Cultivation Methods and Technical Key Points for Red Chinese Kale
Choose a plot of sandy soil with sufficient fertility, deep plow it and apply enough base fertilizer. Then evenly sow relatively strong-resistant seeds onto the seedbed, then cover with a layer of dry grass or animal manure, and water lightly to let them germinate. When the seedlings grow four to five true leaves, transplant them into the field at a row and plant spacing of 30*40cm, finally cover with soil, and complete basic management work such as watering, fertilizing, and pest and disease control.
Detailed Explanation of Red Chinese Kale Cultivation Methods:
1. Land Selection and Preparation
The most suitable land for planting red Chinese kale 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 is generally done as early as possible, then let the land be exposed to the sun for about ten days. Before sowing, loosen the land slightly, then spread sufficient fertilizer. Generally, about 500 kg of farmyard manure and 200 kg of compound fertilizer are needed per mu.
2. Sowing and Seedling Raising
For seed selection, 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 placed on top, which can raise the soil temperature and let the seeds germinate 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 Chinese kale seedlings grow four to five leaves, they can be transplanted. We pull the seedlings from the seedbed, then plant them in the prepared land at a spacing of 30 to 40 cm per plant. Maintaining this spacing allows the red Chinese kale to grow larger, and the more red Chinese kale it produces when mature.
4. Field Management
After transplanting, remember to water them. The newly transplanted seedlings are relatively fragile and need sufficient nutrients and moisture to promote new root growth and new leaf development, 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 Chinese kale, 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 Chinese kale can be continuously harvested and grown, so the soil fertility must be maintained. Generally, three to four additional fertilizer applications are needed. Basically, after each harvest, a little urea and potassium chloride can be applied as additional fertilizer.
5. Pest and Disease Control
During the growth of the rosette leaves of red Chinese kale, the most common disease is downy mildew, a disease that many vegetables often suffer from, so the treatment method is the same as for vegetables. Spray with a pesticide targeting downy mildew two or three times. Finally, red Chinese kale often has 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 Chinese kale is harvested in batches. The red Chinese kale it produces each time grows at different speeds, so when the kale shoots grow to about 30 to 40 cm, they can be harvested. After harvesting, an appropriate amount of fertilizer can be added to promote the growth of the kale shoots. Basically, it can be harvested once or twice a week. Be sure to harvest promptly, otherwise if it grows too long it will become hard, and then it will be useless.
The above is the relevant introduction to the cultivation methods of red Chinese kale. We hope it is helpful to everyone.
