在马来西亚,自五十年代初,就进行借助梯子割高剖面的试验。试验证明,在老的实生树和芽接树的高割面原生皮上割胶能获高产。试验表明,降低割胶频率,割高、低两个割面,则更为有利。高低两割面两条半螺旋线、隔2日或隔3日割的两种制度(2·(1/2)S·d/3·H/L或2·(1/2)S·d/4·H/L)已在马来西亚广泛采用。 In Malaysia, since the early 1950s, experiments have been carried out to cut high sections with ladders. Trials have shown that high yields can be obtained by tapping the high-cut primary hide of the old and secondary trees. Experiments show that reducing the tapping frequency, cut high, low cut two, it is more favorable. Two half-spirals of high and low cut surfaces, two systems separated by 2 or 3 days (2 · (1/2) S · d / 3 · H / L or 2 · (1/2) S · d / 4 · H / L) has been widely adopted in Malaysia.
