Can leeks grow in caves, can leeks grow in winter

Yes, leeks that do not grow without light are called leeks, which are yellow.

There has to be a certain amount of light that can be grown and planted in it!

Expert answers.

Leek is a cold-tolerant vegetable, which has a wide range of adaptation to temperature, and can be cultivated in all parts of China for overwintering and summering, and is a perennial root-based vegetable.

Leeks are cold and heat tolerant, and the suitable temperature range for growth is 13 22, when the temperature exceeds 23, the nutrient accumulation of plants decreases, the leaf cellulose content increases, the yield decreases, and the quality decreases. Especially under the conditions of high temperature, strong light and drought, the texture is coarse and hard, and the value of the commodity is poor.

Leeks have different temperature requirements for different growth periods, the germination period is the seed germination to the young shoots stretching out and growing the first true leaf, the minimum temperature of seed germination is 2 3, the suitable temperature is 15 18, and the number of germination days is determined by the ground temperature, generally about 10 20 days; The seedling stage is the first true leaf stretching out to a fixed value, about 40 60 days, the growth temperature is 12 24, and the growth is poor above 25; The optimal temperature for stem and leaf growth is 12 24 during the day, and the temperature requirement for the flowering period is high, generally 20 26. In the cultivation of protected areas, due to the high humidity and weak light in the protected areas, the temperature is slightly higher, and the quality of leeks will not be reduced. Generally no more than 23 during the day, each knife can be increased by 3 5 than the previous knife, and the maximum is not more than 30; The suitable night temperature is 7 8, the temperature difference between day and night is about 10, the temperature difference is too large, and the leeks are easy to condense on the foliar surface, causing diseases.

Leek varieties are different, cold tolerance is also different, the leek varieties native to the south like warm climatic conditions, cold tolerance is poor, and the varieties produced in the north have strong cold tolerance. There are many southern varieties that cannot even overwinter in the open in the north, so special attention should be paid when choosing varieties.

Under the condition of open field, or in the spring plastic arch shed with low temperature conditions, the temperature is about 35 at noon during the day, and the temperature drops to 2 at night, and the plants can still grow normally. However, frost damage occurs when overwintering cultivation in greenhouses, because the light in the greenhouse is weak, the humidity is high, the leaf tissues are tender, and the cold resistance is low.

The growth temperature of leeks is 15 to 25, it likes cold and cool, cold and heat resistance, the suitable temperature for seed germination is more than 12, and the underground part can tolerate lower temperatures.

The temperature requirement of leeks is to prefer cold and cool climates, with a minimum temperature of 2-3; The growth temperature of the seedling stage is 12-18, and the growth is slow when it exceeds 25. The suitable temperature for leaf growth is 15-25, not tolerant to high temperature, when the temperature exceeds 25, the plant grows slowly, and the leaves turn yellow and even wilt when the temperature exceeds 30. When the temperature exceeds 25, ventilate and cool down.

Leek, (scientific name: a.) tuberosum rottl.

ex spreng.Aliases: abundant ben, grass stalactites, yang grass, lazy vegetables, long-lived leeks, aphrodisiac grass, flat cabbage, etc.; It is a perennial herbaceous plant of the lily family, with a special strong odor, the rhizome is horizontal, the bulb is narrow and conical, and it grows in clusters; Scaly outer skin yellowish-brown, reticulated fibrous; leaves basal, strip-shaped, flattened; Umbel inflorescence, apical.

Leaves, flowers and flowers are eaten as vegetables; Seeds can be used in medicine, which has the effects of tonifying the kidney, strengthening the stomach, refreshing, stopping perspiration and astringency. In traditional Chinese medicine, some people call leeks "intestinal cleansing grass".

Leeks are adaptable, cold and heat tolerant, and are cultivated everywhere throughout the country.

Leek's temperature requirements: sex likes cold and cool climates. The suitable temperature for germination is 15 18, and the minimum temperature is 2 3; The growth temperature of the seedling stage is 12-18, and the growth is slow when it exceeds 25. The suitable temperature for leaf growth is 15 25 , and it can also grow at 10 15; It is not resistant to high temperatures, when the temperature exceeds 25, the plant grows slowly, and when the temperature is higher than 30, the leaves turn yellow and even wilt; The leaves can tolerate low temperatures of -4 -5, and in the low temperature environment of -6 -7, the leaves begin to die; Underground rhizomes still safely overwinter at 40.

However, the southern varieties are more resistant to low temperatures in the aboveground and weaker in the underground parts.

Leeks are not suitable for planting in autumn, leek seedlings grow slowly, should be sown early, and sowing is appropriate from late March to late April. Leeks like cold and cool, cold and heat tolerant, the seed germination temperature is more than 12, the growth temperature is 15 to 25, and the underground can tolerate lower temperatures.

Medium light intensity, strong resistance to negatives. However, if the light is too weak, the accumulation of photosynthetic products is less, the tillers are less and weak, the yield is low, and it is easy to premature aging. The light is too strong, the temperature is too high, there are many fibers, and the quality is poor. The suitable air relative humidity is 60-70%, and the soil moisture is 80-90% of the maximum water holding capacity in the field

It has strong adaptability to soil texture, suitable pH, large fertilizer demand, strong fertilizer tolerance, native to southeast Asia, has been widely cultivated in the world, and is widely cultivated in China.

Leeks, not suitable for growing in winter.

The overwintering cultivation of leeks is mainly in the cultivation method of germinating after the leeks return to their roots in autumn, through the dormant period, and then in the environment with protective facilities, the appropriate temperature and humidity environmental conditions are given.

Leeks can be planted twice a year, mainly in spring and autumn, most of the spring sowing time is around March and May, and autumn sowing is generally after September. The growth temperature of leek leaves is 18 20, if it is lower than 5, the growth stops.

If it is higher than 25, leaf tip rolling, leaf burning, and death will occur. In order to ensure that more green leeks can be produced during winter and spring, the main purpose is to reduce the number of harvests in autumn, so that more nutrients can be stored in the roots and stems for the growth of winter and spring.

Yes, in the greenhouse, or the leek bushes we eat in winter?

No, leeks are leeks.

Leek (scientific name: allium tuberosum), also known as Qiyangzi, is a perennial herbaceous plant of the genus Allium in the family Lycoris family. The leaves and flowers are edible when they are tender.

Vegetarians with religious beliefs such as Buddhism and Taoism are not allowed to eat leeks, which have been traditionally classified as meat since ancient times. "Plant pentochotin" does not avoid plant pentacyte, such as leeks.

Characteristics - Leeks are perennial evergreen herbaceous plants, root-bearing, hardy and prefer to grow in a humid and fertile environment, with burnt yellow leaf tips in full sun and dry environments. Like most alliums, leeks have bulbs, fibrous roots, and slender underground stems. The dark green leaves are elongated, flattened, ribbon-like, and the closed leaf sheath forms a pseudostem; It is about 10 30 cm long and about cm wide, and the leaves are clustered and grow from the pseudostem (leek).

"韮" is a variant of "韭", which has long been listed in the "First Batch of Variant Character Sorting Table". According to the circular issued jointly by the Ministry of Culture and the State Character Reform Commission on December 22, 1955, the variant characters listed in the table shall cease to be used, except for those used as surnames, which may retain the original characters in publications without alteration. "Leek" is the name of the vegetable

韮 is not used as a surname here, so "韮" should be abolished.

Leeks and leeks are the same vegetable name.

Some farmers believe that leeks have a strong ability to regenerate, and they tend to harvest too much Zhao anyway. Although the yellow yield is higher in a year, due to the lack of nutrients in the plant, it cannot maintain the vigorous growth in the future, and the hand causes premature aging. The scientific method of unharvesting is based on the growth law of leeks, the strength of the growth potential and the amount of fertilization.

As far as the four seasons are concerned, Di Ji is the season when the plant accumulates military nutrients, generally should not be harvested, the leek buds softened by the soil can be harvested in winter, the Zhao is harvested two to three times in the spring, and the leeks grow slowly in summer, and the leek moss can be harvested. According to this unharvested method, green leeks are harvested three to five times a year. If the industry is already old and loses the update in the coming year, you can increase the number of engravings.

The method of harvesting leek is related to the old man of leek and the output of the next harvest. Therefore, when harvesting, dig up the side of the new soil first, leave the pile one to 1.5 inches away from the mud surface and carve too low, because the meristem of the leek is at the base of the leaf box, and if the carving is too low, it will hurt the meristem at the base of the leaf sheath and affect the next yield. How many times a year is the best time to harvest leeks?

Xu Jiantao $Heilongjiang Province Sugar, Tobacco, Wine and Vegetable Company "Zheng" Some farmers believe that leeks have a strong regeneration ability, and they will grow anyway if they are cut, and they are often harvested too much. Although the yield is higher in the middle of the year, the plant cannot maintain vigorous growth later due to insufficient nutrient accumulation, resulting in premature aging.

Growing for about 20 days is a stubble, the growth rate is very fast, if the time is long, the leeks will be old, and it will not taste good.

Leeks grow very fast, they can be harvested once in about 20 days, and after a long time, the leeks will be old and not tasty.

The growth cycle of leek seeds is three to four months, and when it grows to about 15cm, harvesting is the most suitable. Among them, the growth speed of leeks is related to root water and fertilizer, light, temperature, humidity and density.

Generally, it can be harvested once in twenty days, and no matter how many days there are, it will not be old, and it will not taste good.

It depends on your fertilizer, I am so scared that I can't sit still, if the fertilizer is enough to grow in a week, if it is relatively high, it may not be in three weeks.

I usually grow for about two weeks, or half a month before harvesting, and it tastes a little better.

There is no precise time regulation, you can cut it once a month, and you can eat it.

Leek seeds are harder, absorb water and swell slowly, in order to make the seedlings appear fast, soak the seeds before soaking, start to soak in warm water of 40, stir constantly, when the water temperature drops to below 30, continue to soak the seeds for 12 hours, and then scrub them with water, spread them out to dry for a while, disperse the moisture on the surface of the seeds, wrap the seeds with a damp cloth, put them in 15 20, rinse them with water once a day, 3 5 days later, when most of the seeds expose the white tip, you can sow seeds. If the soil and temperature are suitable after sowing, the germination time of leek seeds is about a week.

Hydroponic leeks can be eaten in about 1 to 2 months.

Generally 15 to 30 days is fine.

If you plant it, you will have to wait half a month to eat it.

Precautions for overwintering leeks in the open field.

When the temperature is below minus 5, the ground begins to freeze, and the leeks begin to enter the overwintering period. At this time, it is necessary to pour frozen water in time. In this way, the underground rhizomes can be avoided from frost damage, prevent spring drought, and lay a good foundation for early onset and rapid growth in spring.

Watering too early, the ground is not frozen, the soil water is dispersed quickly, and the moisture storage effect is poor; If the watering is too late, the soil will freeze, and the frost damage will be aggravated after watering, and the root system will be suffocated and killed by lack of oxygen. Therefore, watering is most suitable when the soil is frozen day and night.

Second, it is necessary to reapply wax fertilizer Wax fertilizer can not only prevent cold and increase temperature, but also have the effect of winter and spring. Wax fertilizer is better to rot human feces, and 1500 2000 kg per mu is applied.

Third, during the wintering period, the soil between the rows is cultivated to the roots of leeks, which can not only prevent freezing, but also play a role in loosening the soil and improving the permeable structure of the soil, which is conducive to the absorption of nutrients by the roots. Generally, two or three times during the entire overwintering period can be cultivated.

Fourth, the leek furrow should be covered with cow, horse manure or hay on the leek furrow surface, which can protect moisture, increase temperature and prevent freezing. 2500 kg of cow and horse manure or 250 300 kg of firewood and grass per mu can be evenly covered with leek furrow noodles.
