The growth of vegetables must pay attention to the cold

In the process of temperature rise in the spring, due to the influence of cold air intrusion, the temperature dropped suddenly and there was a large drop in temperature and quenching temperature. The cooling rate was 5-10°C, and the temperature dropped to 5°C or even below 0°C. ".

Early spring vegetables are mainly grown in facilities and protected areas, and are generally planted with solanaceous, melon, beans, and green leafy vegetables. As the cooling rate is large and fast, the seedlings are difficult to adapt to, and the longer the duration, the heavier the damage. The short-term cold wave damages the above-ground part of the vegetables, and the cold wave, which lasted for a long time, damages the underground part. In severe cases, it will cause frost damage, fruiting and fruit falling, and even dead seedlings; at the same time, it will also make some invasive diseases prone and popular. In the general greenhouse, the damage is heavier, and the small and medium sheds are secondary; the vegetables and vegetables are heavier, the fruit and vegetables are heavier than the leaf vegetables; the adult plants are heavier than the seedlings, and the flowering results are the heaviest. In view of the damage characteristics and the law of occurrence of late spring, vegetable farmers should generally adopt the following production strategies:

1, deep trenches. Dig out the cold ditch and repair the protection facilities. The stilts should be 20 to 25 centimeters high. The sorghum face should be 120 centimeters wide (including the ditch). A narrow ditch with a width of 15 to 20 centimeters and a depth of 30 centimeters should be dug around the shed.

2, fertilizer control water. The fertilizer and water should be well controlled, and the seedlings should be cultivated in a timely manner to cultivate strong seedlings and spray anti-cold antifreeze.

3. Pay attention to weather changes and strengthen management. Strengthen weather forecasting, grasp weather dynamics, and strengthen field management.

4, to strengthen insulation. If it is a continuous rainy weather that leads to cooling, first of all we should strengthen the insulation, minimize heat loss and maintain the temperature. Can be covered with grasshoppers and double membranes.

5, to take measures to fill light temperature. The low temperature caused by the short-term cold wave is mainly due to the lack of light and heat. Therefore, the outside temperature is very low, the sun is not enough, only relying on insulation is not enough, we must take measures to make up for the need for vegetable growth. General requirements of the temperature can not be lower than 5 °C, short-term temperature compensation measures are mainly fire, brazier temperature, electric heat, etc., in addition to additional measures can be taken, such as lights fill light.

6, strengthen pest control. According to the occurrence rules and control characteristics of various diseases, the comprehensive prevention and control principle of “prevention from prevention and treatment from treatment” is adopted in targeted manner. It is advisable to spray dry smoke powder with fumigant on the drug for preventing disease, and reduce or eliminate the use of liquid. Pharmaceutics, combined with the application of cooling and cooling to improve efficacy.

7, stop watering. In continuous rainy weather, watering should be stopped, intensive cultivation should be stopped, air release should be stopped, and old crops should be covered earlier, and fruits should be preserved.

8, timely sowing of cold-resistant vegetables. After the occurrence of disasters, timely remedial measures should be taken. For those fields that have already been damaged, they must pay no attention to supplementing the seedlings or rush to broadcast a batch of vegetables with a short period of hardiness and cold tolerance, and quickly organize production and self-rescue. The varieties that are suitable for sowing are leeks, April cabbage, and April white radish.
