摘　　要：橡胶树‘热研7-20-59’是中国热带农业科学院橡胶研究所选育的高产晚熟品种,为探讨该品种应用气刺短线采胶技术的产量效应和技术适应性,在2018—2020年期间,在该品种上连续使用气刺短线采胶技术,并对其胶树死皮率和产量情况进行了分析。试验表明,连续3年使用气刺短线采胶技术,干胶产量逐年递增,2020年株产达到7.2kg,高于同割龄基本试验区株产,年平均四、五级死皮率低于0.5%。在‘热研7-20-59’上使用气刺短线采胶技术,既省工又高效,配合使用动态调控技术割胶,可实现连续3年增产。Rubber tree'catas7-20-59'is a high-yield and late-maturing strain selected by Rubber Research Institute of Chinese Academy of Tropical Agriculture.In order to study the yield effect and technical adaptability of technique of short-cut tapping with gas stimulation,from 2018 to 2020,this technique was continuously applied on rubber tree'catas 7-20-59',and then the tapping panel dryness incidence and yield were summarized.The test results showed that the production of dry rubber had been increased year by year,after using technique of short-cut tapping with gas stimulation for three consecutive years.In 2020,the individual rubber yield reached 7.2 kg,which was much higher than that in the advanced variety trial with the same cutting age,and the average tapping panel dryness incidence was lower than 0.5%.The application of technique of short-cut tapping with gas stimulation on'catas 7-20-59'was labor-saving and efficient.With the use of dynamic control tapping technique,the production increased for three consecutive years.
