What other management measures are there for macadamia orchards
1. Beekeeping in the orchard. Macadamia is an insect-pollinated flower; the main pollinating insects are honeybees, ground wasps, flies, thrips, etc. Keeping honeybees in the orchard greatly increases the chances of pollination between plants and between cultivars, which is of great benefit to raising yields. 2. Frost protection

2. Frost protection
Macadamia has fairly stable cold resistance. In normal years, in Guangxi, Guangdong, Xishuangbanna in Yunnan and most other areas, macadamia does not suffer frost damage, and it is enough to whitewash the trunks in winter as part of disease and pest control. In the Panxi region of Sichuan, the winter low temperatures last a long time (30~50 days), and especially the nighttime temperature drops greatly (a day-night temperature difference of about 10°C), so macadamia is prone to frost damage. In winter, in addition to whitewashing the branches and trunks, the main trunk should also be wrapped with plastic film and cold-protection materials.
3. Sun protection
When the temperature is ≥30°C, some macadamia cultivars such as 344# and 856# develop yellowing on the leaves of new shoots that have not yet matured, and in severe cases they dry up; after the hot season passes, the newly flushed shoots (leaves) return to normal, and plant growth is not greatly affected. This is more obvious during the young tree stage (1~4 years), and as the tree age increases this phenomenon weakens or may not even occur. In low-altitude (about 600 m) dry-hot areas such as Jinghong in Yunnan, during the hot, dry season (March to April), nighttime temperatures are relatively low, and in the morning the intense sunlight causes large temperature fluctuations, so the bark of macadamia stems and trunks splits open. In such areas, during the hot, dry season, stems and trunks should be wrapped with materials such as weeds to prevent sunscald; for stems and trunks that have already been split by sunscald, lime slurry or other coatings mixed with 0.05%~0.1% of 45% thiophanate-methyl or other fungicides should be applied to the trunks to prevent or reduce infection of the wounds.
