本文报导了第5割龄橡胶树无性系GT1采用不同浓度乙烯利刺激,结合不同割胶制度连续7年试验的结果,总的效应是刺激处理区的干胶产量为常规割胶对照区产量的106.8～116.6％,达显著差异,刀产干胶为对照的113.97～141.19％,干胶含量比对照偏低3.2～4.6％,其它生理参数也有差异。试验还表明,短期刺激产量与其它生理参数受刺激浓度和割胶制度的影响较大,长期连续用乙烯利刺激割胶,无论对干胶单株产置,刀次产量或其它生理参数与不刺激处理之间的差异都在逐渐缩小。试验认为,过早地在第一割面进行乙烯利刺激割胶,或刺激的头几年过度采胶,都会影响胶树第二割面产量,高低线轮换可减轻割面疲劳,有利于胶树健康。
In this paper, the results of continuous 7-year experiment with different concentrations of ethephon GT5 and different tapping systems were reported. The total effect is that the dry glue production in the stimulation-treated area is 106.8-116.6 %, Respectively. There were significant differences between the two groups (113.97% to 141.19%) and dry glue (3.2% -4.6%). The other physiological parameters were also different. The experiment also showed that short-term stimulation yield and other physiological parameters were influenced greatly by stimulus concentration and tapping system. Ethanol was used to stimulate tapping continuously for a long time. No significant differences were observed in the production of dried adhesive per plant, knife yield or other physiological parameters and non-stimulation The differences are gradually narrowing. Tests believe that premature ethephon in the first cut surface to stimulate the tapping, or stimulation of the first few years over-plastic, plastic will affect the second cut surface yield, high and low line rotation can reduce the fatigue, is conducive to plastic trees health.
