The pinyin of amaranth is [xiàn][cai], which is described in detail as follows:

1. Introduction of Amaranth:

Amaranth is a panicum miliaceum belonging to Amaranth family, which is green or red, and its leaves are oval rhombic or lanceolate, and its colors are green or red, purple or yellow, or some green is mixed with other colors. The whole flower is spherical, the flower is oblong, green or yellowish green, and the fruit is coffee-shaped oblong, wrapped in persistent petals. The flowering period is from May to August, and the fruit period is from July to September.

Amaranth originated in India, and was introduced to China as early as the 1th century. Now it is distributed in southern Asia, Central Asia, East Asia and other places, and cultivated all over China. Amaranth likes warm, humid and sunny climate conditions, avoids high humidity, summer heat and stagnant water, and has strong drought and alkali resistance, especially in fertile and loose clay soil. Amaranth breeds with seeds.

Amaranth is mainly used for invigorating qi, removing heat and dredging nine orifices. Cold-mixed Portulaca oleracea has the effects of clearing heat, promoting diuresis, astringing intestines and stopping diarrhea, and is suitable for people with damp-heat diarrhea in large intestine. Portulaca oleracea blooms in the sunshine and closes on cloudy days in the morning and evening, so it is named as midday flower of the sun. The flower language is silent love, light, enthusiasm, loyalty, sunshine and positive progress.

second, the growing environment:

Amaranth likes warm climate, has strong heat resistance, and is not cold-tolerant. The optimum growing temperature is 23-27℃, and the plants grow slowly below 2℃, and it is difficult for seeds to germinate below 1℃. Amaranth is a high-temperature and short-day crop, and it is easy to blossom and bear seeds under high-temperature and short-day conditions. Cultivated in spring with suitable temperature and long sunshine, the bolting is late, the quality is tender and the yield is high.

Amaranth is not strict with soil, but it grows well in alkaline soil, and it has certain drought resistance. It grows poorly in poorly drained fields, and sometimes escapes to semi-wild. Amaranth originated in India, and was introduced to China as early as the 1th century. Now it is distributed in southern Asia, Central Asia, East Asia and other places, and is cultivated all over China.

Amaranth is a leafy vegetable that is harvested in batches by sowing at one time. The first harvest is mostly combined with thinning seedlings, and it is usually harvested 3 to 4 days after sowing. When harvesting, we should master the principle of harvesting large crops and keeping small seedlings evenly, so as to increase the later yield.
