In the first half of this month, wheat in Hubei Province was in the tillering stage, and rapeseed was in the seedling stage. In the first half of the year, the temperature was high and the light was sufficient. It was beneficial to the growth of oil wheat seedlings, which led to the emergence of a small number of prosperous periods. Although there was a strong wind cooling process in the middle of the first half of the year, the duration was short and there was no obvious disadvantage to agricultural production; There is no precipitation in the Ministry, most of the soil is dry, and some have drought-like outcrops. The rapeseed seedlings are complex, and the soil dryness has certain effects on fertilization, which also leads to weak seedlings and does not reach the standard of strong seedlings before winter.
It is expected that in the early period of mid- December , due to the eastward movement of the west wind trough and the strong cold air on the ground, there is a rain and snow weather in Hubei Province, accompanied by obvious wind and cooling weather. Most of the rains are slightly more than normal in the same period of the year, 10 to 15 mm in the north and 15 to 20 mm in the south . The average temperature is close to normal in the same period of the year, 5 to 7 °C in most areas , and the extreme minimum temperature in the north is -4 to -2 °C. - 2 to 0 °C.
According to the later weather trends and crop development process, the farming proposal:
1. In the early part of this month, there is a rain and snow process, and the vegetable greenhouses are well protected against freezing and warming.
2. Strengthen the field management of wheat and rapeseed seedlings, and timely apply seedlings to the fields due to drought and weak seedlings.
3. For the wheat that has grown too prosperous and may be jointed before the year, it is necessary to suppress or adopt deep-seated tillage and strengthen the body; for the rapeseed that may be convulsions before the year, spray paclobutrazol should be sprayed to prevent vigorous growth.
