漆树种子的种皮由木质化的多细胞壁角质层构成,质地坚硬,并含有蜡质,不易透水、透气,妨碍种子发芽。因此,春播育苗时需要催芽。大量种子集中在春季播种育苗,时间紧,任务重,有时往往和春耕生产争劳力、争对间。若遇春旱、春涝等不良气候,经催芽的种子播种后不是干瘪脱水死亡,就是幼根因病菌腐烂,影响育苗质量和数量。从1962年以来,不少地方进行冬播育苗,育苗成效甚好。具体做法是:
The seed coat of the lacquer tree seed consists of a lignified multicellular wall cuticle that is hard in texture and contains waxy, impermeable, breathable, preventing seed germination. Therefore, spring nursery need to germination. A large number of seeds concentrated in the spring planting nursery, time is tight, heavy tasks, and often struggle with the spring production of labor, fight for. In case of spring drought, spring floods and other undesirable climate, the germinated seeds are not sown after dehydration death, that is, young root rot due to bacteria affect the quality and quantity of nursery. Since 1962, many places have conducted winter sowing and nursery and seedling breeding has done very well. The specific approach is:
