How to Grow Blood-amaranth? Detailed Explanation of Planting Methods and Key Technical Points
Blood-amaranth is also called Guanyin vegetable or blood fern, and its main effect is to enrich the blood, making it an excellent blood-enriching health vegetable. At present, blood-amaranth is very popular on the market, but its output has not increased significantly. In China, blood-amaranth is mainly grown in Fujian, Sichuan, Guangxi, Hunan and other places, and the planting scale is not very large. So today let us learn about the planting methods of blood-amaranth.

1. Planting Environment
Blood-amaranth has strong resistance and the characteristics of being easy to survive, easy to manage, tolerant of poor soil, and strongly disease-resistant, making it a vegetable that can be planted all year round. However, in order to ensure the quality of blood-amaranth, the soil where it is planted is required to be pollution-free, the water quality pure, and the natural ecological environment relatively good. To increase the yield of blood-amaranth, the planting site should be rich in organic matter, and the soil should have strong fertilizer-retention and water-retention capacity. Finally, carry out land preparation and apply sufficient base fertilizer. The base fertilizer is mainly organic fertilizer, combined with compound fertilizer, urea and phosphate fertilizer for deep plowing, and after preparing the beds, planting can begin.
2. Planting Methods
Blood-amaranth has two cultivation methods, but at present the most commonly used one is propagation by cuttings, because blood-amaranth planted this way has a shorter growth cycle, guaranteed quality, and a very high survival rate. Another method is seed propagation, which is the most traditional planting method but also the most practical one. The best time for planting cuttings is spring and autumn each year, and new roots can grow about a week after cutting.
3. Reasonable Close Planting
After blood-amaranth survives, we need to thin the seedlings, even out the seedlings and fill in missing seedlings, so as to ensure uniform seedlings in the field. Generally, about twenty days after planting blood-amaranth, it can be transplanted and set out. At this time, the distance between each plant in the field should be kept at 35 cm, and the distance between each row should be kept at about 40 cm, and about 3,000 plants can generally be planted per mu. After setting out, we should reasonably spray carbendazim solution, which is beneficial for blood-amaranth to take root and establish roots.
4. Field Management
After blood-amaranth is set out, we should water it once, which can promote the growth of new roots and help it enter the seedling revival stage as soon as possible. During the growth of blood-amaranth, we should water frequently to keep the soil moist. About half a month after blood-amaranth is set out, we need to carry out the first topdressing, mainly with compound fertilizer applied in holes, combined with intertillage, and promptly clear the weeds in the field. In the later growth of blood-amaranth, we need to spray foliar fertilizer once about every ten days to ensure the quality of blood-amaranth. Finally, pay attention to the harm of aphids to blood-amaranth. Generally, dimethoate emulsifiable concentrate can be used for control, but it is best not to spray pesticide within half a month before harvest, otherwise it will affect the quality of blood-amaranth.
The growth cycle of blood-amaranth is very short, and it can generally be harvested in about fifty days, so we should pay attention to the harvest time to avoid harvesting blood-amaranth too late, which would affect its quality. After harvest, topdressing can be carried out to promote the growth of the next batch of blood-amaranth and increase its yield.
