The Latest Cultivation Techniques and Methods Tutorial for Red Cabbage Sprouts

Red cabbage sprouts are a new variety of choy sum, mainly grown for the edible stems that the vegetable produces. Generally, red cabbage sprouts are sown from July to September each year, with sowing carried out scientifically according to the different environments of different regions, so sometimes the red cabbage sprouts you buy are very sweet and sometimes have a bitter taste, which is caused by the different sowing times. Today, let us follow Qinnongwang to learn how red cabbage sprouts are grown.

1. Land selection and preparation

The most suitable land for planting red cabbage sprouts is relatively fertile sandy soil, but at the same time it must have strong water retention and drainage capacity. Generally, a section with relatively abundant water sources is chosen. For land preparation, it should generally be done as early as possible, then let the land be exposed to the sun for about ten days. Before sowing, loosen the land slightly again, then spread sufficient fertilizer. Generally, about 500 kg of farmyard manure and 200 kg of compound fertilizer are needed per mu.

2. Sowing and raising seedlings

When selecting seeds, generally choose varieties with relatively strong resistance. When sowing, first water the seedbed once, then scatter the seeds densely onto the seedbed, then cover with a thin layer of soil. At the same time, a layer of dry grass or animal manure can also be covered on top, which can raise the soil temperature and let the seeds sprout faster. After the seeds sprout tender shoots, water once to give them sufficient moisture so they can develop faster.

3. Planting method

When the red cabbage sprout seedlings grow four or five leaves, they can be transplanted. We pull the seedlings out from the seedbed, then plant them in the prepared land at a spacing of 30 to 40 cm per plant. Maintaining this distance allows the red cabbage sprouts to grow larger, and when they do, more red cabbage sprouts will be produced.

4. Field management

After transplanting, remember to water them. Newly transplanted seedlings are relatively fragile and need sufficient nutrients and moisture to promote the growth of new roots and new leaves, so about ten days after transplanting, fertilize them once. Generally, urea is used, because urea mainly promotes the growth of branches and leaves, and the effect is very obvious. Generally, leafy vegetables are given urea. During the growth period of red cabbage sprouts, the soil must be kept moist. If there is no rain, water regularly, generally once every five to seven days, because during the growth period red cabbage sprouts can be continuously harvested and continue growing, so soil fertility must be maintained. Generally, three to four topdressings are needed. Basically, after each harvest, a little urea and potassium chloride can be applied as a topdressing.

5. Pest and disease control

During the growth of the rosette leaves of red cabbage sprouts, the most common disease is downy mildew, a disease that occurs frequently in many vegetables, so the treatment method and materials are the same as for vegetables. Spray two or three times with a pesticide targeting downy mildew. Finally, red cabbage sprouts often have some pests and diseases, such as diamondback moth and aphids. These can be treated with common pesticides. Once symptoms are found, they must be treated promptly.

6. Harvesting method

Red cabbage sprouts are harvested in batches. The red cabbage sprouts produced each time grow at different speeds, so when the sprouts grow to about 30 to 40 cm, they can be harvested. After harvesting, an appropriate amount of fertilizer can be added to promote sprout growth. Basically, they can be harvested once or twice a week. Be sure to harvest promptly, otherwise if they grow too long they will become hard, and then they will be useless.
