How do you make open field grown coriander safe for wintering? Are there any wintering measures?

The coriander, if you want to safely overwinter is very easy, cover the coriander directly with plastic sheeting, and cover the corn stalk or straw curtain at night and other things, it will not only not rot, but also grow slowly in the ground, which can keep it fresh My grandmother's according to her own consistent experience, told me that coriander is also relatively cold-resistant, and it can be safely winterized above minus 3-5 degrees.

<> If you want to take root again, water once when there are 5-6 leaves. Before freezing, wind barriers or ground cover are set up in some areas to make it safe to overwinter and harvest early. When the soil freezes at night and is isolated during the day, the frozen water is immediately filled, and the ternary compound fertilizer is applied along the water.

Or diammonium 10-15 kg, cold, with a large area of planting coriander, have to be fixed with an iron frame, and then covered with plastic film, during the day there is sunlight can be directly like this, if it is at night also have to cover a long period of low temperature and high humidity will inhibit the formation and growth of vegetable roots, in this period, try to avoid watering. Severe water shortage of greenhouse vegetables, should be harvested and sold best to build a shed, you can use bamboo.

Build a bow-shaped shed with plastic film.

When the weather is too cold, it can be covered with a layer of straw. In this way, you can grow all the time without being afraid of frost to stop growing and purple leaves, and you can't let the temperature in the shed be too high, and you have to take a small amount of water at noon when the weather is good.

method. In addition, if the soil moisture is large, it is necessary to remove the film and loosen the soil in time, and cooperate with the measures of supplemental foliar fertilizer to increase the layer of grass fence insulation. If it is planted in a small area only for your own consumption, then directly cover the coriander with a layer of plastic film, and press the grass around it to make a curtain cover, and if there is no condition, use the kind with more branches and forks, and put it on the coriander ground.

Be careful not to overwhelm the coriander, and then cover the large branches with dry straw to keep warm and not crush the coriander and hinder its growth. On top of the parsley. Four corner ends.

Pressed with earth to prevent strong winds.

Run, blow away has no effect, but also ensure that it can.

The most common cold-proof measure is to sprinkle plant ash, plant ash contains more potassium elements, as well as a variety of trace elements, etc., before the arrival of the cold snap, the plant ash is evenly sprinkled on the roots of coriander, plant ash can be used alone, can also be mixed with sawdust and plant ash, grass ash and wheat bran, rice bran mix, etc., has an obvious auxiliary heat preservation effect.

Coriander can be covered with mulch, which will maintain the temperature and also allow moisture to form, so that it will not freeze to death. There is also the construction of a greenhouse on the outside so that you can survive the winter.

You can give some potassium to the coriander in the winter, so that it can be safe to overwinter. You can cover the coriander with plastic film, which can be very frost-resistant and cold-proof.

Yes, it is possible to soak it in hot water, and it is also good to soak it in hot water. It can be given to coriander seeds to have a bactericidal effect. But do not use hot water at too high a temperature.

It is easy to burn coriander seeds. It is best to soak in hot water at about 50 degrees Celsius. About 10 minutes.

Then soak the seeds with water for 12 hours, clean them, soak them in water for 12 hours, and then put them in a cloth bag at a temperature of 8 10 to germinate for 5 7 days, turn them once a day, and about 30% of the seeds can be sown when they are exposed. The main root of coriander is stout, the lateral roots are also numerous, the absorption capacity is strong, the stem is short and tender, the leaves are pinnate compound leaves, alternate and long. The flowers are small and white, and the fruit is a double hanging fruit, with two seeds inside, the seeds are fruits, which are fragrant and can also be used as spices for seasoning.

More than 12 hours of long sunshine can promote the development of coriander, there is weak light, the growth will be slow, the plant is short, the leaf color is poor, the taste of coriander is light, that is, the quality is usually poor, of course, the yield is not good. Note that the temperature of hot water for soaking coriander seeds in advance should not exceed 35, because the skin of the coriander seeds is relatively thin and cannot withstand high temperature soaking.

Blight can be controlled with fungicides such as oxazine and fumeishuang, leaf spot can be controlled with prochloraz, difenoconazole, etc., sclerotia and gray mold can be controlled with fungicides such as sclerotinitum, Nonliling, and dioxazole, and thiobacterium can be used for soft rot. One round seed, after crushing, it becomes two to four seeds, I don't believe you can experience it yourself. As long as the soil is moist when planting, if you are not at ease, you can spread this blade of grass on it.

The seed shell of coriander is hard, it is best to sow the coriander seeds vigorously and then soak them in warm water for 24 hours before sowing them, so that the coriander seedlings are fast and neat. Before sowing, the land should be prepared, the soil should be meticulous, make the bottom of the foot, turn the ground after applying the plantar fertilizer, rake the flat, knock the big stump, remove the stone bricks, make the flat furrow sowing of rice, sow the seeds, draw the ditch according to the row spacing of 20cm, and sow the seeds.

Pay attention to the time of the seeds in the water should not be too long, one night can be, the time is long, the seeds are soaked through, can not breathe oxygen in time, the seeds will not germinate, in addition to soaking in water to do a good job of sterilization, so as not to be infected by germs, even if germinated, the sprouts will be weak resistance and infected with germs to die.

It is necessary to pay attention to the issue of insect control and nutrition, because to grow this plant, it is necessary to pay attention to pests and nutrient supplementation.

It is very important to pay attention to the temperature and humidity. And the seeds need to be pressed open so that healthy cilantro can grow.

It is important to remember that the soaking time is not too long or too short, otherwise it will affect the development of the seeds.

The sowing time of overwintering coriander varies according to regional climate differences. The post-sowing growth period is as long as 5-7 months, with sowing in North China from early September to late October, Northeast China from mid-August to early September, and Henan at the end of October.

Precautions for planting overwintering coriander.

Note 1.

The temperature of overwintering coriander rises in the following spring, and the mulch is quickly removed, which is conducive to raising the soil temperature and promoting early greening. The heart leaves begin to move, and the green water is gently poured after returning to green, but it is advisable to irrigate too early or flooded with large water, so as not to affect the ground temperature and cause a slow return to green. Combined with irrigation to apply 10-15 kg of urea per mu to ensure the absorption of nutrients after regreening, it is generally enough to water 1-3 times.

Overwintering coriander should be harvested in time to prevent sprouting, so as not to lose the value of the commodity.

Note 2.

If it is cultivated in the open field, it should not be watered too much at the seedling stage. When the seedlings grow to 10 cm, the plants are growing vigorously and should be watered frequently to keep the soil surface moist. Watering at the same time as the top application of fast-acting nitrogen fertilizer 1 to 2 times.

Pay attention to cultivating and proper seedling, and pull out weeds when thinning. In summer, it is necessary to properly shade and prevent heavy rain from scouring, and drain water in time after rain to ensure that the seedlings emerge neatly.

Note 3.

If it is cultivated in a greenhouse, it should be poured with frozen water before winter to facilitate the seedlings to overwinter. In January, there is no need for ventilation from January to February. When the seedlings return to green, tillage, soil loosening, and weeding are carried out.

When the seedlings are 10 cm high, the plants enter the vigorous growth period, and the greenhouse is maintained at 15 to 25. About 15 kg of ammonium sulfate is used each time per mu, and it can be harvested in advance by topdressing 1 to 2 times.

Coriander can be grown all year round, but it is generally grown in spring and autumn, so it is now possible to grow coriander. Now there are more autumn coriander planted in September, but those heat-resistant varieties can also be planted in August, and the germination rate is not too good, but the benefits are good! In addition, there are northern sayings:

The first radish and the second cabbage, coriander can also be planted together with cabbage, but the emergence of seedlings is slower, and moisturizing measures need to be taken, such as covering wheat oranges, hay, etc.

You can plant coriander before and after Qingming, and don't sprinkle the seeds too densely. Don't bury it deeply, just sprinkle a thin layer of soil after sprinkling the seeds, otherwise it will not bud, or the sprout will be slow. Water every day for the first three days, pay attention to spraying, do not water directly with a water hose, it will wash away the seeds with biological characteristics such as strong cold resistance, short growth period, easy cultivation and so on.

From sowing to harvesting, the growth period is 60-90 days, and it can be cultivated under different natural conditions in various parts of China. It is generally required to be cultivated on sunny and rainy soils, fertile soils, loose calcareous sandy loam. It is most sensitive to phosphate fertilizers, which can increase the content of essential oils.

During the fruiting period, the weather should not be dry, and the soil should be moist to make the virgin full and full. Cultivation techniques are propagated with seeds. In northern China, the seeds are sown in July-August and harvested before October, while in the warm regions of the south, they are sown in October-November and harvested in the spring of the following year.

Spreading and stripping can be sown, and the amount of sowing is sown every 1hm2. The fruit is rubbed before sowing to allow the seeds to come into contact with the soil, absorb water and promote germination. It should not be irrigated when sowing, and then irrigated after 4-5 days, and germination can occur after about 5-9 days.

When the height of the seedlings is 5-8cm, the seedlings are thinned with a plant spacing of 10-15cm, and fertilizer and irrigation are applied 1-3 times.

Sow in early September! It's better if there is a greenhouse! Sow in several parts! It's better every half a month every time!

Parsley can also be grown. But shade the plants. When watering, you must choose morning and evening, don't water at noon, it is easy to burn seedlings. Fertilizer is also applied every half month in the morning and evening.

Coriander can also be grown in the summer when the temperature is high, and you can choose varieties that are resistant to high temperatures, and when the temperature is very high, you can use a rain shelter and shade netting to cover it.

You can plant coriander in summer, choose the soil is more fertile, have good water and fertilizer retention performance, can be watered in drought and drained by waterlogging, and have good permeability It is better to sow coriander in summer. After sowing the seedlings, the seedlings can cover the furrow surface, so that the evaporation of water is reduced, and the temperature is reduced. The method of spreading is:"Sow two furrows first, and leave one furrow"。

Weeding is carried out when the seedling height is 4-5 cm, and the seedling spacing is guaranteed to be 2-4 cm. After thinning seedlings, combine irrigation to chase a thin manure water. When the seedling height is 7-8 cm, the first fertilizer should be fertilized, and the amount of fertilizer should be large, and ammonium sulfate should be applied per mu.

Summary. Hello, I am glad to answer for you that coriander, also known as coriander, is one of the more cold-resistant vegetables, if it encounters a continuous low temperature state, coriander is susceptible to frost damage. Most of the leaves in the aboveground will be freeze-dried because the temperature is too low, leaving only one heart leaf, and the extremely cold weather will even suffer from freezing to death, the "La Niña" phenomenon will cause the appearance of severe winter, which has a certain impact on the safe wintering of coriander, and the coriander sown in the open field, it is best to take some cold-proof and warm measures to ensure that the coriander is not frozen to death.

Hello, I am glad to answer for you Wu Song Coriander is also known as coriander, which is one of the more cold-resistant vegetables, if it encounters a continuous low temperature state, coriander is susceptible to frost damage. Most of the leaves in the aboveground part will freeze-dry because the temperature is too low, leaving only one heart leaf, and the cavity orange liquid will even suffer from freezing to death in extremely cold weather, and the "La Niña" phenomenon will cause the emergence of severe winter, which has a certain impact on the safe wintering of coriander, and the coriander sown in the open field, it is best to take some cold-proof and warm measures to ensure that the coriander is not frozen to death.

Before the arrival of cold air, can not harvest coriander, should be into the auspicious stove line to increase cold and warm measures, in the rural open field planting nuclear draft of coriander winter, the most common cold-proof measures is to sprinkle plant ash, plant ash contains more potassium elements, as well as a variety of trace elements, etc., before the arrival of the cold snap, the plant ash is evenly sprinkled on the roots of the coriander, plant ash can be used alone, can also be mixed with sawdust and plant ash, plant ash and wheat bran, rice bran mixing, etc., has an obvious auxiliary heat preservation effect. Spray foliar fertilizer to improve frost damage resistance, before the arrival of the cold wave, you can carry out foliar spraying plant antifreeze, or spray potassium dihydrogen phosphate aqueous solution + Tianda 2116 cell membrane stabilizer. If there are conditions, you can also choose to cover the plastic film to change the banquet filial piety, is a better way to reduce frost damage, after covering the plastic film, and then cover the top with a layer of straw for insulation, you can safely pass the cold winter, when the temperature rises above zero, you can gradually remove the straw.

For the coriander in the field to overwinter, it is necessary to cover all the coriander with a mulch film, and puncture a few small holes on the surface of the mulch film for ventilation. Before winter, it is necessary to apply a well-rotted organic fertilizer and irrigate a cold water. To grow coriander, it needs to be placed in semi-shade and exposed to scattered light.

During its growth period, nitrogen, phosphorus and potassium compound fertilizers need to be applied to promote growth.

If you want the coriander in the field to overwinter, you need to take some cold protection measures. It is necessary to use a mulch film to cover all the vanilla, and prick a few small holes on the surface of the mulch film to allow the vanilla to breathe and avoid the carbon dioxide being expelled after respiration inside the mulch.

Before entering the winter, it is necessary to apply a low concentration of rotting organic fertilizer to the coriander to make the coriander have enough nutrients. At the same time, irrigate the coriander in the ground with cold water once, so that the coriander has sufficient moisture.

To grow coriander, it is necessary to prepare loose and fertile soil with good drainage and air permeability. Vanilla has a greater need for light, but is afraid of strong light, so it needs to be placed in semi-shade to receive scattered light. Spring, autumn and winter allow it to receive scattered light, and the summer heat needs proper shade.

Coriander has a greater demand for water, but is not tolerant to stagnant water, and needs to be watered every three days in spring and autumn, once every half a month in winter, and once a day in summer. This will ensure that the coriander has enough water and will also prevent the herbs from standing up and causing root rot. During its growth period, nitrogen, phosphorus and potassium compound fertilizers need to be applied to promote growth.
