| 摘 要： | 为了筛选合适的辣椒漂浮育苗基质,测定了3种不同基质处理下漂浮育苗中辣椒种子萌发及幼苗生长相关指标。结果表明:不同基质处理对辣椒种子萌发指标的影响差异显著,2号基质处理下3个辣椒品种发芽率、发芽势、发芽指数和发芽天数均明显高于1号、3号基质处理,甜椒的发芽率、发芽势、发芽指数和平均发芽天数分别为89%、53%、43.23和8.76,卡宴线椒为81%、48%、40.22和10.86,巨人椒为86%、50%、42.67和11.27;在4次采样中,仅在20d时2号基质处理下辣椒幼苗的株高、生物量、叶绿素SPAD值及全氮、磷、钾含量显著高于1号、3号基质,在30、40、50d的采样中上述指标在3个基质间差异不显著。综上所述,2号基质更适合在辣椒漂浮育苗中使用。

| Abstract: | In order to select suitable floating system substrate for pepper, the germination characteristics and
seedling growth indexes of pepper under three different substrates were studied. The results showed that the effects of
different substrates on seed germination indexes were different significantly. The germination rate, germination
potential, germination index and germination days of three varieties on substrate No. 2 were obviously higher than
those of substrate No. 1 and substrate No. 3. On substrate No. 2, the germination rate, germination potential,
germination index and germination days of sweet pepper were 89%, 53%, 43.23, 8.76, respectively, and 81%, 48%,
40.22, 10.86 for Kayan pepper, 86%, 50%, 42.67, 11.27 for giant pepper. In the period of four sampling, only on the
20th day the plant height, biomass, chlorophyll SPAD value and nitrogen, phosphorus, potassium content of substrate
No. 2 significantly were higer than those of substrate No. 1 and substrate No. 3, and the differences were not obvious
between three substrates in the 30th, 40th, 50th day. In summary, substrate No. 2 is more suitable for pepper floating
seedling. |
