Planting Methods and Key Technical Points for Davallia

Davallia is an epiphytic fern of the family Davalliaceae, and its main medicinal value lies in its rhizome. Its primary effects are strengthening bones, tonifying the kidney, dispersing blood stasis and relieving pain, and rejoining bones and tendons, and it is commonly used to treat symptoms such as toothache, lower back pain and chronic diarrhea. At present it is mainly cultivated in parts of Liaodong, Shandong, Jiangsu and Taiwan, China. So how do you plant Davallia artificially? Let us learn its planting methods together below.

1. Land preparation and fertilization

Davallia has the characteristics of preferring shade, moisture and coolness, and avoiding strong light, so it generally grows in environments with ample rainfall and high air humidity. The planting site is usually chosen in shaded areas, under forest, in valleys and similar places, and the soil should be rich in humus, with a sandy gravel texture. Planting requires complete clearing of the land and deep plowing, removing weeds, tree roots, insect eggs and so on from the planting site, breaking up and raking the soil level, and applying sufficient farmyard manure and mixing it evenly. Finally, dig trenches with the trenches interconnected to facilitate water management.

2. Propagation methods

There are three propagation methods for Davallia, namely division propagation, rhizome propagation and spore propagation, among which rhizome propagation is the main one. The best planting time for division propagation is May and June, mainly separating the mother plant into sections of four to five cm each, placing them in a cool place, and planting them after they sprout. Spore propagation involves collecting mature spores of Davallia and letting the spores reproduce and grow, but the spore germination rate is low, so scientific spore treatment is needed. Finally, rhizome propagation only requires selecting thick, plump-budded rhizomes, then cutting them into sections of about fifteen to sixteen m, and planting them at a row spacing of 45 cm and a plant spacing of 40 cm.

3. Field management

Since Davallia is a plant that prefers shade and avoids strong light, we need to carry out scientific field management according to this characteristic. First, if the light at the planting site is too strong, we need to promptly set up a shade shed for shading, and the optimal shading level is about 50 percent. Second, at least three to four cultivations and weedings are needed each year, but shallow cultivation is generally used so as not to affect the normal growth of Davallia.

4. Cultivation techniques

The most important cultivation techniques for Davallia are water management and fertilization. Davallia has relatively high requirements for soil moisture and air humidity, so we should water frequently to maintain the humidity in the growing environment. If the leaves of Davallia are found to be withering, you can soak it in water and spray the soil with water. If after one day there is still no recovery of growth, then the withered parts need to be cut off. As for topdressing Davallia, we mainly focus on applying base fertilizer to ensure sufficient humus content, and second, appropriately topdress with nitrogen, phosphorus and potassium fertilizers.

The above are the artificial cultivation techniques for Davallia. In fact, as long as the planting conditions generally meet the standard and water management is accurate, there is no great difficulty in achieving successful cultivation.
