Field management techniques of amaranth

Amaranth, also known as Yanlai Hong, red amaranth and so on, is a kind of characteristic vegetable. The soup made of amaranth is red and delicious. And amaranth also has the effects of invigorating qi and clearing heat, clearing the kidney and detoxification. There is a wide range of planting areas in our country, but we need to do a good job in management when planting. The following editor brings you the field management technology of amaranth planting. Let's have a look!

1. Adjust the temperature

The temperature requirement of amaranth is relatively large, and the cold resistance is not high, so the plastic film should be opened in time in winter and early spring, then watered in the greenhouse, and then build an arch shed to improve the heat preservation capacity of the greenhouse. Prevent amaranth from freezing injury and improve the survival rate of overwintering. And when the temperature drops, you should try to cover another layer of forage in the evening to keep warm. Then in the summer to pay attention to cooling work, especially for seedlings, to build shading facilities in time, and in the evening to properly uncover.

2. Rational watering

Amaranth also has a certain demand for water, in winter and spring to ensure that the soil is moist, regular watering, but to pay attention to the way of watering, not flooding, to prevent stagnant water leading to amaranth root rot, causing diseases and insect pests. And when watering, we should try to choose when the temperature is high to prevent the low water temperature from causing freezing damage to amaranth. Then urea water was properly applied after seedling completion, once a week or so in the middle and later stage to promote the growth of amaranth. It is necessary to increase the frequency of watering in summer, when the sun is strongest at noon, but in the morning and evening.

3. Proper topdressing

Although the growth period of amaranth is not long, but the demand for nutrition is relatively large, so many times of water and fertilizer work should be carried out in the planting process. Generally speaking, when the amaranth seedlings grow to 3 true leaves, you can start topdressing, and then topdressing again after about 2 weeks. And because amaranth is a vegetable that is more than one year old and can be harvested many times a year, it is necessary to top fertilizer every time it is harvested. Increase the proportion of nutrition and promote the growth of follow-up amaranth. When fertilizing, we should pay attention to the proportion of fertilizer nutrition, mainly nitrogen fertilizer, but also add an appropriate amount of phosphorus and potassium fertilizer, not over-application, to prevent excessive growth and symptoms of element deficiency.

4. Pest control

The prevention and control of diseases and insect pests of amaranth should be paid attention to during the whole growth period, and the diseases and insect pests will harm the leaves, roots and other parts of amaranth. We should observe the field regularly and disinfect the soil regularly to reduce pathogens. When the disease is found, the disease site should be cut off or removed in time, and then the corresponding prevention and treatment measures should be used for prevention and treatment. Strengthen the management of water and fertilizer, control the amount of medicine, and pay attention to all kinds of abnormal situations. To achieve early detection and treatment of diseases and insect pests to avoid greater losses.

The above is a brief introduction to the field management technology of amaranth. Although the cultivation of amaranth is relatively simple, it is also under the premise of careful management. Therefore, when planting, only by doing a good job in the field management, can we ensure the normal growth of amaranth, increase the yield and ensure the economic benefits of planting.
