The latest course of cultivation techniques and methods of turnip

Turnip is a biennial herb belonging to Cruciferae, its plant is relatively tall compared to some other herbaceous plants, the highest can reach 1 meter. Mainly feed on tubers, it is widely used in making kimchi and sauerkraut in China, as well as feed for many poultry. Turnip has high nutritional value, can moisturize the skin and resist aging, and strengthen the body. So how to grow turnips? Today, the editor brings you the cultivation techniques of turnip, let's have a look!

1. Soil preparation and fertilization

The growth environment of turnip is similar to that of radish, and it is suitable to be planted on the soil with rich energy, soft soil and rich humus, which is helpful to improve the growth rate of turnip. After selecting a good site, it is necessary to do a good job in soil preparation, which is to improve soil fertility, enhance permeability, disinfect and sterilize. When soil preparation is combined with fertilization, organic fertilizer and farm manure can be used to ensure that turnip seeds take root and sprout. Soil preparation and fertilization is the first and most important step in turnip cultivation. The amount of base fertilizer should be reasonably controlled according to the soil area, not too much or too little.

2. The seedlings are fixed

When sowing and emergence, the growth of seedlings should be observed regularly. If abnormal seedlings lead to weak or dead seedlings, they should be pulled out and the robust turnip seedlings should be mended. Then suitable time seedlings, because the turnip plant is relatively tall, different seedling life, after growing up, it is easy to plant too dense, affect the growth of each other. Generally, the seedling work should be carried out twice, first after the cotyledons of the seedlings are expanded to grow true leaves, and then again when about 3 true leaves are grown. And wait until the growth of 2-3 true leaves to do a good job of seedling determination.

3. Fertilizer and water management

Turnip has a large demand for fertilizer and water, so it is necessary to ensure that the soil is moist after turnip sowing, but because the temperature does not rise in spring, it is necessary to reduce the frequency of watering and strengthen the management of intertillage. In the hot and dry summer season, the watering interval should not exceed one week at most. During the peak period of leaf growth, water should be controlled and watered timely according to soil water content, plant growth and weather changes. In addition to pouring sufficient fertilizer before planting, the turnip should not be less than one topdressing during the growing period to ensure that the turnip has enough nutrition for its growth.

4. Pest control

Under the reason of improper management, turnips often have a variety of diseases and insect pests, and the threat of diseases and insect pests is far greater than other threats in growth. Therefore, we must strengthen the field management of turnips to reduce the incidence of various diseases and insect pests. While strengthening the management, we should also do a good job in understanding the common diseases and insect pests of turnip, such as virus disease, downy mildew, aphids and cabbage insects. There are different drug control methods for each kind of diseases and insect pests, for example, the corresponding control agents for viral diseases are Zhanshanling EC, and downy mildew can be treated with metalaxyl wettable powder.

In the prevention and control of diseases and insect pests, we should not only do a good job in prevention, but also have management measures to deal with sudden diseases. Prepare drugs for the treatment of common diseases to prevent the occurrence of diseases and insect pests at a loss, resulting in greater losses. Therefore, we must pay more attention to this aspect.
