Detailed Explanation of the Latest High-Yield Cultivation Methods for Black Nightshade

Black nightshade is an annual plant that produces round black berries, and the entire plant can be used as medicine, including the fruit. It belongs to the juicy berry category. It grows over a wide range in the wild and is easy to grow. It spans from temperate to tropical zones. Black nightshade is easy to keep alive and is very suitable for artificial cultivation. However, if you want a high and abundant yield, some methods and techniques are still needed in cultivation. You cannot just leave it alone. You can learn about these specific methods right away.

1. Planting density

Generally, planting should be done sparsely without wasting soil resources, not too densely. In summer, with high temperatures and frequent rain, drainage is inconvenient, air humidity is relatively high, and a closed canopy worsens disease. When plants are crowded, manual farming operations can easily damage the plants or cause the plants to touch each other and spread disease. Generally, about 3000 seedlings are planted per mu. Roughly one plant per hole, with 30 cm row spacing and 30 cm plant spacing.

2. Thinning and weeding

After the seedlings emerge and grow to the 3-leaf stage, crowding will occur. At this time, you must thin the seedlings, removing small seedlings, weak seedlings, and a few diseased seedlings. Leaving the robust seedlings is enough to maintain the remaining growth. During thinning, be careful to pull out nearby weeds, and also remove weeds between the rows. Prevent weeds from growing up and clogging the rows.

3. Topping

Topping: for plants without an obvious main trunk, when the main branch grows to sufficient length, top it to encourage side branches. When the side branches grow to a certain extent, top them again, thus encouraging full branches throughout the whole plant. In this way, after the tender shoots grow, you can pick more tender shoots. You can pick tender shoots for eating many times. Every time side branches form, fertilize promptly to ensure nutrition. The number of side branches determines the yield.

4. Topdressing and watering

Generally, after each harvest of tender shoots, apply fertilizer once to supplement nutrition. Use quick-acting chemical fertilizer, which can quickly supplement nutrition. Generally, about 30 jin of nitrogen fertilizer urea and 35 jin of compound fertilizer. If there is time, you can spray potassium dihydrogen phosphate and the like. Maintaining leaf nutrition will make the taste much better and improve the plant's resistance.

5. Harvesting

Since the main harvest during the growing period is tender shoots, when harvesting, be careful with the harvesting node, do not damage the stems and leaves, minimize the damage, and allow recovery as quickly as possible. Only harvest the first node below the tender shoot, do not harvest excessively, harvest gently, and do not pull hard. Do not bruise the plant.

This harvesting method for black nightshade determines that during the cultivation process, topdressing must be done many times to maintain nutrition, maintain plant vigor, and extend the harvesting period. Then
