The Latest Cultivation Techniques and Methods for Digupi: A Tutorial
Digupi, also known as Chinese wolfberry root bark, is the root bark of the Chinese wolfberry (Lycium chinense). It can be used as medicine and has the effects of reducing fever, cooling the blood, and clearing the lungs to reduce internal heat. It is fairly widely used and is distributed across most regions of our country. So how should Digupi be cultivated? Let's take a look together.
1. Growth Habits
Digupi often grows on hillsides, wasteland, hilly land, saline-alkali land, or by roadsides at the edge of villages. It is not strict about soil requirements, and ordinary soil can be used for planting, but loose, fertile, well-drained neutral or acidic loam is preferable. Strongly alkaline soil, clay loam, and low-lying, easily waterlogged land are not suitable for planting. When planting, apply base fertilizer in combination with land preparation, level and harrow the soil, and then make beds or ridges while waiting to plant.
2. Propagation Methods
Digupi can be propagated by seed or by cuttings. For seed propagation, select seeds of excellent quality; after harvesting in summer, soak them in warm water, rub the seeds, wash them clean, and dry them in the shade for later use. Before sowing, place them in a greenhouse to promote germination. When one third of the seeds have broken white, they can be sown. When sowing, open shallow furrows on the bed surface at a row spacing of 40 cm and sow the seeds evenly. For cutting propagation, take lignified one-year-old branches of 0.3 cm or more from excellent mother plants, cut them into 45-20 cm lengths, and then insert them for cuttings at a plant spacing of 5-10 cm diagonally in the furrows, then firm the soil by treading it down.
3. Field Management
For plants propagated by seed, after emergence, pay attention to watering according to soil moisture conditions, and loosen the soil and weed in a timely manner to promote seedling growth. When the seedlings grow to 6-9 cm, thin them in a timely manner, and when the root diameter of the seedlings is 0.7 cm, they can be transplanted. After transplanting, also cultivate and weed in a timely manner to promote root growth and development, and fertilize at the same time. In October to November, apply decomposed farmyard manure as base fertilizer, while in May to July, apply topdressing twice: the first time with urea, and the second time with phosphate and potassium fertilizer to increase yield. At the same time, pruning of young trees should also be done well to encourage more branching and the early formation of a canopy.
4. Pests and Diseases
The main diseases are black fruit disease and root rot. Black fruit disease damages flowers and fruits; spraying Bordeaux mixture when fruits form, or spraying Tuzet after rain, gives relatively good control. Root rot can be controlled by spraying thiophanate and carbendazim to irrigate the root system. The main pests are Chinese wolfberry fruit fly and lily leaf beetle. For Chinese wolfberry fruit fly, during overwintering, scatter Sevin powder in the field for control, or in autumn and winter irrigate or deep-plow to kill overwintering pupae. For lily leaf beetle, irrigate in spring to kill the source of the insects, or spray trichlorfon during an outbreak of the pest for control.
