望天树为国家Ⅰ级重点保护野生植物,是我国珍贵的用材树种之一。以望天树半年生优势苗作为采穗母株,采用GGR6号作为生根促进剂,对望天树嫩枝扦插育苗技术进行了初步研究。结果表明:(1)截干高度对母株产穗量影响显著,最适宜截干高度为20～30cm;(2)生根促进剂浓度对插穗生根影响显著,适宜浓度为800～1 000mg/kg;(3)扦插时间对插穗生根影响显著,扦插时间为3-7月。 Wang Tian tree for the national level Ⅰ key protected wild plants, is one of China’s precious timber species. Taking the semi-annual dominant seedlings of Hope tree as the spike mother plant, GGR6 was used as the rooting promoter to study the tender shoot cutting technology of Hope tree. The results showed that: (1) The height of truncated stem had a significant effect on the yield of female parent plants, and the optimum height of truncated stem was 20-30 cm. (2) The concentration of rooting promoter had a significant effect on the rooting of cuttings and the suitable concentration was 800-1 000 mg / kg ; (3) cutting time on cuttings rooting significant impact, cutting time for the March-July.
