Is the blood red?

Red amaranth has purplish red tender leaves, contains more iron, calcium and other minerals, and contains more carotene and vitamin C. it is one of the most popular green leafy vegetables in summer. So, is blood skin red amaranth?

Is blood skin red amaranth?

Blood skin is not red amaranth. Red amaranth is an annual herb with tender stems and leaves for consumption. Blood skin is a perennial herb of Panax notoginseng in Compositae, which can be used for cooking and medicine.

What are the cultivation techniques of red amaranth?

1. Soil

Amaranth has strong adaptability to soil, clay or sandy soil with flat terrain and convenient drainage and irrigation can be selected, and alkaline soil is the most suitable. Planting under the condition of sufficient water and fertile soil is more beneficial to improve yield and quality.

2. Soil preparation and fertilization

Apply base fertilizer before soil preparation, apply rotten organic fertilizer 2000kg per mu, turn deeply after fertilization, make a border after turning, and make a ridge with soil, the height of the border is 10cm, the width of the border is 1m, and the length of the border is determined according to the plot. After making the bed, the bottom fertilizer should be applied once, and the compound fertilizer with nitrogen, phosphorus and potassium content of 15:15:15, 50kg per mu. Spread evenly to avoid excessive local fertilization and seed burning. Scrape the soil with a rake and mix the soil with fertilizer evenly. Because the seeds of amaranth are small, the soil is fine when raking, which is conducive to seedling emergence.

3. Sowing seeds

As the seeds of amaranth are small and not easy to spread evenly, mix fine sand and seeds at 1:5 before sowing and sow them directly on the ground. The amount of pure amaranth seeds per mu is about 0.6kg, rake the border surface with a rake after sowing, so that the amaranth seeds are covered with a layer of soil, and then step on the border surface to prevent the seeds from being washed away during watering, resulting in uneven germination.

4. Watering

When watering, spray water should be sprayed to prevent the border surface from rushing out of the pit, where there are no seeds, to prevent excessive water from washing away the seeds. Sowing amaranth in spring, due to less precipitation, dry air and large surface evaporation after watering, it is easy to make the soil surface hard and dry. Amaranth seeds can not break the topsoil layer and do not emerge after germination. After all the water seeps into the soil, the plastic film is covered on the border surface and compacted with soil around the plastic film, which can increase the ground temperature and promote seed germination as soon as possible.

5. Field management

Weeding: amaranth seedlings are small, more than ten days, weeds are much higher than seedlings, must be pulled out in time, otherwise compete with amaranth for nutrients, affecting the lighting of amaranth.

Topdressing: after sowing for about 20 days, topdressing was carried out for the first time when the seedlings grew more than 2 leaves. Choose sunny day, apply ammonium sulfate 15kg per mu, and water it in time after fertilization. The second topdressing was carried out 12-15 days after the first topdressing. Apply fertilizer for the third time after the first harvest, the usage is the same as above, in order to promote the growth of smaller amaranth after harvest, pay attention to timely watering after each fertilization and pull out weeds.

6. Pest control

The common diseases of amaranth are powdery mildew, anthrax, brown spot, virus disease and mole cricket.

Prevention and control methods:

1. Carry out flood-drought rotation and intensive farming. Apply fully mature organic fertilizer.

2. Poison bait: cooked with chaff and mixed with 90% trichlorfon, sprinkled on the border. In the sowing ditch, the tunnel where the mole cricket moves.

3. Manual hunting: in early spring, according to the empty mouth of the tunnel caused by mole cricket, look for worm nests to hunt and kill.

4. Medicament method: sprinkle the ground with 5% phoxim granule 1~1.5kg per mu, and then rake into the ground.

Blood skin and red amaranth both have purplish red tender leaves, but they are different vegetables, so we should pay attention to distinguish them when buying.
