Cultivation techniques of amaranth sowing in spring

Amaranthus tricolor, Amaranthus family, Amaranthus genus annual herb, stem stout, green or red, often branched, hairy or glabrous when young. Amaranth soft and smooth body and vegetable flavor, sweet entrance, there are Runchang stomach heat effect.

Amaranth leaves are rich in calcium, which is easily absorbed by the human body. They can promote the growth of teeth and bones, maintain normal myocardial activity and prevent intramuscular spasm. It is also rich in iron, calcium and vitamin K, which can promote coagulation.

Amaranth is rich in dietary fiber, often eat can lose weight, promote detoxification, prevent constipation. At the same time often eat amaranth can enhance physical fitness, contains higher than the eggplant, has "longevity vegetables" said.

Amaranthus can promote children's growth and development, its iron, calcium content is higher than spinach, fresh vegetables for the best. It is also suitable for anemia patients, women and the elderly to maintain normal myocardial activity, promote coagulation, hematopoiesis and blood oxygen carrying function.

Cultivation techniques of amaranth sowing in spring

Amaranth is cultivated as a vegetable. According to its leaf color, it is mainly divided into two categories: green amaranth and purple amaranth (red amaranth). The former has strong heat tolerance and is suitable for summer and autumn cultivation, while the latter has weak heat tolerance and is suitable for spring cultivation. In order to obtain high quality and high yield, the key techniques for planting amaranth in spring should be as follows:

1. selective seeding

In addition to flat terrain and convenient irrigation, amaranth land should be selected with less weeds to facilitate harvesting and improve market quality. Before sowing, plough the plot first, apply 1500 kg of human and animal manure per mu as base fertilizer, and then rake the flat ridge, and the ridge surface shall be finely divided and leveled. Because amaranth mainly eats young stems and leaves, it can generally be broadcast. The sowing density varies according to different seasons. In early spring, the temperature is low. In order to ensure high yield of seedlings, 3~5 kg should be sown per mu. Spread evenly, cover with a layer of plant ash or fine sand, and wet the surface of the bed (pay attention to avoid water splashing, so as not to wash away the seeds).

2. strengthen management

After sowing, pay attention to keep the soil surface moist. Generally early spring sowing about 7 days after emergence. After emergence, first of all, weeding should be carried out in time. When the seedlings grow two true leaves, the seedlings should be applied with 2.5 kg urea (diluted with thin human excrement); when the seedlings are about 7 cm high, 5~7 kg urea should be applied in combination with watering; when the seedlings are more than 15 cm high, they can be harvested. After each harvest, should be timely topdressing, with urea mixed with human excrement 0.1% urea solution for foliar fertilizer spraying, and pay attention to weeding.

3. Harvest by stages

Amaranth can be sown at one time and harvested in batches. Spring sowing peak harvest period in May ~ July, early harvest generally combined with thinning seedlings, should stay thin harvest density, stay small harvest big, keep seedlings to be uniform, in order to ensure late yield; late harvest can be used knife cut, leaving about 10 cm at the base, promote its germination of lateral branches, to be lateral branches grow to about 25 cm, cut again.
