The invention discloses an intermediate-cutting and tending method of a clustered bamboo forest used for large and medium profiles. The method includes the following steps that afforestation is conducted by using standard clusters, and a crown area with the radius R1=2.5m and a stump area with the radius R2=1m are set up for each standard clump, wherein the crown area is concentric with the stumparea; Each standard cluster is divided into four quadrants, and intermediate cutting of bamboo plants is conducted on each standard cluster in the annual dormancy period through a 1/1.4 quadrant intermediate cutting means; every time, after intermediate cutting of bamboo plants, the structure of the bamboo forest is adjusted by a 1/2 quadrant bamboo-shoot retaining and removing means in the shooting period at the same year; 360-degree circular fertilization pits with the width of 30 cm and the depth of 30 cm are excavated 50 cm away from the stump area, and fertilization is conducted twice a year; new bamboo shoots in the current year are subjected to topping at the same time after the height growth stops. The method can effectively improve the cutting efficiency of clumped bamboo forests,labor is saved, the management cost of the clustered bamboo forest is thus reduced, at the same time, the yield of bamboo wood is increased, and the method is suitable for intensive management of theclustered bamboo forest used for large and medium profiles in southern China.
