Recently, the temperature in Tianjin is obviously higher than normal, and there is a snowfall at the end of the year. The snowfall is obviously more than normal, and the sunshine conditions are biased. The snowfall eased the drought in the farmland and was very beneficial to the winter wheat that was about to return to the green. The snowfall was small and had little effect on the agricultural production of the facility.
At present, winter wheat in Tianjin is in the wintering period, the soil has not been thawed, and the early drought has little effect on winter wheat. The precipitation process at the end of this decade has become an effective supplement to the wheat field, which is generally beneficial to the return of winter wheat. The average temperature around the area was higher than normal, and there was no extreme low temperature that threatened the agricultural production of the facility. A snowfall occurred in the first ten days, but it did not adversely affect the agricultural production of the facility. The sunshine conditions in this period were slightly worse, and the facility agriculture could still be met. The need for production, in general, meteorological conditions are beneficial to facility agricultural production.
On January 31, the city's main agriculture-related county meteorological bureau conducted a comprehensive farmland public opinion survey. The results showed that the dry soil thickness of the wheat field was thinner than that of spring sowing, and the dry soil thickness of the wheat field was 3-7 cm (3 to 4 per year). Cm), winter irrigation wheat field is normal, a few winter wheat fields dry soil thickness is deeper than the tiller section, but because the current frozen layer thickness is about 50 cm, the tillage layer is still frozen, there is no loss of soil moisture, so the wheat growth is still No substantial impact is caused. If there is no precipitation in the later stage, the temperature will rise and the frozen soil will melt. The surface water will be infiltrated rapidly. At that time, it may affect the normal growth of wheat. The thickness of dry soil in spring is 4-10 cm.
