Cashew planting technology

Cashew nuts are one of the four largest nuts in the world, originally grown in the Americas, and then gradually introduced subspecies. Now in China has a wide range of planting area, the main planting areas concentrated in Hainan, Guangdong and other tropical provinces. The market price of cashew nuts is relatively high, with considerable planting profit space. So how do cashews grow? The following small series brings you the planting technology of cashew nuts. Let's take a look together!

1. Environmental choice

Cashew nuts are more adaptable, originally a tropical fruit, so they like to grow in high temperature and strong light environment. Cashew cold tolerance is very poor, when the temperature is lower than 20 degrees when its growth will be limited, less than 15 degrees when it is easy to produce freezing damage. Although cashew nuts are adaptable to soil, they can grow normally in most soils. However, in order to improve the yield and quality of cashew nuts, we should try our best to choose fertile soft, humus-rich and permeable soil, which can further improve the growth ability of cashew nuts.

2. Shaping and pruning

There are several methods of cashew reproduction, mainly grafting propagation. We should strengthen management after successful reproduction to promote the growth of young trees. And in cashew tree growth to do a good job of pruning, pruning can improve the overall structure of cashew trees, improve the permeability of cashew trees, increase production. However, we should pay attention to the intensity of pruning young cashew trees, not excessive, and try to cut them lightly when pruning. The pruning frequency can be increased appropriately, and while improving the tree structure, it is necessary to avoid causing damage to cashew trees, resulting in counterproductive.

3. Reasonable fertilization

Although cashew tree has strong barren resistance ability, its yield and fruit quality are still affected to some extent. There have been professional surveys showing that wild cashew trees in the absence of nutrients in the case of its yield is very low or even no fruit. Therefore, we need to do a good job in fertilizing when planting, especially after the fruit is mature, the amount of fertilizer should be increased again. Nitrogen, phosphorus and potassium fertilizer were the main fertilizer, and the proportion of nutrient elements would affect the flowering of cashew trees. High N ratio delayed flowering, whereas high P and K ratio shortened flowering. The ratio of N, P and K should be controlled at 3:1:1 every year, which can effectively improve the yield and kernel rate.

4. Pest control

Cashew nuts are threatened by many diseases and pests throughout their growth period, and the types of diseases and pests vary according to their growth stages. Common diseases and insect pests are epidemic diseases, damping-off disease, bugs, scarabs and so on. These diseases and insect pests will harm different parts of cashew trees to varying degrees, resulting in flower drop, fruit rot and other production reduction phenomena. We should make corresponding preventive measures according to the diseases and insect pests in different growth stages to strengthen the disease resistance of cashew trees. When finding diseases and insect pests, we should check what diseases and insect pests are in time, and then carry out the right medicine.

The above is a brief introduction to cashew planting technology. The early planting time of cashew nuts is relatively long, so everyone should ensure sufficient funds in the first few years of planting. And also to ensure that there is a suitable planting environment, otherwise Xiaobian does not recommend everyone to plant. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
