Occasionally, domestic peacocks and bamboo shoots appear to have atrophy and curling, and they no longer stretch freely. This is due to the unfavorable environmental temperature and humidity of the peacock bamboo pheasant. The high-temperature and high-humidity environment is conducive to the growth of peacock bamboo grass. If the room temperature is lower than 18°C ​​for a period of time and the humidity is lower than 60%, the above situation will occur. If no measures are taken, the leaves will soon become rotten. Even withered to death.
In addition to strengthening daily water and fertilizer management, the following measures should also be taken:
1. Spray Spray the plants and the surrounding environment three times a day in addition to the rainy weather;
2. Bagging, such as leaf atrophy is particularly serious, all the plants can be trapped in a plastic bag, in the pot mouth slightly poke some holes at 5 mm, both to maintain a certain humidity, but also appropriate ventilation, in order to facilitate recovery.
The reason why the leaves of the peacock bamboo leaf are curled and accompanied by some dead and the lower leaves are yellow is that the watering is too little and the humidity is too low. Potted bamboo shoots should always be kept moist and cannot be watered until the potted soil is dry. Peacock bamboo grass is native to tropical rain forests in South America. It requires a very moist special environment. In addition to keeping the basin soil moist, there is no phenomenon of stagnant water and roots, but also should maintain a high air humidity in the surrounding environment. To this end, it should be placed in a semi-shade place in the summer, spray water 2 to 3 times a day, and sprinkle water on the surrounding ground in order to increase the humidity and reduce the temperature and promote the robust growth of the plants.
In addition, do not pot water, can not be applied fertilizer, concentrated fertilizer, big fertilizer, otherwise it will cause root rot rotten, it will also lead to its leaves curled and yellow.
Crosswalk Led pedestrian Traffic Light
A set of Led pedestrian traffic light composed of a red pedestrian standing pattern and a green pedestrian walking pattern inside to guide pedestrians to pass.
When the green light is on, pedestrians are allowed to cross the crosswalk.
When the red light is on, pedestrians are prohibited from entering the crosswalk, but those who have already entered the crosswalk can continue to pass or stay at the center line of the road to wait.
The LED pedestrian crossing light is a new concept traffic signal light developed by our company using the most advanced LED light-emitting devices abroad. Its wick has good viewing angle, uniform brightness, chromatographic standard, low power consumption, long life, reduced degradation, high reliability and strong stability. , Good temperature resistance, wide voltage operation range. The lamp body is made of aluminum die-casting one-time die-casting, which is specially designed for LED lamps. The lamp cover is opened in V-shaped design, and it can be screwed by hand without any tools. Double sealing, ultra-thin design and light weight. It is a trendy product of today's traffic pedestrian lights, and all indicators meet or exceed the GB14887-2003 standard.
2. Appearance and structure
LED pedestrian crossing lights are composed of two parts, red people forbidden images and green people allowed to communicate. The shell adopts the lamp housing independently developed and produced by our company. The lamp housing has the following characteristics:
1. Using special pc shell, light weight, high strength, small deformation under high and low temperature conditions, and strong corrosion resistance.
2. The lamp housing is specially designed for pedestrian crossing lamps. It is small in size and beautiful in appearance. During the production process, it has undergone multiple processes such as die-casting, screening, trimming, shaping, and spraying. The surface of the finished product is smooth and clean, free of cracks, burrs, and silver wires. And other defects.
3. The color of the lamp shell is black, which is bright in color and will not fade after long-term use.
4. Appearance shape, using square shell, square shade lampshade, glass fiber reinforced plastic translucent color film with uniform brightness, wide vision and strong light transmission.
5. Airtightness. In order to maximize the dustproof and waterproof performance of the lamp housing, double sealing technology is adopted. First, a waterproof sealing ring is specially designed at the joint between the lamp cover and the lamp housing, and a special seal is used inside the signal lamp. The tray seals the LED luminous lamp sheet and the power supply with the transparent cover and the tray to maximize the sealing effect under various outdoor weather conditions. Through the above measures, the protection level of the signal lights produced by our company can reach the IP53 standard.
6. Installation, the signal lamp housing is designed with full consideration of various installation forms, and is equipped with a variety of mounting brackets, and a universal chainring is designed at both ends of the signal lamp to facilitate adjustment of the installation angle; the lamp cover adopts an open form, and Specially equipped with hand-tightening fixing screws, the lamp cover can be opened without any tools during installation and maintenance.
7. The signal lamp needs to be used outdoors for a long time. In addition to ensuring the durability of the main body of the lamp housing, our company uses stainless steel screws to fix each signal lamp assembly.
3. Lamp housing material
1. The signal lamp shell is made of aluminum die-casting, which is light in weight and good in strength. It is not easy to be deformed and aging when used outdoors for a long time.
2. The sunshade and decorative strip of the signal light are made of ultra-thin metal, which has high strength and good flexibility.
3. The color film adopts toughened glass, which has good light transmission, is not easy to get dust, and it is broken and harmless to people.
