Field management methods of mustard

Mustard is an annual herb of Cruciferae, its plant is relatively tall, the tallest can grow to about 1.5 meters. The whole plant of mustard has utilization value, the leaves are edible, the seeds can be used as medicine, and it is also the main raw material of mustard, and it is also an oil crop. Mustard has a certain cultivation area in all parts of our country, so how to manage mustard cultivation? The following editor brings you the field management method of mustard. Let's have a look!

1. Seedling stage management

The growth rate of mustard after sowing and emergence is very fast, so we should do a good job of interplanting after emergence, and start when the seedlings grow a true leaf. Expand the planting spacing to avoid growing too dense in the middle and later stages, resulting in tall seedlings. Then, when the seedlings grow 2-3 true leaves, the seedlings are fixed to retain the characteristics of the seedlings to ensure that there is enough space for the seedlings to grow and increase the yield. Mustard plants are tall and should not be planted too densely to prevent overgrowth.

2. Ploughing and weeding

In the growth of mustard, it is necessary to ensure that the soil is soft enough and permeable, so we should regularly plough and weed, improve soil oxygen content, water and fertilizer conservation, and promote the growth of mustard. Although the growth ability of mustard is relatively strong, it can not relax the weeding work, because the nutrient grabbing ability of weeds is very strong, which will seriously hinder the growth of mustard. In the whole growth period of mustard, at least two intermediate ploughing and weeding should be carried out to create a good environment for mustard growth.

3. topdressing at the right time

Fertilizer is the key to ensure the high yield of mustard, especially for the soil with insufficient base fertilizer or barren soil. Before the ridge is closed, the soil needs to be fertilized every time it is cultivated. Attention should be paid to the concentration and amount of fertilizer, usually 20 kg / mu, mainly urea and potassium chloride. Fertilization methods should be paid attention to, should be evenly sprinkled in the furrow, do not let mustard roots come into contact with fertilizer, prevent fertilizer heat from burning roots, affecting the growth of mustard.

4. Water management

Mustard does not need much water at the seedling stage. Rain Water can meet the water demand at the seedling stage, but if it does not rain for a long time, it still needs proper watering. Especially in the long-term dry environment, it is necessary to irrigate at least once a day. The lack of water in the seedling stage not only affects growth, but also increases the incidence of various diseases and insect pests. Mustard should be based on the principle of no drought and no watering in the middle stage, avoid the excessive growth of mustard, keep the soil moist in the later stage and promote the expansion of the rhizome.

5. Pest control

The growth ability and disease resistance of mustard are relatively strong, so the incidence of disease in growth is not high. However, it will be threatened by some insect pests, such as aphids, cabbage insects, etc., and these pests will cause some diseases. Therefore, the prevention and control of diseases and insect pests is still a good management work that we need to do in planting, reduce the source of diseases in the field, strengthen field management, and deal with pests in time after finding pests. Most pests can be sprayed with insecticides commonly used in the market. However, we mainly focus on prevention, as long as we do a good job in every management of the planting process, we can effectively prevent it.

The above is a brief introduction to the field management methods of mustard. In order to promote the growth of mustard, we can spray appropriate growth regulators after the seedlings are fixed. Enhance the photosynthesis of mustard leaves, improve nutrition accumulation, promote the growth of mustard, but pay attention to the dosage, not excessive, otherwise mustard will grow too much, but the loss will outweigh the gain and lead to a decline in yield.
