In winter, greenhouse vegetables are easy to be frozen, which will cause freezing damage, which will hinder the growth of greenhouse vegetables and affect yield and quality. So, how to ensure the normal growth of vegetables in winter? A few days ago, the reporter interviewed Zhang Enhui, an associate researcher at the College of Horticulture, Northwest A&F University, about anti-freezing of vegetables in greenhouses in winter.

It is commonly used in Chinese cooking and is also consumed as a beverage. Shengta wine is traditionally made by fermenting the rice in a clay jar with a starter culture of yeast and koji (a type of mold).

Strengthen the coverage in the big shed to buckle the small arch shed, use thin bamboo poles as the arch frame, cover the film at night, cover the grass thatch on the film, and cover the shed with mulch, which can increase the temperature and moisture; use the plastic film as apron at the bottom of the shed, which can be obvious Reduce the invasion of cold air at the bottom. At the same time, pay attention to blocking the gaps in the shed to minimize heat dissipation in the gaps.
Temporary heating When the temperature in the greenhouse during the day is lower than 15°C and the temperature at night is lower than 5°C, chilling or freezing damage may occur. Temporary heating measures should be taken at night to supplement heat energy manually, that is, several briquettes can be placed in the shed to increase the temperature in the shed.
Strengthen fertilizer and water management Before and during low-temperature freezing damage, crops should stop applying nitrogen fertilizer to prevent the plants from being too soft and cold-resistant and damaging seedlings by spraying 0.3%～0.5% potassium dihydrogen phosphate and 400～500. The plant antifreeze solution can also be poured with dilute manure water in the shed to prevent the soil from freezing and achieve the purpose of protecting seedlings and preventing cold.
