What s going on with the green onion dying during the growth process

In order to prevent the roots from rotting and dying due to the soaking of rain for several days, the root system can only tolerate light and thin fertilizer. The most afraid of extreme drought in the soil will cause root dehydration, and it is necessary to irrigate or water in time: the most afraid of high temperature and scorching sun in summer over 35 degrees There are five kinds of green onions in the growth process, which will lead to difficulty in root extension and affect the growth of roots.

The above are the five reasons why "the green onion dies during the growth process", please cultivate it at a higher level, loosen the soil between the rows after heavy rain (it can indirectly improve the cracking and ventilation of the onion root soil), and if you care about it, you should pull a shade net to cover it with semi-shade. The most afraid of soil compaction, otherwise it cannot be reversed. I am most afraid of soil waterlogging.

Most afraid of fertilization is too thick, do not apply thick manure and urine, do not directly apply fertilizer particles into the rhizome, in case of high temperature, it will be suffocated and rotten roots due to compaction and impermeability.

There are five kinds of green onions that are most feared during the growth process:

I am most afraid of the high temperature and scorching sun of more than 35 degrees in summer, and if you care about it, you have to pull a shade net to cover it.

If you are most afraid of the soil being waterlogged, please cultivate it at a higher level to prevent the roots from rotting and dying due to the soaking of rain for days.

The most feared is that the root system will be dehydrated due to extreme soil drought, and it is necessary to irrigate or water it in time, otherwise it cannot be reversed.

Most afraid of fertilization is too thick, do not apply thick manure and urine, do not directly apply fertilizer particles into the rhizome, the root system can only tolerate light and thin fertilizer.

The most afraid of soil compaction, which will lead to difficulty in extending the roots and affecting the growth of the roots, in case of high temperature, it will be suffocated due to the compaction and suffocating the roots, and the soil should be loosened between the rows after heavy rain (which can indirectly improve the cracking and ventilation of the onion root soil).

Planting shallots in winter is not frozen to death, green onions are a very cold-tolerant plant, even in the climate of nine cold days, it will not be frozen to death, and can grow normally. Although it is cold-resistant, it is very afraid of typhoid heat, so many people usually store shallots outdoors, if they are placed indoors, especially in winter, they are easy to rot.

Green onions will not freeze to death in winter, because green onions grown in a cold environment for a long time have strong cold tolerance and can survive in winter, and when maintaining green onions in winter, they need to provide nutritious and balanced fertilizer to maintain the growth of plants, and they can also be watered with pollution-free water for green onions to avoid the death of plants due to lack of water. When caring for green onions in winter, it is necessary to provide them with nutrient-rich fertilizers. It is best to provide well-rotted farm fertilizer or urea for green onions at the beginning of winter, so that the plants can store enough nutrients, and after the winter is complete, you can add compound fertilizers rich in nitrogen, phosphorus and potassium elements to the soil to maintain the growth of the plants.

<> shallots are not afraid of freezing in winter, that is to say, the onions are not afraid of cold, but they are afraid of moving it back and forth.

If a green onion stays still in the ground, you'll get a green forest. Like a meadow.

Generally, it will not die, it will grow forever, but if no one takes care of it, the green onion will grow thinner and thinner, and the longer and thinner it will be, and finally it will become a pot of weeds, which is similar to the wild onion.

The shallots in Sui County can be cut like leeks, and after cutting, the shallots will grow like leeks.

Generally, China's native green onion is dug up with the white onion root, pinch off its leaves, and eat the green onion white, but the green onion in Sui County is cut and sold like a leek, and new green onions grow in the green onion tube after cutting, which can be cut stubble after stubble like leeks.

This is a special variety of green onions, commonly known as perennial green onions, the scientific name of German all-green chives, German all-green chives plant erection, plant height 45-50 cm, slender leaves, dark green leaf color, tubular leaf diameter of 3 5 mm, strong tillering force.

Compared with ordinary green onions, its fragrance is stronger, the root system is developed, the vitality is strong, it can grow for more than 2 years when it is planted, it can be harvested like a leek, it can harvest 7 stubbles a year, and the annual yield per mu reaches 1500 kg.

Extended information: Due to the small diameter of the German chives leaves and the full thick green, the processed products are "full and green", with uniform particles and bright color; The dehydrated products processed from local chives first remove a long section of protein, and then the processed products need to be manually sorted according to different colors, which is labor-intensive and material-intensive. Hope!

It will not be in winter, if a loose soil has been growing, it will slowly hurt or become something, generally after some damp blood or grow very tall, if there is no blood congestion, it will generally wither.

It will slowly wither when it reaches its age, but it will live a long time, and no living thing will not die.

Don't be curious, Satoshi can't freeze to death, and if a green onion is allowed to grow in the soil, it will become a dense green forest and not die.

If you're really curious, experiment with it on your own land or in a pot.

The longer the planted green onion grows, the more wilted, it may be that the planting soil is compacted, resulting in the dry drying of the roots of the plant, or it may be that the roots of the green onion are soaked in water and rot due to too frequent watering, or it may be that the temperature of the core of the environment is too low, which is not suitable for the growth of the green onion, resulting in the phenomenon of frostbite death of the plant, and the green onion is a light-loving plant, which will wither and die in a dark environment.

1. Soil compaction

The growing green onions become, the wilts become, which may be due to the hardening of the planting soil. Because the roots of green onions are thin and short, if the soil is clumped, the roots of the green onion will not be able to absorb nutrients normally, so the longer it grows, the more wilted. In the process of curing, it is necessary to loosen the soil for the onion every other month.

2. Water accumulation in the roots

Onion has the characteristics of liking water and being afraid of waterlogging, if in the process of maintenance, frequently provide water for the onion, it will lead to water accumulation and rot at the root of the plant, and the longer the plant grows, the more wilted, so in the later stage of maintenance of the onion, it is necessary to regularly observe the dryness of the soil, and when the soil is dry, it can provide water for the onion and soak all the soil.

3. The temperature is too low

Onions are suitable for growing in a warmer environment, if the planting environment temperature is too low, it will lead to frostbite on the green onions, the longer the more wilted, so in the process of raising ambush and protection, you need to take warm measures for the green onions, it is best to use bamboo strips and plastic film to build a greenhouse for it, to keep the plant growth environment warm.

4. Lack of light

Green onions are inseparable from light in the process of growth, planting chives in a dark and dark environment will cause the plant to grow more and more wilted, unable to grow normally, so in the process of maintenance, it is necessary to put the chives in a sunny environment, so that the plants can photosynthesize normally and grow more vigorously.

1. Land selection and land preparation: use semi-shady and ventilated plots to carry out ploughing and fertilization. 2. Prepare the seeds:

Choose heat-tolerant varieties or buy green onion seedlings outright. 3. Treat the seeds: soak them in clean water to absorb water, and then wrap them in a damp cloth to promote germination.

4. Sowing: Directly sow the green onion seeds into the soil, and shade them with a shade net after planting.

1. Land preparation and land selection

Planting onions in the summer high temperature period, you should choose a good location in advance, choose a semi-shaded, ventilated, well-drained plot, determine the field, plough the soil in advance, and apply well-rotted organic fertilizer, which is conducive to the healthy growth of onion seedlings.

2. Prepare the seeds:

Most of the onions are planted by sowing methods, the temperature is high in summer, it is necessary to choose varieties with good heat resistance, which is conducive to germination and growth after sowing, if you feel that sowing is troublesome, you can directly buy onion seedlings, and then plant them in batches.

3. Treat the seeds

Green onion seeds should be processed in advance, first soak them in clean water to clean, filter out the bad seeds, then put the remaining seeds into warm water at 50 degrees Celsius, soak while stirring, take them out after 15 minutes, and finally wrap the green onion seeds with a damp cloth.

4. Carry out sowing

After the soil is finished, the ditch is opened, the green onion seeds are evenly sown into the soil, and a certain spacing is maintained, and the green onion should be properly shaded after planting, and a layer of shade net should be pulled, and regular watering should be kept moist, but the rainy season should pay attention to drainage to avoid green onion seedlings rotting roots.

Hello, it is a pleasure to serve you with the following answers: There are many causes of onion death, the most common of which are lack of water, pests and diseases, over-fertilization, etc. Workaround:

1.Strengthen water management: Onion heads need sufficient water, and irrigation can be increased appropriately to ensure the normal growth of plants.

2.Pest control: Timely weeding and removal of pests and diseases can restore the health of plants.

3.Proper fertilization: Applying the right amount of organic fertilizer can improve the plant's disease resistance to prevent the occurrence of pests and diseases.

Personal Tips:1Strengthen the management of plants, timely weeding, removal of pests and diseases, in order to ensure the normal growth of plants.

2.Applying the right amount of organic fertilizer can improve the disease resistance of plants to prevent the occurrence of pests and diseases. 3.

Strengthen water management and replenish water in time to ensure the normal growth of plants.

The air humidity is high, which inhibits transpiration. As a result, the absorption of the root system is reduced, and the nutrients brought to the leaves by absorbing water - nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, zinc and other fertilizer elements - are also greatly reduced. Long-term lack of fertilizer elements will also cause dead plants, and exacerbate the occurrence of diseases, resulting in disease and dead plants.

There are many continuous rainy weather, too much water accumulation leads to high soil humidity and high air humidity, which inhibits the transpiration of green onions, resulting in the weakening of the water absorption ability of the root system, the suffocation of the roots, and the reduction of nutrients added to the leaves, so that the long-term lack of fertilizer will lead to the aggravation of pests and diseases, resulting in the death of plants.

Due to years of continuous planting, soil-borne diseases are serious, resulting in soft rot wilt, root rot, and excessive soil moisture, which aggravates the occurrence of diseases and leads to dead plants. Thirdly, summer and autumn are also the seasons of serious insect infestation, and now it is forbidden to burn straw, and a large number of insect eggs are left in the field, and the summer and autumn are vigorous in reproduction, biting the plants. The disease is severe.

Due to years of continuous cropping, soil-borne diseases are serious, resulting in a large number of soft rot, wilt and root rot. In addition, the excessive soil moisture aggravates the damage of diseases, so many plants die from diseases.

When encountering the occurrence of the phenomenon of dead green onions, it is necessary to smell and look twice. If you can smell a foul smell, you can determine whether it is a fungal or bacterial disease, so you can buy pesticides for similar diseases, and timely treat the green onions. Green onion gray mold is a common and difficult fungal disease to control in open field crops, which is caused by Botrytis cinerea.

The growth temperature of the pathogen is 20 30, and if the humidity is maintained above 90% in this temperature range, the incidence of gray mold will be high.

Summer and autumn are the periods of serious occurrence of insect infestations, and field management must be strengthened. If a pest is found, it is necessary to spray insecticides to control the pest. Spraying pesticides on underground pests is not effective, and can be combined with fertilization and irrigation to irrigate the roots. If fungicides are added when the roots are irrigated, the effect will be better.

will die, in fact, the main reason is that the season is watering, so when you water too much, you will die all of a sudden, and then you usually don't pay attention to renovation, so you die.

In fact, it is very likely that the temperature is too high, so there will be death. So control the temperature and water.

Because the green onions in summer are bitten by insects, and the temperature is particularly high, there is no timely ventilation, so they will die.

This is because the plants are infected with germs or because they lack nutrients, so they die.

It is likely to be caused by a lack of water or nutrients, or it may be caused by a virus or the activity of the green onion itself is not high enough and the lack of light.
