Grain Amaranth

American grain amaranth (Amaranthus hypoch ondriacus), also known as Chiho Valley, belongs to a high-yield and high-quality feed and grain new crop in the amaranth family of the amaranth family. attach great importance to. Grain amaranth has the advantages of strong photosynthesis, rapid growth, high yield and eutrophication value, strong adaptability, heat resistance, drought tolerance, humidity tolerance, salt and alkali tolerance, and barren tolerance. It is a pig, cattle, sheep, rabbit, poultry, High-quality feed for fish.

Grain amaranth characteristics

High grass yield

During the peak period of growth, it can grow 5 ~ 7cm high in one day. The stems and leaves are luxuriant, which can be cut many times, and the yield of medium fertility fresh grass can reach 15000~20000kg/mu. It can be used as green fodder or sun-dried as grass powder fodder, which can play the role of replacing the material with grass.

Amaranth with high nutritional value has soft leaves, crisp stalks, good palatability, and timely harvesting of leaves can reach the standard of protein feed. The crude protein content is the most: 25% to 34% for leaves, 14% to 18% for stems.

Strong resistance and strong regeneration ability

Drought resistance; salt and alkali resistance; sand burial resistance; strong disease resistance; strong regeneration. After cutting or being broken by strong wind, it can quickly regenerate and recover, and it can cut 2 to 4 stubbles a year.

Low seeding rate

Grain amaranth seeds are small, with a thousand-grain weight of 0.5 ~ 0.7g, sowing amount is small, saving investment.

Easy to grow

When it enters the soil shallowly, it will sprout and grow when it rains, except for general farming. It is also suitable for plane sowing. Can be intercropped in young forests.

Key points of cultivation techniques

Grain amaranth seeds are small and require fine ground preparation. When preparing the land, apply foot fertilizer, and generally apply 2 000~3 000 kg/mu of decomposed organic manure before ploughing.

Grain amaranth does not require strict sowing time, and it can be sowed in spring, summer and autumn. Spring sowing in the north is from early April to late May, summer sowing can be in early and mid-June, and in the south from March to October. Sowing rate: 0.5 kg/mu for bacteria breeding, 1 kg/mu for sowing; the seeding is usually drilled, the row spacing is 30~35 cm, the sowing depth is 1~2 cm, and it is suppressed after sowing. Plant spacing of 10-15 cm is appropriate, and seedlings can also be transplanted. Weeding and thinning should be timely in the seedling stage.

Harvesting and feeding

Generally, pigs, poultry, and fish are cut at the height of 45~60 cm when feeding green pigs, harvested at the budding stage when feeding large animals, and cut at the blooming stage and fruiting stage when preparing hay and silage. Cut and leave the stubble 15-20 cm, and increase the stubble one by one so that new branches can grow from the newly left stalk nodes, but no stubble is left during the last cutting. It can be mowed 2 to 3 times a year, with 5-10 tons of fresh grass per mu. Grain amaranth seeds contain 14%-19% protein, and are rich in calcium and vitamin C, which can be used as high-quality concentrated feed. The stems and leaves are rich in crude protein, nitrogen-free extracts and minerals, and have low crude fiber content and good palatability. Its nutritional value is similar to that of alfalfa and corn seeds. It is a high-quality protein supplement feed. Cows fed 25 kilograms of grain amaranth green feed per day increased the milk yield by 5.19% compared with corn silage. Green feeding for fattening pigs can replace 20%-30% of concentrated feed. The proportion of hay powder in the diet of pigs and poultry can account for 10% ~ 15%, and the proportion of hay in the diet of rabbits is 30%. The feeding effect is good. Grain amaranth plants contain a lot of nitrate, which is converted into nitrite after being piled for 1-2 days after mowing, which is easy to cause nitrite poisoning after feeding. Therefore, the cutting quantity should be determined according to the feeding amount when green feeding, and the feeding must be finished on the same day after cutting.

Feeding method

Used as green fodder, green fodder, modulated hay or processed into grass powder and pellets, and used as leaf powder fodder.
