3个中国沙棘优良品种扦插技术研究

Studies on cutting technology of three elite breeds of Hippophae rhamnoides

针对辽西地区沙棘资源发展现状,以3个中国沙棘优良类型中红果、中黄果、中无刺为研究材料,对其苗木繁育技术进行了深入系统的研究。结果表明,采用炉渣灰扦插基质、ABT生根粉1号、插穗长度10cm左右、扦插时间为6月21日左右,这种处理效果最佳,但从经济角度考虑,最宜采用鲜河沙作为基质。中国沙棘苗木繁育采用裸地沙盘全光喷雾嫩枝扦插快繁技术效果较好。沙棘硬枝扦插的成苗率受多种因素的制约,硬枝扦插时间为4月下旬至5月初,采用20cm长的插穗,2~3年生的插穗成苗率较高,生产中采用2年生的插穗。

Based on the seabuckthorn resources development status in western Liaoning Province, three fine types of Hippophae rhamnoides were taken as study materials and systematic study on seedling breeding techniques were carried out. The results indicated that when material treated as follow: slag-ash used as cuttage substrate, ABT No. 1 used as rooting agent, cutting length was 10cm, cutting time was June 21 presented the best effect, but from the economic point, fresh river sand was the most suitable substrate. The best seedling breed technique for H. rhamnoides was green wood cutting with full light spray in sand table. The seedling rate of hardwood cuttings was affected by many factors. The suitable time for hardwood cutting was from late April to early May and suitable cutting length was 20 cm. The seedling rate of 2-3 years old cuttings was relatively high, and 2 years old cuttings were usually adopted in production.
