Planting Methods and Pest and Disease Control for Yam Varieties Suitable for Soup

When it comes to winter nourishing foods, yam is indispensable. Yam can also be called Chinese yam, huai yam, huai shan, and white yam. Each region has a different name for it. As a food with high efficacy and value, yam can aid digestion and also treat coughs. As market demand grows day by day, yam growers are also gradually increasing in number. So, are you clear about the planting methods for yam?

Planting Methods for Yam

1. Land selection

The first step in planting yam is, of course, choosing suitable land; selecting a plot of fertile, loose soil with good drainage is key. Sandy loam and clay soil without standing water are relatively suitable for cultivating yam. When winter comes, it is time to start the preparatory work. Carry out winter plowing of the land, apply base fertilizer well, and then deep plow. When spring comes and flowers bloom, shallow plowing can be done. Before each sowing, remember to water after fertilizing is completed, giving the land enough moisture, which is more favorable for subsequent growth.

2. Seed piece treatment

The treatment of yam seed pieces is relatively crucial. Within twenty days before planting, you can select some root heads without disease characteristics as seeds. Then sun them until cracks appear. When sunning the seeds, be careful to handle them gently and do not use force. If heavy rain or bad weather occurs, do a good job of waterproofing.

3. Pest and disease control

Yam pests and diseases mainly have two typical ones: anthracnose and brown spot disease. Anthracnose appears more often during the rainy season, harms stems and leaves, and leaves some brown spots or black spots on the stems and leaves. When encountering anthracnose, you can soak the roots in Bordeaux mixture for 10 minutes, then clean up the field weeds and dead branches and dry leaves. When encountering brown spot disease, everyone should not panic either. Brown spot disease is mostly concentrated on rainy days; there is more standing water on rainy days, which harms yam leaves. It is similar to anthracnose, in that brown black spots appear on the leaves, causing the leaves to perforate. You can clean more during daily management and keep the garden tidy. Using a mixture of zineb and dinitro can effectively protect them.

4. Harvesting and processing

Harvesting yam is a technical job. What needs attention is that the yam must not be broken, as this will affect sales. Do not clean off the soil on the surface of fresh yam completely; it can play a role in preserving freshness. If selling to large supermarkets or restaurants, after washing clean, plastic film can be used to cover it, which can prevent moisture and mold. Processing yam must be carried out according to the requirements of the buyer. No matter which processing method is used, the principle of hygiene and cleanliness must be followed.

That is today's summary about yam for everyone. The nutritional value of yam is obvious to all. It can not only enhance freshness in soup but also be cooked alone to make delicious food. Growing yam still has very good prospects.
