1. How bright the street lights in the residential area are suitable

The brightness adjustment of the community street lights is a big problem, mainly because the street lights are too bright, which will cause residents on low floors to feel dazzling, and the light pollution is more serious. If the street lights are too dark, it will affect the night travel of the community.In the accident, the thief is easy to make a crime, so how much is the street lights in the residential area?

In fact, my country has clearly stipulated the brightness standards for street lights in residential areas. According to the "Urban Road lighting design Standards", the road of community roads should be about 20-30LX, that is, people can be 5 See clearly within 10 meters.The lack of lighting in some communities is mainly due to the reduction of lighting requirements in order to save costs and electricity.In addition, when designing the street lighting, the support of the branch road is narrow and distributed between the residential buildings. The uniformity of street light lighting needs to be considered. Generally, it is recommended to use unilateral layout lamps to light up lighting.

2. Requirements for the installation specifications of community street lights

1. Light type

The width of the community roads is generally 3-5 meters. Considering the illumination factors and convenient maintenance of the community. Generally, the courtyard Lights between 2.5 and 4 meters in the community are used to light up.Personnel can quickly repair.In addition, courtyard Lights can pursue the beauty of the overall lamp according to the architectural style and environmental atmosphere of the community and beautify the community.

In addition, the shape of the street lights should also be simple and Smooth, and there should not be too many decorations. If there are large -area lawns and short flowers in the community, you can also consider using some lawn Lights.

2. Light source

Unlike the high -pressure sodium lamp commonly used in main road lighting, the main light sources used in community lighting are metal halide lamps. Gold halogen lamps with cold -colored light can create a sense of quietness, which can make the entire community feel layered and create low -floor residents for low -floors residents.A soft Outdoor environment, avoiding light pollution at night at night.

Community lighting also needs to consider vehicle factors, but the vehicles in the community are not like the vehicles on the main road, generally slow, so the pursuit of uniformity in brightness is not high.The brightness of the lamp area is relatively high, while the brightness in other places is low.

3. Light position arrangement

Due to the complexity of the roads in the community, there are many intersections, and there are many splits, the lighting of the community should have a good visual orientation, and unilaterally arrange it;Side layout.

In addition, when conducting community lighting design, we should pay attention to avoiding the impact of Outdoor lighting on the indoor environment of the residents. The lamp position should not be too close to the balcony and windows, and it should be arranged in the green Belt on the side of the road.

4. Power distribution settings

For residential communities with a small area, the lighting distribution box is generally located in the center of the community and sent electricity to the surrounding area. It is a central radiation type. The lines are not long, but there are more bits.Multiple ways to send electricity can not only solve the loss of voltage reduction, but also facilitate future pipeline maintenance, but the cost is slightly higher.

After the street light supply power distribution point is connected to the control cable, it can be controlled by the street light control network. It can also be equipped with control devices such as wireless Sanyao.

Emerging agricultural machinery equipment, replacing traditional manual operations, has the characteristics of high efficiency and convenient carriers to get the love of farmers' brothers!

definition

The seeder refers to the planting machine with crops and seeds as the object. The seeder has the characteristics of uniform seeding, consistent depth, stable lines, good soil covering, saving seeds, and high work efficiency.

Pay attention to the main points

Pay attention to the following points to master the following points:

Before entering the field, clean up the debris in the seed box and the entanglement and soil on the ditch to ensure a good condition. The transmission and rotation parts of the tractor and the seeder will be injected with lubricating oil according to the requirements of the instructions, especially in particular, especiallyBefore each job, pay attention to the lubrication and tension of the transmission chain, and the tightening of the bolt on the seeder;

The rack cannot be tilted. After the seeding machine is connected to the tractor, it must not be tilted. When working, the front and back of the rack should be in a horizontal state;

To do a good job of various adjustments, in accordance with the provisions and agronomy requirements of the instruction manual, the seeding amount, the spacing of the ditch, and the depth adjustment of the ditch to the soil suppression wheels are appropriate;

Pay attention to adding the seeds and add the seeds of the seed box to achieve no small, , and miscellaneous to ensure the effectiveness of the seeds; secondly, the amount of seed boxes should be added to the entrance to the breeding box to ensure the Smooth seeds smoothing the Smooth breeding boxesItems

In order to ensure the sowing quality of the seeder, before the large -scale sowing, you must insist on the trial broadcast for 20 meters to observe the work of the seeder.Ask agricultural technicians, local farmers and other test consultations to confirm the local agronomy requirements, and then plant large -scale seeding;

Pay attention to the uniform speed line, and the agricultural machine handles choose the operation to walk the route. It should be convenient for the addition and mechanical entry and exit. When sowing, pay attention to the straight line forward.

In order to prevent the ditch from blocking, the lifting of the seeding machine should be operated during the travel, and the seeding machine should be lifted when retreating or turning;

Predse the ground first, first sow the ground to avoid rolling the ground, causing deep broadcasts; regular observation, often observing the work conditions of the gaunting device, ditch, coverage, and transmission mechanism during sowing., Covering grass and seeds are not strictly covered, and timely eliminate it.

Adjusting, repairing, lubricating or cleaning up grass, etc., must be carried out after parking;

When the protection of the machine, when the seeding machine is working, it is strictly forbidden to retreat or turn sharply.

Pay attention to the seed box, the seeds in the seed box during operation must not be less than 1/5 of the seed box volume;

When transporting or transferring the block, there must be no seeds in the seed box, let alone other heavy objects.

history

The first seeder was made in Greece in 1636.In 1830, the Russians installed the seedlings on the livestock plow to make a plow broadcasting machine.After 1860, Britain, the United States and other countries began to produce large amounts of animal grain sowers after 1860.After the 20th century, traction and suspension grain seeders appeared one after another, as well as the seedlings using forceful seedlings.In 1958, the first centrifugal seeder appeared in Norway, and various precision seeders gradually developed after the 1950s.

The seeder was introduced in the 20th century, and in the 1960s, it was successfully developed a variety of models such as the suspension grain seeding device, centrifugal seeder, universal rack seeder, and air -suction seeder.Formulator.By the 1970s, two series of sowing plowing machines and grain joint seeding device had been formed and put into production.Various broadcasting machines and acupoints for grains, farming crops, pastures, and vegetables have been promoted and used.At the same time, a variety of precision seeders were successfully developed.

maintenance method

After the seeding season is over, the dust on the seeds is completely cleaned, and the seeds and Fertilizers in the seed box are cleaned.The friction parts and transmission devices of the seeding machine are cleaned, and lubricate, such as the transmission chain, and apply the rust -proof agent after drying.Check the tightness of the connector. If there is a loose, it should be tightened in time.

The exterior and seeding shaft of the gear transmission device of the seeder should be coated to lubricate oil.The springs should be adjusted to a free state of freedom.The sowing machine should be placed in a dry and ventilated warehouse. If it is kept in open -air, the wooden seed box must be covered, and the seeding machine should be matched in two wheels.The frame should also be padded to prevent deformation.The preparation, parts and tools should be stored in the library. After the seeding machine is stored for a long time, it should be maintained early before sowing in the next season.

The metal transmission Tube of the seeder should be removed. Do not deform in the indoor control. Relax the telescopic springs of the ditch.place.The disc truncapus must be decomposed. After cleaning the diesel, reassemble and get the oil. The surface of the inside and outside of the disc is coated with waste oil. It is placed in a dry and covered room.Get up with a wooden board.

Trail garden lampdesign

In the design of the trail garden light, pay attention to the following problems:

1 , Most of the Lantern Lights of the Trails exist in the form of man -shot lightDifferent from the light -shot light and direct light, it will not produce too much shadow, making the color brighter and darker.However, an important problem that the lamp in the form of light -shot light needs to be solved is that the surface temperature of the luminous body is too high.Judging from the popular trail garden Lights on the market, few products can solve such problems.

2 Calculation of elevation angle and shoulder distance.Calculation of elevation angle and shoulder distanceIt can achieve a good balance between functional and landscape effects. For example, if the design of the elevation angle is considered, it can better reflect the role of the landscape and meet the needs of people in terms of function.

Silver fingers, a plant species under the family of cactus, and the palating ball.Fairy balls, Xiyang, white soft thorns.Don't be afraid of being broken. After the surface of the soil is dry, water the yin.The Yangtze River Basin should pay attention to cold prevention and warmth in winter. It can be placed indoors. The room temperature is not less than 5 degrees. It is suitable for planting sandy soil.

Habit

The silver fingers are full of sunlight, and the plant should be placed in the sunny area in the spring of the autumn to spring, which is warm and the growing temperature is 15-22 .Do not pour it, water it thoroughly. "Keep it slightly dry. After the soil surface is dry, watering is watered.

sunshine:Silver fingers Xiyang, don't be afraid of being broken.But afraid of continuous humid weather, afraid of cold, frostbite below zero, so it is better to put in the room in winter.

Fertilization:Fertilization is carried out in spring and autumn. It is fertilized once in about half a year. It is best to use long -term Fertilizers, such as potassium nitrate.

flowering:Occasionally, it will give you a little surprise.Because its flowering period is generally in the morning or evening, it lasts for a few hours to a day.

temperature:The silver fingers are warm, and the growth temperature is 15-22 degrees Celsius.Pay attention to cold and keep warm during overwintering.

Basin:Basin should be turned over every 1-2 years.Fer fertile, good drainage sandy soil.

Breeding method

1. Subtraction

This method is relatively simple, and it is suitable for newcomers. Each pot of plants will have a growth point. Cut it with a sharp knife and re -plant it into the appropriate soil. After the multiple sub -plants grow, it grows to its growing up to its growing up to its growing up.After a certain size, you can plant it.Many friends do not go down because of the growth of friends when they grow up.However, if the novices cannot operate this method, then continue to look down.

2,Cuttings

precautions for silver finger breeding

1. You can use a small pot with a small pot.Similar to many kinds of flower buddies, it is slower and slower than the golden fingers, so it does not require large Flower pots.You can use holes with more breathable cartoon Flower pots.

2,The soil with silver fingers does not require vermiculite, or perlite or something.Ordinary garden soil, just add some rough sand particles.It cannot be soil that is too sticky and easy to cut.If you apply Fertilizer, you don't need to fertilize it frequently, once or twice a year.

3. In summer, the silver fingers do not need to water too much. Be careful not to pour through when watering.Give it shade at high temperature.In fact, the hardest time for silver fingers is summer.Just spend summer.Usually watering should be poured separately for many days.It is more resistant to drought.

4,In winter, the silver fingers can be obtained from the balcony outdoors. It is best to keep the indoor temperature above 5 degrees. Do not water it at this time.It is easy to hang up as soon as watering.As long as you spend the cold winter, spring will grow well.
