What do Hawaiian fruit trees look like? How many years after planting can it blossom and bear fruit?
Macadamia nut is macadamia nut. Among many dried fruits in the world, macadamia nut has high economic value and has always enjoyed the reputation of king of dried fruits. So what do Hawaiian fruit trees look like? How many years after planting can it blossom and bear fruit? According to Master Lu, a Hawaiian fruit grower in Xishuangbanna, Hawaiian fruit is cultivated in Yunnan, Guangdong and Taiwan Province in China, mostly in botanical gardens or farms. Generally, the grafted Hawaiian fruit trees blossom and bear fruit after 4 to 5 years, and enter the full fruit period from 10 to 12 years, with an economic life of more than 60 years.

Master Lu also revealed that Hawaiian fruit trees are suitable for planting in hills or flat land below1200m above sea level. The highest temperature in summer is generally not higher than 35℃, the highest temperature in winter is not lower than 15℃, and the lowest temperature is not lower than 0℃. There is no frost or occasional light frost all year round, and the soil layer is deep, rich in organic matter, with a PH value of 5.0 to 6.0, good drainage and irrigation in dry season. Because the tree has a dense crown and shallow roots, it is not wind-resistant, so the orchard should be built in places where there are few local strong winds all the year round and areas susceptible to typhoons, and bamboo and branches should be used as support during the young tree period to prevent wind damage.

Macadamia nuts are rich in nutrition, with an oil content of 70%-79%, especially characterized by rich in unsaturated fatty acids, mainly oleic acid and palmitic acid. The ratio of unsaturated fatty acids to saturated fatty acids in the kernel of macadamia nut with light shell is 6.2, and that of macadamia nut with coarse shell is 4.8. Protein accounts for 9%, and is also rich in calcium, phosphorus, iron, vitamin B 1, B2 and 8 kinds of amino acids necessary for human body. Macadamia nut has a bright market prospect and good ecological and economic benefits. It is an edible nut with high oil content, rich nutrition and unique flavor.

The global market demand for macadamia nuts is more than 400,000 tons. However, due to its strong selectivity to natural conditions such as light, heat, water and wind, and its long investment cycle, the global planting area is only 40,000 hectares, and the planting areas are mainly in Hawaii and Australia, with an annual output of less than 30,000 tons. Therefore, the development of Hawaiian fruit trees has great market potential and broad market prospects.
