摘要

通过对1，2年生白刺实生苗及野生移植苗接种锁阳，同时采用不同施肥方式、不同接种方式及接种量等处理对锁阳寄生出土效果的影响进行了研究。结果表明，白刺实生苗与野生移植苗在接种锁阳后2a锁阳出土较少，第3a为锁阳出土高峰期，其后出土率明显下降；1，2年生白刺实生苗接种锁阳2a累计锁阳寄生率分别为9.38%，25%，其远高于野生白刺移植苗在自然环境下的寄生率(4.12%，7.47%)；2年生白刺实生苗接种锁阳效果好于1年生白刺实生苗；在14个月的时间内，锁阳种子便与寄主发生寄生关系并生长出土，完全打破过去认为的至少需要2~4a的时间才能产生寄生关系并出土；在施肥量、接种量一致的情况下穴状施肥接种方式锁阳寄生出土效果好于营养床施肥接种方式，接种量增加能提高锁阳的寄生出土率及单位面积产量。

Abstract

By inoculation with Cynomorium songaricum to seedling and wild transplant of one or two year-old Nitraria tangutorum

the parasitic and emergency efficiencies of Cynomorium songaricum were studied un- der such treatments as different fertilization ways and different inoculation ways and amounts.Results showed that emergency of Cynomorium songaricum was less after inoculated for two years.The third year after inoculation was the emergency peak period and from then on

its emergency rate decreased significantly.Cumulative parasitic rates for two years of inoculation with Cynomorium songaricum to seedling of Nitraria tangutorum were respectively 9.38%and 25%

which was more than wild transplant parasitic rates of Nitraria tangutorum in natural environment(4.12%and 7.47%).Inoculation efficiency of two year-old seedling of Nitraria tangutorum was better than one year old seedling

whose seeds produced parasitism with host and emerged in the period of 14 months.This finding broke the past idea that producing parasitism and emerging needed 2-4 years at least.Under the consistent condition of fertilization and inoculation amounts

the parasitic and emergency effects of Cynomorium songaricum by cavernous fertilization were better than those by nutrient bed-fertilization.The increase of inoculation amount could improve emergency rate of Cynomorium sonnaricum and its yield per unit area.
