How to choose amaranth seeds? What are the methods of raising seedlings?

Grain amaranth, also known as thousand ears grain, is a kind of grain, feed, vegetable and ornamental dual-purpose, nutrient-rich high-yield crops. Amaranthus leaves are soft and rich in nutrients. All kinds of livestock like to eat them. They can be fed green or beaten. The straw and residual leaves after harvesting can be used for grazing or made into hay powder. How do you select seeds? What are the breeding methods? Let's take a look at it together with Xiaobian.

How do you select seeds?

Amaranthus seeds are small and need to be carefully prepared to loosen topsoil and retain water to create good conditions for sowing and emergence.

Before sowing, mechanical weeding and suppression are needed to control the sowing depth, ensure the uniformity of seedling emergence, and overcome the phenomenon of lack of seedlings and broken ridges.

2. What are the seedling methods of amaranth?

1. Sowing time

Amaranthus seed sowing time requirements are not strict, spring, summer, autumn can be sown. Spring sowing in the north can be done from early April to late May, summer sowing can be done in early and mid-June, and sowing can be done from March to October in the south. Sowing rate 0.4-0.5 kg/mu, sowing more by drilling, plant spacing 30×10 cm, sowing depth 1-2 cm, after sowing suppression, the average ground temperature of 18-24℃ when the seeds can germinate, in the seedling height of 8-10 cm (two-leaf stage) began thinning, 10-15 cm high (four-leaf stage) fixed seedlings, 20 thousand seedlings/mu. It can also be transplanted. Seedling intertillage 1-2 times, if the spring drought is serious, should be appropriate furrow irrigation to protect seedlings, bud irrigation once can increase production by more than 12%. After each cutting, dressing fertilizer had remarkable yield-increasing effect. The dressing amount of urea was 40 kg/mu.

Amaranthus seed seedling growth rate is slow, easy to be inhibited by other perennial weeds, but as long as proper management, seedlings quickly branched, mid-growth vegetative rapid growth, branching, lush stems and leaves.

2. Seedling cutting

Seedling transplanting method should be 15 - 20 days earlier than direct seeding, that is, hotbed seedling should be carried out in early May. Seedling height 15 cm; transplantable. This method has the advantages of rapid seedling growth, early ripening and seed production. The yield test shows that it is 20% higher than direct seeding. In the breeding, urban suburbs and towns have conditions for farm households to adopt hotbed breeding method. Seedling hotbed is to lay heat brewing material under the bed soil, and ensure the temperature required by seedlings through the fermentation and heat release of the heat brewing material. New techniques for raising seedlings by electric heating lines can also be adopted to ensure the required temperature for seedlings.

3. Seedling management

(1)Thinning and fixing seedlings. When the seedling height is 8 box meters-10 cm, that is, when the two-leaf stage, the seedlings should be thinned, and if there is a lack of seedlings, the seedlings can be replanted at any time, and the seedlings should be transplanted. The height of seedlings ranged from 15 to 6000 plants.

(2)Soil cultivation. Amaranthus plant tall, generally 1 m-1.5 m high, due to top-heavy light; easy to lodge, can be cultivated during intertillage to prevent lodging.

(3)Shoot the side branches. For grain amaranth fields with the purpose of harvesting seeds, it is best to knock off the lateral branches, and the branches and buds laid are high-quality feed for livestock and poultry. At the same time, ensure that the main inflorescences develop well, the main ears are large, and the seeds are full, which is beneficial to high yield.

The above is the introduction of grain amaranth, grain amaranth branch regeneration ability is strong, suitable for multiple mowing, after mowing by axillary buds issued new branches, rapid growth and flowering again. It is an ideal dry forage crop resource in the loess plateau and semi-arid and semi-humid sandy land in northwest China, and also an excellent forage crop in the coastal plain and inland secondary salinization area.
