Polyploid Robinia pseudoacacia, a new tree species suitable for growing in barren soil
A small sapling less than 10 cm long, only like a pea seedling, planted in barren land where nothing grows, can jump more than 3 meters high in a year. This is a new type of tree species suitable for planting in western China, which was successfully cultivated by experts from Changyi City, Shandong Province and Beijing Forestry University on the basis of introducing foreign tree species and adopting plant tissue culture technology. It has become a "golden sapling" with excellent drought resistance, saline-alkali resistance and barren resistance. Luyuan Center in Changyi City, Shandong Province has also developed into the largest scientific research and production base of "polyploid locust" in China.
Since July last year, under the guidance of Luo Xiaofang and Tian Yanting, professors of Beijing Forestry University, Luyuan Center of Changyi City has invested more than 2 million yuan successively to introduce new locust tree species from Hungary and South Korea. According to the needs of western development, advanced plant tissue culture technology has been used to select locust tree species with drought resistance, salt alkali resistance and barren thin soil resistance, and has been successful. Three series of polyploid locust varieties have been bred for forage, nectar and timber.
Now, under the careful guidance of experts from Beijing Forestry University and strong support from all sides, the center has rapidly developed into the largest research and production base of "polyploid locust" in China, and nearly 1 million polyploid locust seedlings have been transported to western provinces and cities.

Tetraploid Robinia pseudoacacia fine varieties
Tetraploid Robinia pseudoacacia was cultivated by Forest breeding Institute of Mountain Forest Department in Korea and introduced into China in 1997. There are five excellent clones of two types: feed type and material type. Through the expert regional cultivation experiment of our school, two excellent clones suitable for the construction of fine fodder forest and fast-growing and high-yield timber forest in arid and semi-arid areas of Northwest China were selected. these excellent clones not only maintain the original advantages of drought tolerance, barren tolerance and saline-alkali tolerance of Robinia pseudoacacia, but also have the following outstanding characteristics: (1
