为蚕沙的资源化可持续科学利用提供参考,以云烟85为试验材料,采用田间小区试验研究蚕沙发酵有机肥不同施用量对烤烟产质量的影响。结果表明:施用750kg/hm~2蚕沙发酵有机肥云烟85烟叶的产量和均价最高,分别为2 522.25kg/hm~2和51 353.17元/hm~2,比常规施肥(CK)增加5.0%和8.13%;施用1 500kg/hm~2蚕沙发酵有机肥的上、中等烟比例最高,分别为44.55%和47.89%,比常规施肥分别增加4.18百分点和1.91百分点。施用750~1 500kg/hm~2蚕沙发酵有机肥可显著提高云烟85烟叶的产质量和中上等烟比例,且烟叶内在化学成分协调。
This paper provides a reference for sustainable scientific utilization of silkworm excrement. Taking Yunyan 85 as experimental material, the field plot experiment was conducted to study the effects of different application rates of silkworm excrement organic fertilizer on the yield and quality of flue-cured tobacco. The results showed that the yield and the average price of the organic fertilizer Yunma 85 which applied 750kg / hm ~ 2 silkworm excrement were the highest, which were 2 522.25kg / hm ~ 2 and 51 ~ 353.17yuan / hm ~ 2, respectively, % And 8.13%, respectively. The highest proportion of middle and upper middle-grade tobacco leaves with application of 1 500kg / hm ~ 2 silkworm excrement were 44.55% and 47.89% respectively, which increased 4.18% and 1.91% respectively compared with the conventional fertilization. Application of 750-1 500 kg / hm2 silkworm excrement organic fertilizer can significantly improve the yield and quality of Yunyan 85 tobacco and the proportion of middle-high tobacco, and the chemical composition of the tobacco internal coordination.
