衡南烟草蚯蚓粪肥应用效果研究

摘要

Objective] This study was conducted to investigate the effect of earth-worm manure on agronomic traits, yield and quality of flue-cured tobacco. [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.%[目的]研究蚯蚓粪肥施用对烤烟农艺性状以及产质量的影响。[方法]通过布置大田小区试验，研究基施蚯蚓粪肥不同用量对烤烟生长及经济效益的影响。[结果]施用蚯蚓粪肥均能不同程度促进烟株营养生长，提高上等烟叶产量与产值，不同施用量以基施4500 kg/hm2蚯蚓粪肥效果最佳，可显著提高上等烟叶比例与烟叶总产值，提高效益，维持烟田可持续生产能力。[结论]为蚯蚓粪应用于植烟土壤改良提供理论依据。
