China Xingnongwang reported on January 29 that during the day during the day, there is light rain in northwestern Guangxi, and cloudy weather is the main area in other regions. Some counties in the northern part of Guilin, Liuzhou and Hechi and the cold mountainous regions in the whole region are frozen; the lowest temperature is: Northern Guangxi - 1～3°C, alpine mountain area -4～-1°C, south Guangxi 4～7°C. From January 30 to February 1, the whole area is dominated by cloudy weather, in which the alpine mountains are frozen. From February 2 to 3, there was scattered rain in the northwest of Guangxi, and the rest of the area was cloudy. On the 4th of February, the whole area was cloudy. As the next week coincides with the peak season of Spring Festival travel, the localities will continue to do a good job in the safety and evacuation of transportation, and continue to do a good job of preventing cold and freezing in the economic crops and aquaculture such as vegetables and fruit trees.
Farming advice:
1. Vegetables in greenhouses: Seedlings of pepper and other eggplant vegetables in greenhouses. One must adopt electric heating and multi-layer covering measures. It is best to cover the straw insulation at night time; Second, watering is less to reduce the humidity inside the greenhouse. Third, it is necessary to prevent and control the occurrence of diseases in a timely manner. Attention should be paid to the occurrence and spread of damping-off and blight. At the same time, it is also necessary to strengthen the low-temperature exercise during the seedling period and improve the cold resistance of the seedlings. After the seedlings emerge, the seedbed should be ventilated, and gradually increase ventilation with warmer weather. The seedlings should be subjected to low-temperature exercise to improve the cold resistance of the seedlings and to adapt to outdoor low-temperature environment. Conduct a comprehensive inspection and reinforcement treatment of the existing vegetable greenhouses to clear the snow in time and avoid sheltering.
2. Fruit trees: For frozen fruit trees, regardless of the severity of freezing, they should be watered and fertilized more, and pest and disease prevention and control should be strengthened so as to promote its restoration as soon as possible. For lightly frozen fruit trees, fertilize as early as possible after soil thawing in early spring, at the same time, irrigation should also be carried out in time to promote the growth of roots and shoots. For frozen branches, light shear should be carried out when the temperature in early spring rises above lO°C. Unfreezed shoots should be kept as much as possible. For trees whose trunks are significantly frozen or drained due to freezing, dry them in time.
3, fishery: When the weather improves, clearing ponds and drying ponds should be cleared as soon as possible, and be disinfected with quicklime to remove excessive silt. After the temperature has risen, first fill the water and put appropriate amount of mixed fish species such as oysters and clams. For ponds with less dead fish phenomenon, due to long-term rainy weather and large amount of groundwater for thermal insulation, it is necessary to pay close attention to changes in water quality, keep the water fresh, and find that the water quality is acidic, and use appropriate amount of quicklime to transfer water to Quanchiposa. , adjust the acidity, the dosage is 10mg/L.
