摘 要:采用田间小区试验,研究了木醋液不同灌溉量对土壤养分、盐碱和番茄产量及品质的影响。结果表明,土壤灌溉木醋液可提高土壤碱解氮、速效钾、有效磷含量,且使用量越大,效果越明显,其中有效磷含量增加最为显著,与对照相比可提高9.27%~25.51%;木醋液也可提高土壤有机质及全盐含量,但与对照相比差异不显著;木醋液还可降低土壤p H值,与对照相比可降低0.14~0.27个单位。木醋液低[2.25 t/(次·hm^2)]、中[4.50 t/(次·hm^2)]用量能显著提高番茄株高、增加产量,其中低用量效果最好,与对照相比可提高株高10.53%,增加产量11.52%;高用量[7.50 t/(次·hm^2)]对番茄生长具有一定抑制作用。木醋液可提高番茄可溶性糖含量5.27%~10.28%,提高Vc含量3.46%~17.15%,降低硝酸盐含量4.25%~15.33%,对有机酸含量影响不明显。综上所述,建议设施土壤番茄季木醋液灌溉量为2.25~4.50 t/(次·hm^2)为宜。A field plot experiment was conducted to study the effect of wood vinegar on soil nutrient,salt,tomato yield and quality in greenhouse. The result showed that wood vinegar improved soil available nitrogen,available potassium and available phosphorus content,and the more wood vinegar used,the effects were more obvious,especially for in the available phosphorus which was increased by 9. 27% ~ 25. 51% than that of the control. Soil organic matter and total salt content were also improved by using wood vinegar,but was not significant compared with the control. Wood vinegar reduced soil p H by 0. 14 ~ 0. 27. The low and middle amount of wood vinegar significantly increased the amount of plant height and yield. The low amount of wood vinegar was best,in which plant height and yield were increased by 10. 53% and 11. 52%,respectively. However,applying wood vinegar with high amount inhibited the growth of tomato. Applying wood vinegar increased tomato soluble sugar content from 5. 27% to 10. 28%,enhanced Vc content from 3. 46% to 17. 15%,reduced nitrate content from 4. 25% to15. 33%,but there was no significant effect on the organic acids content. In summary,the proposed irrigation amount of wood vinegar was 2. 25 ~ 4. 50 t/( times·hm^2) in greenhouse soil at tomato season.
