Coriander is a common vegetable, what can be done to grow coriander to achieve high quality and high

Coriander is a very tender condiment, many people not only like to eat, but also many people like to plant a few furrows in the vegetable garden, on the balcony or in the open space behind the house, but many people report that the coriander they grow not only grows badly, but also often occurs yellow leaves, red stalks, sprouts, rotten hearts, wilting, poor taste and other problems. Today, let's talk about what can be done to grow coriander to achieve high quality and high yield?

Coriander seeds are different from other seeds, they need to be broken and germinated quickly, the outer skin of coriander seeds has a layer of hard shell, the water absorption is relatively poor, and it can not be digested and absorbed to the water immediately, and it will lead to uneven seedlings without shelling. In the case of human hulling, you can put the coriander seeds into the dustpan, rub the soles of the cloth shoes, and knead the seeds into two, and you can also carry out rolling to break the seed shell into two. Generally, 1 acre of land needs about 5 kg of seeds.

The application of basal fertilizer before sowing coriander will also seriously affect the final quality and biomass of coriander, organic fertilizer should be applied to the soil layer after sufficient fertilizer, 1 mu of land 3 5 square meters or less, light fertilizer compound fertilizer slow control compound fertilizer 80kg.

In order to prevent the occurrence of diseases before and after the emergence of seedlings, the seeds can be solved well, coated with a suitable coating agent film, and then carry out sowing, coriander has a relatively loose demand for the soil environment, the general loose soil layer, convenient irrigation, not easy to seep into the field, the field that has been cultivated can be, the soil layer is not very stipulated, the organic matter content is rich and colorful, the soil layer is loose, and it has a certain ability to fix the soil and lock the water.

Autumn planting coriander can be interplanted with other overwintering crops, can also be directly done furrow sowing, or hole sowing, before sowing the land leveling, the seeds are covered with centimeter thick soil, go to suppress, water thoroughly, after sowing the autumn wind and autumn rain soil layer is wet, and do not water, generally 3 5 days, will emerge.

After the coriander seedlings emerge, grow to 4 cm high, the seedlings are congested, and the seedlings should be replenished immediately to prevent the seedlings from growing tall and weak due to blocking each other's sunlight and competing with each other for nutrients. Coriander seedlings love the wet and cold soil layer, in case of drought should be watered immediately, do a good job of irrigation system software, in case of waterlogging, can remove precipitation as soon as possible, if the planting of coriander market time, catch up with the New Year's Day and the Spring Festival market, the coriander sown after the cold dew solar term, need to build a simple plastic shed insulation to promote growth.

In order to grow coriander robust and fat, proper spraying of foliar fertilizer is one of the most favorable adjustment measures, coriander seedlings emerge for about 10 12 days, you can use urea aqueous solution + potassium dihydrogen phosphate aqueous solution + 3000 times liquid brassinolide, sprayed every 7 10 days. Coriander grows fast and well, and has a strong flavor.

It is necessary to pay attention to the protection of coriander roots, and to pay attention to the way of crop rotation, but also to pay attention to watering and fertilization, so that high yields can be obtained and yields can be increased.

It is necessary to choose the right variety, be sure to pay attention to the soil, pay attention to the density of planting, and the seeds need to be crushed when planting.

Coriander is a vegetable that is mainly eaten by stems and leaves, so it is of great significance to prevent and control diseases of stems and leaves. When the leaves appear yellowish-brown and have rot spots, it may be a fungal infection.

To spray mancozeb, methyl tobuzin and other agents in time, once a week, 2 times is almost enough. In principle, the water management of coriander during the growth period maintains sufficient water and fertilizer, so the top dressing is not affected by drought and moisture at the seedling stage, so it is understood that the planting management of coriander should be based on the soil fertility of the top dressing, and the fertilization and water should be combined with Kaiqiao to apply urea or nitrogen and potassium fertilizer, and the amount of fertilizer is generally about 15 catties at a time.

<> coriander is cultivated more, people have the habit of eating coriander, and its special smell and a certain amount of consumption have become an important vegetable in each low, and can be sown in rows according to market demand. However, it does not mean that extensive cultivation can lead to high yields and bumper harvests. Coriander is a warm-loving and shade-tolerant crop, which can survive in low temperature and high temperature environments, but the most suitable temperature for its growth and development is still 17 20, and to achieve high yield, it is necessary to first choose a suitable soil and pay attention to temperature and humidity regulation and control.

In order to improve the emergence rate of coriander, we can promote seed germination. It is to soak the selected seeds in clean water for about 1 day, remove them and place them in a damp cloth or towel, spray them with water every day, and wait until most of the seeds are exposed, and then you can sow them. Coriander at the seedling stage, slow growth, adequate fertilizer and water management is very necessary, can be used with high nitrogen compound fertilizer to help grow, do not use hormones to pull seedlings, transport ears that will be counterproductive, resulting in coriander slender and long, low yield, poor quality, not resistant to storage and transportation, thereby reducing the value of the commodity.

The sowing period of coriander planted in summer is generally not very strict, and it is generally sown in June and July, which can be determined according to the stubble and the time of preparation. Adopt strip sowing or hole sowing, hole sowing and strip sowing distance is generally 20x25 centi, 4 to 5 grains per sowing, 1000 to 1500 grams per mu.

When planting coriander, the requirements for the conditions are also very strict, so when planting, we should still ensure the light time of two hours of beam digging, and at the same time, when planting, we should also pay attention to insect pests, so as to increase the amount of oak cores.

It should be watered and fertilized more, and at the same time, it should be fully illuminated by the sun, so that it can be better, and the surrounding trembling weeds should also be cleaned when the eggplant is usually poor.

In normal times, you should water more and fertilize more, and be sure to ensure that the sun is shining, because only in this way can you improve the material.

1 planting time. Coriander is a vegetable that is sensitive to high temperatures and can be grown in all seasons except summer. If coriander is grown at the right temperature and environment, it will quickly grow new roots.

So coriander is generally planted in the fall. The coriander planted at this time has a good appearance, few diseases, and good quality. Among them, the best time is September.

Of course, it can also be done at the same time when the cabbage is planted in August.

2. Variety selection. It is best to choose small-leaved varieties, because small-leaved varieties have small leaves, but they are cold-resistant, fragrant, and of high quality. Whether you eat it yourself or sell it, it's the best choice.

Moreover, the seeds should be selected and the oranges are fresh and full, so that the germination rate will be relatively high. Choose the seed bridge with good quality, strong aroma and no obvious mechanical damage on the surface. Then soak the seeds in warm water at 55 for 15-30 minutes.

Then peel off the coriander seed coat and soak it in water for about 20-14 hours. After the seeds have swelled, the seedlings can be removed.

3. Sowing. There are strict requirements for the sowing depth of coriander. The roots of coriander are shallow, sowing too deep, the soil is poorly permeable, and it is difficult to emerge.

Too shallow and easy to pour. The suitable planting depth of coriander is generally between. Some friends are not good at grasping the depth when sowing, which will affect the quality of coriander.

The easiest way to plant in your own small garden is to water it, sprinkle the seeds on it, and finally sweep it with a broom and cover it with a thin layer of soil. Before birth, unless the soil is particularly dry, it cannot be watered, after birth. Re-water.

4. The diseases of coriander are generally less, mainly seedling wilting disease, virus disease at the adult stage, anthracnose and spot blight, as long as the drug is used after the coriander emerges, it can be prevented and controlled. The main pest is aphids, which are very common in hot and arid conditions. Generally, inhaling coriander leaf juice will lead to reduced yield.

It can be sprayed with 10% imidacloprid 800 times, 1 time in 7 days, 2-3 times in a row.

5. When the coriander grows to 30-35 cm, it can be harvested. It is advisable to water again before harvesting, which will help pull the cilantro out of the soil. It is advisable to uproot it.

In this way, it can be stored for a long time and can stay fresh for a long time. If dry, you can spray a small amount of water.

When planting, a bucket of Qing is determined to choose the soil is more fertile and wide land, and in the fertilization must use farmhouse fertilizer, do not use the fertilizer bought outside, but also often water the plant bend, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then be sure to spray insecticides in time.

When planting, we should choose excellent varieties, we should loosen the soil in time, maintain the permeability of the soil, water and fertilize in time, strengthen the management of water and fertilizer, and we should keep the right temperature for Kuantong, spray some pesticides regularly, and remove insect pests in time.

Pay attention to the nutrition of the land, pay attention to the weather, pay attention to the planting method, pay attention to the varieties of Hunan vegetables, and pay attention to watering.

In our rural area, every family will grow a small cusp of coriander, and the family will eat it for a winter and a half spring. Coriander is generally sown between September and October. Sprinkle some farm manure first, then turn the ground over.

The coriander likes to be cold and not resistant to high temperatures, and the growth is slow when it is more than 20, and it stops growing when it exceeds 30. In the hot summer, coriander is relatively high due to the difficulty of planting.

<> coriander seeds are hard, when planting coriander, we generally rub it open, make the seeds into two halves to talk about the core bush, and then sow seeds, when the coriander seeds are sown, then should also be covered with a layer of about 1 cm or so of fine soil, and then watered permeable, before planting it is recommended to clean up the soil of their own small vegetable garden and loose, if it is dry, it is recommended to water a little water first, and then dry for two or three days, and wait until a suitable moist area when the seeds can be sown directly. If it's wet.

Relatively speaking, coriander prefers cold temperatures, and if the temperature is too high, it is not easy to emerge. If you plant coriander for a long time, except for the above-mentioned ones covered with sheltering objects, or planted in a shady place, and planted in the open air, there will only be few seedlings and poor quality. Method 1:

Choose the right variety. There is a good saying: choice is greater than effort!

The same is true for planting coriander in summer, because coriander is afraid of heat and cold, so it is best to choose some varieties of coriander such as four seasons coriander and Beijing coriander. These cherry varieties are of good quality and heat tolerant.

If you want to plant a large area, you need to cultivate the land. Or you can look for the planting related to the Dan**, and there are articles to learn about it. Because it is a large number of plants, it requires a certain amount of technology, as well as various technologies such as temperature and humidity.

Coriander is hardy and heat-resistant, prefers a cold environment, and is generally most suitable for growth under 12-18 conditions, while growth is stunted for more than 30 years. Moreover, coriander is a long-day plant, and after a certain low temperature vernalization, the sunshine duration exceeds 12 hours, and it is easy to sprout and flower.

After planting, it can be topdressed according to the situation, and the topdressing is mainly fast-acting nitrogen fertilizer, and the number of watering is increased when the temperature is high; In the later stage, coriander needs potassium, and potassium dihydrogen phosphate can be sprayed to improve the value of coriander. However, it should be noted that the water should not accumulate after watering or rain in the field, and it should be changed slowly, and good permeability should be maintained. It can also be managed by covering the sun during the day and uncovering it at night.

The management of moisture and temperature must be done well, so that the coriander will have a high yield, and at the same time it is very green, and fertilizer should be added in time to achieve high yield.

First of all, it is necessary to select high-quality varieties, select the land with strong applicability, remove pests in the limb period, implement fertilizer fertilization, regular watering, and good sandy loam soil with high terrain and rich organic matter, loose soil and good water and fertilizer retention.

Prepare the land to make fertilizer.

Choose the blind land with shading facilities as the cultivation land, you can also cover the coriander with straw after sowing, remove the straw after taking the seedlings, build a small flat shed with a height of 60 70 cm, and cover it with a shade net. It is better to use sandy loam soil with high terrain, rich in organic matter, loose soil, and good water and fertilizer retention.

First of all, it is necessary to choose high-quality varieties, choose land with strong applicability, regularly remove pests, implement top dressing and fertilization, and water regularly.

Coriander management method:

1. Selection of planting soil.

The soil planted in the soil must have a certain amount of wetting and fertility, and the soil itself must have a good drainage system, otherwise it is easy to cause root rot in the rainy season. Before planting coriander, the soil must be cultivated. When cultivating the soil, it is necessary to pay attention to digging deeper, so that he can retain more water, which is conducive to later development.

For cultivated land with coriander, a neutral pH is best.

2. Sowing and seedling management.

Before planting coriander, you can treat the seeds, peel off the outer skin of the coriander, and then soak them in warm water for about a day. Remove, wrap in a damp cotton cloth and drain. At this time, put it at a more suitable temperature.

In about seven to ten days or so, all the buds will appear, and then it is ready to be planted. Leave a nice distance for each seed to develop better later. After planting, cover with fine soil, and then cover a layer of film, which has the effect of moisturizing and heat preservation, and after growing three or four leaves, remove the film to facilitate breathing.

3. Water and fertilizer management.

When planting, it needs to be watered again. You don't need to water much upfront. Generally, water once every ten days.

In the medium term, when the coriander grows, it needs to be watered every five to six days. In terms of fertilization, it is also necessary to apply fertilizer once when the land is cleared, once again when planting, and again when harvesting. Coriander does not have particularly high requirements for fertilizer moisture, so it is okay to ensure the basics.

4.Pest control.

In the middle of cilantro growth, insects suck coriander. Therefore, in order to guarantee its integrity, it is necessary to observe the invasion of insects. Before an insect invasion, be prepared to control pests.

You can spray it with ordinary potion first, usually once every half a month. If it is a pest, it must be sprayed every five or six days, and different potions can be selected according to different pests. Young coriander roots are often eaten by some insects in the field.

Therefore, we must be careful when farming.

Coriander is actually very easy to manage, as long as we do a good job in the management of coriander in various periods, it will actually play a great role in the growth of coriander.
