摘要(Abstract):

该文采用盆栽土培试验,研究了施用氯化钾和硫酸钾及配施对三七生长、产量和品质的影响。结果表明,同对照相比,氯化钾和硫酸钾及两者配施均能显著提高三七生物量和产量,且氯化钾对三七增产效果略优于硫酸钾。2种钾肥及配施均也显著促进三七植株对K的吸收和三七地下部对N,P的吸收,并显著提高三七皂苷含量与累积量;其中,三七皂苷R_1,人参皂苷Rg_1,Rb_1,Rd和总皂苷含量分别增加了54.54%~72.72%,11.15%~37.55%,2.26%~29.68%,10.34%~51.72%,13.85%~25.52%,且氯化钾和硫酸钾1:1配施时,三七各种皂苷成分含量最高。2种钾肥相比,氯化钾对皂苷成分含量的提升作用优于硫酸钾。三七对氯不敏感,氯化钾和硫酸钾对三七的生长发育及品质的形成作用等效。三七生产中推荐选用氯化钾做钾源,以提高三七产量和品质,降低钾肥投入成本。
In order to make sure whether Panax notoginseng is sensitive to chloridion and guide fertilization in planting of P.notoginseng,the effects of the different proportion of potassium chloride(KCl) and potassium sulfate(K_2SO_4) on the yield,quality of P.notoginseng were studied.The results showed that K fertilizer significantly improved the growth of P.notoginseng and increased the biomass per plant or per pot and the content of N,P,K and the content of saponin.In cases of conditions such as potassium,and the effects of K_2SO_4 on increasing the petiole length,leaf size,rhizome length,root length,and content and accumulation of Ginsenoside Rg,were better than those of KCl.While compared with K_2SO_4,KCl was more conducive to augmenting height,root width,the biomass of shoot,rhizome,root and the content of Ginsenoside Rb,and Rd.There was not remarkable difference in agronomic characters,biomass and the content of N,P,K among KCl,K_2SO_4 and the combination of KCl and K_2SO_4 However,the content of saponin of the treatment with combination of KCl and K_2SO_4 was significant higher than that of single KCl or K_2SO_4 treatments.K fertilizer significantly increased yield and the content of saponins.And P.notoginseng was not sensitive to chloridion.KCl increased the yield and the content of saponins of P.notoginseng as well as K_2SO_4,and the combination treatment was superior to single treatment.It is recommended that the KCl should be adopted in production,to reduce the cost of potash fertilizer.
