A Detailed Guide to Noni Cultivation Methods, Master the Latest Cultivation Techniques

Noni is a rather uncommon fruit, the fruit of the morinda tree; it has excellent strengthening effects and can also boost the human immune system, and furthermore it can help with detoxifying and beautifying, delaying menopause, and preventing cancer, making it a very good health fruit. It is mainly produced in 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. Next, site selection should be divided into nursery land and planting land. For noni nursery land, factors such as wind, sunlight, water source and soil quality are generally considered, while for the planting land the main considerations are soil fertility, water source, soil quality and transportation, so it needs to be chosen according to the growth habits of noni. Finally, land preparation must ensure the soil is finely and evenly tilled.

2. Planting Methods

There are mainly two methods of planting noni: raising seedlings from seed and transplanting, and raising seedlings from cuttings and transplanting. Sowing seeds is generally best done around April to June each year, and 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, soak them in warm water for another day, and finally disinfect and sterilize them with Bordeaux mixture. This can increase the seed germination rate and also enhance the resistance of the seeds. Cutting propagation is generally carried out around March to April each year; cut a notch in the selected noni branch, place it in Bordeaux mixture to disinfect, then insert it into the soil to raise the seedling.

3. Reasonable Close Planting

Transplanting and field planting are generally carried out from June to July each year. The planting density is usually about 1 m between rows and about 60 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 and what 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 will also do. When noni flowers 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 of the coming year. At the same time, each fertilization can be combined with intertillage 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. Branch and Leaf Pruning

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