Macadamia nut is a high-grade cash crop in tropical and subtropical regions with strong adaptability. Suitable for planting in hills or flat land below1.200m above sea level. It is required that 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. The soil layer is deep, rich in organic matter, with a PH of 5.0 to 6.0 and good drainage.

Extended data:

The temperature of macadamia nuts is relatively cold-resistant, and young trees can tolerate the low temperature of -4℃, and the frost period is days, which is intact; Adult trees can withstand a temporary low temperature of -6℃.

Young trees are mainly sparse branches or buds. When the main branch is larger than 30 cm, it is centrifuged or chopped for the first time to promote its branching. After the main branches are cut off, the above three axillary buds germinate and grow. When it grows to 3-4 nodes, only one branch will continue to grow into the main branch, and the other two branches will nucleate at 3 or 4 nodes. When the terminal bud of the main branch grows to about 30 cm at the last branching point, it is picked to promote its branching.

The management of macadamia nuts is extremely sensitive to water, and it can't be short of water from flowering to maturity, especially in the period of fruit oil accumulation, which will seriously reduce the quality and yield of nuts. When young leaves wilt and mature leaves lose their luster, it is a sign of water shortage, so irrigation should be done in time.
