大果无刺沙棘嫩枝扦插配套技术研究

摘要

Related fertilization ,transplant technology of softwood cuttings for Hippophae rhamnoides were studied .Result shows that:the effect of fertilization on Hippophae rhamnoides is significant ;taking molybdenum fertilizer as example , growth effect of dipped rooted seedlings with 1% concentration of fertilizer is optimal ;mixture ratio of nitrogen ,phosphorus and potassium is 1∶0 .4∶1;15-22-day-old transplanted cutting seedlings grew optimal before July 1;transplantation effect of seedlings with root length being 3-5 cm is optimal;survival rate & growth of cutting seedling on barren soil is optimal ;its re-sistance is strong .%对大果无刺沙棘嫩枝扦插育苗过程中相关的施肥、移植等配套技术进行了试验研究，结果表明：施肥对大果无刺沙棘扦插苗的生长影响显著，以钼肥为例，1％施肥浓度和蘸根处理的苗木生长效果最好，氮、磷、钾营养元素的配比为1∶0．4∶1最佳；7月1日以前（15～22 d扦插苗）移植的苗木生长质量较好；3～5 cm根长移植效果较好；裸地扦插苗成活率高，生长好，抗性强。
