摘要
以2a生红叶石楠为材料,研究育苗方式、光照奈件、修剪强度、栽植密度、供水量、施肥量等不同栽培措施对红叶石楠红叶期及其叶片颜色的影响.研究结果表明:①红叶石楠组培苗的红叶期比扦插苗长;②红叶期随着光照强度增强而变长;③适当增加红叶石楠的修剪强度,有助于延长红叶期;④在红叶期,栽植密度越小,植株下部叶片颜色越深;⑤每隔10d左右浇一次水,有利于延长红叶期;⑥每隔10~15d施一次含3%左右的氮肥,有助于延长红叶期.
Taking :2-year red-leaved Photinia serrulata as materials, the study puts focus on the impact of diverse cultivation measures on red-leaved period and leaf color including seedling means, illuminative condition, pruning intensity, planting density, water supply and fertilizer amount. The results indicate as followed : ①the red- leaved period of tissue cultured seedling is longer than that of cutting seedling ; ②the smaller the planting density is, the deeper the color of leaves at lower position is;③the red-leaved period tends to be extended under such conditions namely strong illumination, proper increase of pruning, watering every other 10 days, and applying about 3% nitrogenous fertilizer every other 10 - 15 days.
