What is the planting method and time of amaranth?

Amaranth contains more minerals such as iron and calcium, as well as carotene and vitamin C. it has strong resistance, easy growth, heat, drought and moisture tolerance, and less diseases and insect pests, so it is one of the main green leafy vegetables in summer. So, what is the planting method and time of amaranth?

What is the planting method of amaranth?

1. Land selection and preparation

Amaranth has strong adaptability to soil, and it can choose clay or sandy soil with flat terrain and convenient drainage and irrigation, and alkaline soil is the most suitable. Apply base fertilizer before soil preparation, apply rotten organic fertilizer 2000kg per mu, turn deeply after fertilization, make a border after turning, and make a ridge with soil, the height of the border is 10cm, the width of the border is 1m, and the length of the border is determined according to the plot. After making the bed, the bottom fertilizer should be applied once, and the compound fertilizer with nitrogen, phosphorus and potassium content of 15:15:15, 50kg per mu. Spread evenly to avoid excessive local fertilization and seed burning. Scrape the soil with a rake and mix the soil with fertilizer evenly. Because the seeds of amaranth are small, the soil is fine when raking, which is conducive to seedling emergence.

2. Sowing seeds

Because the seeds of amaranth are small and only 4 times the size of sesame seeds, it is not easy to spread evenly. In the process of long-term sowing, a practical sowing method is summarized, in which fine sand and seeds are mixed evenly according to the proportion of 1:5 before sowing, and then sow directly on the ground. The amount of pure amaranth seeds per mu is about 0.6kg, rake the border surface with a rake after sowing, so that the amaranth seeds are covered with a layer of soil, and then step on the border surface to prevent the seeds from being washed away during watering, resulting in uneven germination.

3. Watering

When watering, spray water should be sprayed to prevent the border surface from flushing out of the pit and to prevent excessive water from washing away the seeds. After all the water has infiltrated into the soil, cover the border with plastic film, and compaction with soil around the plastic film can promote seed germination as soon as possible, and amaranth does not need watering before emergence.

4. Weeding

As the amaranth seedlings are small, as long as more than ten days, weeds will be much higher than the seedlings, must be pulled out in time, otherwise compete with amaranth for nutrients, affecting the lighting of amaranth.

5. Fertilization

About 20 days after sowing, topdressing was carried out for the first time when the seedlings grew more than 2 leaves. Choose sunny day, apply ammonium sulfate 15kg per mu, and water it in time after fertilization. The second topdressing was carried out at intervals of 12 to 15 days. Apply fertilizer for the third time after the first harvest, the usage is the same as above, in order to promote the growth of smaller amaranth after harvest, pay attention to timely watering after each fertilization and pull out weeds.

6. Pest control

Han cuisine has strong disease resistance, and the main disease is white rust, which can be controlled by strychnine or mancozeb. The main pest is aphid, which can be controlled by imidacloprid or aphid spray.

7. Harvest

Amaranth is sown and harvested in batches. The harvest should be timely, the first harvest should be combined with inter-seedling, when the seedling is 10-12cm high and has 5-6 leaves, it should be harvested one after another, mastering the principle of large harvest, leaving small and uniform seedling, and topdressing in time after harvest.

2. Planting time of amaranth

The growth cycle of amaranth is not long, usually 40-45 days. It can be planted from spring to autumn, sowing in open field from March to August, and planting in greenhouse and small arch shed can sow about 20-30 days earlier.

The planting method of amaranth is not difficult, and it can be sown in spring and autumn. Planting under the condition of sufficient water and fertile soil is more beneficial to improve the yield and quality.
