摘要
本文报道了木本能源植物红皮树种子的萌发特性,1年生播种苗的生长规律和等级划分等初步结果。提出贵州红皮树1年生苗划分为两个等级,Ⅰ级苗苗高≥20 cm,地径≥0.4 cm;Ⅱ级苗苗高≥15 cm,地径≥0.3:种子宜采用砂藏层积催芽春播,播种期宜在3月上旬至下旬,播种量控制在每平方米45g左右。
The seed germination characteristics and the seedling growth regulation of the woody energy plant, Styrax suberifolius Hook. et Am. , were studied. It was suggested that the seeds be stored in the sand with stratification way and sowed in March with sowing rate of 45g/m^2 . One - year - old seedlings were proposed to be divided into two grades： when the height is ≥20cm and the ground diameter is ≥ 0. 4cm, it belongs to Grade Ⅰ ; when the height is ≥ 15cm and the ground diameter is ≥0. 3cm, it belongs to Grade Ⅱ.
