In the north, winter is cold and most vegetables are not suitable for open-air cultivation. Even when grown in large huts, they require hot sheds, and cold sheds without hot walls require warmer measures to meet the growth temperature of guacamole vegetables. Nevertheless, nature has produced cold-resistant athletes. The following is a description of several types of vegetables that are generally frozen in the open air in the north — not expected to grow normally, mostly in the cold。
1. Spinach
The winter spinach is more chilly, with seeds growing at above 4°c, short-lived low temperatures of 3-4°c, representing the northern winter vegetables. Choosing spicy spinach is more chilly than round leaf spinach. Seeds can be soaked prior to seeding, increasing the incidence. Upon sowing, the soil is kept moist and nitrogen fertilizers are properly pursued to promote leafy growth。
2. Crushed vegetables
Collapse, which is a kind of cross-flower vegetable, is a bit like cabbage, but is shorter than a long cabbage, growing almost on the ground, with leaves like petals in a circle, coloured in black and green, for one thing, that is to fight cold. Vegetables are particularly resistant to cold, and those that are baptized with frost have a unique sweet taste and a soft taste。
Three, kale
The kale is a semi-cool-resistant vegetable with an optimal growth temperature of 12-20 degrees, short-lived tolerance for low temperatures of 12 below zero, preference for cold, wet climates and the need for sufficient sunlight to avoid planting during high summer temperatures. The demand for soil is low. Range 20-30 cm. Care should be taken to combat pests and insects during growth, and appropriate fatting should be pursued。
Four, cauliflower
Vegetables are cold-resistant vegetables. They are a multi-year herbivorous plant with a chilly climate that can grow normally at below 5°c, leaves resistant to below 4°c low temperature and roots resistant to below 15°c. Selenium is cold-resistant and has a low demand for light and suitable for low-temperature and light conditions in winter. In the northern region, the underground part of bellies can go into hibernation during the winter, while the ground segment may die. After the spring temperature rises, cabbage will grow rapidly and grow again。
Five, garlic
Garlic is a cold-resistant crop that can withstand temperatures of less than 10°c, and the growth of garlic is not much affected by temperatures around 0°c. At temperatures below 2°c, the growth of garlic is affected. There are different varieties of cold resistance, and white garlic is better at cooling than purple garlic. Garlic is suitable for planting in the full light of spring and autumn. Fall is the best time to grow garlic. In winter, open-air cultivation generally does not freeze to death, but is slow to grow, and covering membranes rises in temperatures to the point where garlic grows more winterly。
Six, snow
The coldness of the snow is good enough to withstand temperatures of 7-8 degrees below zero and to adapt to the cold climate, which is conducive to the growth of buds. The snow is cold, growing at 15-20°c, radiant and infertile. The seeds are soaked 2-3 cm that they are then suppressed in order to generate seed. The seedlings are produced in a timely manner. Reasonable fertilization during growth is required to promote plant growth。
Seven, celery
Celery has some resistance to cold, and winter celery is planted at a high temperature of august to september. Once its seed exceeds 30 degrees, it ceases to sprouts, with a minimum seeding temperature of 4°c, and seedlings withstand temperatures of between 4°c and 6°c below zero, prefer cold environments and grow well in the north. Protection from freezing is required at below 4°c。
8. Winter food
Winter cuisine has a cold resistance capacity of around 5°c and can grow normally in a milder environment. It has an appropriate growth temperature of 15-20°c, and its quality is improved when planted at low temperatures. The more branches are collected, the more they are collected, the more they are collected。
These are cold-resistant vegetables that are grown in the north in the open, which have a strong ability to withstand the cold and generally survive the cold winters, but which wait until spring temperatures return。
