According to the comprehensive analysis of the prediction results of the soil drought and flood prediction model, it is estimated that by July 15th, 2012, there will be drought patterns in the 0~30cm soil layers of individual counties (cities) in Heilongjiang Province, distributed in the Songnen Plain and the Sanjiang Plain, and in the northern part of the Sanjiang Plain. Some counties (cities) such as Nenjiang, Keshan, Anda have wet soil, and other agricultural areas have normal soil moisture.
According to the results of soil moisture observation on July 8 and the precipitation analysis on July 9, as of July 10, 2012, some villages and cities in Qiqihar, some counties and cities in Harbin, west of Jixi and Dulbert in the 0~30 cm soil layer of the agricultural area , Xunke, Lanxi, Jidong, Tieli, Qing'an, Huachuan, Jixian, Suibin, Shuangyashan City, Qitaihe City, Mudanjiang City and other counties and cities have drought; Nenjiang, Keshan, Bei'an, The Suifenhe soil is wet.
It is predicted that in the next three days, there will be more precipitation in Heilongjiang Province, moderate rain in the south and east, and most of the other areas are mainly showers or thunderstorms, and the temperature has dropped. Comprehensive prediction of comprehensive soil drought prediction model and recent weather conditions, from July 13-15, 2012, there will be drought in the 0~30cm soil layer of individual counties (cities) in Songnen Plain and Sanjiang Plain of Heilongjiang Province, north of Sanjiang Plain and Some counties (cities) such as Nenjiang, Keshan, Anda have wet soil, and other agricultural areas have normal soil moisture.

The rice area should pay attention to temperature changes, strengthen water layer management, and ensure normal rice growth.
slitting Flat Bar can be as finished steel, also can be as raw material of welded pipe and thin plate used for laminated sheet. Flat as timber can be used to make iron hoop, tools and mechanical parts, building used for real frame structure, escalator
Compared with the traditional steel, slitting flat steel has the following advantages:
1, the product surface smooth
The process of secondary use of high pressure water descaling process to ensure that the steel surface smooth.
2, product specifications special
Thickness of 8 ~ 45mm, width 150-600mm, length 5-15m, and the product specifications file range is relatively close, to meet the needs of users, instead of the use of the board, without cutting, you can directly welding.
3, both sides of the vertical, clear water chestnut
Finishing in the two rolling, to ensure that both sides of the vertical degree is good, angle clear, the edge of the surface quality is good.
