The LED Linear Trunking System have an integrated cable-free system called trunking, which is pre-wired in the factory. The trunking can be seamlessly spliced, and the installation of the trunking does not require additional wiring and purchase additional materials. Therefore, it can greatly shorten the construction period, reduce installation costs, labor costs, and auxiliary materials costs.
The 7 Wire trunking linear lights can achieve the following functions:
(1)L,N,E (Basic Lighting)+ Sensor/Dimming + Built-in Battery Emergency
(2)L1,L2,L3,N,E (Basic Lighting)+ Sensor/Dimming
(3)L1,L2,N,E (Basic Lighting)+ Sensor/Dimming+ Built-in Battery Emergency

Rice planthoppers and rice leaf roller are two major pests that harm China's rice production. These two pests can move long distances, so they are called "two-shift" pests. In spring and summer, as the subtropical high is continuously strengthened and moved northward and westward, the range of southwesterly airflow gradually expands to the north, and the main rainfall zone moves northward. The insect source of rice planthopper and rice leaf roller is from south to north. The migration, with the sinking airflow or precipitation, has jeopardized the Jiangnan, South China early rice and the Yangtze River basin and its north season rice; the subtropical high pressure weakened southward in September-October, the continental high pressure moved southward, rice planthopper and rice vertical The leaf-rolling locust migrated from north to south with the northeast airflow, again damaging the late rice in Jiangnan and South China. In the landing zone, the meteorological conditions of moderate temperature, overcast and high humidity are conducive to the reproduction and growth of rice planthopper.
From May to June 2010, the process of heavy precipitation in southern China was frequent. The precipitation in the south of Jiangnan, South China and Southwest China was generally above 300 mm, including 500-800 mm in southern Zhejiang, Jiangxi, Hunan, Fujian, Guangdong and Guangxi. In the central and eastern Jiangxi, northwestern Fujian, and northwestern Guangdong, there are 800-1000 mm; the rainfall in the south-central and south-eastern parts of the Yangtze River is more than 30% more than normal in the same period of the year, including southwestern Jiangxi, northeastern Fujian, and northern Guangdong. Up to 1 time. With many heavy precipitation processes and cloudy and high-humidity weather conditions, rice planthoppers and rice leaf roller are more severe in the south and early rice areas of southern China from May to July. According to the statistics of the Ministry of Agriculture, as of July 15th, rice planthoppers occurred in the south of China, Jiangnan and other places, 131 million acres, compared with last year, the growth period of rice increased by 15.9%, the overall weight is higher than the previous year; rice leaf roller is in southern China In the southwestern part of the country, south of the south of the Yangtze River, and the south of the south of the Yangtze River, there were 103 million mu times, which was 49.3% higher than that of the same period last year. The incidence was significantly heavier than that of the previous year.
In the middle of July, the main rain belt of China was carried northward to the Yangtze River Basin and the Huaihe River Basin to the Sichuan Basin. With the early stage of the Yangtze River and the South China, the early stage of the maturity and the northward elevation of the rain belt, the "two-shifted" pests in southern China and the south of the Yangtze River The area has stabilized and declined, and gradually entered the end; it has gradually moved northward to the southwest, the middle and lower reaches of the Yangtze River and the Jianghuai one-season rice area, and the above-mentioned areas have entered the peak period of damage. It is expected that in the next 10 days, the precipitation in the eastern part of the southwestern region, the middle and lower reaches of the Yangtze River and the first season of the Yangtze River and the Yangtze River will still be more, and the meteorological conditions will facilitate the development of the "two-shift" pests.
Since May-July this year, the occurrence of rice planthoppers and rice leaf rollers in Jiangnan and South China was more serious than last year. From September to October, the "two-shift" pests will move from north to south, again damaging Jiangnan and South China. According to the forecast of the Ministry of Agriculture, from August to October, the occurrence of rice planthoppers in the southwestern region, the middle and lower reaches of the Yangtze River, the Jianghuai one-season rice area, and the southern rice areas of southern and southern China are 4-5, which will be biased to occur; The degree of occurrence in the eastern part of the southwestern region, the middle and lower reaches of the Yangtze River and the first season of the Jianghuai region, and the late rice areas in the south of the Yangtze River and the south of the Yangtze River are 4-5, which will be biased to occur.
The Ministry of Agriculture and the China Meteorological Administration jointly reminded relevant departments to do a good job in prevention and control in a timely manner:
1. The southwestern region, the middle and lower reaches of the Yangtze River and the Jianghuai one-season rice area should closely monitor the migration and occurrence of the "two-shift" pests, pay attention to the use of fine weather, timely use of drugs or light traps to prevent and control.
2. The rice fields in the south should pay attention to improving the paddy field environment, clear weeds in time, maintain a reasonable group structure, promote the ventilation and light transmission of rice fields, and create a farmland ecological environment that is not conducive to the development of "two-shift" pests.
