The results showed that, the field growth periods of various treatments were 117-118 d, 1-2 days longer than that of the CK. The numbers of effective leaves of the treatments applied with vermicompost were 0.1-0.3 leaf more than the CK. The highest yield and the highest proportion of high-grade tobacco occurred in treatment 3 as 2 095.5 kg/m^2 and 49%, respectively, which were higher than those in the CK by 6.58 kg and 5.3%. In conclusion, the treatment with the application of vermicompost at 7 500-10 500 kg/hm^2 was the best.展开更多

[Method] A field experiment was carried out to investigate the effects of different amount of earthworm manure on growth and economic benefit of tobacco. [Result] The results showed that： the application of earthworm manure could promote vegetative growth of tobacco to different degrees, and significantly increase high-grade tobacco yield and output value, thereby increasing the total output value of tobacco. Among the different application amounts, basal application of earthworm manure 4 500 kg/hm2 could significantly increase the proportion of high-grade tobacco and tobacco output, improve benefit and maintain sustainable production capacity. [Conclusion] This study provides a theoretical basis for the improvement of tobacco-planting soil with earth-worm manure.展开更多
