摘要:
选择重庆市山地烟区就地取材的有机物料进行堆肥试验,优选出有机物料最佳配比的烤烟专用有机肥产品,明确不同配比有机肥产品对烤烟的产、质效应。结果表明:各种参试有机肥与对照相比均显著提高了烤烟上中等烟的比例、产量和产值,C/N比较高的有机肥(M3、M4和M5)与饼肥和常规有机肥相比,显著提高烟叶上中等烟比例,3种高C/N比有机肥对烤烟生长、烟叶品质和烟叶协调性的作用都优于饼肥或常规有机肥。这可能是高C/N比有机肥对土壤微生物数量和土壤肥力改善的综合作用结果。因此,在重庆市烟叶生产中,根据产区实际情况,推荐施用高C/N比的有机肥代替现行的饼肥和常规有机堆肥,应用有机物料与烟杆一起发酵生产的有机肥是一种肥效较好、环境友好的有机肥。

Abstract:
The organic material in Chongqing were selected to conduct composting test in order to screen the optimal proportion for fabricating the organic fertilizer products for flue-cured tobacco. The results showed the organic fertilizers could increase the proportion of superior middle, yield and quality of flue cured to bacco compared with the control. The high C/N organic manure (M3, M4 and M5) could significantly increase the proportion and output value of the superior middle of the tobacco leaves. The organic fertilizers (M3, M4 and M5) had the best effect on the nutrient uptake and growth of flue-cured tobacco. The effect of three kinds of high C/N ratio organic fertilizers on the growth of flue-cured tobacco, the quality of tobacco leaves and the coordination of tobacco leaves were better than the current applied cake fertilizer or the mixture of cake fertilizer and farmyard manure, which may be attributed to the comprehensive effects of high C/N ratio on the number of soil microbes and the improvement of soil fertility. In short, in the current tobacco production in Chongqing, the application of organic manure with high C/N ratio, especially the organic manure with the tobacco rod replacing the current cake fertilizer and farmyard manure, is an ideal organic fertilizer in improving tobacco quality effectively.
Key words:  Flue-cured tobacco  Organic fertilizer  Screening  Fertilizer efficiency validation
