1. Basic introduction to the Huangshan goldenrain tree

The Huangshan goldenrain tree is a tree that can reach a height of over 20 m, widely distributed in China in Guangdong, Guangxi, Jiangxi, Hunan, Hubei and other places, on hilly land at an altitude of 100-300 m, beside villages, or in open mountain forests at 600-900 m.

The Huangshan goldenrain tree prefers deep soil layers and a slightly acidic environment, so in summer the branches and trunk are easily scorched by the fierce sun, causing the bark to split and decay, resulting in serious damage. For newly planted entire-leaf goldenrain trees, after transplanting, whitewashing can be done, and straw rope can also be used to wrap the trunk for about 2 m to reduce water evaporation.

2. Is the Huangshan goldenrain tree a deciduous tree or an evergreen tree?

The Huangshan goldenrain tree is a deciduous tree, with the Chinese scientific name entire-leaf goldenrain tree. It is a tree in the genus Koelreuteria in the family Sapindaceae, mainly distributed in China in Guangdong, Guangxi, Jiangxi, Hunan, Hubei, Jiangsu and other regions.

3. Pest and disease control of the Huangshan goldenrain tree

1. Goldenrain tree aphids: begin spraying at the early nymph stage with a 2000-fold dilution of Yashijing or other imidacloprid-type insecticides, or at the early stage of infestation promptly prune off the heavily infested sprouting branches on the trunk to eliminate the newly appearing aphids that have not yet spread.

2. Red-necked longhorn beetle: trunk injection with chemicals is quite effective for controlling the red-necked longhorn beetle; systemic insecticides can be used.

3. Goldenrain tree gummosis: scrape the scar and apply medicine. Use a blade to scrape off the gummy substance on the branches and trunk, then apply a 10-fold combing agent to the wound.

4. Japanese wax scale: during the major outbreak period of nymphs, spray a mixed solution of 2000-fold Lorsban and 1000-fold washing powder, spraying 2 to 3 times at intervals of 7 to 10 days. Using 25% carbofuran wettable powder at 200- to 300-fold for root irrigation twice in May has a very good effect on killing nymphs.
