摘要：

木醋液是生物炭制成过程中所产生烟雾冷凝形成的液体，本试验旨在研究木醋液对水稻生长发育及产量的影响。以水稻‘天两优14’为试材，用稀释100和300倍的木醋液，分别在分蘖期、孕穗期和抽穗期喷施1~3次，测定农艺指标。结果表明，除稀释100倍木醋液喷施1次处理外，喷施不同稀释倍数及不同次数的木醋液均能提高水稻产量1.7%~16.9%，生物量10.0%~24.8%，有效穗数12.7%~23.7%，总粒数6.2%~22.3%，实粒数6.6%~18.8%。同时显著提高了水稻的株高2.7%~9.2%，分蘖数10.9%~46.7%，SPAD 2.1%~27.1%。以稀释300倍喷施2次和3次的增加效果较好，且喷施2次与3次之间没有显著性差异。综上，稀释300倍的木醋液可促进水稻的生长且提高水稻的产量，一般以分蘖期和孕穗期各喷施1次施用效应更好。

Abstract:

Wood vinegar is formed by the condensation of smoke generated during biochar production. This experiment was conducted to study the effect of wood vinegar on rice growth and yield. Rice variety ‘Tianliangyou 14’ was used as experimental material, and 100 and 300 times diluted wood vinegar was sprayed 1-3 times at tillering, booting and heading stages, respectively, to determine agronomic indexes. The results showed that spraying wood vinegar with different dilution times at different growth stages increased the rice yield by 1.7%-16.9%, and the biomass by 10.0%-24.8%, the number of effective panicles by 12.7%-23.7%, the total number of grains by 6.2%-22.3%, the number of effective grains by 6.6%-18.8%, except for spraying wood vinegar one time with 100 times dilution. Meanwhile, the plant height of rice was significantly increased by 2.7%-9.2%, the number of tillers was increased by 10.9%-46.7%, and SPAD was increased by 2.1%-27.1%. The effect of spraying two or three times with 300 times dilution was better, and there was no significant difference between spraying two and three times. In summary, wood vinegar with 300 times dilution can promote rice growth and increase rice yield. Generally, it is a good strategy to spray once at the tillering and booting stages, respectively.
