You should pay attention to several aspects when cultivating solanum nigrum: the ambient temperature should be between 22 and 30 degrees; the soil should be rich in organic matter and fertility; the light should be sufficient and cannot be without light for a long time; watering should be especially appropriate, and the amount of water should be controlled in winter; fertilization About once every ten days. In addition, prune and top them regularly to promote growth and development.

1. Basic introduction

1. Basic introduction

Solanum nigrum belongs to the annual herbaceous plant of the Solanaceae family. It is also called bitter cold vegetable and diangui vegetable. It is mainly distributed in southern my country such as Yunnan, Guangxi and other places. Nightshade with few flowers is a delicate herbaceous plant, about 100 centimeters tall, with basically five hairs on the rhizome, oval leaves, white umbrella-shaped inflorescences, smaller flowers, and black-purple spherical fruits.

2. Maintenance methods

1 .Temperature: Nightshade with few flowers is suitable for growing at a temperature of 22 to 30 degrees Celsius, and when it blooms, it is suitable for a temperature of 15 to 20 degrees Celsius.

2. Soil: Solanum nigrum has higher soil requirements, but it needs to grow in soil with rich organic matter, moisture and fertility to make it grow well. If it is grown in clayey soil with poor ventilation and insufficient organic matter, it will easily lead to stunted growth.

3. Light: Solanum nigrum prefers a well-lit environment. It is shade tolerant, but cannot be left out of light for long periods of time. During its growth and flowering periods, it needs to have enough sunlight, but not too much light.

4. Watering: Solanum nigrum must be watered appropriately. It is afraid of both waterlogging and drought, so the amount of watering must be controlled. When it is colder in winter, you need to pay more attention to controlling the amount of water.

5. Fertilization: For small-flowered nightshades planted in large areas, fertilization is basically sufficient once every ten days. Fertilization is mainly foliar fertilizer, and additional fertilization is required after harvesting.

1 .Seedling propagation: Solanum nigrum has higher soil requirements, so it is necessary to choose a relatively fertile, organic matter-rich, and loose soil as a seedbed. Water thoroughly before sowing, then mix the seeds with fine sand and mix evenly. After sowing, cover it with a layer of soil about 0.5 cm thick. Keep the soil moist enough to allow seedlings to emerge in about 5 to 7 days.

2. Pruning and topping: When the plant grows to approximately 8 to 10 nodes, the top center can be removed to allow sufficient space for the side buds to grow. Wait until the lateral buds are about 20 centimeters long before pruning them, leaving only five centimeters to promote the growth of new branches. Dead leaves, etc. also need to be removed in time.

3. Appropriate top dressing: In order to keep the new branches fresh and tender and encourage them to continue to grow new buds, top dressing needs to be carried out after each harvest to promote their growth and development. This can also enhance its disease resistance and improve the quality of Solanum nigrum.
