摘　　要：本试验采用田间单因素随机区组设计,研究了加施破缕石坡缕石对藏木香产量、品质及土壤团粒结构的影响。结果表明：坡缕石用量750 kg hm-2~3000 kg hm-2时下,均能提高匙藏木香的产量和品质,3000 kg hm-2时产量最高,根径最粗、主根最长、植株最高,且较对照极显著增产29.43%（P〈0.01）;2250 kg hm-2多糖含量最高,品质最优;坡缕石能显著增加直径〉0.25mm和0.25～0.5 mm团聚体总数。这一研究结果在藏木香栽培中科学合理的将N、P、K肥料与破缕石配施是提供了科学依据。The single factor randomized block is designed in the field experiment, and effects of playgoskite are studied on the growth, yield, quality and soil aggregate of Inula helenium I. Results show that playgoskite can enhance the yield and quality of Inula helenium I., when it is used in scopes of 750 kg hm-2 - 3000 kg hm-2. And the yield is the highest, root diameter is the thickest, root length is the longest, and plant is the highest, when it is added 3000 kg hm-2. And the yield is increased by 29.43% （P 〈 0.01 ）compared to the CK. And contents of alantolaction are the highest, so the quality is also most superior. Playgoskite markedly increases aggregate numbers of the diameter above 0.25 mm and from 0.25 to 0.5. This study＇s results reasonably provide an important scientific basis for the cultivation of Inula helenium I. by employing the rational combinations of N, P and K fertilizers as well as playgoskite.
