cm.

5. Broken nails

Broken nail football shoes are also called TF, which is suitable for various artificial courts. It has strong adaptability and slow startup, but the pressure on the ankle and knee joint is the least.This kind of football shoes can not only conduct daily training, but also play the positive game.

6. Rubber flat bottom

Rubber flat football shoes are also called IC or IN, which are suitable for the indoor football fields that have been polished and Outdoor artificial grass venues with very poor quality.The wooden floor of the indoor football field is very Smooth. If you wear a sneakers with nails, when you turn around, the strength will be concentrated on a few nails under your feet.Wear rubber flat shoes.
