Last week (November 29 to December 5, 2010), the average temperature in most parts of the country was high, and precipitation in some areas of Central China was less, and meteorological drought continued in some areas. 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 are relatively large. The average temperature in Huazhong is about 1 degree Celsius lower than normal.
Agricultural and agricultural conditions that need attention in Central China this week:
Last week, there was no precipitation in some parts of Central China, the temperature was high, the wind was windy, and the meteorological drought was still developing. It is predicted that there will be no obvious rain (snow) weather in most of the wheat areas before the weekend, and the meteorological drought will continue. Therefore, scientific field management should be carried out 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 low temperature freezing damage;
The main crop development period in Central China this week:
Winter wheat: seedling stage, partial tillering;
Rape: seedling stage;
Deep well Plate is an ideal product for sample storage, we have many types of 96 Deep Well Plate, such as 0.5ml elution plate, 1.2ml square well V bottom plate, 2.0ml round well U botttom plate for Hamilton and Nunc machines, 2.2ml square well V bottom and 2.2ml square well U bottom.
