The warming makes the sea ice ice situation hope to alleviate the drought in the north .
Since January, Liaodong Bay has been continuing to have low temperature weather. After the most serious sea ice ice situation in the past 30 years, Huanghaihai once again sounded the sea ice IV warning. Sea ice has already had a considerable impact on local fishery production and maritime transportation. . As the temperature rises, from now until February 4, Laizhou Bay sea ice will be eased, sea ice warning will also be reduced from yellow to blue, and the northern part of the Bohai Sea and the Yellow Sea will be close to normal. Liaodong Bay will continue to be released. Blue alarm. Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright In addition, due to the lack of effective precipitation for a long time, the drought in many provinces and regions in the north has not improved. The drought in Shandong and Hebei has caused local residents to drink water. Beijing has also updated the latest snow record in 60 years. In the coming week, North China and Huanghuai will be dominated by warming, and there will be no obvious precipitation, and the drought will continue to develop. Linyi Fertilizer Network Copyright
Experts suggest that: in the arid regions such as North China and Huanghuai, measures such as applying organic fertilizer and covering straw can be used to protect the mites from rising temperatures and delays. In addition, “Lichun†is approaching, and the northern winter wheat area should be changed according to the weather. Timely buckwheat, cultivating and fertilizing to increase the temperature and ensure the growth of winter wheat, and promote the growth of winter wheat in a timely manner. The dry area in the southern part of Huanghuai should be timely and timely use small water and fine irrigation in the afternoon to promote wheat seedling tillering. Linyi Fertilizer Network Copyright

Sectional Door Accessories: motor 220V-380V, control box, spring break device, cable break device , aluminum alloy rope pulley, enhanced shaft bracket, air bag system, duplex enhanced guide wheel bracket.
Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.
Rolling code remote control with max. 20 pcs hand transmitters.
The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.
