Planting time of amaranth

Amaranth can be planted in both spring and autumn, and the planting time in open field is from late March to early August, and the planting time covered by greenhouse and small arch shed can be about 30 days earlier, and different varieties can be planted at different times. From late February to late March, sharp-leaf red rice amaranth and pointed-leaf red amaranth can be planted. From early April to late May: red amaranth, Dahongpao, white rice amaranth, willow amaranth and other varieties can be planted. From early June to early August: red amaranth, white rice amaranth, willow amaranth and other varieties can be planted.

Planting time of amaranth

Amaranth can be planted in both spring and autumn, and the planting time in the open field is from late March to early August, while covered with greenhouse and small arch shed, it can be planted 20-30 days earlier, so it can be planted in late February, and greenhouse planting can be put on the market for about 30 days in advance. In addition to planting in early spring, generally planting can be on the market for about 35 days.

2. Varieties suitable for planting in different periods

1. From late February to late March: sharp-leaf red amaranth, pointed-leaf red amaranth and other varieties.

2. From early April to late May: red amaranth, Dahongpao, white rice amaranth, willow amaranth and other varieties.

3. From early June to early August: White rice amaranth, willow amaranth, red amaranth and other varieties.

3. Planting methods of amaranth

1. Soil preparation and fertilization

The main results are as follows: (1) amaranth does not have high requirements for soil, so it can be planted in alkaline soil with flat terrain, convenient drainage and irrigation and less weeds. the seeds of amaranth are relatively small, so it is necessary to plough the soil flat and soft.

(2) amaranth likes fertilizer. Before ploughing the soil, 3000 jin of high-quality mature manure and urine can be applied per mu, and then furrows or ridges can be made, and the sowing amount can be determined according to the sowing time. The earlier the sowing time is, the more seeds will be used. The sowing amount per mu in early spring is 8-10 jin, sowing or strip sowing can be chosen, and the soil should be covered with 0.5-1cm after sowing.

2. Topdressing and watering

After sowing in early spring, it is necessary to wait for about 7-12 days before the seedlings will grow. The first topdressing can be carried out at the 3-5 leaf stage of amaranth, 20 jin of urea per mu can be applied, and the second topdressing can be carried out 12 days later. After the first harvest of amaranth, the third topdressing is carried out. During each harvest, fertilizer needs to be applied once, and nitrogen fertilizer is mainly applied. If quick-acting nitrogen fertilizer is applied, it can be carried out with watering. But water less after sowing in spring.

3. Ploughing and pruning

During the seedling growth period, timely ploughing and weeding should be carried out to promote the robust growth of amaranth. Amaranth should be pruned if it is harvested many times. After the main branch is harvested, 2-3 nodes can be retained at the base, which is beneficial to promote the germination of lateral branches and increase the yield.

4. prevention and control of diseases and insect pests

The disease resistance of amaranth is relatively strong, and the common disease is white rust. During this period, it can be controlled by strychnine or mancozeb, common pests are aphids, and imidacloprid or aphid fog can be used during this period.

5. Timely harvest

The main results are as follows: (1) the amaranth can be harvested in batches after sowing once, and the seedlings can be harvested at the same time at the first harvest, generally about 42 days after sowing, when the seedlings grow to 10-12cm and the number of leaves is 5-6, the interplant harvest can be carried out continuously, which can follow the principle of large harvest and uniform seedling, which is beneficial to increase the yield in the later stage.

(2) after amaranth harvest, topdressing should be carried out in time, and amaranth generally feeds on tender leaves, so it needs to be harvested in time, otherwise it will cause an increase in fiber and poor quality, and the yield per mu can be as high as 2000-3000 jin.
