January weather forecast and farming activities

　　

        In January , there were two solar terms, Xiaohan and Dahan, which was the coldest season of the year. January precipitation is expected in southern regions of our province near normal, near normal in other regions slightly less; close to the monthly average temperature, southeast of the province, in the northern part often slightly lower, near normal in other regions, monthly extreme minimum temperature province north The central region is at -10 °C and the southern region is at -7 °C. The main cold air activity process is 6 times, the time is 7 to 9 days, 11 to 13 days, 16 to 17 days, 20 to 21 days, 23 to 25 days and the end of the month, of which 7 to 9 days , 11 to 13 days, From 23 to 25 , there was light snow in most parts of the province and medium snow in the south. Soil moisture: based on current soil moisture and weather forecast for the next month, is expected to January 28, Yu soil in some areas relative humidity of 50% to 60%, slightly less soil moisture; northern Henan, Yudong, south of Henan section soil area above 90% relative humidity, the soil is wet; most of the other areas suitable soil moisture, soil relative humidity of 60% to 90%, wheat facilitate normal growth. In January , there were mainly the following farming activities:

First, cold air activities are frequent, and we must pay close attention to weather changes. Take cover, fumigation and other measures of weak resistance to cold crop before the arrival of cold air, light and strive to reduce frost damage. After cold air, it is necessary to strengthen the field management, timely topdressing and cultivating the soil to enhance the cold resistance of the crop. In areas where the soil moisture of farmland is too large, it is necessary to grasp the clearing ditch and ensure the stable growth of wintering crops. At the same time, all localities should pay attention to the thermal insulation work of facility agriculture and promote the normal growth of crops.

 

Second, it is necessary to do a good job in the cold insulation of greenhouses and greenhouses. Most greenhouses and greenhouses in our province have poor cold insulation. Especially in the recent cloudy days , vegetables may suffer from cold damage or even freezing. In this weather, temporary warming should be carried out at night. Warm or start the heating line to warm up. In addition, a light source such as a sodium lamp should be installed in the shed to fill the light, or a reflective curtain can be placed on the back wall of the shed to increase the reflected light. In winter, the number of irrigations should be minimized. If irrigation is done, irrigation should be carried out at noon on sunny days, and the amount of water should not be too large.

 

Third, the Spring Festival approaching, the recent rainfall, windy weather, high fire danger rating, around the forest and the vast rural areas to guard against the risk of forest fires and fire a variety of risks.
