酒泉市由于气候干燥,大果沙棘在采用传统全光照喷雾嫩枝扦插技术育苗时,为了控制其湿度喷雾次数增加,而导致插床温度下降,使其成苗率低、生长量小。为此,本研究采用在无立柱拱棚内安装全光照喷雾设备,进行创新大果沙棘嫩枝扦插育苗技术,重点要解决基质不积水而保证插条需水,扦插时间最好在6月15日至7月1日间,扦插处理用比较温和的硅酚环等生根剂处理为宜。结果在成苗率和生长量方面均得到较好的效果。提高了大果沙棘就地繁育优良种苗的效率。 Jiuquan City, due to dry climate, large fruit seabuckthorn in the traditional full light spray softwood cutting technology nursery, in order to control the humidity spray number increased, resulting in the temperature fell into the slot, so that the seedling rate is low, small growth. Therefore, in this study, the installation of full-illumination spraying equipment in column-free arch shed was used to innovate the softwood cutting technology of seabuckthorn. The key was to solve the problem that the matrix did not accumulate water and ensure the water requirement of cuttings. The best cutting time was June 15 Day to July 1, cutting treatment with a more gentle silicone ring and other root agent treatment is appropriate. Results in seedling rate and growth rate have been better results. Improve the efficiency of high-quality sea buckthorn seedlings in situ breeding.
