Key field management techniques for amaranth: teaching you to grow high-yield amaranth
Amaranth, also known as Joseph's coat and red amaranth, is a rather distinctive vegetable. The soup made from amaranth is red, and its flavor is very delicious. Amaranth also has effects such as tonifying qi and clearing heat, and cleansing the kidneys and detoxifying. It has a wide planting area in our country, but management work needs to be done well when planting. Below, the editor brings you the field management techniques for amaranth cultivation. Let's take a look!
1. Adjusting the temperature
Amaranth has relatively high temperature requirements and is not very cold-tolerant. Therefore, in winter and early spring, the plastic film should be uncovered in time, then water should be applied in the greenhouse, and an arched shed should be built to improve the greenhouse's heat preservation capacity. This prevents amaranth from suffering cold damage and improves the overwintering survival rate. Also, when the temperature drops, a layer of straw should be spread again in the evening as much as possible for heat preservation. Then in summer, attention should be paid to cooling work. Especially for seedlings, shade facilities should be set up in time, and they should be properly uncovered at night.
2. Reasonable watering
Amaranth also has a certain demand for water. In winter and spring, the soil should be kept moist and watered regularly, but attention should be paid to the watering method. Do not use flood irrigation, to prevent water accumulation from causing amaranth root rot and triggering diseases and pests. Also, when watering, choose a time when the temperature is relatively high as much as possible, to prevent the water temperature from being too low and causing cold damage to amaranth. Then, after the seedlings emerge fully, appropriately apply urea water, about once a week in the middle and late stages, to promote the growth of amaranth. In summer, the watering frequency should be increased, but it should not be done at noon when the sunlight is strongest; water in the morning and evening instead.
3. Appropriate topdressing
Although the growth period of amaranth is not long, its demand for nutrients is relatively high. Therefore, multiple rounds of water and fertilizer application should be carried out during the planting process. Generally, topdressing can begin when amaranth seedlings grow to 3 true leaves, and then topdressing should be done again after about 2 weeks. Also, because amaranth is a vegetable that grows for more than a year and can be harvested multiple times a year, it should be topdressed once after each harvest. Increase the nutrient ratio to promote the growth of subsequent amaranth. When fertilizing, pay attention to the nutrient ratio of the fertilizer, mainly nitrogen fertilizer, but also add an appropriate amount of phosphorus and potassium fertilizer. Do not overapply or apply a single nutrient excessively, to prevent excessive vegetative growth and deficiency symptoms.
4. Disease and pest control
Disease and pest control for amaranth must be emphasized throughout the entire growth period. Diseases and pests harm the leaves, roots and stems, and other parts of amaranth. We should observe the field regularly and disinfect the soil periodically to reduce pathogens. After discovering any occurrence of disease, promptly cut off or remove the affected parts, and then use corresponding control measures for prevention and treatment. Strengthen water and fertilizer management, control the amount of pesticide used, and pay attention to various abnormal situations. Achieve early discovery and early treatment of diseases and pests to avoid greater losses.
The above is a brief introduction to amaranth field management techniques. Although amaranth cultivation is relatively simple, it is still premised on careful management. Therefore, when planting, only by doing these field management tasks well can you ensure the normal growth of amaranth, increase yield, and guarantee your own economic benefits from planting.
