摘　　要：本文研究了不同播种期对夏枯草产量的影响。结果表明:播种太早,夏枯草出苗率低,苗势弱,产量低;播种太晚,发棵晚,生长时间不足,产量受到影响。“白露”前后是夏枯草最适播种期,此时气温适宜,出苗快,单株重和产量显著高于其他播种期。合理安排夏枯草播期和中稻(或一季晚稻)的播期,可实现夏枯草—水稻一年二熟,种植效益显著提高。This paper studied the effects of different sowing dates on the yield of Prunella vulgaris L.The results showed that early sowing would lead to low emergence rate,weak seedling vigor and low yield of Prunella vulgaris L.;late sowing would lead to late growth,insufficient growth time,and the yield would also be affected.The optimum sowing time was around the"White Dew",the temperature was suitable and the seedling emergence was fast at that time,the weight of single plant and the yield were significantly higher than those at other sowing dates.Reasonable arrangement of the sowing date of Prunella vulgaris L.and middle-season rice(or single cropping late rice)could realize two crops a year,and the planting benefit significantly increased.
