The origin of cashew nuts, the main producing area of cashew nuts

Do you know the cashew nuts? Cashew nuts are something that everyone likes to eat. Is it known about the origin of cashew nuts? After all, like cashew nuts, which are often eaten, can be said to be familiar in our daily life. I can't be familiar with anything. Today I will introduce the origin of cashew nuts and the main producing areas of cashew nuts.


The origin of cashew nuts:

  Cashew nuts are native to northeastern Brazil.

  The main producing areas of cashew nuts:

    Cashew nuts were introduced to Asia and Africa in the 16th century and are now distributed in dozens of countries and regions within 20 degrees north and south. Mozambique, Tanzania, India, Brazil, Hainan and Yunnan have planted. Cashew trees were introduced to Asia in the sixteenth century. It was introduced to China about 50 years ago. ...[View Details]


Cashew growth habits, morphological characteristics of cashew nuts

Cashew, scientific name: (Anacardium occidentale) is a kidney-shaped nut, belonging to the genus Ranunculaceae. Also known as tree peanuts, such as trees, chicken cashews, Jieshou fruit. It has rich nutritional value, can be used for cooking, and can also be used for medicinal purposes. Today, we will introduce the growth habits of cashew nuts and the morphological characteristics of cashew nuts.


Cashew growth habits:

    An environment requiring high temperature and light. The average monthly temperature of 23-30 °C is normal, the growth is slow at 20 °C, lower than 17 °C, and vulnerable to cold damage. If it is lower than 15 °C, it will be seriously killed. The annual sunshine is more than 2000 hours, and the annual precipitation is 1000-1600mm. Neutral or slightly acidic soil with strong soil adaptability, deep soil layer and good drainage. Avoid flowering rain during the flowering period.

    Not resistant to low temperature, the average annual temperature is 24~28°C, and the monthly average temperature is 23~30°C. Hi light, suitable for annual sunshine hours is 1500~2000 hours. The annual drop of 1000~1600mm is appropriate. Neutral and even slightly acidic soils are suitable, but root growth prefers well-ventilated soil, poorly drained low-lying land, moor, alkaline soil and soil with too high salt content are not suitable for planting, and other types of tropical soil can be planted.

    It blooms 2 years after planting, and results in 3 years. After 8 years, it enters the fruiting period, and the fruiting period is 15-25 years.


How to raise cashew nuts, seedling technology of cashew nuts

Certain vitamins and trace elements in cashews have a good function of softening blood vessels, which is beneficial for protecting blood vessels and preventing cardiovascular diseases. It is rich in oils and can be used for laxative, moisturizing and anti-aging. Regular consumption of cashew nuts can improve the body's ability to resist disease and increase sexual desire. Today, we will introduce how to raise cashew nuts and raise cashew nuts.


Cashew seedling technology:

1. Real seedling

Convenient and easy to operate, such as live in Daejeon, without transplanting roots, the main root is strong, more resistant to drought and wind. Choose a good mother tree to collect fully mature nuts to sow, or 2-4d (to about 7% water content) for storage, storage time is less than 5 months, but if you can keep dry, the germination power can be kept for one year. the above. Nuts that are more important than others are germinated faster, the germination rate is higher, and the seedlings are stronger. It is better to use nuts with a size greater than l, a shiny skin, and a medium size. The seeds were soaked in clear water for 24 hours, and the germination rate was high and consistent. The sowing time is appropriate at the beginning of the rainy season (Hainan Island is from May to July), not later than September. The germination of nuts is related to temperature. It does not germinate at 10 °C, germination is rapid at 25-34 °C (average about 1Od), and the germination rate is high, but at 40 °C, the germination rate drops sharply. The time required for germination in different seasons is different. Seeding in May, l0-12d germination is basically over; in January, it takes more than 30 days. The sowing depth is generally 2-6cm, and the sand retains poor water, so it should be properly spread. The sowing method is to use the sowing (fruit stalk up) as well, and the hair is early and the seedlings are neat. Seedlings that were reversed (fruit-down) or ascended (fruit-up) did not grow well.

How to manage cashew nuts, management technology of cashew nuts

Cashew nut is a nutritious and delicious food, containing 48% fat, 21% protein, 10-20% starch, 7% sugar, and a small amount of minerals and vitamin A, vitamin B1, vitamin B2, used for making cashew chocolate, snacks. And fried salted foods, today we will introduce how to manage cashew nuts and the management technology of cashew nuts.


Cashew management technology:

 Soil management

 1. Fertilization The Institute of Tropical Agricultural Sciences studied a 9-year-old tree with a height of 4.7 m, with a green leaf of 68.2 kg, with an average of 31 inflorescences per square meter of canopy cover. Nutrient analysis of various organs showed that the nitrogen content of leaves, flowers and fruits was much higher than that of stems, branches and roots, and the kernel contained nitrogen, reaching 3.47%, the inflorescence content was 1.52%, and the main root was only 0.25%. The content is also high in nuts, reaching 0.449%, the main root is 0. 0183%. Potassium is the content of pear, calcium is the leaf content, and magnesium is inflorescence and nut content. According to the nutrient content of each organ, the nitrogen intake of a 9-year-old cashew tree is equivalent to 2.39 kg of ammonium sulfate. The test also showed that the phosphorus and potassium fertilizer had a good effect on the basis of nitrogen application. The amount of fertilizer applied increased with the increase of the age and the yield of the tree. In the year of planting, in addition to the application of the base fertilizer, there was generally no need to apply top dressing. In the second year, the urea was applied in each plant 0. 2-0. 3kg, and increased year by year. Potash.

How to fertilize cashew trees How to fertilize cashew trees

   Cashew nuts are also known as trees, chicken cashews, and Jieshou fruit. The nutritional value of cashew nuts is relatively high, rich in vitamin A, which can make the skin shiny and good in color; cashew nuts contain a large number of protease inhibitors, which can control cancer conditions. The cashew nut is highly adaptable. It is a thermophilic and strong positive tree species. It has low soil requirements. In addition to poor development on heavy clay and limestone, it can grow in red soil, sandy soil or rocky mountain with less than 1% soil organic matter content. . However, cashew planting also requires fertilization. The following small series is for everyone to share the fertilization method of cashew trees.


Cashew growth habit

Cashew nuts are not cold-tolerant and require high temperatures during the growth period. The average monthly temperature of 23-30 °C is normal, the growth is slow at 20 °C, lower than 17 °C, and vulnerable to cold damage. If it is lower than 15 °C, it will be seriously killed. The annual sunshine is more than 2000 hours, and the annual precipitation is preferably 1000-1600 mm. It is not advisable to plant in areas where the groundwater level is too high or where water is accumulated during the rainy season.


Fertilization method for cashew trees

Although the cashew tree is resistant to stagnation and drought resistance, the cultivation practice has proved that there is almost no yield of cashew trees that are naturally grown in love. After the fertilization of mature fruit trees, the yield will increase exponentially. From the perspective of fertilization types, N, P, and K were mixed to increase the yield; 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.
