Planting Methods and Key Technical Points for Black Nightshade
Black nightshade is a wild medicinal herb; both its roots and its berries have certain medicinal value. It can basically be found in relatively fertile and moist places in rural areas. In the past, people in rural areas said that black nightshade berries could not be eaten and would cause poisoning. Indeed, black nightshade berries themselves contain a certain toxicity, so they must be processed at high temperatures before they can be eaten. So today let us take a look at how this thing, once called poison by rural people in the past, is planted.
1. Seed Selection and Site Selection
Obtaining and selecting black nightshade seeds is actually very simple. Although black nightshade seeds are also available for purchase now, those seeds are still not as good as wild ones. Wild ones grow relatively fast, have strong reproductive capacity, and have a long edible lifespan, so when selecting seeds, try as much as possible to choose wild seeds. You can find them yourself in some fields and small paths in rural areas. When planting, try as much as possible to choose relatively moist black soil for planting, so that black nightshade grows faster.
2. Land Preparation and Fertilization
When preparing the land, plow as deeply as possible, as this can prevent some hidden diseases. After preparing the land, spread a layer of fertilizer and then plow the land again. Finally, make furrows and ridges, sun the soil, and wait for sowing.
3. Sowing and Raising Seedlings
For sowing, direct sowing can be used, but this will result in many places where black nightshade does not sprout and the field being uneven, so the most commonly used method is transplanting. Before sowing, first wet the seedbed, and then sowing can be carried out. When sowing, sow as thinly as possible, so that the seedlings that grow later will be relatively sturdy, making them easier to survive when transplanted. From after sowing until emergence, water continuously. You can cover the soil surface with a layer of grass, which can maintain the temperature in the soil. When the seedlings grow to six or seven centimeters, they can be transplanted.
4. Field Management
When transplanting, pay attention to reasonable density, generally with each plant spaced thirty to fifty centimeters apart. After transplanting, water the black nightshade seedlings and continue until they survive. After they survive, start promoting seedling growth, mainly by spreading some urea, so that after the seedlings grow to a certain extent they will flower. When black nightshade flowers, the nutrients required account for seventy percent of its growth process. To ensure fertility, generally potassium fertilizer and phosphorus fertilizer are used, or farmyard manure is also acceptable.
5. Harvesting Method
Black nightshade can generally be harvested for three to four months a year. After black nightshade matures, it can be picked, leaving some new branches and leaves at the bottom, and then applying some urea to promote the growth of branches and leaves. When it matures, harvest in the same way, so that black nightshade can be harvested continuously without stopping.
The above is a simple introduction by Qinnong Network to the planting methods of black nightshade. We hope the new planting techniques can help everyone better understand black nightshade. At the same time, if you have any better suggestions, you are welcome to discuss them together with the editor.
