The effects of additions of earthworm-processed pig manure (vermicompost) on the growth and productivity of French marigold (Tagetes patula) plants were evaluated under glasshouse conditions. Marigolds were germinated and grown in a standard commercial greenhouse container medium (Metro-Mix 360), substituted with 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100% (by volume) pig manure vermicompost. The control consisted of Metro-Mix 360 alone without vermicompost. Plants were supplied regularly with a complete mineral nutrient solution for 121 days. The greatest vegetative growth resulted from substitution of Metro-Mix 360 with 30% and 40% pig manure vermicompost, and the lowest growth was in the potting mixtures containing 90% and 100% vermicompost. Most flower buds occurred in the potting mixtures containing 40% pig manure vermicompost (19.4 buds), and fewest in the potting mixtures containing 100% vermicompost. Marigolds grown in Metro-Mix 360 substituted with 90% and 100% pig manure vermicompost had the fewest and smallest flowers. After substitution of Metro-Mix 360 with 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% vermicompost, the marigold roots were larger than those of plants grown in the Metro-Mix 360 controls. Substitution of Metro-Mix 360 with any concentration of pig manure vermicompost, with all needed nutrients provided, increased the overall nitrate-nitrogen concentrations of the marigold leaf tissues at flowering stage. Some of the marigold growth and productivity enhancement, resulting from substitution of Metro-Mix 360 with pig manure vermicompost, may be explained by nutritional factors; However, other, factors, such as plant-growth regulators and humates, might have also been involved since all plants were supplied regularly with all required nutrients.
在温室条件下评估了添加蚯蚓处理过的猪粪（蚯蚓堆肥）对法国万寿菊（孔雀草）植株生长和生产力的影响。万寿菊在标准商业温室容器培养基（美乐棵360）中发芽并生长，该培养基分别用10%、20%、30%、40%、50%、60%、70%、80%、90%和100%（按体积计）的猪粪蚯蚓堆肥替代。对照组仅为不含蚯蚓堆肥的美乐棵360。定期为植株供应完全矿质营养液，持续121天。用30%和40%的猪粪蚯蚓堆肥替代美乐棵360时，营养生长最为显著，而在含有90%和100%蚯蚓堆肥的盆栽混合物中生长最差。大多数花芽出现在含有40%猪粪蚯蚓堆肥的盆栽混合物中（19.4个花芽），而在含有100%蚯蚓堆肥的盆栽混合物中最少。生长在被90%和100%猪粪蚯蚓堆肥替代的美乐棵360中的万寿菊花朵数量最少且花朵最小。用20%、30%、40%、50%、60%、70%、80%和90%的蚯蚓堆肥替代美乐棵360后，万寿菊的根系比生长在美乐棵360对照中的植株根系更大。在提供所有所需养分的情况下，用任何浓度的猪粪蚯蚓堆肥替代美乐棵360，都会增加开花期万寿菊叶片组织中的总硝态氮浓度。用猪粪蚯蚓堆肥替代美乐棵360所带来的万寿菊生长和生产力的提高，部分可能是由营养因素所致；然而，由于所有植株都定期获得了所有所需养分，其他因素，如植物生长调节剂和腐殖酸盐，可能也起到了作用。
