连续6a观测了3个组合矮型橡胶三合树(光亮橡胶/巴西橡胶)开割后的生长、产胶表现。结果表明,三合树的树围增长量仅为对照的2/3,树高增长量明显小于对照,树冠冠幅的生长与对照基本持平,干胶产量仅为对照的43.1%,干含低于对照。
Six consecutive years observation and measurement of the growth and the yield of dwarf three -part rubber trees from three combinations after tap ping in di cated that the growths of the trunk and the crown of the dwarf three-part rubber trees were sim ilar to the control.The height of the trees was significantly shorter than the control.The yield and dry rubber content were lower than the control.
