Last week (November 29 to December 5, 2010), the precipitation in northern Xinjiang was 1-10 mm, and the precipitation in parts of the northern part of northern Xinjiang was 10-20 mm. Compared with the same period of the previous year, the weekly precipitation is less than 50% or more in the northwest. During this period, the average weekly temperature was 2-4 degrees Celsius higher than that of normal years, and parts of Xinjiang, Ningxia, Shaanxi and other provinces were higher than 4 degrees Celsius.
This week (December 6-12, 2010), cold air activities are frequent, the forces are strong, and the scope of influence is wide. The temperature fluctuations in most areas vary greatly; some parts of Xinjiang will have snowfall weather.
Agricultural and agricultural conditions that need attention in the Northwest region this week:
The wheat area should carry out scientific field management according to the conditions of the seedlings, lyrics, and temperature (degrees). If the growth has been stopped or there is no irrigation water source, measures such as soil cultivation, repression, heat-heating fertilizer or covering can be adopted to ensure the temperature increase and avoid drought or freezing damage. In the wheat fields (especially weak seedlings) that have water source conditions and have not stopped growing, winter irrigation (especially severely dry plots) can be carried out in time when the daily average temperature drops below 5 degrees Celsius (when the night is frozen), and timely suppression after watering , paddling, increase the insulation, promote wheat rooting, tillering, to achieve strong wintering. Wang Miao should not use winter ploughing and repression to promote its rooting and inhibit the growth of its aerial parts too fast, so as to improve the ability to resist cold damage.
Facilities such as greenhouses, livestock and poultry houses, etc. should continue to be well protected against wind and snow. After snow, clean the snow on the sheds to avoid collapse, damage, cold and heat preservation caused by strong winds or snow, and ensure the facilities of vegetables and flowers. Such as strong growth, to avoid livestock and poultry, aquatic products, etc. suffered from freezing damage. After the snow, the temperature is low. In some areas, it is necessary to prevent the adverse effects of traffic caused by snow and frozen roads. The pastoral area should continue to do a good job in the reserve, transportation and livestock grazing of forage materials, the snow, dust and cooling of the transition.
The main crop development period in Northwest China this week:
Winter wheat: tillering, partially stopped growing;
Rape: seedling stage;
Mild steel, sometimes referred to as carbon steel or ordinary carbon steel, is defined as having a carbon content of no more than 2% and no other perceptible alloy elements.
This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
