How to Grow Cashews? The Latest Cashew Planting Techniques and Methods Tutorial
The cashew is one of the four major dried nuts in the world. It originally came from the Americas and was then gradually introduced to Asia. It now has a wide planting area in our country, with the main growing regions concentrated in tropical provinces such as Hainan and Guangdong. The market price of cashews is relatively high, offering considerable profit potential for growers. So how should cashews be planted? Below, the editor brings you the cashew planting techniques. Let's take a look!
1. Environmental Selection
The cashew has relatively strong adaptability. It was originally a tropical fruit, so it likes to grow in environments with high temperatures and strong light. The cashew's cold tolerance is very poor. When the temperature is below 20 degrees, its growth will be restricted, and when it is below about 15 degrees, it is prone to frost damage. Although the cashew has strong adaptability to soil and can grow normally in most soils, in order to improve the yield and quality of cashews, we should try to choose fertile, loose soil rich in humus and with strong permeability, which can further improve the growth capacity of cashews.
2. Shaping and Pruning
There are several propagation methods for cashews, mainly graft propagation. After successful propagation, we should strengthen management to promote the growth of young trees. And during the growth of cashew trees, shaping and pruning work should be done well. Shaping and pruning can improve the overall structure of the cashew tree, increase its permeability, and boost yield. However, when pruning young cashew trees, we should pay attention to the intensity and not overdo it; pruning should be as light as possible. The pruning frequency can be appropriately increased. While improving the tree structure, we must avoid causing damage to the cashew tree, which would lead to the opposite effect.
3. Reasonable Fertilization
⟦NL>Although cashew trees have strong tolerance to poor soil, it still has a certain impact on their yield and fruit quality. Professional data surveys have shown that wild cashew trees produce very little or even no fruit when lacking nutrients. Therefore, when planting, we need to do a good job of fertilization, especially after the trees reach maturity, when the amount of fertilizer should be increased again. Fertilization should mainly use nitrogen, phosphorus, and potassium fertilizers. The ratio of nutrient elements will affect the flowering period of cashew trees. A high proportion of nitrogen will delay the flowering period; on the contrary, a high proportion of phosphorus and potassium fertilizer will shorten the flowering period. The annual fertilization nutrient ratio should be controlled at about 3:1:1 for nitrogen, phosphorus, and potassium, which can effectively improve yield and kernel outturn rate.
4. Pest and Disease Control
Throughout the entire growth period, cashews will be threatened by many pests and diseases, and the types of pests and diseases differ at different growth stages. Common pests and diseases include phytophthora blight, damping-off, mirid bugs, scarab beetles, and so on. These pests and diseases will harm different parts of the cashew tree to varying degrees, causing flower and fruit drop, rotten fruit, and other yield-reducing phenomena. We should take corresponding preventive measures according to the pests and diseases at different growth stages to strengthen the disease resistance of cashew trees. When pests and diseases are found, we should promptly check exactly what pests and diseases they are, and then apply the appropriate treatment.
The above is a brief introduction to cashew planting techniques. The early planting period of cashews is relatively long, so everyone should ensure sufficient funds in the first few years when planting. And you must also ensure a suitable planting environment; otherwise, the editor does not recommend planting. That is all for today's introduction.
