What should I do if the petiole of celery splits when planting celery?

Borax water should be used to spray the foliar surface or irrigate the roots to provide sufficient nitrogen fertilizer, and heat preservation measures should be used during the cultivation process to avoid wintering on land.

When planting celery, the petiole of celery is cracked, indicating that the soil is deficient in boron or less nitrogen fertilizer, and chemical fertilizer should be applied in time to supplement nutrients to the plant.

The petioles should be sprayed with disinfectant water every 5 days for 4 6 consecutive sprays, and then the roots should be sprayed with farmer taper dilution 2 3 times every 10 days.

The gap between them should be increased, so that they are as far away as possible, not particularly close, and should also water the soil more, improve the humidity of the soil, and it is also more suitable for planting, when the coarse socks of the grandchildren control the temperature, they are generally maintained at about 25, but do not water too much, and you can also spray some insecticides, so that you can effectively prevent the cracking of the petiole of Yankai.

Seedlings should be properly thinned, and reasonable watering should be carried out, soil moisture should be controlled, suitable for hail planting, and a good temperature should be controlled to strengthen the management of regulation, should pay attention to the spring blind balance of fertilization, and should be properly sprayed with some pesticides.

First of all, attention should be paid to promoting the development of the petiole root system. Reasonable watering, pay attention to a small amount of many times, with Qinshen Mountain should also be fertilized frequently, and should also be in time to top dressing. Strengthen field management, deep ploughing the soil, filial piety, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.

It is also necessary to clean up the diseased plants in time and prevent and control pests and diseases.

If you want to add nutrients to celery soon, you should also remember to water more, replenish the nutrients and water, and you can also pretend to prevent cracking.

Summary. Celery root rot mainly affects the root and stem base. Water-soaked reddish-brown spots begin to appear in the affected area, which turn dark brown or black-brown after a few days, slightly depressed, and the leaves turn yellow, developing from bottom to top, but the leaves do not fall off. The taproot is damaged and rots or dies, and the lateral roots are few.

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

Celery root rot mainly affects the root and stem base. Water-soaked reddish-brown spots begin to appear in the affected area, which turn dark brown or black-brown after a few days, slightly depressed, and the leaves turn yellow, developing from bottom to top, but the leaves do not fall off. The taproot is damaged and rots or dies, and the lateral roots are few.

The main causes of celery root rot are infected seeds or soil, water accumulation in the field, high temperature and high humidity environment, and nematodes.

When the disease has just occurred, the roots can be irrigated with 500 times of 50% carbendazim wettable powder, once every 10 days, and twice in a row.

Celery is a water-loving crop, there are many continuous stubble phenomena in production, continuous cropping obstacles are serious, and root rot is difficult to control as long as it occurs, so before there is no good disease-resistant variety, prevention should be the mainstay, reasonable seedling cultivation methods should be selected, disease-free and strong seedlings should be cultivated, and scientific and reasonable cultivation management should be carried out to achieve better control effects.

Hello, the stem at the bottom root of celery can be removed in the late growth stage. <>

But pay attention to the sealing, and protection. Everyone must control the concentration of pesticides, and you can effectively prevent pests by accompanying him a few more times. As the celery grows taller, you need to soil its roots.

Because in the process of celery production, its stalks are relatively fragile.

Hello! As the old saying in the countryside goes, let's talk about the topic of celery petiole cracking. The nutritional value of celery is relatively high, and now more and more farmers are growing this vegetable on a large scale, but it has been reported that it is easy to crack during its cultivation.

Celery petiole cracking is roughly affected by the following two situations, the first is the influence of water, in long-term drought conditions, if suddenly irrigated or rainfall will cause celery petiole cracking, at this time, because of too much water, the plant's cells swell and break the epidermis.

Try not to let celery grow in a long-term dry environment, and if there is a lot of rainfall, you should do a good job of draining it to ensure its healthy growth.

The second point is that the fertilization method is not properly managed, and the celery should be regularly supplemented with boron during the vigorous growth period, which is a trace element fertilizer, which is very beneficial to the growth of celery.

When celery begins to have signs of cracking, it is necessary to replenish nutrients in time to promote its promotion, and at the same time control the moisture when watering, and at the same time spray with disinfectants, these measures can effectively prevent the cracking of celery petioles.

At the same time, celery must be managed in all aspects from sowing to maturity, so as to ensure its vigorous growth, yield and quality are relatively high.

The first point is the seedling management of celery, which is best to use seedling trays when raising seedlings, which can not only save the number of seeds, but also reduce the incidence of pests and diseases.

This seedling raising method can be moved arbitrarily, so that the celery at the seedling stage can fully receive light. During the seedling period, it is necessary to do a good job in all aspects of management, so as to ensure that the emergence rate is higher and the quality of the plant is better.

When celery grows a few true leaves, it is best to transplant with soil, so as to ensure the survival rate and root growth is more vigorous, and watering should be carried out after the completion of the slow seedling, but the amount of watering must be controlled to prevent more water from affecting the growth of the root system.

When celery is vigorously growing, water and fertilizer management should be done well, this vegetable has very high requirements for fertilizer, and a large amount of nitrogen fertilizer should be applied in the early stage to promote its vegetative growth, but when it enters the middle stage, it is necessary to control the use of nitrogen fertilizer to prevent excessive nutrients from causing growth.

In the later stage, it is necessary to increase the use of potassium fertilizer and phosphate fertilizer, and at the same time cooperate with the use of calcium fertilizer, so as to ensure that its growth is relatively robust, so as to improve the yield and quality. If you want to water it, you can do it according to the climate and plant growth potential, and if you grow celery in a greenhouse, it is best to use a dropper, because flood irrigation can easily cause soil compaction, so that the root system can be hindered from absorbing nutrients.

Reasonable temperature can also play a good role in the growth of celery, this vegetable prefers to grow in an environment of about 20 degrees, when entering the high temperature season, the growth rate will slow down, and in serious cases, the growth will stop growing.

Therefore, when planting celery in summer, try to do a good job of shading measures to prevent burns caused by too much light. The above are some views on celery petiole cracking and management measures as an old rural saying, and teachers and vegetable farmers with different opinions can exchange feedback.

In the seedling stage of celery, it is necessary to promote the thick petiole and root development, and at the same time water reasonably, so as not to increase the humidity in the field, and after planting, it is necessary to promote the development of the root system without focus, so as to increase the drought resistance and low temperature resistance of the plant, so it is necessary to properly control the water in the early stage of planting, strengthen the cultivation, and enhance the soil permeability, so as not to affect the growth and development of the period of low temperature.

The first is to do a good job of external warmth and build a good insulation layer, the second is not to water more than twice a day to prevent too much water from frostbitten roots, and the third is to apply fertilizer every three days to make celery have sufficient nutrition.

Celery in the growth period, especially in the middle and late stages, most of the stem base together with the petiole at the same time cracking, when the temperature is low, it is easy to appear freezing symptoms, after the temperature rises, the tissue can not be recovered, prevention and control measures, according to the local climatic conditions, cultivation facilities to determine the appropriate sowing date, and in the pre-growth, mid-term to strengthen fertilizer and water management, provide sufficient nitrogen fertilizer, the cultivation process to prevent freezing, once a slight crack is found, the foliar spray borax aqueous solution, with 1 kg of borax per mu as base fertilizer, and organic fertilizer is fully mixed. Watering evenly will prevent celery from cracking.

During the whole growth period, especially in the middle and late stages of growth, white spots and even cavities often appear in the cross section, which is called hollow. Sometimes the petiole is transversely or longitudinally lobed, known as petiole cracking. Analyzing the reasons for its occurrence, there are mainly the following aspects:

1) Boron deficiency in soil is the main cause of petiole cracking.

2) Improper sowing time or low nitrogen fertilizer.

If sowing is too late, coupled with insufficient nitrogen fertilizer, the plant growth is poor, the harvest is delayed, and the low temperature and cold wave in the later stage will aggravate the hollow phenomenon.

3) The plant is frozen.

Celery prefers cold but is not hardy. When the temperature is 0, it is easy to appear freezing symptoms, and it is also easy to appear hollow after freezing.

4) The soil is too dry, which affects the absorption of boron by the roots, and it is also easy to hollow due to boron deficiency. If the soil is deficient in calcium, it is also prone to cracked and hollow petioles.

In view of the above problems, the following work needs to be done: When applying basal fertilizer, 2 should be done slowly every 667 meters

Kilograms of borax can be added, and kilograms can be applied in fields with serious boron deficiency; During the growth period, foliar spray can be carried out with 500 1000 times of Cuikang Shengli solution or borax aqueous solution. Sow seeds at the right time, and strengthen fertilizer and water management in the early and middle growth periods to provide sufficient nitrogen fertilizer. When cultivating in winter, take heat preservation measures to prevent freezing.

Evenly supply water to avoid soil dripping and wetting. Choose good breeds.

Causes and prevention of hollow cracking of petioles of celery: During the growth period of celery, especially in the middle and late stages of grinding, white spots, hollows, or transverse and longitudinal cracking of petioles often appear on the cross-section of petioles. The causes and solutions are as follows

Boron deficiency in the soil is the main cause of petiole cracking. Solution: Use kilograms of borax as base fertilizer per 667m2 of blind forest, once a slight crack is found, the available borax aqueous solution is sprayed on the foliar surface, or the roots are irrigated with borax aqueous solution.

Improper sowing period or less nitrogen fertilizer, too late sowing in open field autumn planting, coupled with insufficient nitrogen fertilizer, poor plant growth, harvest season plants can not meet the harvest standard, and in the case of delayed harvesting, it is susceptible to low temperature, cold wave, petiole softening, aggravating the hollow phenomenon. Therefore, all localities should determine the appropriate sowing date according to the local climatic conditions and cultivation facilities, and strengthen fertilizer and water management before and during the growth period to provide sufficient nitrogen fertilizer. Plants are not tolerant to severe cold, and when the temperature is 0 or below, it is easy to have freezing symptoms.

When the plant is severely frozen, the petiole tissue structure is damaged, and after the temperature rises, the tissue cannot recover, and the intercellular space increases, resulting in hollowness. Therefore, in the cultivation process, to prevent freezing, heat preservation measures should be used to avoid overwintering in the open field. Varieties of degraded celery and ordinary celery are prone to natural hybridization, so celery must be strictly isolated from other celery varieties when leaving seeds, and at the same time, in the production process of cracked seeds, some hollow plants should be prevented from being selected to retain seeds, so as not to cause the proportion of hollow plants to increase.

During the growth period of celery, especially in the middle and late stages, most of the celery is cracked at the base of the stem and the petiole at the same time, which not only affects the quality of the product, but also is very easy to be infected by pathogens, making the celery mildew.

Causes (1) Boron deficiency in soil: This is the main cause of petiole cracking.

2) Plants are frozen: celery is not tolerant to severe cold, and when the temperature is low, it is easy to appear freezing symptoms, and after the temperature rises, the tissue can not recover, resulting in hollowing or cracking.

3) Variety degradation: celery naturally crosses with common celery.

Control measures (1) Determine the appropriate sowing date according to local climatic conditions and cultivation facilities, and strengthen fertilizer and water management before and during growth to provide sufficient nitrogen fertilizer.

2) During the cultivation process, it is necessary to prevent freezing.

3) Celery must be strictly isolated from other celery varieties when leaving seeds.

4) Once a slight crack is found, spray the foliar surface with borax aqueous solution of Tita 2116, or irrigate the roots with borax aqueous solution.

5) Apply enough fully decomposed organic fertilizer, use 1 kg of borax per mu as base fertilizer, and fully mix with organic fertilizer.

6) Pay attention to even watering in management.
