摘要： 为了促进苗木须根的萌发，提高植株移植的成活率，以凹凸壁多孔盆为育苗钵，通过不同基质研究其对草木樨、沙冬青幼苗生长的影响。结果表明：在基质1（蛭石）中、诱根钵中的苗木生长较普通盆(CK)的好，其中对草木樨地上部分和对沙冬青地下部分的促进作用更为明显。如：在诱根钵和基质1中草木樨的株高、叶片数、叶面积、主根长、须根数、植株地上部分鲜重、干重和地下部分鲜重、干重分别高于普通盆56.21%、65.00%、70.00%、21.00%、41.96%、61.11%、97.3%、11.56%、19.03%；沙冬青分别高于普通盆21.82%、4.44%、15.97%、38.28%、76.83%、18.76%、20.07%、57.84%、19.77%。在基质2中（蛭石+园土）诱根钵对2种植物地上部分的生长影响不如普通盆，但对其根系的生长有明显的促进作用。普通盆中均以基质2培养的2种植物幼苗生长好于基质1；诱根钵培养的草木樨也以基质2中的更好，但沙冬青相反，在基质1中更好。因此，诱根钵可以促进幼苗生长，但植物种类不同、基质不同，其效果不同。

Abstract: In order to encourage the growth of fibrous root and increase the survival rate of plantlet transplanted, seedling growth of Melilptus suaveolens Ledeb. and Ammopiptanthus mongolicus (Maxim.ex Kom.) Cheng f. was researched by induced root containers with porous protruberances surface (IRCPPS) and cultivation medium. The result showed that: growth of plants in IRCPPS was better than in common plastic pots with medium1, and particulaily overground part of Melilptus suaveolens and underground of Ammopiptanthus mongolicus. such as the plant height, leaf number, leaf area, main roots, fibrous roots, aboveground plant fresh weight, dry weight and the underground part of the fresh weight, dry weight of Melilptus suaveolens Ledeb. were 56.21%, 65.00%, 70.00%, 21.00%, 41.96%, 61.11%, 97.3%, 11.56%, 19.03% more respectively in IRCPPS filled by medium1 than in common plastic pots. Those indices of Ammopiptanthus mongolicus in IRCPPS were higher than ordinary pots 21.82%, 4.44%, 15.97%, 38.28%, 76.83%, 18.76%, 20.07%, 57.84%, 19.77%. The aboveground growth of two species in CK pots was better than in IRCPPS，but the growth of their roots was improved significantly. The plant seedling growth with medium2 in ck pots was better than with medium1; Melilptus suaveolens in IRCPPS with medium2 was cultured better, but Ammopiptanthus mongolicus was opposite, was better in the medium1. IRCPPS could promote the seedling growth, but effect of IRCPPS should be different with different plant species and different medium.
