If you plant an acre of Chinese cabbage, how to deal with rotten bumps?

Chinese cabbage is also known as soft rot, it is recommended to use copper acetate, gramidan wettable powder and 500 million fluorescent Pseudomonas fluorescent mixed with soil for sprinkling.

Unplug it in time. As long as there are rotten bumps in the Chinese cabbage in an acre of land, it must be pulled out in time, otherwise it may affect the healthy growth of other cabbage.

Sterilization treatment. Cabbage has a rotten pimple, which is a bacterial disease that needs to be sterilized with the right amount of formula.

That's probably because the cabbage is too densely planted. You should pull one after another and then keep the cabbage ventilated.

Chinese cabbage root pimples, that is, root swelling disease. In recent years, root swelling disease has occurred from time to time, which has a great impact on the quality and yield of Chinese cabbage. The symptoms are damage at the seedling stage, and the seedlings die in severe cases.

Cabbage plants wilt and grow poorly. The main and lateral roots are round or oblong tumors of different sizes, and the surface of the tumor is smooth at first, and then it becomes rough and then cracks. The symptoms of the aboveground plant are not obvious in the early stage of the disease, and then the growth is slow and dwarfing, the basal leaves wilt at noon, return to normal in the morning and evening, and the leaves turn yellow until they wilt and die.

Chinese cabbage root swelling is a soil fungus disease, which mostly occurs in cruciferous vegetables. Chinese cabbage root swelling disease is very difficult, after the disease occurs, the pathogen directly hinders the delivery of nutrients to the aboveground part of the plant, the vegetables grow to the middle stage, and the root rot appears in the early stage, resulting in a large area of death of a large area of vegetables, bringing huge losses to the farmers' economy.

Due to the serious problem of heavy cropping in recent years, the accumulation of fungi is large, and Chinese cabbage root swelling is more likely to occur. Prevention and control methods:

Severely diseased areas should be rotated with non-cruciferous crops for more than 6 years, and weeds should be eradicated. After harvesting, the root of the disease is completely removed and destroyed in a centralized manner.

Chinese cabbage is cultivated in low-lying land or poorly drained plots, and it is necessary to cultivate it in the form of high furrows. At the same time, apply lime appropriately, adjust the acidic soil to slightly alkaline, and sprinkle 75-100 kg of lime per mu before sowing to disinfect it.

Chinese cabbage is a cruciferous vegetable, which is cultivated in a large area in our Shandong region, and there are many varieties, such as Jiaozhou Chinese cabbage. However, in recent years, with the perennial continuous cropping, the root diseases of Chinese cabbage have become increasingly aggravated, mainly root nematodes and root swelling diseases. The symptoms of both diseases cause the roots of Chinese cabbage to swell, which is difficult to distinguish, and if not distinguished, it will lead to medication errors and delays.

One, the difference between the two is:

1. Root swelling disease is a fungal disease, the roots of the damaged Chinese cabbage are swollen, the big ones are the size of a fist, and the small ones are the size of corn kernels, which are colon-shaped. The onset of Chinese cabbage at the seedling stage is more common. Root swelling disease mainly harms cruciferous vegetables such as radish, rape, and cabbage.

2. Root nematode disease is a pest, which is caused by nematodes harming the roots, mainly forming some small nodules on the fine roots, which are in the shape of chicken claws. In addition to cruciferous vegetables, root nematodes also harm Solanaceae crops.

Second, prevention and control methods.

1. For the prevention and control of root nematodes.

It is best to rotate crops with grasses for 3 to 4 years. 

Then there is freezing, deep ploughing of the land in autumn can eliminate some overwintering pests.

If diseased plants are found in the field, or after harvesting, the diseased residues will be burned together to reduce the source of disease. Strengthen field management, promote plant growth, improve disease resistance, and reduce disease loss.

Then there are field medicines, such as chlorinated bitter smoked soil, thiazolphos and other root irrigation or soil treatment.

2. For the prevention and treatment of root swelling disease

Chinese cabbage root swelling is difficult to prevent.

Choose varieties with strong disease resistance, pay attention to field water management, and do not accumulate water for a long time. Use well-decomposed manure or compost in the field.

In crop rotation, it is best not to sow cruciferous vegetables in plots with severe root swelling, as this bacterium can survive in the soil for more than ten years.

Root swelling bacteria like acidic soil, and can be soiled with quicklime or plant ash to adjust soil pH.

Chinese cabbage seeds can be blanched in warm water, or soaked in potassium permanganate, or soaked in chlorothalonil.

Drug prevention and control can be used for cyanoglurazole, carbendazim, chlorothalonil, fluridine and other root irrigation. 

In short, if there are pimples, swelling and other symptoms on the root of Chinese cabbage, it is necessary to distinguish what is the cause, and different reasons should be taken with different prevention and control methods, and the medicine must not be used indiscriminately, so as to prevent delaying the condition and causing greater losses.

The condition of cabbage rot is because the outer leaves of the vegetable balls are good, but the heart leaves rot from the edge to the inside, causing sandwich rot Disease conditions Chinese cabbage soft rot is a bacterial disease, the pathogen of which is the parenchyma Owenella that invades from the wound of the vegetable plant. Therefore, the occurrence of soft rot is related to the number of wounds on the plant. The resistance of Chinese cabbage to the disease was reduced in the hearting stage, and soft rot occurred at low temperature in the rain.

Photosynthesis is weak, respiration is enhanced, growth is very weak, Chinese cabbage is a moist vegetable, the whole growth period needs moist soil conditions, especially Chinese cabbage can not lack water in the rosette stage and carpet stage. Cabbage soft rot, the virus is usually contracted through seeds and soil. To eradicate the disease, prevention comes first, and it is better to buy seeds when selecting seeds.

Seed companies do not harvest seeds and land continuously, and it is better to plant cabbage every other year. For Chinese cabbage root rot, we can choose high-terrain, well-drained plots or ridges to plant to prevent water accumulation in the field. In the early stage, it is necessary to properly shade the high temperature, and pay attention to the cultivation in the later stage to maintain proper soil moisture.

If soft rot is found, avoid continuous cropping. Soft rot is also a soil-borne disease. Bacteria can overwinter in the soil and then continue to harm bok choy the following year.

The rot at the base of the petiole is invaded from the wound at the base of the vegetable side, forming a water-infiltrated area, gradually expanding and softening, turning to a light gray-brown color, and finally the leaves are completely rotten. When most of the leaves are infected, the entire plant collapses. The whole plant wilts and rots the pathogen directly invades from the roots of the seedlings, and the whole plant grows slowly and the outer leaves wilt.

During the rosette stage, vegetable plants can be seen withering at noon on a sunny day, but sooner or later they will recover. The outer leaves of the diseased plant lie flat on the ground, the heart or bulb is exposed, and the pith tissue at the petiole or rhizome ulcerates, which collapses with the slightest touch. If crop rotation conditions are not available, fungicidal pesticides should be sprayed before sowing.

Don't use urea blindly. Urea is the solid fertilizer with the most nitrogen content. Although Chinese cabbage has high requirements for soil moisture, it cannot withstand frequent rainy weather, and can be regarded as a crop that is afraid of waterlogging.

It is further extended to the high soil moisture and even the accumulation of water in the garden, which causes the root soil of Chinese cabbage to be impermeable, thus causing the phenomenon of root rot. The amount of irrigation should not be too large.

Crop rotation of wheat and gramineae in severe disease fields can reduce the occurrence of diseases, change the planting method, change the traditional flat furrow planting to ridge planting, the best controller, in the early stage of core cover collection, you can choose the agent Chunleimycin, Zhongshengmycin, copper hydroxide suspension, copper sulfate, basic copper sulfate, chlorobromoisocyanuric acid, etc. For patients with more serious conditions, root irrigation can be carried out, such as high-efficiency and low-cost chlorbromoisocyanurate copper sulfate, etc., large-scale irrigation or drip irrigation can also be used, hoping to help everyone. At the same time, it is necessary to pay close attention to the weather forecast to prevent diseases due to excessive humidity and temperature.

If you can't get a good grasp of the amount of irrigation, you can water the odd ditch first, and then the even ditch after a few days. If the disease is mild, drugs such as prixclax, dimephalen, or colul may be used early in the disease. These chemicals can be used by root irrigation or by spraying the stem base of the plant.

When planting Chinese cabbage, water more and control its growth temperature to 20, so that the cabbage will be in good condition and better quality.

You can remove the rotten bumps on the Chinese cabbage, or you must pay attention to more topdressing and watering when planting, and you can plant Chinese cabbage with a relatively high appearance.

can only be disposed of at a low price, and such cabbage will definitely not be able to continue to be sold at the original price, and it will not be sold.

When planting Chinese cabbage, it is good on the outside but rotten on the inside, because the cabbage lacks calcium. Cabbage is prone to symptoms, and if it is rotten, it must be supplemented with fertilizer. In the process of planting, it is necessary to focus on supplementing calcium to Chinese cabbage, and you can also sprinkle some lime in the soil.

Only by making the soil fertile can cabbage grow better and better. Don't think that there will be nothing wrong when the cabbage grows, if you don't fertilize it regularly, there is no way to make the cabbage harvest. Be sure to spray calcium fertilizer from top to bottom before wrapping the core, so that it can be well absorbed.

The most common disease of Chinese cabbage is downy mildew, which occurs from flowering to fruiting. When you notice some small spots on the Chinese cabbage, don't be careless at this time. Diseased leaves will appear like white frost and will slowly wilt.

When the temperature is relatively high, cabbage will grow this disease, and you can choose to buy some sprays for prevention and control. The disease of spraying cabbage several times in a row can be very good**, and you don't have to worry about not being able to harvest. <>

If you want to grow this cabbage all year round, you have to change the planting area every season. It is necessary to balance the trace elements in the soil so as not to have a certain impact on the crops. After choosing the soil, be sure to choose some organic fertilizers that are not chemically active.

Although the use of fertilizer can help cabbage grow faster, it does not have the premise of disease control. <>

In general, when planting cabbage, it is not only necessary to carry out timely top dressing, but also to allow the fertilizer to be well absorbed by the roots. If it can be replenished in a short period of time, this method of fertilization is still very good. It must not be allowed to rot or become seriously ill.

The applied fertilizer must allow the cabbage to be well absorbed before it can be sold at a good price. If it rains, the cabbage must not be exposed, and it must be protected in time.

It may be that the cabbage lacks calcium, or it may be that it has soft rot, so we must pay attention to spraying more pesticides to prevent insect pests in time, and then clean up the stagnant water.

It may be because of the soft rot of cabbage, which has been eaten by insects and infected with some bacteria before the cabbage is wrapped.

The first point may be that survival must be paid attention to, and the second point is that there may be decay or some special germs in it, and the drug should be dispersed in time.

It may be that you have soft rot, and after you have this disease, some rot will occur in the heart of the dish, and the appearance will be better.

It may be that the cabbage is deficient in calcium, and the balanced use of nutrients is not noticed in the process of fertilization, and such a situation eventually appears.

I think it's probably too hot inside, so that's why we can spray some pesticides to protect it.

Pesticides that can rot should be used, and the effect of this pesticide is generally very good, which can prevent the mortality of bok choy.

Chitin can be used, and this medicine can be diluted and sprayed to solve this disease very well, but it is still necessary to choose according to the actual situation.

It can be used, streptomycin sulfate soluble powder, diluted vinegar, vegetable fengling, bacterial poisoning, and agricultural resistance 751, etc., can play a good role.

At this time, you can choose some fungicides, and then you can also choose the corresponding chemical pesticides, for example, you can choose the copper of Chunlei Quinoline, and try to choose a concentration of 36%.
