The latest course on planting techniques and methods of cashew nuts

Cashew is one of the four dried nuts in the world, originally from America, and then gradually introduced into subspecies. Now it has a wide range of planting areas in China, and the main planting areas are concentrated in Hainan, Guangdong and other tropical provinces. The market price of cashew is relatively high and there is considerable profit space for planting. So how to grow cashew nuts? The following editor brings you the planting technology of cashew nuts, let's have a look!

1. Environmental selection

Cashew is relatively adaptable, originally a tropical fruit, so it likes to grow in high temperature and strong light environment. The cold resistance of cashew is very poor, when the temperature is lower than 20 degrees, its growth will be limited, when it is less than 15 degrees, it is easy to produce frost damage. Although cashew nuts have strong adaptability to soil, they can grow normally in most soils. However, in order to improve the yield and quality of cashew nuts, we should try to choose rich and soft soil with rich humus and strong permeability, which can further improve the growth ability of cashew nuts.

2. Shaping and pruning

There are several propagation methods of cashew nuts, mainly by grafting. After successful reproduction, we should strengthen management to promote the growth of young trees. And in the cashew tree growth to do a good job of shaping and pruning, shaping and pruning can improve the overall structure of cashew trees, improve the permeability of cashew trees and increase yield. However, when we trim young cashew trees, we should pay attention to the strength, not to overdo it, and trim it as lightly as possible. Pruning frequency can be increased appropriately, while improving the tree structure, it is necessary to avoid damage to cashew trees, which is counterproductive.

3. Rational fertilization

Although cashew tree has strong resistance to barren, it still has a certain effect on its yield and fruit quality. There has been a professional data survey shows that the yield of wild cashew trees is very low or even fruitless in the case of lack of nutrition. Therefore, we need to do a good job of fertilization when planting, especially when the fruit is grown up. Nitrogen, phosphorus and potassium fertilizer is the main fertilizer during fertilization, and the proportion of nutrient elements will affect the flowering period of cashew trees. The high proportion of nitrogen will delay the flowering stage, on the contrary, the high phosphorus and potassium fertilizer will shorten the flowering period. The annual fertilization nutrition ratio should be controlled at about 3:1:1 of nitrogen, phosphorus and potassium, which can effectively increase the yield and kernel yield.

4. Pest control

Cashew nuts are threatened by many diseases and insect pests during the whole growth period, and the types of diseases and insect pests are different in different growth stages. Common diseases and insect pests are blight, sudden collapse, blind bugs, beetles and so on. These diseases and insect pests will harm different parts of cashew trees in varying degrees, resulting in reduced yield, such as falling flowers and fruit, rotten fruit and so on. We should take corresponding preventive measures according to the diseases and insect pests at different growth stages to strengthen the disease resistance of cashew trees. When discovering the situation of diseases and insect pests, we should check in time what the specific diseases and insect pests are, and then prescribe the right medicine to the case.

The above is a brief introduction of cashew planting technology, the early planting time of cashew is relatively long, so we should ensure that there are sufficient funds in the first few years. And also to ensure that there is a suitable planting environment, otherwise the editor does not recommend that everyone plant. That's all for today's introduction. This article is for reference only. I hope it can help you all.
