烟桐间作不同结构对烟草产量和质量的影响

Influence of Intercropping Paulownia and Tobacco on Tobacco Yield and Quality

研究了烟桐间作不同结构对烟叶产量和质量的影响。结果表明,泡桐行距越窄,对烟叶CO_2同化量的影响越大,产量越低;反之,产量越高;烟叶质量随着泡桐行距缩小,总糖百分比含量降低,总氮和蛋白质含量增高;烟碱、烟碱氮含量比例不协调。但根据对产量和质量影响的范围大小,在5×60m 中间带为宜种烟区,在该区的东西冠下至冠外14m 宽范围及5×40m,5×20m 的间作地,为不宜区。

On the basis of the space in the rows of paulownia(5×60m,5×40m,5×20m)intercropping type of paulownia and tobacco,the authors set forth theinfluence on the quantity and quality of tobacco.The narrower the space inrows of paulownia,the more influence to the assimilation of tobacco CO_2 andthe lower the output;conversely,the higher the output.Influence to the qual-ity along with the reduction of space in rows of paulownia,carbohydrate con-tent of percentage reduces,nitrogen and protein increase and the proportion ofnicotine and nicotine-nitrogen doesn't coordinate.According to the influenceof the quantity and quality,among the 5×60m zone is good for growing toba-cco.
