Scientific Control of Cabbage Root Rot

Cabbage-natural stomach vegetables cabbage flat taste sweet, non-toxic, into the stomach, kidney meridians. Cabbage is one of the best vegetables recommended by the World Health Organization, and it is also known as the natural "stomach dish". The vitamin K1 and vitamin U contained in it can not only resist gastric ulcer, protect and repair gastric mucosal tissue, but also keep gastric cells active and exuberant and reduce the probability of pathological changes. It is beneficial to hormone secretion and breast development. All kinds of kale are good sources of potassium. Cabbage is also rich in vitamin A, calcium and phosphorus. Cabbage is eaten raw or taken with fresh juice (200 to 300 C.C.) on an empty stomach, two to three times a day for the best results. However, cabbage contains more crude fiber than Chinese cabbage, so it is hard and should not be used by people with poor digestive function.

Cabbage is warm and moist, with plenty of light. More cold-resistant, but also have the ability to adapt to high temperature. The suitable temperature for growth is 15-20 ℃. If the fleshy stem is enlarged at a high temperature of more than 30 ℃, the fleshy stem is prone to fibrosis. The selection of soil is not very strict, but it is suitable for planting in humus-rich clay loam or sandy loam. Cabbage seedlings must undergo vernalization at 0-10 ℃, then bolting, flowering and fruiting under long sunshine and suitable temperature.

How to prevent and cure cabbage root rot?

The main symptoms of cabbage root rot:

The disease occurs in the seedling stage or shortly after planting, the basal epidermis of the stem becomes brown and rotten, then the root system decays, and the diseased plant is easily pulled out.

The conditions for the occurrence of cabbage root rot:

Overwintering with mycelium in seeds and soil. The disease occurs on cabbage plants covered with plastic film or cultivated in small arch greenhouse or plastic greenhouse in early spring, which belongs to low temperature and high humidity disease, and the pathogen spreads with irrigation water.

Scientific control methods of root rot of cabbage

1. Seed treatment: select good varieties, soak the seeds with 800 times wilting Antai solution for 4 hours, rinse the seeds with clean water twice, accelerate germination and sow seeds after leaching, or disinfect with 1% salt water.

2. Soil treatment of seedling bed: the bed soil was disinfected with 1000-fold solution of carbendazim, or mixed with 1000-fold solution of withered Antai, and matrine powder 11000-fold could be used to control underground pests. The seedling bed should be flat to facilitate watering in the future, and the thickness is generally about 10 cm. Using organic bioactive fertilizer as seedling fertilizer can significantly improve the resistance of cabbage to root rot.

3. Sowing and raising seedlings: spread the germinated seeds on the seedling bed and cover the soil, generally covering about 1 cm of soil, and it is appropriate to cover the soil with sandy loam. Cover the soil with plastic shed cloth to increase the temperature to facilitate seedling emergence. Pay attention to do not flood irrigation, in order to prevent high humidity and low temperature, causing a variety of seedling bed diseases.

4. Seedbed management: after the seedlings are unearthed, sprinkle water at the right time to prevent water shortage, but do not flood irrigation. When 30% of the seedlings emerge, spray the seedling bed and seedlings with wilt Antai 500 times liquid for 2-3 times to prevent blight, sudden collapse and root rot, with an interval of 7-10 days. Spraying Weisheng D1300 solution for 1-2 times after seedling emergence, with an interval of 10-15 days, can promote the robust growth of seedlings and prevent the invasion of diseases. After the seedling is big, pour the seedling in time, take the plant as the unit, the interval is 2 inches. After pouring the seedlings, they should be watered and should not be flooded. Let out and air the seedlings in time before transplanting to make the seedlings aging. The day before transplanting, the flood water should be watered once and thoroughly.

5. Planting management: when planting, spray the seedling bed and seedlings with 300 times solution of wilting Antai or 500 times solution of 50% Gen Yuling and other fungicides to prevent seedlings from entering the greenhouse with bacteria. When planting, it can be planted between leek and cabbage, which can reduce the root rot of cabbage, this is because leek can produce a strong and special smell, which can be dewormed and sterilized.
