Detailed Explanation of Noni Cultivation Methods and Techniques

Noni is a rather uncommon fruit, the fruit of the morinda tree. It has excellent health-strengthening effects and can also enhance the human immune system. In addition, it can help with detoxification and beauty care, delay menopause, and prevent cancer, making it a very good health fruit. It mainly comes from Southeast Asia, Hawaii, and other places. So how is noni cultivated? Let's take a look together today.

1. Site Selection and Land Preparation

Before planting noni, we need to select a site. It is a tropical fruit, so the growing climate is basically tropical or subtropical. Secondly, site selection should be divided into seedling land and planting land. For noni seedling land, considerations generally include wind, sunlight, water sources, and soil quality. For the planting land, the main considerations are soil fertility, water sources, soil quality, and transportation. Therefore, selection needs to be based on the growth habits of noni. Finally, land preparation must ensure the soil is finely broken up and leveled.

2. Planting Methods

There are mainly two methods for planting noni: raising seedlings from seeds and transplanting, and raising seedlings from cuttings and transplanting. Seed sowing is generally best done around April to June each year. Before sowing, the seeds need to be soaked in warm water. After about a day, remove them, wrap the seeds in gauze, add an appropriate amount of fine river sand in the middle, and rub and wash them. After rubbing and washing them clean, put them in warm water to soak for another day. Finally, use Bordeaux mixture for disinfection and sterilization. This can increase the seed germination rate and also enhance the seeds' resistance. Cutting propagation is generally carried out around March to April each year. Cut a slit in the selected noni branch, place it in Bordeaux mixture for disinfection, and then insert it into the soil for propagation.

3. Reasonable Close Planting

Transplanting and field planting are generally carried out from June to July each year. The planting density is usually about one meter between rows and about sixty cm between plants. Only planting at this density can ensure the normal growth of noni. At the same time, when field planting, it is best to choose a rainy or cloudy day, as this can improve the survival rate of noni.

4. Fertilizer and Water Management

Noni grows very slowly during its seedling stage. So how should we fertilize it, and what kind of fertilizer is better? During the seedling stage, urea is generally used to promote the growth of branches and leaves, or a three-element compound fertilizer can also be used. When noni blooms and bears fruit, phosphorus fertilizer is mainly used, with as little nitrogen fertilizer as possible. After noni is harvested, some three-element compound fertilizer needs to be applied for maintenance, so that it can safely pass through winter and ensure the yield for the coming year. At the same time, each fertilization can be combined with cultivating and weeding and watering, so that the nutrients can be fully absorbed, thereby promoting the growth of the noni root system, branches and leaves, and fruit.

5. Pruning of Branches and Leaves

The last thing to pay attention to is the pruning of branches and leaves and the thinning of flowers and fruits of the noni tree. Noni generally blooms quite a lot, so we should appropriately thin out some weak flowers, diseased flowers, and so on. At the same time, branch and leaf pruning needs to be carried out once or twice each year. This can strengthen the tree and also increase the yield.
