How to plant amaranth for high yield

Amaranth was originally a kind of wild vegetable in China, and it has gradually become the main cultivated variety in vegetable field with the passage of time. The growth ability of amaranth is very strong, with strong drought and moisture tolerance. There is a wide range of cultivated areas in our country, and now the main reason for planting amaranth is to produce. So how to grow amaranth in order to produce high yield? Let's take a look at it with the editor.

1. Planting time

Before planting, we should first select the planting varieties, the common amaranth varieties are green amaranth, red amaranth and other varieties. We should choose a good variety reasonably according to the season, planting area and environment. The planting time of amaranth is usually in spring, and it is harvested and listed after maturity in summer. However, the main thing is to control the time according to the mode of cultivation. If it is planted in open field, it can be planted from March to August. If it is a greenhouse seed, then the planting time can be appropriately increased by about 3-4 weeks. And the use of greenhouse planting can also improve the time to market, about a month after planting can be harvested.

2. Sowing seeds at the right time

After the variety is selected, the seeds should be accelerated and disinfected. First, the seeds should be soaked in water for about 20 hours. Promote seed water absorption, improve seed germination rate, when about 40% of the seeds germinate, they can begin to sow. When sowing, it is necessary to do a good job in soil preparation, the soil is mainly with good drainage and irrigation capacity and strong water retention, and the application of rotten farm manure to improve soil fertility. When sowing, we should pay attention to control the depth, not too deep and too shallow, cover the soil and water after sowing, and then cover a layer of straw to improve the heat preservation and water retention of the soil.

3. Strengthen the management

After planting, it is best to build a small arch shed in the field to improve the heat preservation capacity of the field, when the temperature is relatively low, cover a layer of straw on the arch shed, raise the temperature to prevent low temperature from affecting the growth of amaranth. Then we should pay attention to do a good job of fertilizer and water, and keep a certain amount of water content in the soil when planting in spring. Increase the amount of water appropriately as the temperature rises, but be careful to avoid higher temperatures such as noon. When fertilizing, we should pay attention to control the amount of nitrogen fertilizer, especially nitrogen fertilizer, not too much nitrogen fertilizer to prevent the excessive growth of amaranth.

4. Pest control

The disease resistance of amaranth is relatively poor, so we should also pay attention to the prevention and control of diseases and insect pests when planting. The common diseases and insect pests of amaranth are white rust, stem rot and root-knot nematode. These diseases and insect pests will harm various parts of amaranth in varying degrees, resulting in a decline in yield, and the planting efficiency will also be greatly affected. When planting, we must strengthen management, disinfect regularly, do a good job in fertilizer and water work, often observe, find out the cause in time when there is an abnormal situation, and then take corresponding measures.

The above is a brief introduction to how to grow amaranth for high yield. In fact, if you want high yield of amaranth, the most important thing is to do a good job of management. Strengthen management, meet the demand of amaranth for water and fertilizer, promote the growth of amaranth, in order to effectively increase the yield. That's all for today's introduction.
