Leeks are hardy and drought tolerant, can they still live?

It should be able to survive, because leeks are harvested one stubble at a time, so they can survive if they are well maintained in the next period.

How to manage leeks in the second year.

1. Spring management.

Spring is the first peak period of leek growth, with fast leaf growth and vigorous plant growth. During this period, the level of field management has a direct impact on the yield of fresh leeks. Before returning to green, it is necessary to remove dried leek leaves and weeds in time, loosen the furrow surface, and tidy up the furrow, so that the base of the plant can better accept sunlight, increase the ground temperature, and promote germination.

When the soil temperature reaches above 0, the soil begins to thaw and leeks germinate. At this time, the temperature is still low, the transpiration is small, and the watering time and watering amount should be determined according to the weather and soil moisture; If the soil is wet, do not water; If the soil is dry, it should be watered back in time, with a small amount of water.

Light pouring is advisable. In spring, top dressing should be carried out, and urea should be applied per mu.

20 kg, deep hoeing after application, increase soil permeability, increase ground temperature, and promote the rapid growth of plants. Generally 35 40 days can be harvested the first knife leek.

Leeks have strong fertilizer tolerance, after each harvest, when the wound heals and the new leaves grow 2 3 cm, combined with watering 1500 2000 kg per mu to irrigate 15 2000 kg of ripe human manure or urea 15 20 kg, slightly dry after watering, timely cultivate and protect moisture, improve ground temperature, and achieve "knife top dressing". With the increasing temperature, coupled with scientific management, the second knife is generally harvested in 28 to 30 days, and the third knife is harvested in 25 to 28 days. The spring leek yield accounts for 2 3 percent of the total annual output to ensure a high yield of leeks.

Leeks are very drought-tolerant, afraid of waterlogging, and relatively cold-tolerant, and the leaves can tolerate low temperatures of -4 --5 during their growth, and the leaves will wither at temperatures of -6 --7. The suitable growing temperature for leeks is usually in the range of 15 -25, so if the plant is in this temperature range during the cultivation process, it can grow better.

The suitable growing temperature for leeks is usually in the range of 15 -25, so if the plant is in this temperature range during the cultivation process, it can grow better.

Do leeks freeze to death in winter.

Leeks will freeze to death in winter, because the cold tolerance of the plant is not good, if the outdoor temperature is very low in winter, the plant is easy to freeze to death. How leeks overwinter.

Watering: If leeks want to survive the winter smoothly, if the temperature is lower than minus 5 degrees Celsius after the beginning of winter, it is necessary to water the leeks with frozen water at this time, so as to avoid frost damage to the underground rhizomes.

Soil cultivation and root preservation: During the overwintering period, it is also necessary to cultivate the soil between the rows to the roots of leeks, and can also moderate Trim water-soluble fertilizer, which can not only prevent freezing, but also help plants loosen the soil, improve the soil permeability structure, and facilitate the absorption of nutrients by the roots of the plants.

Leeks are not tolerant to waterlogging and are afraid of flooding. If there is water for a long time, the root system of the plant will not be able to breathe, and the rotten roots will die. At this time, it is necessary to drain water in time, dig deep surrounding ditches, plough and loosen the soil in time, and replenish nutrients in time to promote plant recovery.

When the humidity is high, diseases are prone to occur, so it is necessary to use high-efficiency, low-toxicity, low-residue pesticides for control.

Leek roots belong to the fleshy roots. Like other succulent root crops, it is very susceptible to flooding. Accumulation of water in the seedbed for 8 to 10 hours may lead to root rot and death of leeks.

Most of the northern leek seedlings are high ridges and low margins, and the seedbeds are prone to water accumulation. Therefore, in case of heavy rain during the leek seedling stage, the stagnant water at the border must be discharged in time to prevent flooding and death.

Leek. Extended Resources:

1. Will leeks drown.

If you soak leeks every day, the roots of the leeks will not be able to breathe oxygen, and the leaves will not be able to photosynthesize, and the roots will rot first, and the leaves will turn yellow again, and then the leeks will slowly drown.

2. What should I do if the leeks are waterlogged?

After the leeks are flooded, they need to be drained in time, dig deep ditches around them, and they need to be cultivated in a timely manner to loosen the soil, loosen the soil, replenish nutrients in time, and promote the recovery of the plants.

Leek. 3. The time and frequency of leek watering.

In general, leeks need to be watered every 7 days. After the frost, the temperature gradually drops, the plant grows slowly, and the nutrients inside the plant are converted into bulbs and roots. At this time, it is necessary to reduce the amount of irrigation, and do not water in drought.

1) How often to water leeks in spring.

Do not water leeks before cutting them in the spring. After 3 days of harvesting, wait until the incision heals and the leeks grow out of the ground. Generally, it is watered once every half month.

2) In summer, the leeks are watered every few days.

In summer, the temperature is high, the water evaporates quickly, and the water demand for leeks is large. Generally, it can be watered once every 7 days or so. In case of drought, increase the frequency of watering.

Leeks are watered in autumn for a few days.

3) The temperature after the beginning of autumn is suitable. At this time, the leeks are growing vigorously. Generally, watering 1 2 times a month. Leeks are afraid of autumn humidity and excessive precipitation. Be sure to do a good job of moisture-proof drainage.

4) How long to leave leeks in winter.

Around the beginning of winter, the ground of the seedlings and leeks partially withered. Pay attention to antifreeze water. Water once a month and then water thoroughly. If the soil is not dry, it cannot be watered.

Leek.

The high temperature in summer led to less nutrient accumulation and high consumption of leeks, which affected the plant growth, and the leaf tissue fibers increased, the texture was rough, and the growth was weakened. Harvesting should be stopped from late June to early August to facilitate root raising. 8 Harvest l 2 times in September, stop harvesting after late September.

For the last 1 harvest, the stubble should be slightly higher. In particular, the leeks planted in the previous year are stopped harvesting during the high summer temperature, and they are sprinkled with a watering can once a day in the morning and evening to keep the surface moist, but not splashed. Due to favorable factors such as no cutting, sufficient fertilizer and water, and vigorous growth, leeks often have lodging in summer.

After lodging, it is easy to rot and induce epidemics, causing death. Measures to prevent lodging are: excessive nitrogen fertilizer; Do not overwater; Flood prevention in case of heavy rain; Leek leaves are too long, lodging may occur, and the leek leaves should be cut short.

Weeding. High temperature in summer and rainy in autumn cause weeds to breed and affect the growth of leeks, so they should be uprooted in time.

Pick the sprouts. Because leeks will consume a large amount of nutrients during flowering and fruiting, it will affect plant growth, tillering and nutrient accumulation, thus affecting the yield of the next year. Therefore, in addition to harvesting and planting, leeks should also be removed in time when they are young and tender, and high-yield plants should be cultivated.

Prevention and control of blight. High temperature in summer and autumn, or exposure to the scorching sun after rain, is prone to blight, and the symptoms are manifested as scalded spots near the ground, and the whole plant dies in severe cases. In terms of management, attention should be paid to drainage, prevent waterlogging, remove yellow leaves, maintain good ventilation between rows, and reduce disease damage.

It can also be used to irrigate roots with 50% carbendazim 500 times to prevent disease.

Control of leek maggots. In summer, the occurrence of leek maggots is more serious, and it can be slowly flowed into the ditch with 50% phosphine 800 times combined with watering. It can also be sprinkled with phosphine granules after mowing and fertilizing the land, or watering the roots with 20% "leek maggot net" kg per mu at the peak of leek larvae.

The above methods of waterlogging leeks will be explained to you here, hoping to help you better plant leeks.

The leek root system belongs to the fleshy root system, it is like other fleshy root crops, it is extremely afraid of flooding, and the seedbed can cause the leek to rot and die after 8 to 10 hours.

Leeks are very water-resistant vegetables, and if they are soaked in water all the time, they will die and rot for up to two days.

The leeks can't drown after being waterlogged for a few days, and once the water is drained, the vitality of the leeks is still quite tenacious and does not have much impact on him.

Leek leaves can tolerate low temperatures of -4 -5, and at low temperatures of -6 -7, the leaves begin to dieUnderground 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.

Leek is a kind of cold-tolerant and widely adaptable leafy vegetables, especially the northern leek varieties, the leaves can tolerate the low temperature of -4 -5, the leaves wilt at -6 -7, the temperature requirements for different growth stages are different, the appropriate temperature for seed germination is 15-18, the appropriate temperature for seedling stage is more than 12, and the most suitable growth temperature is 24-26 during the day and about 12 at night.

Leeks are very drought-tolerant, afraid of waterlogging, and have tenacious vitality. In spring, the whole leek is exposed to the sun for a few days, the stems, leaves, and roots are dry, and the bulb can still take root and sprout in the rain.

Leeks are quietly blind and resistant to high temperatures.

Leeks can tolerate the highest temperature of 30, its seed germination temperature is above 12, the growth temperature is between 15-25, and its underground part can tolerate lower temperatures.

Leeks prefer water or drought.

Leeks don't like water or drought. If it's too dry, it won't grow well, and if you water it too much, it will make the roots rot. It is a shade-loving plant that usually in cool, moist environments, its leaves can thrive and remain green throughout.

Causes of drought tolerance in leeks.

Leek stems are divided into vegetative stems and flowering stems. The vegetative stems of the annual or biennial are shortened and deformed into a disc, called a bulb disc. The shortened stems gradually grow to the surface, and gourd-like rhizomes form under the bulb disc.

Its rhizomes are vital organs for storing nutrients and guarantee a minimum of nutrients** even in drought conditions.

Leeks are drought tolerant or water tolerant.

Leeks are neither drought nor waterlogg-tolerant. Due to its underdeveloped root system, weak water absorption capacity and low leaf transpiration, it is required to keep the soil moist at all times and avoid excessive soil moisture. Different growing seasons have different water requirements.

Leeks are temperature-loving, waterlogg-resistant, drought-tolerant, suitable for soil moisture of 80-95%, air humidity of 60-70%. Broad-leaved leeks are relatively waterlogg-tolerant, have a certain degree of drought tolerance, strong disease resistance, and are suitable for planting in the open field with filial piety.

Are leeks afraid of flooding?

The root system of leeks belongs to the fleshy root system. Like other crops with succulent roots, it is extremely afraid of flooding. Accumulation of water in the seedbed for 8-10 hours may lead to leek root rot and death.

In the north of China, leek seedlings are mostly raised in high ridges and low furrows, and the seedbed is easy to accumulate water. Therefore, in case of heavy rain during the seedling stage of leeks, the water in the furrow must be drained in time to prevent drowning. There is too much water in the current location to drain out.

Soak leeks every day, the roots of the leeks cannot breathe oxygen, and the leaves cannot photosynthesize. The roots will rot first, the leaves will turn yellow, and then the leeks will slowly drown. Linglu.

Do leeks drown.

After the leeks are flooded, the stagnant water should be drained in time and the surrounding ditches should be dug well. It is also necessary to cultivate and loosen the soil in time, replenish nutrients in time, and promote plant recovery. When the humidity is high, it is easy to cause diseases, and it is necessary to use high-efficiency, low-toxicity, low-residue pesticides for prevention and control.

Leeks are shade tolerant. Leeks are shade tolerant. Leeks are suitable for medium light intensity and strong resistance to negativity. Usually maintained in a cool, moist environment, its leaves grow vigorously to keep the green color of the shirt.

Leek growth tolerance.

Leeks or twigs are drought tolerant or moist.

Leeks like to get wet, but I can't tolerate it. Its root system has weak water absorption capacity and low leaf transpiration. The soil should always be kept moist to avoid excessive soil moisture.

Are leeks hardy.

Leeks are hardy. It is a leafy vegetable with wide adaptability, especially the northern leek variety. Its leaves can tolerate low temperatures of -4-5 and wilt at -6-7. Different growth stages have different temperature requirements.

How many degrees of high temperature can leeks withstand.

Leeks are not resistant to high temperatures, the effective growth temperature is 5 30, the suitable growth temperature is 12 24, the optimal growth temperature is 15 20, and the temperature is more than 25, which is not conducive to the normal growth of leeks. Plants grow slowly, and growth is largely stagnant when temperatures exceed 30.

1. Southern varieties of leeks are planted in the north and will not freeze to death in winter.

Leeks belong to the lily family perennial root vegetables, which are adaptable, cold and heat resistant, and are cultivated everywhere in China.

2. Leek growth habit Leeks belong to the lily family perennial root vegetables, with strong adaptability, cold and heat resistance, and are cultivated everywhere in China. Many areas in the south can be produced all year round, although the aboveground part of the north dies in winter, the lower part enters dormancy, and the topsoil thaws in spring and germinates and grows.

1. Temperature: leeks like cold and cool, cold and heat resistant, the seed germination temperature is more than 12, the growth temperature is 15 to 25, and the underground can withstand lower temperatures.

2. Light: medium light intensity, strong negative resistance. 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.

3. Moisture: the appropriate air relative humidity is 60-70%, and the soil moisture is 80-90% of the maximum water holding capacity in the field.4 Soil nutrition: strong adaptability to soil texture, suitable pH. The amount of fertilizer required is large, and the fertilizer tolerance is strong.

3. The climate of northern China.

1. The temperate monsoon climate is predominantly in northern China. The climate is characterized by four distinct seasons throughout the year, with warm and rainy summers and cold and dry winters. The annual precipitation in the northern region is mostly 400-800 mm, and the precipitation is concentrated in February, with heavy rainfall, at this time, the river water rises sharply, and the river is easy to flood; The spring of each year has little rain, and there are often droughts (severe drought in spring and heavy rains in summer).

Precipitation in northern China from February to April has been below the multi-year average since then, with the exception of 1998. At this time, under the influence of La Niña, the northerly airflow prevailed in northern China, while the southeast warm and humid airflow was relatively weak, coupled with the unfavorable coordination of cold and warm air, which has not been able to form ideal rainfall conditions in northern China, resulting in continuous lack of rain and dry weather.
