When will cilantro be grown in the open field in the northern region, and will it be possible to gro

In the north, there is an option to grow coriander in August and October every year. These two times are the most suitable times for planting coriander in the open field in the northern region, and it is not the most suitable time to plant coriander at this time, because it is in the summer of July, and the weather is relatively hot.

In the north, the beginning of August is not so hot, which is more suitable for growing coriander in the open field, and there is no snow at that time, which will not hide the growth space of coriander. In October, the temperature will slowly drop, and at this time, you can also sow coriander, because the temperature of coriander is between 15 degrees and 20 degrees, and the temperature in these two months is just within this range, so you can plant coriander in the open field. However, if you choose to sow seeds now, it may cause the growth of coriander to be slow, because after 30 degrees Celsius, the coriander will stop growing.

Before planting coriander, you need to prepare rich trace elements and soft soil, and the seeds need to choose some more robust seeds, because this is more resistant to other things such as germs, and after soaking in warm water, you can take it out for later use. Then the selected seeds are sprinkled on the surface of the soil, and then a layer of fine soil can be placed there to wait. After almost half a month, you can see that the coriander seeds will germinate.

When sowing, it is necessary to separate the distance of each seed to avoid being too dense, which will affect the sunlight absorption of each seed and avoid uneven irradiation.

The air in the north is drier and not as humid as in the south, so the cultivation of coriander needs more water, and someone needs to irrigate the coriander seeds regularly and quantitatively to maintain the moisture of the soil, so as to better allow the coriander to grow. The water quality requirements are also very strict, and pure water is required, as well as some mountain spring water, and some unpolluted river water. There are also the necessities needed for plant growth - fertilizer, fertilizer needs to be nutritionally balanced, can be some inorganic fertilizer or have the opportunity, can speed up the growth of seeds.

Some people hate the taste of coriander, while some people like the taste of coriander, which is mostly used for seasoning and condiment. In the market, the sales of coriander are still very good, and coriander is also known as lazy food, compared to other kinds of vegetables, coriander is also very easy to grow, do not need to spend too much thought and time on it, and can also quickly harvest results. The high sales volume and easy to grow also make coriander one of the vegetables grown by many people.

It can also be planted during the Chinese New Year, so it can continue to grow as long as it is simply kept warm.

Coriander is a polarizing food, people who like it very much, and people who don't like it can't touch it at all, in fact, it is not particularly difficult to plant, as long as you give a certain amount of soil, and fertilizer, at the right temperature, you can grow vigorously.

Coriander can be grown in the open field in the spring and autumn in the northern regions, and it can now be planted in August.

Coriander can be grown in the north in August in the summer, and around October in the winter, it is best to grow coriander on land.

Coriander is generally not at any point in time, and now is also a good time to plant.

Coriander can be grown all year round. In general, coriander can be planted around March in spring and October in autumn, but coriander can be planted up to three times in a year on the same plot, so that the growth of coriander will be better.

In addition to the slow growth in winter, the summer is hotter, which is not conducive to the growth of coriander, in the same field a year, that is, planting about three stubbles, if the planting plot is replaced, it can be planted many times, and it is listed in batches.

Coriander is a vegetable crop that prefers cold and semi-cold-tolerant, and the suitable temperature for growth is 17-20 degrees, and the higher the temperature within this growth range, the faster it grows.

About seedling management of coriander

1. When most of the coriander seedlings emerge, the ground cover should be removed in time, if the temperature of germination and seedling emergence is relatively high, attention should be paid to timely shading and cooling, if the temperature of germination and seedling emergence is relatively low, this wild suspicion should pay attention to building a small arch shed in time for thermal insulation protection.

2. When the coriander seedlings are basically 5-7 days after the whole is out, the seedlings should be timed (pull out the seedlings that grow too dense and too crowded), and wait until the coriander seedlings grow 2-3 leaves or the seedling height reaches about 3 cm.

The northern region can grow coriander, coriander is a kind of seasoning vegetable we know, it tastes, likes to eat, the more you eat, the more fragrant, when cooking vegetables will generally put a little, I don't like to eat, and I'm afraid when I smell it. Coriander is a kind of vegetable that many people like to grow in the countryside, generally in spring and autumn are planted in the vegetable garden, but in some areas, some people grow coriander all year round, but in the vast majority of areas, <>

It is usually planted more in spring and autumn, and the climatic conditions in these two seasons are more suitable for the growth of coriander. Coriander is a relatively cold-resistant vegetable, prefers to grow in cooler climatic conditions, generally more suitable for coriander to grow at a temperature of 15 25, but can generally grow at a temperature of 1 5. Coriander is not very resistant to high temperatures, when the temperature in the vegetable field is above 28 for a long time, it is also more difficult to sprout, when the environmental humidity in the vegetable field is above 30, if there is no corresponding shading management method, then, this time will generally affect the growth of coriander.

Therefore, when planting coriander, it is generally carried out in March and April in spring and September in autumn, and the climatic conditions in these two seasons are generally more suitable for the germination and growth of coriander seeds. Another is to soak the coriander seeds in warm boiled water within 25 for about 24 hours, then drain the seeds, dry them slightly, and then put the seeds in the environment within 18 25 to carry out tooth promotion, when the vast majority of seeds leak white, and then carry out planting, generally this can improve the germination rate of coriander seeds. Planting coriander, when planting, should master the deep planting of coriander seeds, if the planting is too deep, <>

In this way, it will generally affect the germination of seeds, so when carrying out coriander seed planting, the planting height is generally up and down. That is, after the ground in the vegetable garden is tidied up, it is watered thoroughly before planting, and after the water seeps down, the seeds are sprinkled on the surface of the furrow, and then covered with a thin layer of fine soil, and the moisture of the soil layer is maintained. Coriander can be harvested after 50 days of planting.

It is a very rapid green plant that grows in one hundred kinds. Before planting, try to soak the seeds in cold water for 24-28 hours. The germination time of the seeds is 3-4 days, and in a few days here, you can water more and turn the soil.

And when the temperature is too huge, you can build a small shed to shade the light.

Coriander is generally best planted in mid to late April every year, and it is also possible to grow coriander in the north, because coriander does not have particularly high temperature requirements.

Planting usually begins in May and June; Coriander can also be planted in the north, it is cold-resistant, if it is in the north, it can be planted before and after Qingming, and don't sprinkle the seeds too densely, otherwise it will be easy to be very fine. Don't buy it raw, just sprinkle a thin layer of soil after sprinkling the seeds, and pay attention to water and fertilizer management for him.

Coriander is generally planted in May and June; Coriander can be grown in the north, but it must be planted in a greenhouse, because the weather in the north is relatively cold, and the coriander planted cannot live.

Coriander north is suitable for planting in several months.

In the north, coriander can be grown in July in the summer or in October in the fall. Before planting, it is necessary to prepare humus soil rich in trace elements and loose soil, and then sprinkle the selected seeds directly and evenly on the surface of the soil, covering a layer of fine soil. After waiting for half a month, the seeds will gradually sprout and grow.

Coriander cultivation method in the north.

1. Preliminary preparation.

Before growing coriander in the north, the seeds are treated simply. Pick strong and high-quality seeds, soak them in warm water at about 60 degrees Celsius for half an hour, remove them and spread them in the prepared soil.

In the process of sowing, it is necessary to pay attention to the distance between the two seeds to prevent too dense sowing from affecting the development of each plant.

Points to note for the cultivation of coriander in the north.

1. Water management.

After growing coriander in the north, there are certain requirements for watering, and dry bumper can provide unpolluted river water or pure water to keep the soil moist for a long time.

2. Fertilizer management.

After planting coriander in the north, it is necessary to provide nutritionally balanced fertilizer, which can be organic fertilizer or inorganic fertilizer, which can accelerate the growth of plants. Be careful when using fertilizers. Do not use raw fertilizer to avoid getting sick.

Normally, the climatic conditions of early spring and late autumn are more suitable for the growth of coriander, and the normal planting time of coriander is in March and April in spring and September in autumn, and now it is the hot summer, and coriander will stop growing at 30 high temperatures, so coriander can not be planted now.

Coriander has the characteristics of drought tolerance and heat tolerance, likes temperature and coolness, the seeds can germinate at about 4, the aboveground part can withstand low temperatures of -1 to 2, and the most suitable temperature for growth is 15 20; However, coriander is not resistant to high temperatures, and will grow slowly after 20 years, and will stop growing at 30 years of high temperature.

How to grow coriander.

1. Land selection and land preparation.

Coriander is a more picky place of vegetables, it has a bit strict requirements for the growth environment, in the selection of land is to pay attention to the selection of plots containing organic matter, while the soil should be more fertile and moisturizing, fertilizer retention capacity is good, it is best to drain and drain the irrigation system of good flat land. When preparing the land, plough as deep as possible, and apply the base fertilizer, which is generally farmhouse fertilizer or Trim microbial agent.

2. Sow seeds and raise seedlings.

Before sowing, the seeds should be treated, first of all, the outer layer of coriander seeds should be rubbed off, and then soaked in water for a day, then wrapped in a damp cotton cloth after fishing, and finally placed in an environment suitable for seed germination for germination, about seven to ten days later, the buds are basically complete. After the buds are all out of the seeds, you can sow the seeds, pay attention to the first watering of the ground, then the germinated seeds are scattered in a row, cover the seeds with fine soil, and finally cover a layer of film, and wait until three or four leaves grow when the film is unveiled and breathable.

3. Field management.

There will be a long period of time after sowing and watering do not need to be watered, generally have to wait until the planting and then water for the first time, after this watering, it is generally necessary to water once every seven to ten days, the early stage of coriander growth generally does not need how to water, in the middle of the year to ensure the moisture of the soil, generally the dance is watered once every seven days, and it is good to water once in more than ten days in the later stage. In the growth period of coriander, generally speaking, if the base fertilizer is applied enough, there is no need for top dressing, if it is found that less than half of the nutrients in the soil are topdressed, a little urea or phosphate fertilizer is applied.
