How to plant amaranth

Amaranth is a warm vegetable, so it is common in summer. At present, it is widely distributed in our country. Amaranth tastes very good, so there are a lot of buyers. There are also a lot of people who want to grow it. There are many ways to grow it. If you want amaranth to grow well, technology is important.

How to grow amaranth

1. Seed soaking and sprouting: amaranth seeds are soaked in cold water for 24 hours and need to be scrubbed several times in the process of seed soaking to facilitate water absorption. Remove the soaked seeds in winter and early spring, scrub them with clean water, remove and drain water, wrap them with gauze with good permeability, cover them with wet towels, accelerate germination under the condition of 15-20 ℃, and sow when 30-50% of the seeds are white. It is cultivated by direct sowing in other seasons.

2. Soil preparation and fertilization: amaranth cultivation should choose plots with few weeds. Although amaranth does not have strict requirements for soil, it is better to have loose, fertile and good soil for fertilizer and water conservation, and amaranth likes alkaline soil. 5000 kg of mature organic fertilizer and 50 kg of 25% compound fertilizer are applied per mu, and intensive cultivation is made into a high border with a width of 1 to 1.2 meters, a width of 0.3 meters and a depth of 0.15 meters.

3. Sowing method: the seed of amaranth is small, sowing mixed with some fine sand or fine soil can make the sowing uniform, the amount of seed per mu is 0.25kg to 0.5kg. Can be flat bed sowing or strip sowing, sowing can use four-toothed rake shallow hug or not, strip seeder can be a little deeper in spring, summer should be shallow, shallow cover soil, and then suppress, can be watered, waiting for seedlings. In winter and early spring, cover with a thin layer of straw to moisturize, and then cover with a layer of plastic film to keep warm. Add sunscreen in summer.

Planting technique of amaranth

1. Cultivation season and mode: amaranth is a temperature-loving and heat-resistant vegetable, which can be cultivated in frost-free period from spring to autumn, late bolting and flowering in spring sowing and tender quality. Sowing in summer and autumn is easy to bolting and flowering, and the quality is old. The open field in North China and Northwest China is sown from late April to early September, and harvested from late May to early October. The growing period is 30-60 days.

2. Cultivation techniques: land preparation and bed preparation: the cultivation of amaranth should choose plots with flat terrain, convenient drainage and irrigation and less weeds. Harvesting seedlings, tender stems and leaves are generally sown, ploughing depth is 15 cm before sowing, and 15002000 kg of rotten organic fertilizer is applied per mu. The quality of soil preparation is high, and the soil on the border must be fine and smooth, otherwise it will affect the seedling emergence rate and seedling evenness.

Fertilizer and water management of amaranth

It takes about 7-12 days to pick up seedlings at dusk sown in early spring, and it takes only 3-5 days for amaranth sown in late spring and summer and autumn because of high temperature. During the period from sowing to seedling emergence of amaranth, if the weather is dry, water frequently and keep the border moist. During the growth period of amaranth, in addition to applying base fertilizer, it is necessary to apply topdressing in time in order to obtain high yield. When the seedlings had two true leaves, the first topdressing was carried out and 10-15 kg of ammonium sulfate was applied per mu. The second topdressing was carried out 10-20 days later. The type and quantity of fertilizer are the same as those of the first topdressing. After each harvest, topdressing should be applied in time, and quick-acting nitrogen fertilizer should be better, and should be watered after each topdressing. The amaranth sown in dry and spring should control the water properly in the early stage, and the fertilizer and water should be sufficient in the later stage. Whenever the amaranth is sown, it shows exuberant vegetative growth under the condition of sufficient fertilizer and water.

Pest control of amaranth

1. Amaranth white rust: the main disease of amaranth is white rust, which can be prevented by spraying 75% chlorothalonil wettable powder 1000 times or 77% trichlorothalonil 1500 times liquid leaves at the seedling stage, combined with manual leaf picking for chemical control at the initial stage of the disease, but do not spray immediately on the day after each harvest, so as not to affect the quality of the goods.

2. Root-knot nematode disease: the diseased body should be removed in time after harvest in the seriously diseased area, and it can also be rotated with lily vegetables or rotation of flood and drought. When sowing or planting, ditch or hole application of 10% miku granules, 75 kg per hectare. During the growth period, the roots can also be irrigated with 200-fold solution of methyl isosinophos emulsion for 1 or 2 times.

When planting amaranth, we need to make a good seed selection, and then choose the appropriate time to sow. Amaranth is resistant to high temperature but not to stagnant water, so it is necessary to do a good job in field drainage technology when planting, so as to avoid death caused by stagnant water. In the later stage, fertilizer and water management and pest control should also be done.
