What are the key points to note when growing rambutan? The latest essentials explained in one article
The taste of rambutan is extremely similar to that of lychee, so it is also called hairy lychee. Rambutan has a rather beautiful appearance and can be used as an ornamental garden tree. It is a tropical fruit with great economic value, and its position in the market is no less than that of lychee, although currently it is only grown on a large scale in Hainan, Guangdong and other regions. However, rambutan has high economic value and relatively excellent quality, so it is a fruit with great development prospects. Below, let us explain the points to note when growing rambutan!
1. Climate
Rambutan cultivation is generally limited by temperature, because rambutan itself is a tropical fruit. It is suitable for growing in relatively high-temperature environments. Slightly lower temperatures will affect the normal growth of rambutan, and the average temperature is best around 25 degrees. Rambutan also likes humid environments, and it will not suffer wind damage. Rambutan seedlings are extremely intolerant of drought, so water should be appropriately increased for them at the seedling stage. Water is most needed during the fruit-bearing period, and the annual precipitation at the planting site should be at least 1800mm.
2. Washing the seeds
After selecting the variety, the seeds should be washed and soaked once, for the purpose of disinfecting the seeds. Rub and wash the sugar off the seeds in clean water. If there is pulp, it must also be rubbed off, ensuring that no sugar or pulp remains on the seeds, because if they are not washed clean, the aroma will affect ants or other pests, thus easily arousing their interest, and they will gradually be attracted to gnaw on them, having a relatively large impact on the seeds and young sprouts.
3. Weeding
When the first seedling leaf appears, weed around it in time, and loosen the soil between each plant. However, note that when weeding, you must not be too rough or too forceful, to prevent damaging the underground roots. Apply a light water-soluble fertilizer once a month. The fertilizer should contain a compound fertilizer of nitrogen, phosphorus and potassium, and should not be excessive. Determine the fertilization amount according to the quantity. This compound fertilizer helps rambutan absorb nutrients in a balanced way.
4. Pests
Rambutan pests mainly occur during the seedling stage of rambutan. Tussock moths harm its leaves. If the number of pests is not great, it is best to use manual capture and killing. If it has already become a disaster, then emamectin benzoate should be used as an insecticide. This pesticide has strong killing power, and an obvious effect can be seen after one spray. After spraying, because emamectin benzoate has strong penetrating ability, it can quickly excite and paralyze the pests, causing them to die rapidly, and it has no effect on humans or livestock.
5. Environment
The rambutan garden must have a good irrigation and drainage system. Areas with poor drainage are not suitable for cultivation. Rambutan is also a fruit that greatly likes light. To achieve good growth, flowering and fruiting of rambutan, there must be sufficient light duration. Although rambutan will not suffer wind damage, strong winds can easily blow off the branches and leaves of the plant, causing rambutan to lose leaves and branches, and having an adverse effect on the growth and development of rambutan. Fertile soil, deep soil layers and sandy soil that remains moist often will help the plant grow.
The above are the points to note when growing rambutan. Everyone must pay special attention to pests. Not only are there pest threats, but diseases also cause serious harm to rambutan cultivation. Pay attention to the sanitation and cleanliness in the garden. After harvesting the fruit each winter, disinfect the orchard promptly and comprehensively, clean up diseased and disabled branches, reduce sources of disease, and lower the disease incidence in the coming year.
