Modern people like to eat a variety of small snacks, such as cashews. Cashew nuts are introduced from China to the Americas. Cashew nuts are grown in many areas of China. Currently, cashew nuts are grown mainly in some provinces in the south. Nowadays, the demand for cashew nuts is still relatively large and the price is very high. Therefore, many people want to join the cashew planting industry. In the middle, how to plant cashew nuts? Let's take a look at the following. 1. Cashew planting environment Cashew nut growth ability is very strong, can adapt to many environments, as a tropical fruit, it has higher adaptation to light and temperature, but cold tolerance is poor, once the temperature is lower than 20 degrees, growth will be hindered, low At 15 degrees, various problems are easy to occur, and this should be noted. In addition, most of the soil can make it survive, so in order to improve the efficiency of cashew planting, it is best to choose those soil plants that meet high standards. 2, cashew propagation method There are many methods for the reproduction of cashew nuts, most of which are grafted and propagated. However, in order to ensure the good growth of young saplings, we must manage them. When growing, we need to trim the whole tree to achieve high yield, but pay attention to the pruning. Strength, once too much over-trimmed wounds can not recover in time, it will cause a lot of damage, production and quality will also be affected. 3. Fertilization management of cashew nuts Although the cashew tree is resistant to stagnation and drought resistance, cultivation practice has shown that there is almost no yield of cashew trees grown in the natural state. After the fertilization of mature fruit trees, the yield will increase exponentially. From the perspective of fertilization types, N, P, and K mixed application had the best effect; secondly, P was applied again, and N and P were mixed again. Higher levels of N can prolong flowering, while higher levels of P and K shorten flowering. Each year, N600 grams, P200 grams, and K200 grams per plant can significantly increase the individual planting of nut trees, increasing total yield and yield. 4, cashew disease and pest control Cashew nuts are endangered by more than 60 pests at different stages of their growth. Among them, cashew disease mainly includes inflorescence blight, stagnation disease, gum disease, branch rot disease, leaf rot, yellow leaf spot disease, lobular disease, etc.; the main pests are cashew horned owl, cashew moth, cashew mites, Chafers and so on. (1) Cashew nut mites are a kind of cashew tree stem pests, and its control is best carried out during the spawning period from July to August. Generally, 0.15% of carbaryl or 0.05% of monocrotophos can be used to treat cashew trees. Bare roots. (2) The larvae of the scarab mainly harm the roots of cashew nuts. The method of chemical control is to apply the best ingredient of 1 kilogram of stone sulphur mixture per hectare, and the insect worms decrease by 74.4% after 15 days of treatment. The above is about the introduction of cashew nuts. In order to achieve high yield and high quality of cashew nuts, in addition to meeting the growing environment, the management of the later stage is also very important.
