采用正交试验,分析不同播种期(B1、B2、B3)和不同施肥方式(F0、F1、F2)对3种不同夏枯草品种(湖北蕲春品种,Q;江西樟树品种,J;河南确山品种,H)的产量和品质的影响,确定适合蕲春地区的品种及规范化栽培技术。结果表明:在施肥方式F2中,(1)在B1期,品种Q的鲜果球重、有效果球总数和干果球重都高于J和H品种(P﹤0.05),而迷迭香酸含量在3个品种中基本一致(0.36%以上),表明品种Q在B1期表现最佳;(2)在B2期,品种H的鲜果球重、有效果球总数和干果球重都高于其他2个品种(Q和J)(P﹤0.05),表明H品种在B2期表现较好;(3)在B3期,3个品种所有参数差异均无统计学意义。在施肥方式F1和F0中,3个品种的迷迭香酸含量在不同播期总体低于F2施肥方式。综合评价表明,品种Q为优先培育品种,其播种期为B1期,施肥方式为F2,而品种H可适度种植。

To screen high yield and good quality Prunella vulgaris L. varieties,which could besuitable for cultivation at Qichun areas,yield and quality of three Prunella vulgaris L. varieties(Hubei Qichun,Q;Jiangxi Zhangshu,J;Henan Queshan,H)were evaluated with an orthogonal experiment,according to the same plot,three different sowing dates(B1,B2,B3,respectively)and different fertilization treatments(F0,F1,F2,respectively). The results showed that:In F2 fertilization treatment,⑴ In the B1 period,wet weight,total effective number and dry grain of fruit ear of Qvariety were higher than that of J and H varieties(P < 0. 05),and rosmarinic acid content of threevarieties was consistent(more than 0. 36%),indicating that Q variety is better in the B1 period. ⑵In the B2 period,wet weight,total effective number and dry grain of fruit ear of H variety were higher than that in the other two cultivars(Q and J)(P < 0. 05),and rosmarinic acid content of three varieties was consistent(0. 27%⁰. 29%),indicating that H variety is better in the B2 period. ⑶ Inthe B3 period,all parameters of three varieties(Q,J,H)were no significant differences. The content of rosmarinic acid of the fertilization F1 and F0 in different sowing dates was lower than that ofF2 fertilization. Comprehensive evaluation showed that the Q variety could be used as the preferredcultivation and planting variety,with sowing date in the B1 period and F2 fertilization treatment, and the H variety could be moderately developed in Qichun areas.
