Abstract:: Taking chestnut soil，sands，peat moss etc as experimental materials，according to different proportion to assemble six cultures substrates，the effects of different culture substrates on root growth and nutrient absorption of Tulipa gesneriana L were studied.The results showed that plant in chestnut soil∶sands∶peat moss=5∶3∶2，root growth was the best，root number and length all reached remarkable difference.And in six different culture substrates had different absorption rate of nutrient.Available N,P,K absorption rate in chestnut soil∶sands∶peat moss=5∶3∶2 were the best,chestnut soil∶peat moss=1∶1 and chestnut soil∶sands =1∶1 also had better absorption rate of available N，P，K，but in the sands,the absorption rate were the worst.
