为探索稻茬烤烟根区施用生物有机肥的效应,在湖南省桂阳县采用大田试验研究了生物有机肥根区施用对烤烟营养生长、光合特性、烟叶质量及经济效果的影响。结果表明:①稻茬烤烟根区施用生物有机肥较条施处理,团棵期最大叶面积可提高24.58%,打顶期茎围、最大叶面积、SPAD值、净光合速率、气孔导度、胞间二氧化碳浓度、蒸腾速率可分别提高4.72%、19.29%、14.78%、7.30%、22.64%、5.63%、32.14%,第1次采烤期SPAD值、净光合速率、气孔导度、胞间二氧化碳浓度、蒸腾速率可分别提高15.64%、23.82%、30.00%、8.31%、15.26%,有利烤烟营养生长,提高烤烟叶绿素含量和光合能力。②稻茬烤烟根区施用生物有机肥...

In order to explore the function of applied bioorganic fertilizer to root-zone soil under tobacco-rice rotation, a field experiment was conducted to study the effects of applied bioorganic fertilizer to root-zone soil on agronomic characters, photosynthetic characteristic, tobacco quality and economic characters in Guiyang County of Hunan Province. The results showed that compared with control (row fertilization), applied bioorganic fertilizer to root-zone soil could accelerate tobacco plant growth, improve chlorophyll content and tobacco leaf photosynthetic capacity, it increased the area of ...
