If the cabbage is watered, can it still survive if it wilts?

It should work.

Cabbage is an annual or biennial herb of the Brassica genus in the cruciferous family, a biennial herb, covered with powder. Short and stout annual stems fleshy, unbranched, green or grayish-green. The basal leaves are thick, wrapped in spherical layers, oblate spherical, milky white or pale green; The biennial stem is branched and has stems and leaves.

basal leaves rounded at the apex, narrowed to very short petioles with broad wings at the base, undulating margins without distinct serrations; The upper stem leaves are ovate or oblong-ovate, and the base holds the stem; The uppermost leaf is oblong, about centimeters long and 1 centimeter wide, hugging the stem. racemes apical and axillary; The flowers are pale yellow, centimeter in diameter; peduncle 7-15 mm long; sepals erect, linearly oblong; The petals are broadly elliptic-obovate or nearly rounded, slightly absent at the apex, and the base is abruptly narrowed into claws, 5-7 mm long. The long-horned fruit is cylindrical, slightly flattened on both sides, the midrib is prominent, the beak is conical; The fruit peduncle is thick and spreads erect.

The seeds are spherical and brown. The flowering period is April, and the fruiting period is May.

Cultivation techniques. Colonization.

Select seedlings about 40 days old, 6-8 true leaves and strong seedlings, planting in the evening on cloudy or sunny days, row spacing of 55 cm, plant spacing of 35-40 cm, and planting 3000-3500 plants per mu.

Fertilizer. After planting seedlings with plastic film cultivation in early spring, due to the low temperature in spring, the general small water should be properly controlled to increase the ground temperature, and the water should not be flooded, and about 15 kg of urea should be applied with water. If there is a cold snap, 15-22 kg of ammonium sulfate per mu can be applied in advance, and irrigation can enhance the cold resistance of the plant.

As the temperature rises, entering the late stage of the rosette, increase fertilizer and water, apply Trim compound fertilizer, and combine with the application of certain plant ash. At the end of the rosette, the watering should be properly controlled, and the weeding should be cultivated in time. Farmers who transplant late should pay attention to drainage after rain to prevent root rot and leaf ball rot caused by water accumulation in the field.

Harvest. When the leaf balls are harvested at the same time, 2 outer leaves (rosette leaves) are kept at the time of harvest to protect the leaf balls, so that the surface is clean, free of pests and cracked balls. At the same time, according to the standard requirements of fresh-keeping processing exports, the size of the leaf balls is graded.

** market, depending on the demand, timely harvest and listing.

Cabbage can still survive after watering, as long as its root system does not rot and the leaves do not rot.

Hello, if your friend is in such a situation, don't water anymore, try to ventilate as much as possible, and let him slowly ease himself.

Too much watering can easily lead to stagnant water and rotten roots, causing a beating, as long as it is not particularly serious, do a good job of draining measures, and he will recover later.

Cabbage should not be watered in winter. Because the evaporation rate of water is slow in winter, watering is not allowed to prevent over-humidity, prevent water accumulation, and cause cabbage to rot and deteriorate.

Cabbage is an annual or biennial herb of the Brassica genus in the cruciferous family, a biennial herb, covered with powder. Short and stout annual stems fleshy, unbranched, green or greyish god green.

Introduction to kale

Kale is a very old vegetable, and people began to make it into a delicacy more than 4,000 years ago in ancient Greece and Rome. In Europe today, wild cabbage can still be seen growing on the barren and cold chalk barren grass flats.

Kale prefers mild, moist, and plenty of light. It is more resistant to cold and has the ability to adapt to high temperatures. The suitable temperature for growth is 15 to 20 degrees.

In the period of fleshy stem expansion, if the high temperature above 30 degrees is encountered, the flesh is easy to fibrosis. The choice of soil is not very strict, but it is suitable for planting in humus-rich clay loam or sandy loam.

Summary. If the cabbage frost damage causes the top to wither, the affected plant should be removed first and stacked aside to prevent the virus from spreading in the new plant. Then, clean up the affected area of weeds and residual leaves and make sure the soil is properly moistened.

Finally, re-sow new plants at the affected area, and pay attention to fertilizer supplementation during sowing to help the new plants recover quickly. The lack of moisture plots should be watered to replenish moisture, combined with watering and topdressing humic acid fertilizer with strong rooting to promote the growth of new leaves, and 500 600 ml of Huafu plant growth promoter can be applied per mu. For plots with good moisture, it is necessary to repeatedly cultivate and hoe to protect moisture and increase ground temperature, so as to promote the rapid development of roots and aboveground stems and leaves.

If the cabbage frost damage causes the top to wither, the affected plant should be removed first and stacked aside to prevent the virus from spreading in the new plant. Then, clean the affected area of weeds and residual leaf erections, and make sure the sail height soil is properly moistened for the rest of the day. Finally, re-sow new plants at the affected area, and pay attention to fertilizer supplementation during sowing to help the new plants recover quickly.

The lack of moisture plots should be watered to replenish moisture, combined with watering and topdressing humic acid fertilizer with strong rooting to promote the growth of new leaves, and 500 600 ml of Huafu plant growth promoter can be applied per mu. For plots with good moisture, it is necessary to repeatedly cultivate and hoe to protect moisture and increase ground temperature, so as to promote the rapid development of roots and aboveground stems and leaves. .

2.In view of the fickle weather this year, where the pole has not been demolished to restore the shed film cover, the dry dust is in a protective and semi-protected state, do not remove the shed film too early, so that the cabbage is grown under 12 20 suitable temperature conditions, and when the temperature is high, the wind can be passed around. 3.

Foliar spraying of foliar fertilizer with strong regulation, stress resistance and growth-promoting properties can be used with Bihu 5000 times liquid or brassica limb xintin lactone 3000 times liquid Wuzen spray.

Can this still survive?

This is more serious, is it all like this?

You're looking for one, take a picture of the root, this one can't be seen clearly.

It has just been planted for 2 days, and the tender places on it are frozen.

The survival rate is not very high, once it is found that the cabbage has just been planted for 2 days, and the tender part has been frost damaged, the damaged part should be removed as soon as possible to prevent the spread of the wilt virus. After the ridge is defeated, it is necessary to ensure that the whole soil is kept moist, and fertilizer is supplemented in time for the new plants that infiltrate early to help the new plants regain their vitality.

Put the more serious, from the new load, not so serious watering, fertilization, if the weather is not any problems, you can survive.

3800 4000 seedlings were used for spring cabbage, and they were covered with film and watered with planting water immediately after planting. When the average temperature of the day reaches 18 20, the leaves and roots begin to grow rapidly, at this time, fertilizer and water management should be strengthened to promote the formation of strong assimilation and absorption organs, and lay the foundation for the formation of compact leaf balls. The specific management measures are as follows:

First, the rosette stage after planting timely watering, on the basis of basal fertilizer, with the early planting water to apply a small amount of fast-acting nitrogen fertilizer, ammonium sulfate or ammonium bicarbonate 10 20 kg per mu. When the cabbage seedlings are refined, they can be sprayed with 600 times of amino acids (Jintailong) high-efficiency liquid fertilizer, which not only has a certain effect on accelerating the seedlings and enhancing the cold resistance of the seedlings, but also has a good effect on the early maturity and yield increase of cabbage. When the surface is slightly dry, carry out cultivating, and squat seedlings appropriately.

The length of the squatting seedling stage varies according to the variety, and the early-maturing small varieties have a short rosette period and a short squatting seedling period; On the contrary, it is long. Early cultivation generally squats for 10 to 15 days. When the plant grows vigorously, the leaves are obviously hung with wax powder, and the heart leaves begin to hug, the squatting seedlings should be ended in time, and then watered and topdressed to promote ball formation.

2. Bulking period After entering the balling period, the amount of water and fertilizer required for cabbage increases, and fertilizer and water management need to be strengthened. When watering, apply 20 25 kg of high nitrogen and high potassium fertilizer per mu, spray 600 times of amino acid (Jintailong) high-efficiency liquid fertilizer at the same time of watering and fertilization, and add organic silicon additives to make the sprayed liquid penetrate the waxy layer, which is conducive to leaf absorption. After that, watering is 1 time every 5 7 days, and watering is stopped 5 days before harvest to harvest at the right time.

3. Pest control The main pests of spring cabbage are cabbage worms and diamondback moths. The cabbage insects mainly eat leaves, and the bulbs are often scarred by eating, and the feces also contaminate the leaf bulbs. It can be sprayed with 5% emamectin benzoate 6 grams or fiprofen biological agent 1 gram of water 15 kg spray control, focusing on spraying leaf core.

Diamondback moth larvae infest leaves and young stems. The first instar insects eat the mesophyll, leaving a layer of epidermis, and after the third instar, the leaves are eaten into holes, and the leaf surface is reticulated or leaves are left with veins in severe cases. 15 kg of water was sprayed with 10 15 grams of avermectin per mu, and the effect was better.

After transplanting, cabbage generally takes about 20 days to take root.

1. If it still does not take root, you can apply some Woye root rooting agent.

2. After transplantation, the sedan chair should be dismantled to ensure that the water source is sufficient, and the water should be poured regularly every day to ensure that the light is sufficient.

3. It is not advisable to change the water after rooting, and the water can only be added in time after the water seepage is reduced and evaporated. Frequent water change can easily cause leaf yellow and branch wilting.

The wilting of cabbage planted in greenhouses at noon should be caused by poor respiration and wilting caused by excessive soil moisture and high greenhouse temperature. Pay attention to controlling the moisture of the greenhouse and ventilating it in time. Reduce the humidity to avoid inducing disease from the plants.

cabbage, also called fennel white; After the seedlings are divided, the temperature is required to be 15 20 during the day and 8 10 at night, and the light during the seedling dismantling period should ensure sufficient digging to promote the healthy growth of seedlings. Combined with temperature management, the jujube is washed away; Proper ventilation and moisture removal.

Vegetable rotten roots and dead seedlings are related to a number of factors, climate impact, unbalanced water management, improper fertilization management and root burning, may lead to root rot problems, water management and fertilization management should be controlled by themselves, and generally cabbage seedlings after transplanting, easy to hurt the roots and seedlings slowly, can not recover or grow new roots as soon as possible, and then will also lead to the problem of rotten roots and dead seedlings, so it is the key to promote roots after transplanting, do a good job of prevention in advance, fix the root water to pay attention to the supplement of phosphorus and calcium, watering micro root supplement calcium + energy, promote the growth of the root system, is conducive to promoting the root slow seedlings fast.

Purple cabbage black rot is harmful to leaves and bulbs, cotyledons are infected with water and then quickly die or spread to the true leaves, there are two types of true leaf infection, the pathogen invades by the water hole, causing the leaf edge to develop the disease, from the leaf edge to form a "V" shaped blight spot that expands inward, the pathogen expands downward along the veins, forming a large necrotic area or irregular yellow-brown large spot, and the leaf tissue at the edge of the lesion is light yellow.

Prevention and control methods. 1) Planting disease-resistant varieties such as Zhongqing No. 1 and No. 2.

2) 2 to 3 year rotation with non-cruciferous vegetables.

3) Collect seeds from disease-free fields or disease-free plants.

4) Seed disinfection: Add 100 ml of water to the temperature of 39 after adding ml of acetic acid and ml of zinc sulfate, soak the seeds for 20 minutes, rinse for 3 minutes, dry and sow seeds. It can also be soaked in 45% dysenammonium water agent 300 times for 15 20 minutes, rinsed and dried for sowing; Or use 50% copper wettable powder according to the weight of the seed dressing, which can prevent the occurrence of black rot at the seedling stage. In addition, 15 ml of 15 ml of pesticide antiseptic 751 fungicide can also be used to dip 200 grams of seeds, adsorb and dry in the shade; Or add a small amount of water to 10 20 grams of bleaching powder (active ingredient) per kg of seeds, mix the seeds well, and then put them in a container and seal them for 16 hours, which can effectively control the black rot fungus carried on the seeds of cruciferous vegetables.

5) Strengthen cultivation management. Sow seeds in a timely manner, do not sow too early, water reasonably, and squat seedlings at the right time; Pay attention to reducing wounds; Clean the fields in time after harvest.

6) At the beginning of the disease, spray 72% agricultural streptomycin sulfate soluble powder or neophytomycin 200 10-6 or chloramphenicol 100 10-6 or 30% green debao suspension 350 times. Discontinue the drug 5 days before harvest.
