The weather is particularly warm, what effect will it have on the garlic in the field?

A friend said that the overwintering water may not have been watered years ago, but it will turn green after 20 years. The wintering water many years ago was not so important. Some farmers say that water should be given before the soil is frozen to ensure that the seedlings can survive the winter safely. Earlier, some experts said that this warm winter is a foregone conclusion. Warm winter is not so cold for us, but it is bad for crops, and there may be drought.

Garlic We planted garlic in June+10 in 5438, and it will still be in seedling stage next spring. It takes a long time and the temperature changes greatly, from a dozen degrees to a few degrees below zero. Warm winter temperatures are likely to lead to the prosperity of garlic. During the normal wintering period, garlic seedlings are strong, with 5 leaves long and a plant height of about 25 cm, which can safely overwinter. In warm winter, some garlic grows vigorously and grows to 7 leaves before winter. When the temperature is low, it is easy to cause freezing damage. Therefore, measures should be taken to prevent freezing injury before the arrival of severe cold weather.

If the soil moisture content is good, it can wait until next year to turn green. Generally, many farmers will start watering winter water from165438+1late October+65438+mid-February to raise the ground temperature and prevent freezing injury of garlic seedlings. Now there is no ice in the daytime, the temperature is above 3℃, and the temperature is around 0℃ at night. You can also water it in winter. The soil is not particularly dry this winter, which can protect the temperature of the soil and resist freezing. However, a small amount of water should be used instead of flooding, so as to avoid excessive water and rotten roots after late snow. In order to prevent freezing injury, antifreeze can also be sprayed once, and potassium dihydrogen phosphate and amino acid foliar fertilizer containing rape seed can be added to make garlic stems and leaves more robust, enhance their growth and improve their frost resistance.

This year is a warm winter, but it is likely to be cold in late spring next year, which has a great impact on wheat and garlic. In the past, we didn't pay much attention to cold springs. Last year's cold spring caused many farmers to seriously reduce production. Remind everyone of the weather changes after March and April next spring. When there is frost, spray antifreeze again in advance, with green water to avoid frostbite. Although garlic is a cold-tolerant crop, garlic can survive the winter safely as long as proper planting techniques are mastered, laying the foundation for high yield next year.
