增施蚕沙发酵有机肥烟叶的产质量变化

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。

Influence of Fermented Silkworm Excrement on Yield and Quality of Flue-cured Tobacco

Yunyan 85 was used as the experimental material to investigate the effects of fermented silkworm excrement on yield and quality of flue-cured tobacco,in order to provide references for the sustainable utilization of silkworm resources scientifically.Results:The application of 750 kg/hm2 of silkworm excrement had the highest yield and average price,which were 2 522.25 kg/hm2 and 51 353.17 Yuan/hm2 respectively,compared with CK increased by 5％ and 8.13％;The application of 1 500 kg/hm2 silkworm excrement had the highest upper middle smoke scale,which were 44.55％ and 47.89％ respectively,compared with CK increased by 4.18 and 1.91 percentage points respectively.Generally,the fermented silkworm excrement worked the best when it was applied at the rate of 750～1 500 kg/hm2.
