热研7-33-97幼龄开割树对低频刺激割制的适应性研究初报

Adaptability of Young Tapped Hevea Brasiliensis var. SCATC 7-33-97 to Lower Frequency Tapping System with Stimulants

研究了速生高产优良无性系热研7-33-97在幼龄开割期对低频刺激割制的适应性。3a结果表明,该品种在幼龄开割期使用低频乙烯利刺激割胶表现出胶乳再生能力强、用于生长的干物质分配率高、排胶速度快等生理特性。采用低频、短线、少药等技术措施,有利于胶树的产胶与生长。

Experiments were made on the adaptability of the fast-growing and high-yielding clone of Hevea Brasiliensis var. SCATC 7-33-97 at young stage to lower frequency tapping system with stimulants. The results showed that SCATC 7-33-97 showed strong ability in latex reproduction, high allocation rate of dry matter, and rapid flow of latex when tapped with ethrel stimulation at its early tapping period. The measures of lower tapping frequencies, shorter tapping cuts and smaller stimulant dosages were helpful to latex production and growth of the rubber trees.
