Detailed Guide to the Latest Cultivation Techniques and Methods for Fringed Pink (Dianthus superbus)
Fringed pink, also known as Gaoshan, is a perennial herb of the genus Dianthus. The whole plant can be used as medicine and has effects such as clearing heat, promoting urination, and breaking blood to free menstruation. It grows across the Eurasian continent. At present, because wild resources are scarce and demand is relatively high, artificial cultivation is carried out in many regions. Below, let us take a look together with the editor.
1. Site Selection and Land Preparation
Fringed pink grows on hillsides, grasslands, roadsides, and under forests. It has no strict requirements for soil, and generally any plot can be used for planting, but well-drained, fertile, loose sandy loam is preferable. After selecting the planting site, combine this with plowing and apply 1500-2000 kg of decomposed farmyard manure, 15-20 kg of superphosphate, and 50 kg of plant ash per mu as base fertilizer. Rake it fine and level it, then make beds. The bed surface should be between 1-1.3 m, and drainage ditches should be made between beds.
2. Propagation Methods
The propagation methods for fringed pink are mainly seed propagation and division propagation. Seed propagation uses direct sowing and can be done in spring or autumn. Spring sowing is generally around Qingming in March-April, while autumn sowing is generally in July. Drilling or hole sowing can be used. For drilling, open furrows on the bed surface at a row spacing of 30 cm, evenly scatter the seeds into the furrows, cover with soil, and water. Generally, one jin of seed is used per mu. For hole sowing, open holes on the bed surface at 30×20 cm, and place a certain number of seeds in each hole. Division propagation is carried out around Qingming. During the rainy season, dig out the plant's tuberous roots, divide them into 3-4 plants, and transplant them separately. On the bed surface, dig holes at the spacing used for hole sowing, plant one plant per hole, then cover with soil, press firm, and water.
3. Field Management
If the drilling method is used, thin the seedlings in time when the seedlings grow to 5 cm. If the hole sowing method is used, keep 5-7 strong seedlings per hole. After the seedlings are established, cultivate and weed in time to ensure there are no weeds in the field and promote root growth of the seedlings. During the growth of fringed pink, topdressing is generally carried out 3 times each year, each time applying 1000 kg of human manure and urine or 15~20 kg of ammonium bicarbonate per mu to promote rapid plant growth and development. During cultivation, pay attention to controlling soil moisture. Too much or too little water is unfavorable to the growth of fringed pink. During drought, water frequently to keep the soil moist. After rain, drain promptly to avoid root rot.
4. Pests and Diseases
The main diseases of fringed pink are root rot and smut. Root rot mainly damages the root system, causing root decay and plant death. After diseased plants are found, remove and burn them promptly, and spread lime powder on the diseased holes and surrounding area for disinfection and sterilization. Smut mainly damages inflorescences and fruits, causing abnormal growth of inflorescences and fruits. When sowing, the method of scalding seeds with hot water can be used to eliminate pathogens on the surface. The main insect pests are green caterpillars and armyworms, which can be killed with fenitrothion emulsifiable concentrate.
