Tetraploid Robinia pseudoacacia
Tetraploid Robinia pseudoacacia is one of the excellent clones of polyploid Robinia pseudoacacia introduced from abroad, which has been selected by painstaking research and experiment for many years. Tetraploid Robinia pseudoacacia is an artificially induced tetraploid plant with fast growth, large leaves and large biomass. Its leaf width is more than 2 times that of common Robinia pseudoacacia. Compound leaf dry weight, single leaf dry weight and total leaf dry weight are 1.5 times or more than that of common Robinia pseudoacacia. Compared with common Robinia pseudoacacia, tetraploid Robinia pseudoacacia has thicker crown, stronger branches and stronger photosynthetic capacity. The content of crude protein and crude fat of tetraploid Robinia pseudoacacia is very high, which is 118% and 126% of that of common Robinia pseudoacacia, respectively, which is very suitable for animal feed, and tetraploid Robinia pseudoacacia is very resistant to cutting and flat stubble, and can be used repeatedly with certain management techniques. Tetraploid Robinia pseudoacacia is resistant to barren, and its roots can fix nitrogen, so it can be used as a pioneer tree species for greening barren hills and barren slopes, as well as excellent tree species for soil and water conservation in river basins and greening on four sides. After the variety was introduced into China, through multi-point experimental observation in different areas, all the indexes have reached or exceeded the expected level. At present, the Chinese Academy of Forestry Sciences has organized experts to conduct repeated and continuous studies in several experimental bases in North China, and have explored a set of scientific cultivation and reproduction methods suitable for large-scale planting. At the same time, a large number of high-quality seedlings have been rapidly bred by cutting, grafting and tissue culture, which can provide high-quality pure seedlings to the society, as well as related breeding, cultivation and management techniques.

Robinia pseudoacacia
Call it a tree, it blossoms every year, call it a flower, look like a tree no matter how it looks. This is called Robinia pseudoacacia, also known as rich tree, is a precious tall tree species successfully introduced from abroad. Every year in May, when the spring is getting stronger, Robinia pseudoacacia will bloom beautiful flowers. Unlike other trees, Robinia pseudoacacia can blossom twice a year, each time for up to a month, so it is a good tree species for greening. You don't believe me? First look at the shape of the tree, the crown is open, the trunk is straight, and it is full of woody plants; then look at the leaves, which are not long or short, smooth and beautiful; the flowers are

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
