以梭梭和肉苁蓉为试验材料,研究了梭梭树龄与肉苁蓉种子产量的关系。结果表明:1)梭梭基径粗、株高、冠幅、肉苁蓉直径、花序长、蒴果数、有效果数、单蒴果重和单株种子产量与梭梭树龄呈显著正相关,相关系数在0.93以上。2)随着梭梭树龄增长,与对照相比,单株肉苁蓉种子产量提高了2～5倍。直径<0.5mm的种子所占比例下降,直径为0.5～0.7mm种子所占比例提高。3)5年生及以上的梭梭所寄生的肉苁蓉直径和花序长可达21.72mm和30.8cm以上,并且蒴果数、有效果数和单株种子产量分别可达143个、128个和11.810g以上。5年生及以上的梭梭可作为寄主培育肉苁蓉留种植株。
Taking Haloxylon ammodendron and Cistanche deserticola as test materials, the relationship between Haloxylon ammodendron seed age and Cistanche seed yield was studied. The results showed that: (1) The diameter of Haloxylon ammodendron, plant height, crown width, diameter of cistanche, inflorescence length, number of capsules, number of effective fruit, single capsule weight per plant and seed yield per plant were positively correlated with the age of Haloxylon ammodendron, Above 0.93. 2) With the growth of Haloxylon ammodendron, the seed yield of Cistanche deserticola increased by 2 ~ 5 times compared with the control. The proportion of seeds with diameter <0.5mm decreased, the proportion of seeds with diameter of 0.5 ~ 0.7mm increased. 3) The diameter and inflorescence length of Cistanche tuba parasitized by 5-year-old and above were up to 21.72mm and above 30.8cm, and the numbers of bolls, fruit number and single seed yield could reach 143, 128 and 11.810g respectively . Haloxylon ammodendron grown for 5 years and above can be used as host to cultivate Cistanche deserticola.
