| 摘 要： | 研究表明,采用盆栽法,在土壤中添加油菜秸秆生物炭可极显著提高土壤的pH值和有机质含量,但对土壤全氮、碱解氮含量无显著影响;添加生物炭可显著或极显著增加水稻的根系活力、总根长、总根表面积、总根体积、分蘖数、叶面积、叶片叶绿素含量以及水稻各部位(根、茎、叶)干物质量.综上,添加生物炭有利于改善土壤肥力,进而促进水稻苗期根系...

| Abstract: | A pot experiment was conducted to study the effects of adding rapeseed straw biochar on soil chemical properties and rice seedling growth. The results showed that adding biochar significantly increased pH value and organic matter content of the soil, but did not significantly affect total nitrogen and alkali-hydrolyzable nitrogen contents in the soil. Adding biochar significantly increased root activity, total root length, total root surface, total root volume, number of tillers, leaf area, leaf chlorophyll content, dry matter of rice. In summary, adding biochar is beneficial to improve soil fertility and consequently promote root and shoot growth of rice seedlings. |
