    When plowing the field, it is necessary to add humic acid. Apply 80 kg to 100 kg per mu. This can achieve a preventive effect.

    It can also be combined with insect and disease control, add mildew water agent, and eat less nitrogen fertilizer, need to increase phosphorus, potassium, magnesium and other fertilizers. Usually pay attention to the fertilization of the land, as well as loosening the soil. And it is also necessary to avoid excessive glue, because it is also easy to cause cabbage root rot, which will lead to rotten hearts.

    Cabbage is an indispensable vegetable in people's lives, especially in the winter in the north, people store a lot of cabbage for the winter, so cabbage shedding disease is a disease that farmers often encounter when planting cabbage, which seriously affects the yield and quality of cabbage.

    The disease can be prevented by spraying or field management.

    1) Choose disease-resistant varieties.

    2) Do not sow too early, try to avoid the high temperature and dry season.

    3) Strengthen field management. To prevent soil drought at the seedling stage, the ground temperature should be watered and cooled frequently in the case of high ground temperature in the dry year of the seedling stage to ensure the normal development of the root system.

    Pharmacy method. 1) The seedling stage should not be flooded with water, and it should be sprayed once with "Egenokepuc" in time after the seedlings.

    2) Irrigate the roots once with 50% carbendazim 1000g 30% oxazim aqueous 100ml Japanese granules magnesium 3000g when placing **, and the amount of medicine used for each plant is about 200ml.

    3) During the vertical tube period, the roots were irrigated once with 50% carbendazim 1000g and 75% chlorothalonil 1000g potassium dihydrogen phosphate 2kg per mu, and the amount of water used per plant was about 150ml.

    4) Less nitrogen fertilizer and more phosphorus, potassium and magnesium fertilizer.

    5) When it can be combined with insect control and disease prevention, add 30% oxamine water (10ml per bucket of water).

    6) When cultivating the field and preparing the land, "humic acid" can be added in real time and applied 80kg-100kg per mu.

    The base of the petiole and the rhizome completely decay and turn into a grayish-yellow sticky substance that emits a foul smell and falls down when the leaf bulbs are touched, which is called "rotten bumps". The inner and outer leaves are good, and only the middle leaves rot from the edge to the inside, commonly known as "skin rot". Prevention and control methods: Chemical control before the onset of the disease or at the beginning of the disease, should be started spraying to prevent transmission, spraying every 7 days or so.

    72% agricultural streptomycin 1000 times and neophytomycin 4000 times are commonly used. During the spraying, the petiole and stem base are mainly sprayed, so that the liquid can fully contact the short stem of Chinese cabbage, and the central diseased plant and its surroundings are specially sprayed to prevent spread.

    Do not store cabbage immediately after it has been cut. It is generally recommended to dry in the field for a period of time, with the roots facing the sun, so that the vegetable tree can stand upright and the outer leaves can be hung without folding. This can reduce mechanical damage, improve cold resistance, reduce the volume of cabbage, and increase storage.

    However, the drying of vegetables should not be excessive, otherwise, the tissues wilt, disrupt the normal metabolic function, strengthen hydrolysis, will promote cracking, reduce the storage tolerance and disease resistance of Chinese cabbage. Many farmers are stumped by the problem of Chinese cabbage. There are several key points, and the comprehensive prevention and control is effective in arranging the sowing date according to climatic conditions, and it is suitable for late sowing.

    Carry out the cultivation of high ridges and high furrows, and do a good job in the management of seedlings.

    Generally, maggots are controlled with phoxanthaphos when applying basal fertilizer. Because it is against the top of the cellar, it will cause poor ventilation and cause the cabbage to be peeled. After the cabbage enters the cellar, it needs a lot of ventilation to remove the heat from the cellar and prevent the cabbage from falling off.

    At the same time, the peasant doctor should be diligent in pouring out hemorrhoids. At this time, you must not be lazy, and you must pour the pile several times, so that the temperature of the cabbage can be quickly lowered. Choose disease-resistant varieties.

    Sow seeds at the right time, generally not too early, and try to avoid the hot and dry season. Strengthen on-site management.

    In dry years at the seedling stage, if the ground temperature is too high, it is necessary to water and cool down frequently to ensure the normal development of the root system. Pharmaceutical methods are not suitable for flood irrigation at the seedling stage. When placing **, water the roots once with 50% carbendazim 1000g 300ml of 300ml of Japanese granules magnesium, and each plant consumes about 200ml of water.

    During the riser period, 1000 g of 50% carbendazim, 1000g of 75% chlorothalonil, and 2kg of potassium dihydrogen phosphate were used to irrigate the roots once per mu, and the water consumption of each plant was about 150ml. Less nitrogen fertilizer and more phosphorus, potassium and magnesium fertilizer. When insect control and disease control are combined, when adding 30% 10ml of oxazole water agent to plough the land, humic acid can be added in real time, and 80-100 kg per mu can be applied.

    Prepare more plant ash (plant ash is to kill all kinds of insects that eat leafy vegetables), after transplanting, give a handful of plant ash to the vegetable seedlings next to the vegetables, so that insects can prevent eating vegetables, and the easiest way is: you can also find some stone powder to sprinkle next to the vegetables and cabbage leaves Control method: soak the seeds with warm water for half an hour before sowing, take out the sowing or germination sowing after cooling, or soak the seeds with 50% dyssenamine 200 times for 15 minutes, wash and dry the seeds.

    Reasonable crop rotation, reasonable fertilization, avoid partial application of nitrogen fertilizer, and the onset of disease is spraying Bordeaux liquid.

    There are not many diseases of cabbage, generally there are blight, leaf spots, mainly in the seedling stage. As long as it is well managed, it generally has little impact. The main insect infestation is very serious, and the most experienced infestation is cabbage worm, aphid and borerworm.

    Throughout the growth period, butterflies flutter and lay eggs that float into green insects that harm the leaves. The main insect pests of cabbage are: diamondback moth, cabbage worm, whitefly, aphid, etc.

    In spring, damage generally occurs after late April, and control measures should be taken in summer and autumn from one week after the emergence of seedlings. Virus diseases, black rot, root swelling, soft rot and so on will also occur during the planting process.

    Cabbage blight: also known as black root disease. It mainly infects the rhizomes of seedlings, and the pathogenic part turns black and shrinks, and the wet part lasts for a long time with white mold.

    After that, the leaves can be seen to wilt and even die. A small number of adult plants can still develop the disease. It is a soil-borne disease, and seeds, bacterial, organic fertilizers, etc. can also spread, and insect pests such as aphids and cabbage insects can also occur in the management of vegetable seedlings.

    These pests often hide on the back of the leaves to breed and multiply, if not controlled early, it will be difficult to control when the pest increases, even if a lot of pesticides are sprayed.

    Prevention and control methods: when the larvae are harmed, start spraying pesticides, commonly used pesticides are chrysanthemum emulsifiable concentrate, chrysanthemum emulsifiable concentrate, the control effect is better, but pay attention to the alternate use of pesticides, so as not to cause resistance. It is necessary to take preventive measures, rotate crops reasonably, reduce soil germs, and carry out pesticide seed dressing on planting before sowing and planting to eliminate the germs carried by seeds.

    When one or two plants become diseased, they can be directly uprooted and taken out of the field, and the disease hole can be disinfected.
