Detailed Explanation of Turnip Cultivation Techniques and Key Points of Field Management
Turnip is a biennial herbaceous plant belonging to the Brassicaceae family. Its plant is relatively taller than some other herbaceous plants, reaching up to 1 m at its tallest. It is mainly grown for its tubers, which are widely used in China to make pickles and sauerkraut, and also as feed for many poultry. Turnip has high nutritional value, can moisturize the skin and resist aging, and strengthens the body. So how should turnip be cultivated? Today, the editor brings you the cultivation techniques for turnip. Let's take a look!
1. Land Preparation and Fertilization
The growing environment of turnip is similar to that of radish. It is suitable for planting in soil with abundant fertility, soft texture, and rich humus, which helps increase the growth rate of turnip. After selecting the land, land preparation must be done well. Land preparation is to improve soil fertility, enhance permeability, and disinfect and sterilize. During land preparation, fertilize at the same time. Organic fertilizer and farmyard manure can be used as base fertilizer to ensure that turnip seeds take root and germinate. Land preparation and fertilization is the first step in turnip cultivation and also the most important step. The amount of base fertilizer should be reasonably controlled according to the soil area, and it should not be too much or too little.
2. Thinning and Final Thinning
After sowing and emergence, regularly observe the growth of the seedlings. If abnormal seedlings result in weak or dead seedlings, pull them out and replant with healthy turnip seedlings. Then thin the seedlings at the right time, because turnip plants are relatively tall. If not thinned, they are likely to be planted too densely after growing up and affect each other's growth. Generally, thinning should be carried out twice: first after the cotyledons of the seedlings unfold and true leaves grow, and then again when about 3 true leaves have grown. Also, when 2-3 true leaves have grown, complete the final thinning.
3. Fertilizer and Water Management
Turnip has a relatively large demand for fertilizer and water. After sowing turnip, the soil must be kept moist. However, because the temperature in spring has not yet risen, reduce the frequency of watering and strengthen intertillage management. In the high-temperature and dry season of summer, the watering interval must not exceed one week at most. During the peak leaf growth period, control moisture well and water in a timely manner according to soil moisture content, plant growth conditions, and weather changes. In addition to applying sufficient base fertilizer before planting, turnip must also receive at least one topdressing during the growing period to ensure that turnip has enough nutrients for its growth.
4. Pest and Disease Control
When turnip is improperly managed, various pests and diseases often occur, and the threat of pests and diseases is far greater than other threats during growth. Therefore, we must strengthen field management of turnip to reduce the incidence of various pests and diseases. While strengthening management, we should also understand the common pests and diseases of turnip. Common pests and diseases of turnip include viral disease, downy mildew, aphids, and cabbage caterpillars, etc. Each pest and disease has different chemical control methods. For example, the corresponding control agent for viral disease includes plant virus disease control emulsifiable concentrate, and downy mildew can be treated with metalaxyl wettable powder and other agents.
In pest and disease control work, everyone should not only do prevention work well, but also have management measures to deal with sudden diseases. Prepare commonly used disease treatment agents to prevent being at a loss when pests and diseases occur and causing greater losses. Therefore, everyone must pay more attention in this regard.
