In midwinter, in January, there is frost and snow, and there is often freezing, with the lowest temperature being around -10℃.

How to arrange farming activities during Xiaohan?Farming:At this time of year, we must continue to focus on the cultivation of spring flower crops, do a good job in frost and moisture prevention, and strive for a good harvest of spring flowers. It is necessary to prevent the accumulation of snow and freezing rain from breaking the bamboo forests and fruit trees. There are many fogs and strong winds in winter, so special attention should be paid to safety during fishing and breeding operations at sea or in rivers and lakes. vegetable: ⒈ Timely sowing and scientific management. Watermelon, zucchini and cucumber in medium and small sheds should be grown in nutrient pots or blocks in winter sheds or sunny beds around the Lesser Cold. For winter crops with weaker growth, such as cucumbers, tomatoes, hot (sweet) peppers, top dressing should be combined with watering. ⒉Disease prevention and control. Due to frequent rainy, foggy weather and high humidity in the greenhouse, it is easy to induce gray mold, leaf ice, blight, downy mildew, powdery mildew and other diseases of crops. For prevention and control, smoke or dust agents should be used, and pesticides should be concentrated and used alternately to effectively improve the prevention and control effect. |
