2、根系活力等反映根系特征的指標(biāo),研究前溜液灌根對(duì)草莓根系生長(zhǎng)的影響情況。結(jié)果表明,噴灑稀釋100倍的150、250oC前溜液的試驗(yàn)組草莓根系重量較空白對(duì)照組有顯著差異,能夠有效促進(jìn)根系鮮重和干重的增加;噴灑稀釋800倍的木醋液試驗(yàn)組草莓根系較空白對(duì)照組有顯著增長(zhǎng);噴灑稀釋100、800倍的250oC前溜液和稀釋1500倍的木醋液3個(gè)試驗(yàn)組草莓根系面積與空白對(duì)照組有顯著增長(zhǎng)。噴灑稀釋100、800倍的250℃前溜液和稀釋800倍的木醋液的3個(gè)試驗(yàn)組草莓根系活力較空白對(duì)照組增長(zhǎng)顯著,均增加4倍以上。試驗(yàn)證明適當(dāng)濃度的前溜液和木醋液均能不同程
