自2004年,3 a来研究了六盘山林区野生濒危物种—桃儿七种子的不同处理方法和播种季节对出苗率的影响,结果表明,种子在冬季沙藏(或雪藏)3个月以上,由于经过了一个较长的休眠期,出苗率较高且整齐;种子春季、秋季水浸10d后播种的出苗率较低且不整齐。因此,采用冬季沙藏(或雪藏)桃儿七种子的繁育方法可以在本地区大面积推广。 Since 2004, 3 years to study the Liupanshan forest endangered species - peach seven seeds of different treatment methods and sowing season on the emergence rate, the results show that the seeds in winter sand (or snow) for more than 3 months , The germination rate was higher and neat due to a longer period of dormancy. The seeding rate of seed in the spring and autumn seasons was lower and irregular. Therefore, the use of winter sand (or snow) peach seven seed breeding methods can be widely promoted in the region.
