用直播遮阳、移栽遮阳和移栽全光3种育苗方式,通过测定苗高、叶数和地径以及生物量等指标,分析其对不同时期苗木生长的影响。研究结果表明:在移植后8个月内不同培育方式的苗高生长有显著差异,但之后差异不显著;叶数仅在翌年3月存在显著差异。当培育苗木高度不超过30 cm或培育周期短的,宜采用移栽全光育苗方式;当培育高度30 cm以上或培育周期较长的,可根据实际采用任一种育苗方式。
The effects of direct sunlight, transplanted shading and transplanted whole seedlings on seedling growth were analyzed by measuring seedling height, leaf number, diameter and biomass. The results showed that there was a significant difference in seedling height growth among different cultivation methods within 8 months after transplantation, but the difference was not significant afterwards. The number of leaves was only significantly different in March next year. When the nursery stock height does not exceed 30 cm or the incubation period is short, it is advisable to adopt the transplanting all-photoperiod-seedling mode. When the nursery height is above 30 cm or the incubation period is longer, any seedling-raising method may be adopted according to the actual situation.
