Detailed Explanation of the Latest Precautions for Areca Nut Cultivation

Areca nut is a very common food in our lives, and it is a pastime that many young people use to kill time when they are bored, gradually showing a trend of replacing cigarettes. Areca nut cultivation is actually not very easy, and it often encounters all kinds of problems. Today Qinnong Web brings you some issues to pay attention to when cultivating areca nut, hoping to help everyone.

1. Planting Conditions

Areca nut generally comes from regions with a tropical rainforest climate, such as Southeast Asia, while in China areca nut mostly comes from the Hainan region, which is mainly related to the climate and environment. The temperature suitable for areca nut growth is best when it remains high throughout all four seasons, preferably controlled at around 15 to 35 degrees, while high humidity must also be maintained. Planting is generally done on plots with a certain slope, and sufficient base fertilizer needs to be applied to ensure the most basic growth needs of the areca nut trees.

2. Planting Methods

There are quite a few things to pay attention to in planting methods. First, the seeds need to be germinated before sowing. There are two methods of germination: one is soaking the seeds, and the other is piling. First, soaking the seeds means placing the seeds in water to soak for about ten days, then soaking them in medicinal solution, and finally placing them under conditions that meet germination requirements for germination. Piling, on the other hand, means putting the seeds into a soil pile, then watering them thoroughly, and covering them with straw and film to germinate. When most of them have grown white sprouts, they can be raised as seedlings. When raising seedlings, it is best to use nutrient solution, as the seedling emergence rate will be much higher than with the ordinary direct seedling-raising method. Nutrient solution seedling raising means placing seeds that have already produced white sprouts on a seedling bed, then delivering nutrient solution to the seedling bed. In the early stage there will be more nutrient solution, and then it gradually decreases, so that they adapt to the environment they will grow in later.

3. Planting Density

Planting density is also a condition that requires great attention in areca nut cultivation. Although areca nut does not grow especially tall, it is still a tree, and it also needs a large amount of light. If planted densely, the areca nuts it can produce will be fewer, so the best planting density is a spacing of 2 to 3 m between each plant and 3 m to 3.5 m between each row.

4. Fertilization Techniques

The growth of areca nut requires a large amount of nutrients, so fertilization needs to be carried out multiple times, and each fertilization must be sufficient. Nitrogen fertilizer is the main type, followed by phosphorus fertilizer and potassium fertilizer during the flowering and fruiting stage. Before each fertilization, intertillage and weeding need to be carried out first, removing weeds in the field to reduce unnecessary nutrient consumption. Before the areca nut has grown into a large tree, some farmyard manure also needs to be applied each year to maintain nutrient balance. Finally, during the flowering and fruiting stage, the nutrients it consumes will be relatively high, and this is also the time in its entire growth period when it consumes the most nutrients, so the nutrients need to be replenished sufficiently, generally reaching 70 percent of the growth period. Finally, when it enters the dormant period, maintenance is also needed.

5. Pest and Disease Control

Common diseases of areca nut include root rot and leaf rot. Although both diseases cause rotting of areca nut to varying degrees, the treatment methods are completely different. The control method for root rot is to spread some lime on the roots or use chlorothalonil for disinfection, while leaf rot requires irrigation with a 500-fold dilution of copper hydroxide (basic copper sulfate) suspension concentrate. Finally, we also need to pay special attention to the areca nut black whitefly, which causes especially serious damage to areca nut, so we often need to spray imidacloprid solution for prevention.
