What should I do if the coriander I planted does not sprout?

Coriander cannot be replanted, which will seriously affect the germination rate of coriander. Therefore, when sowing, the plot should ensure that at least three years without coriander has been planted.

Plant. At the same time, land preparation and disinfection should be done. Before sowing, the soil should be adequately watered and sufficient basal fertilizer should be applied.

Then the soil is broken, the softness of the soil is improved, and it is ready for sowing, which is very beneficial for the rooting and germination of the seeds. Pay attention to the weather when sowing and do not sow in the sun. After sowing, cover with soil and spray an appropriate amount of new high-fat film.

At the same time, it is covered with plastic film in strong light. Treatment at about 10 for about 3 days can effectively improve the germination rate of seeds. At the same time, in order to avoid the harm of pests and diseases, new high-lipid film and other bactericidal solutions should also be used for seed dressing and disinfection.

Even after the above treatment, coriander seeds take about two weeks to emerge. If left untreated, the germination time can be up to a month, and the germination rate will be greatly reduced. Therefore, if the soil is relatively dry when the seedlings emerge, attention should be paid to proper watering.

After the seedlings emerge, they should be watered and weeded, and when the seedlings grow to about 7-8 cm, they should be fertilized appropriately to improve the survival rate of the seedlings. Coriander is planted in furrows. The specific method of furrow sowing is to dig the land into a small gully and then sow seeds inside.

Coriander is suitable for dense planting, that is, more sowing because the coriander grown is tender and delicious.

After coriander seed treatment, the emergence time takes about ten and a half days, which is twice as fast as untreated seeds. Due to the slow emergence of coriander, if the intermediate soil is dry, it needs to be replenished with water once. The management of coriander after emergence is simple, watering and weeding.

When the seedlings grow to seven or eight centimeters tall, you can add some fertilizer while watering to speed up the growth rate and make the coriander taste fresh and tender. When the coriander grows to more than 15 centimeters, it can be harvested slowly. Before planting coriander, the seeds should be treated, spread on a flat ground, and the seed skin should be rubbed evenly with the soles of shoes or other objects that are not too hard.

Broken seeds are good for emergence and can be sown directly or soaked for germination before sowing.

First, break the shell of the coriander seed in half, then soak it in cool water until the seed has small buds. Then loosen the soil, sprinkle the soaked seeds, sprinkle a thin layer of soil on top of the seeds, and cover the soil with a layer of dry grass. After that, water every day to keep the soil moist, so that the coriander sprouts quickly, and the germination rate is more than 90%.

I think that if the coriander we grow does not sprout, we should find out the cause in time, we can loosen the soil a little bit, and then use some high-quality fertilizer to fertilize it.

Coriander has not been seedling, it may be that there is a problem with the coriander seeds, or the reason why there is no watering, you can observe for a period of time, but you can only replant if you can't do it.

Watering. Because coriander loves water and will only emerge when the temperature and humidity reach a certain level, it should be watered more.

It should be replanted, the seeds should be crushed with a rolling pin when planting, and the planting should be shallow, so that it is conducive to the rooting and germination of coriander.

It is possible that the planting time is not right. Coriander is called coriander, and we call it dampness in Jiaodong with Kaiyin, and dampness is their hometown dialect, that is, the meaning of wet and cold is not dry, so we also call coriander a dish that cannot be dried. The planting time of coriander is generally at the beginning of autumn, and it is obtained after the beginning of autumn, and there is also spring ploughing coriander, but the taste of spring ploughing coriander is very different from the taste of autumn coriander.

The bigger the coriander can be, if you don't get the coriander planted after the beginning of autumn, it will still sprout and grow and develop next spring, but the coriander that sprouts and grows in the spring has a stinky artemisia taste.

Coriander seed shell is harder, the seeds should be rubbed open before planting, and then the seeds are soaked in warm water within 50, gradually stirred with chopsticks, in order to scald the seeds with high water temperature, after the temperature is reduced, soak and soak again for 12 hours after cleaning, put the cleaned seeds on the wet rag and stretch it out, cover it with a layer of wet rag, and then place the seeds in the environment within 20 to promote teeth, and when the sprout is white and has protrusions, it can be sprinkled. Before sowing, the soles of the feet should be fertilized, and the base fertilizer is dominated by organic fertilizer, and then the crushed stones are used to level the furrow, and the seeds are evenly sown on the surface of the furrow.

Coriander must be planted with full entropy, in fact, it is planted by minimizing dry seed sowing, and watering is carried out in small plots a few days before planting to achieve the goal of improving soil moisture. Until the soil layer can be air-dried and semi-wet, sprinkle a sufficient amount of organic fertilizer as base fertilizer, but you can also use compound fertilizer as base fertilizer, and then subsoiling about 20 centimeters, flat rake fine to do flat furrow. If the soil moisture itself can be air-dried and semi-wet, it can be ploughed immediately, but some good friends who plant coriander do not pay attention to the soil moisture, the ground is small and tidy very well, and the seed sowing method or hole sowing method is also good.

If the planting time is not suitable, the seedlings may not be produced. Coriander is a type of coriander that can be grown throughout the year, but I think the best time to grow it is from September to October every year. At this time, it happens to be the favorite humid and cold climate of coriander, it is best to plant around 18 to 20 degrees, if the ambient temperature is 30 °, the coriander will not grow or grow slowly, so it is not necessary to plant in the hot summer, otherwise it will not sprout.

In the process of planting, the growth environment of vegetable seeds is too dry, or too much water, causing the seeds to rest, so that there will be very little germination.

There are two situations when the seedlings do not emerge, the first season is not right, the most suitable season for planting coriander every year is in November and December, and the second is to properly sprinkle water and soil not too dry.

It may be related to the treatment of seeds, and sometimes this situation occurs if the teeth are not done well.

It is very likely that the timing of planting is not grasped properly, and it may be caused by abnormal temperatures.

It is very likely that the coriander seeds do not emerge because the seeds have not been shelled. Nowadays, there are generally two kinds of coriander seeds on the market, which are unbroken and those that have broken their shells. If the seed has broken its shell, it will look crumbled and cracks will appear in the shell.

If the shell is not broken, the seeds are more round and smooth, and the seed coat will be more rounded. Therefore, for this kind of seeds, it is necessary to carry out shell breaking, and put the seeds into two pieces of cardboard and other plans to carry out kneading, or they can be put into gravel and kneaded. Pay attention to the amplitude, don't use too much force, cause the seed to be injured, make sure the casing is cracked.

After the coriander seeds are broken, in order to better improve the survival rate of the seeds, we also need to do a good job of tooth promotion. Wrap the seeds in a wet towel and then soak them in water for about 2 days, and you need to change the water in the fish tank once halfway. After soaking, the water is drained, and then distributed in a ventilated place to carry out tooth promotion, and the ambient temperature is always maintained at around 20 degrees during germination.

Or after the seeds are soaked, they can also be put within 10 degrees for 3 days, which can effectively improve the survival rate of seeds. At the same time, in order to prevent the damage of diseases, we should also use the new high-fat film and other sterilization solutions to carry out seed dressing, disinfection and sterilization.

Sholai cannot be cropped continuously, and heavy cropping will also seriously affect the survival rate of Shanlai. Therefore, when sowing, the land should be planted with at least three years without green plants such as carais. At the same time, it is also necessary to do a good job in ploughing, disinfection and sterilization, and the soil layer should be watered permeable before sowing, and sufficient base fertilizer should be applied.

Then the soil layer is crushed to improve the softness of the soil layer, and the furrow is prepared for sowing in advance, which is very beneficial to the rooting and germination of seeds. When sowing, pay attention to the temperature and do not carry out it in the sun. After planting, fill the soil and spray a small amount of new high-fat film, while at the same time covering the mulch film in bright conditions.

Even after the above operations, coriander seeds will take about 2 weeks after sowing before they can emerge. If it is not solved, the emergence time is likely to be as long as a month, and the survival rate will be greatly reduced. Therefore, if the soil layer is relatively dry during the seedling period, it is necessary to pay attention to moderate watering.

Subsequently, after the emergence of seedlings, it is necessary to do a good job of watering and hoeing until the seedlings grow to about 7-8 cm or less, and apply fertilizer moderately to improve the survival rate of the seedlings.

I know that when selecting seeds, it is necessary to avoid more than two years of aging, choose the appropriate sowing temperature of coriander, you can first put the coriander seeds in the refrigerator and refrigerate them, soak the broken seeds in cold water for about 12 hours, and then sow them.

Coriander is a seasoning vegetable plant that likes high humidity, so it is necessary to keep the soil moist from time to time when planting, and not to make the soil excessively dry; Try to treat the seeds of coriander before planting, such as soaking them in water for a few days, to increase its germination rate.

You can rub the seeds of coriander in a bottle or by hand, be patient, and water when the soil is dry.

1. The seed is broken.

Coriander seeds do not emerge from seedlings, which may be caused by not breaking the shell of the seeds. Nowadays, there are generally two kinds of coriander seeds on the market: unbroken and broken. If the seed has broken its shell, then the seed will look finely broken and the shell will be cracked.

If the shell is not broken, the seeds are fuller and rounder, and the seed coat will be smoother. Therefore, for this kind of seed, it is necessary to carry out the shell of the acacia accompaniment, the seed is placed in two parallel blocks of cardboard and other planes for kneading, or it can be placed in the sand and kneaded. Pay attention to the strength, do not use too much force, cause injury to the seed kernel, and ensure that the shell is broken.

2. Seed treatment.

After the coriander seeds are broken, in order to improve the germination rate of the seeds, we also need to do a good job of germination. Wrap the seeds in a damp cloth and soak them in water for about two days, and change the water once in the middle. After soaking, drain the water and spread it flat in a cool place for germination, and the temperature is kept at about 20 degrees Celsius during germination.

Or after the seeds are soaked, they can also be placed in an environment of about 10 degrees for about 3 days, which can effectively improve the germination rate of seeds. At the same time, in order to avoid the harm of pests and diseases, we should also use new high-fat film and other sterilization liquids for seed dressing and disinfection.

3. Sow seeds at the right time.

Coriander cannot be replanted, and heavy stubble will also seriously affect the germination rate of coriander. Therefore, when sowing, the plot should ensure that it has not been planted with coriander plants for at least three years. At the same time, it is necessary to do a good job of soil preparation and disinfection, and the soil should be thoroughly watered before sowing and sufficient basal fertilizer should be applied.

Then the soil is broken up to improve the softness of the soil, and the furrow is ready for sowing, which is very beneficial to the rooting and germination of the seeds. Pay attention to the weather when sowing, and do not do it when it is exposed to the sun. After sowing, cover with soil and spray an appropriate amount of new high-fat film, and cover it with mulch in a bright light environment.

4. Strengthen management.

Even after the above treatment, it takes about two weeks for coriander seeds to emerge after sowing. If left untreated, the emergence time can be as long as a month, and the germination rate will be greatly reduced. Therefore, if the soil is dry during the emergence period, then pay attention to proper watering.

Then after the emergence of seedlings, it is necessary to do a good job of watering and weeding, and wait until the seedlings grow to about 7-8 cm when they are properly fertilized to improve the survival rate of the seedlings.

As the weather turns cooler, the frost season will come in a few days, the footsteps of the day are getting closer and closer, coriander is in the season of the season, as a condiment vegetable is very popular, there are many people who are used to drinking mutton soup, the liking of coriander in their minds is self-evident, the mutton soup is put on the coriander, the taste immediately becomes fragrant and attracts people's appetite. From the beginning of autumn to the beginning of April, mutton soup is one of the delicacies that people often choose, and coriander, as an ingredient, is one of the indispensable vegetables for people to drink mutton soup. Due to the high popularity of coriander, when planting garlic, intercropping and planting coriander by using the idle stalk of the stalk indirectly improves the efficiency of garlic planting.

The coriander seeds used are not rubbed into the skin, affecting the emergence of coriander seedlings, coriander seedlings are uneven, directly sprinkled on the ridge, coriander seeds, the seed coat is thick and tough, and the absorption of water will be very slow, according to the previous planting experience, the coriander seeds that have not germinated, after the Spring Festival, the temperature rises, and they will slowly germinate one after another. However, the time to harvest coriander will be delayed a lot, which is very different from the production of garlic. Therefore, it is recommended that before sowing coriander, the coriander seeds must be rubbed into the skin, so that the seeds can fully absorb water and be evenly sown on the ridge.

The seed germination rate of coriander is low, coriander seeds, can be stored for a long time, still maintain the ability to germinate, generally placed for three years of aged coriander seeds, still has a good germination rate, farmers in the storage of coriander seeds, the use of improper methods, resulting in the seed germination rate of coriander becomes low. For example, if you are not careful, you can store it with nitrogen fertilizers for a long time.

After spraying herbicides, how do you prevent emergence? Spraying herbicides after shading is the best way, if accidentally sprayed on the stalks of coriander planting, before the coriander is unearthed, you can use a small hoe to cut a layer of soil on the stalk with coriander seeds, break the closure of the film, and reduce the impact of herbicides on coriander seeds.
