引种栽培试验表明,观光木播种出苗率达82%,1年生苗生长较慢,第2年起生长加快。芽苗移植苗根系生长发育好于未移植苗,对移栽造林的幼树生长有促进作用。观光木在-10℃低温持续10 d时,幼苗幼树叶片受冻害程度随植株年龄增长而显著减弱,且能够恢复生机,表现出较强的适应性和抗寒性。
The introduction and cultivation experiments showed that the seedling rate of sightseeing wood was 82%, the growth of one-year-old seedlings was slow, and the growth was accelerated from the second year. The root system of bud transplanting seedling grew better than the non-transplanted seedling, which could promote the growth of young tree of transplanting and afforestation. When the sightseeing lumber was kept at the low temperature of -10 ℃ for 10 days, the degree of frost damage of the seedling saplings was significantly weakened with the increase of the plant age, and the vitality of the sightseeing trees could be restored, showing strong adaptability and cold resistance.
