【摘要】：为探讨配施含芽孢杆菌和EM(effective microorganisms,EM)菌的复合生物有机肥对烤烟光合生理特性及土壤微生物的影响,通过对该复合生物有机肥不同配施量与单施化肥的对比,分析打顶7 d后烤烟生长发育与光合生理特性、烟叶经济性状与经济效果指数(economic character index,ECI)和化学成分可用性指数(chemical components usable index,CCUI),以及土壤微生物的影响,结果表明:与单施化肥相比,配施复合生物有机肥处理的净光合速率、上等烟比例、均价、产量和产值、烟叶经济效果指数(ECI)分别提高15.0%~18.1%、6.84%~9.50%、2.86%~3.70%、9.91%~11.90%、13.0%~16.0%,上部橘黄2级(B2F)和中部橘黄3级(C3F)烟叶可用性指数(CCUI)比单施化肥处理分别提高了5.78%~6.06%和3.54%~5.28%,土壤中的三大微生物细菌、真菌和放线菌总量显著高于单施化肥的处理。上述结果揭示复合生物有机肥在南方烟稻轮作区植烟土壤上的使用效果,为植烟土壤改良提供新的技术措施。
[Abstract]:In order to study the effect of compound organic fertilizer containing Bacillus spp and EM(effective microorganismemma on photosynthetic physiological characteristics of flue-cured tobacco and soil microorganism, the effects of different amount of compound biological organic fertilizer and single application of chemical fertilizer on the photosynthetic physiological characteristics of flue-cured tobacco were studied. The effects of chemical components usable index and soil microorganism on the growth and development of flue-cured tobacco after 7 days of topping, economic character index and economic effect index of tobacco leaf, chemical components usable index and soil microorganism were analyzed. The net photosynthetic rate, the proportion of superior tobacco, the average price, the yield and the output value of the combined biological organic fertilizer treatment, The index of economic effects of tobacco leaves (ECI) increased 15.0 and 18.1and 6.84, respectively, and increased 5.786.06% and 3.545.285.05%, respectively, and increased 5.786.06% and 3.545.285.28%, respectively, and increased 5.786.06% and 3.545.2850%, respectively, compared with the treatment of chemical fertilizer alone, and increased 5.786.06% and 3.545.2850%, respectively, and the three major microbes in the soil were increased by 5.786.06% and 3.545.285.28, respectively. The total amount of fungi and actinomycetes was significantly higher than that of chemical fertilizer alone. The above results revealed the application effect of compound biological organic fertilizer on tobacco planting soil in southern tobacco and rice rotation area and provided new technical measures for the improvement of tobacco planting soil.
