BACKGROUND OF THE INVENTION 1. Field of the Invention: The present invention relates to bamboo baskets and more particularly, to the fabrication of modularized bamboo frame member set for bamboo baskets. 2. Description of the Related Art: Various materials including ceramics, glass, wood, plastics, stainless steel, and etc. may be used for making tables, chairs, cabinets, storage containers, and many other furniture. To show an antique sense of beauty, wood and bamboo are intensively used to make furniture and storage containers. A conventional bamboo furniture is known comprising a frame structure and a plurality of wall panels formed of bamboo strips by weaving. These bamboo panels have open spaces, and are fastened to the frame structure by an adhesive or by means of binding wires There is known another structure of bamboo furniture in which the bamboo panels are formed of transverse bamboo slats and longitudinal bamboo slats, and the transverse and longitudinal bamboo slats are fastened together by rattan cords. The fabrication of this structure of bamboo furniture requires much time and labor, and therefore the cost of this structure of bamboo furniture is high. There is also another design of bamboo storage container invented by the present inventor, which comprises a top frame, a bottom frame, and a plurality of bamboo slats connected between the top frame and the bottom frame. The bamboo slats have the respectively top and bottom ends respectively fastened to respective bottom mounting holes on the top frame and respective top mounting holes on the bottom frame. Because the bamboo slats are springy, it requires much time and labor to fasten the bamboo slats to the top frame and the bottom frame. Further, the top frame and the bottom frame are each formed of four bamboo slats, and the four bamboo slats are connected to one another end to end to form a rectangular open frame. The fabrication of this design of bamboo storage container also requires much time and labor. Therefore, this design of bamboo storage container is not suitable for mass production. Further, the top frame and the bottom frame have sharp angles, having less sense of beauty. EP1452659A discloses a process for cutting, bending and joining bamboo strips. SUMMARY OF THE INVENTION The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a bamboo frame member fabrication method, which is practical for mass production of bamboo frame members for making bamboo baskets that cause an unique sense of beauty. According to the present invention, bamboo poles are cut into straight bamboo strip elements and then the bamboo strip elements are processed into curved bamboo rod members through a compression molding press so that the curved bamboo rod members are selectively used and connected end-to-end to construct rectangular, circular and oval bamboo frame members for making bamboo baskets. The curved bamboo rod members can be selectively connected together end-to-end to construct rectangular, circular and oval bamboo frame members by means of an adhesive, plug joint, or fastener means. The bamboo rod members include M-shaped and L-shaped bamboo rod members. Four L-shaped bamboo rod members, two M-shaped bamboo rod members, or one M-shaped bamboo rod members with two L-shaped bamboo rod members can be connected together end-to-end to construct a rectangular bamboo frame member. The bamboo rod members include also arched bamboo rod members. Four 45° arched bamboo rod members, or two 90° arched bamboo rod members, or one 90° arched bamboo rod members with two 45° arched bamboo rod members can be connected together end-to-end to construct a circular bamboo frame member. 2, 3, or 4 arched bamboo rod members can be connected together end-to-end to construct an oval bamboo frame member. The number of bamboo rod members that construct one bamboo frame member can be 2, 3, 4, or more without limitation. The rectangular, circular and/or oval bamboo frame members can be used and connected with slats and/or blocks to construct bamboo baskets.
