What are the precautions for coconut cultivation? A detailed explanation of the latest cultivation key points
Coconut is a very popular tropical fruit, mainly produced in the Hainan region of China. Its use value is relatively wide-ranging, and there are many foods on the market that use coconut as a raw material, especially coconut water and coconut meat, which are foods loved by young and old alike and are deeply loved by everyone in the market. Their sales volume and economic value are very considerable, so more and more friends are growing coconuts. So today, the editor will introduce to you the precautions for growing coconuts. Let's learn together.
1. Time
The time for coconut planting is mainly closely related to the local climate conditions. In general, the temperature in the Hainan region is relatively mild throughout the year, so we choose the expected time for planting, that is, around April and May. At this time, the rainfall is also relatively high, and the temperature at this time has basically reached the standard required for planting coconuts, so we must find the right planting time. At the same time, in some places it can also be planted around September and October, and the conditions at this time are also very good.
2. Temperature
The temperature suitable for coconut growth is generally around 25 to 28 degrees, of which the lowest growth temperature cannot be lower than 13 degrees, and the highest temperature cannot be higher than 38 degrees. If the temperature is lower than 13 degrees, the coconut tree will enter a dormant stage and thus will not flower or bear fruit. Although coconuts like a high-temperature and rainy environment, the temperature cannot be too high either, otherwise it will also damage the coconut water itself, thereby affecting the fruit yield of the coconut tree. Therefore, in our usual field management, we need to strictly monitor the temperature and carry out reasonable regulation.
3. Density
The density of coconut planting is mainly divided into two stages. The first is the seedling raising stage. At this time, the coconut trees are still relatively small, so in order to fully utilize land resources, sowing and seedling raising are generally carried out at a distance of 40 to 45 cm per row and 35 to 40 cm per plant. When the coconut seedlings grow to a certain size, they need to be transplanted. During transplanting, attention should be paid to bringing the original base soil, so that the survival rate will be higher. Then they are planted at a distance of 8 to 9 m per row and 6 to 7 m per plant. This density allows each coconut tree to carry out sufficient photosynthesis, thereby increasing coconut yield.
⟧4. Fertilizer and water
After the coconut trees have been planted for 7 to 10 days, check their survival condition, replant missing seedlings in time, and then provide appropriate shading from the sun to avoid damaging root growth. Watering should also be done reasonably. The growth of coconut trees requires a large amount of nutrients, among which potassium fertilizer is the main one, and nitrogen fertilizer and phosphorus fertilizer can be appropriately increased. If the stems of the coconut trees are found to be very thin and show symptoms of wilting, this is a sign of potassium fertilizer deficiency, so fertilizer should be applied in time. If the coconuts turn yellow, then chlorine fertilizer needs to be applied as a top dressing. Each fertilization is carried out by the method of trenching and ring application. Basically, fertilization only needs to be done twice a year, that is, around April and May in spring and around December in winter.
5. Pests and diseases
The prevention and control of coconut pests and diseases is a point that we need to pay special attention to. Among them, the main pests and diseases harming the growth of coconut trees are bleeding disease and red palm weevil larvae, scale insects, and coconut rhinoceros beetles. For bleeding disease, we need to dig out the affected parts, then apply a layer of Bordeaux mixture for disinfection and prevention. For insect pests, respectively, bitumen, ammonium sulfophosphate, and rotting coconut trunks can be used for trapping and killing.
