Detailed Explanation of Solanum lyratum Planting Techniques and Cultivation Management Methods
Solanum lyratum is a herbaceous vine in the Solanaceae family. The whole plant or the root can be used as medicine, and it is said to have the effects of clearing heat and detoxifying, draining dampness and reducing swelling, and fighting cancer. It is often used for conditions such as colds and fever, breast abscess, malignant sores, and rheumatic arthralgia. So how should Solanum lyratum be planted? Let's find out together.
1. Site selection and land preparation
Solanum lyratum prefers a warm and humid environment. It is not strict about soil requirements, but sandy loam with deep soil layers, loose and fertile texture, and rich organic matter is ideal. Saline-alkali land, low-lying land, and heavy clay land are all unsuitable for planting. After selecting the site, plow and harrow carefully. In combination with land preparation, apply base fertilizer: 5000 kg of farmyard manure, 20 kg of urea, and 50 kg of phosphate and potassium fertilizer per mu. Spread them on the ground, mix them evenly with the soil while turning it over, then make high beds and wait for planting.
2. Propagation methods
Solanum lyratum can be propagated by seed, cuttings, and division. Seed propagation is further divided into two steps: sowing and transplanting. Sowing can be done in spring or autumn. Spring sowing is around Qingming, and autumn sowing is before the soil freezes. First open shallow furrows on the bed surface, sow the seeds evenly, then cover with soil and water. Strengthen management after seedlings emerge, and they can be transplanted after one year of cultivation. For cuttings, select vigorous branches with no pests or diseases that have grown for 1-2 years as cuttings. Cut them into about 20 cm lengths, soak them in rooting powder, and then insert them into the ground, leaving one third above the ground. Division propagation is generally done in autumn. Expose the underground rhizomes of the plant above the topsoil, cut and wound them, then cover with soil. In the following spring, new seedlings will sprout, and they can be dug out and transplanted at that time.
3. Field management
After the seedlings emerge completely, cultivate and weed in time to promote root growth of the seedlings. Water during drought to meet the needs of the plants, and drain promptly after the rainy season to avoid root rot. When the seedlings grow to 30 cm, set up supports and let the stems and vines climb, which can increase ventilation and light penetration in the field. After the first harvest, apply topdressing in time once, so as to help it recover as soon as possible. After that, apply topdressing promptly after each harvest.
4. Pests and diseases
Solanum lyratum has strong environmental adaptability and very few diseases. When diseases occur, conventional control methods are sufficient. The main pests are red spider mites and aphids, which suck the young and tender parts of the plant, causing slow or stopped growth and great damage. In addition, underground pests gnaw the roots and stems, and in severe cases cause plant death. Red spider mites can be controlled with propargite; aphids can be controlled by spraying dimethoate; underground pests can be trapped and killed with phoxim made into poison bait.
