The latest course of field management techniques and methods of amaranth

Amaranth, also known as wild goose red, red amaranth, is a kind of characteristic vegetables, amaranth soup is red, and taste very delicious. Moreover, amaranth also has the effects of invigorating qi and clearing heat, clearing kidney and detoxification. There is a wide range of planting area in our country, but it is necessary to do a good job of management when planting. The following small series brings you the field management technology of amaranth planting. Let's have a look together!

1, adjust the temperature

Amaranth to the temperature requirements are relatively large, cold resistance is not high, so in winter and early spring when the film should be uncovered in time, and then watering in the greenhouse, and then build an arch shed, improve the greenhouse heat preservation capacity. Prevent amaranth from freezing injury and improve overwintering survival rate. And when the temperature drops, try to cover a layer of grass in the evening to keep warm. Then pay attention to the cooling work in summer, especially for seedlings, to set up shading facilities in time, and to open them properly at night.

2. Reasonable watering

Amaranth also has a certain demand for water. In winter and spring, it is necessary to ensure that the soil is moist and watered regularly. However, attention should be paid to the way of watering. It is not allowed to flood irrigation to prevent accumulated water from causing the roots of Amaranth to rot and causing diseases and insect pests. And when watering, try to choose a higher temperature to prevent the water temperature from being too low to cause amaranth to freeze. Then, urea water should be properly applied after the seedlings are fully seedlings, and once a week in the middle and late stages to promote the growth of amaranth. Increase watering frequency in summer, when not at noon when the sun is strongest, should be watered in the morning and evening.

3. Appropriate topdressing

Although the growth period of amaranth is not long, but the demand for nutrition is relatively large, so in the planting process to carry out multiple water and fertilizer work. Generally, when amaranth seedlings grow to 3 true leaves, they can start topdressing, and then topdressing again after about 2 weeks. And because amaranth is a multi-year, a year can be harvested many times a vegetable, so each harvest once to topdressing. Improve nutrient ratio and promote the growth of subsequent amaranth. Pay attention to the fertilizer nutrition ratio when fertilizing, mainly nitrogen fertilizer, but also add appropriate amount of phosphorus and potassium fertilizer, not excessive partial application, to prevent excessive growth and lack of symptoms.

4. Pest control

The control of diseases and insect pests of amaranth should be paid attention to in the whole growth period. Diseases and insect pests will harm the leaves, rhizomes and other parts of amaranth. We should observe the field regularly and disinfect the soil regularly to reduce pathogens. After finding the disease, we should cut off or remove the diseased part in time, and then use the corresponding prevention and control measures to prevent and control it. Strengthen water and fertilizer management, control drug dosage, pay attention to various abnormal situations. Early detection and early treatment of diseases and insect pests should be achieved to avoid greater losses.

The above is a simple introduction to amaranth field management technology, amaranth planting although relatively simple, but also under the premise of careful management. Therefore, only by doing these field management work well can we ensure the normal growth of amaranth, improve yield and ensure their own economic benefits.
