How to Grow Morinda officinalis? A Detailed Guide to the Latest Planting Methods
Morinda officinalis is a relatively commonly used traditional Chinese medicinal herb, mainly used for tonifying the kidney, supplementing yang, strengthening the sinews, fortifying the bones, and dispelling wind-dampness. The Morinda officinalis on the market today is divided into wild and cultivated types, but at present the wild plants mainly grow in Guangxi, Guangdong, Hainan and other regions with a relatively warm climate all year round. Cultivated planting, on the other hand, is mainly carried out in the Guangdong and Guangxi regions. So how exactly do you grow cultivated Morinda officinalis? Let's take a look below at how Morinda officinalis is grown.
1. Land Preparation
Morinda officinalis prefers a warm, humid environment. The soil of the planting site is generally best if it is relatively loose, fertile, well-drained, with moderate or slightly acidic pH, good permeability, and is red loam or yellow loam. At the same time, the planting site must have an ample water source, and is best located on flat ground or on terrain with a gentle slope. The preparation of the planting site generally needs to begin several months before sowing; before raising seedlings, break up and level the soil clods and prepare the beds. Finally, get the application of base fertilizer right, and simply apply enough base fertilizer.
2. Propagation Methods
The main methods of propagating Morinda officinalis are seed seedling raising and cutting seedling raising. Seed seedling raising is generally done by drilling, with a distance of about 15 cm between each row. The furrow is about 10 cm wide and about 5 cm deep, then the seeds are evenly scattered into the furrow and covered with soil. Cutting seedling raising, on the other hand, requires selecting relatively thick vine roots, each about 10 to 15 cm long, and then inserting them at a spacing of about 5 cm per plant.
3. Seedling Stage Management
The most important task in seedling stage management is shading. If growing from seed, the shade shed should be built after the seedlings emerge, but when using cutting propagation, the shade shed must be built immediately after planting. Then, after the seedlings have grown for three months, gradually reduce the degree of shading. At the same time, note that a rain shelter should be built to protect against rain and cold. We need to maintain the air humidity at around 60 percent, and when the seedlings have grown to about 15 cm, apply an appropriate amount of nitrogen fertilizer to promote seedling growth.
4. Cultivation Management
Morinda officinalis can only be transplanted once the seedlings have grown to about 30 cm, which means the seedling raising period is roughly ten months to one year. Within one month after transplanting, check the survival and growth of the seedlings in the field, replant missing seedlings promptly, and water reasonably to improve the transplanting survival rate. To reduce damage from pests and diseases, we should carry out intertillage and weeding multiple times. If the growth is poor, apply additional fertilizer promptly; plant ash, farmyard manure, or livestock manure can be used together with chemical fertilizer. During the flowering period of Morinda officinalis, remove the inflorescences promptly to promote root growth.
5. Pest and Disease Control
There are many diseases that harm the growth of Morinda officinalis, the most important of which are stem base rot, violet root rot, and sooty mold, with stem base rot being the most harmful. We can use sulfur powder, ammonium sulfate, and Baume-degree lime sulfur mixture for control. The most common pests include white grubs, scale insects, whiteflies, aphids, red spider mites, and root-knot nematode disease; we can use trichlorfon and dimethoate emulsifiable concentrate for spraying and killing.
The above are the methods for cultivating Morinda officinalis. I believe that by reading through the text above, you now have a general understanding, especially those friends who plan to grow Morinda officinalis: before planting, you need professional cultivation skills and an understanding of the growth habits of Morinda officinalis.
