How to make Chinese cabbage grow core quickly (how to make small cabbage grow core quickly)

Cabbage is one of the indispensable vegetables in our lives. It grows fast and has a short growth cycle, but improper management will cause the cabbage to not grow a heart (wrap a heart), affecting yield and quality.

Reasons why Chinese cabbage does not grow heart:

1. Sowing too early

Unable to adapt to climatic conditions leads to lack of patience.

2. Lack of water

During the growth process of cabbage, the water requirement is very large. Failure to water it in time will cause the cabbage to not grow heart.

3. Improper fertilization

During the growth process of cabbage, excessive application of nitrogen fertilizer may cause the leaves to grow wildly, while not paying enough attention to the application of phosphorus and potassium fertilizers, resulting in excessive nitrogen fertilizer and insufficient phosphorus and potassium fertilizers, causing the cabbage to not grow core.

4. Improper drainage

If there is too much rain, the fields will be waterlogged and humid, which will affect the growth of the cabbage roots and cause the cabbage to not grow heart.

5. Pests and diseases

During the growth process, Chinese cabbage is susceptible to many diseases and pests, such as soft rot, dry heart disease, powdery mildew, cabbage worm, diamondback moth, aphids, etc. The occurrence of diseases will affect the growth of cabbage and cause the cabbage to not grow heart.

We all know that cabbage is a leafy vegetable and one of the most commonly eaten vegetables. The quality of the cabbage is greatly affected by whether the cabbage is firm or loose. What method can be used to make the cabbage wrap faster?

1. Scientific topdressing in stages

Chinese cabbage is a leafy vegetable that requires more nitrogen, but the more nitrogen the better. After the cabbage is planted, until the cabbage heads, it mainly grows for nutrition.

Using more nitrogen fertilizer can promote the growth of cabbage plants to be larger and greener. On the basis of sufficient base fertilizer and farmyard manure, apply more nitrogen-based fertilizer.

In this way, the cabbage plants grow rapidly, and then adding phosphorus and potassium fertilizers will make the cabbage grow stronger and more vigorous.

When the cabbage is in the head stage, high-nitrogen and high-potassium compound fertilizer is applied, about 25 to 30 kilograms per mu of land. The cabbage will not be depleted of fertilizer, so it will naturally grow faster when it is in the head stage.
2. Reasonable watering

Cabbage has a high water content, more than 95% water, which makes it taste crispy and tender. The fat and calorie content is very low.

Proper watering of cabbage is a good way to promote its growth and head formation. Cabbage likes water but cannot tolerate waterlogging. In the middle and late stages of cabbage heading, the soil moisture content is most suitable at around 80%.

However, the soil moisture content should not be too high from the time the cabbage is planted to the rosette stage. The soil moisture content can be maintained at 60%~65%.

When cabbage enters the heading stage, you cannot use the method of flooding with water, as the surface water will not seep into the ground for a long time. You should water it on the same day, and after a few hours, there will be no visible water on the ground.

Otherwise, too much moisture in the soil will hinder root respiration and affect the normal growth of cabbage.

Then it will affect the speed of cabbage wrapping. When watering, phosphorus and potassium fertilizers, chitin, amino acid water-soluble fertilizers, biogas slurry, etc. can be flushed out with water.

3. Spray foliar fertilizer

If you want cabbage to form a heart quickly, in addition to underground fertilization and watering, spraying foliar fertilizer can promote the rapid formation of cabbage. Generally, spray once every 7 to 10 days, with brassinolide + chelated calcium + a variety of medium and trace element fertilizers , etc.

Then, spraying alternately with Tianda 2116 + Aiduoshou + potassium dihydrogen phosphate + chelated calcium, etc. can promote the cabbage to grow stronger and help it to wrap the heart quickly .

4. Prevent and control pests and diseases

Pests and diseases can harm the normal growth of cabbage. During the growth period of cabbage, you can choose protective fungicides, such as thiophanate-methyl, mancozeb, sinocycline, and cefotaxime acetate.

Pesticides can be selected, such as clothianidin suspension, chlorantraniliprole suspension, Bacillus thuringiensis insecticide, lufenuron insecticide, etc. Root rot of Chinese cabbage will affect its normal growth.

Generally, prevention should be the priority. Rotten cabbage should be taken out of the field in time, and quicklime should be sprinkled on the area where the rotten cabbage was to disinfect it in order to prevent the spread of the disease.

5. Another reason that affects the cabbage heart is the wrong variety selection

Cabbage prefers cool weather in autumn, but is heat-resistant in summer. It is very necessary to find the right season and choose the appropriate cabbage variety for planting.

If the cabbage varieties that are more tolerant of cool temperatures in autumn are planted in summer, they will not grow fast and will not form the core well.

In addition, use straw rope to tie the outer leaves of the cabbage to force it to wrap around the heart. This should be done two weeks before harvesting the cabbage.
