On the 10th, it was learned from the related meeting in Yantai that starting from January 2013, the county and the city as the units, in accordance with the requirements of pollution-free technical standards, prohibit the use of highly toxic and high-risk pesticides. At the same time, it will also comprehensively promote the use of solar insecticidal lamps. It is understood that the application of insecticidal lamps has been started in Fuping and Penglai. Among them, Penglai City has invested more than 600 solar insecticidal lamps, and each lamp can “cover†30 acres of orchards. Chen Jianzhuang, head of the Industrialization Section of the Agricultural Bureau of Penglai City, said that moths and insects all have phototaxis. The insecticidal lamp absorbs sunlight during the day and the insecticidal lamp emits light at night. It can trap and kill fruit tree pests and reduce or even eliminate the use of pesticides. It is believed that this measure is conducive to ecological and environmental protection and has caused strong repercussions throughout the country.
A floor drain is a plumbing fixture that is installed in the floor of a structure, mainly designed to remove any standing water near it. They are usually round, but can also be square or rectangular. They usually range from 2 to 12 inches (5.1 to 30.5 cm); most are 4 inches (10 cm) in diameter. They have gratings that are made of metal or plastic. The floor around the drain is also sloped to allow the water to flow to the drain. Many residential basements have one or more floor drains, usually near a water heater or washer/dryer. Floor drains can also be found in commercial basements, restrooms, kitchens, refrigerator areas, locker/shower rooms, laundry facilities, and near swimming pools, among other places.
