The monocrystal growing furnace in multiple falling crucible method includes one furnace body and one elevating platform, the furnace body has hearth, and the elevating platform has 1-15 crucible muffs with 1-2 crucible each set along the hearth. The hearth includes one high temperature region, one growth region and one low temperature region, and features the low temperature region of width 2 times that of the high temperature region and the hearth width regulator set in the low temperature region. The present invention is superior in that regulating the hearth width ratio between the high temperature region and the low temperature region can regulate the temperature gradient in the growth region to meet the requirement of growing different kinds of crystal on the temperature field and that 1-30 different monocrystals may be grown simultaneously in the furnace.
