一、主要成分与配方

草炭土（泥炭土）：约占40-50%，选用东北高寒地区优质草炭，有机质含量高，纤维结构好，保水保肥能力强，是营养土的主要骨架成分。

腐熟有机肥：约占15-20%，以腐熟农家肥和食用菌菌渣为原料，经高温好氧发酵无害化处理，富含有机质和有益微生物，能持续释放养分，改善土壤微生物环境。

珍珠岩：约占10-15%，经高温膨胀而成的白色颗粒，质地轻盈，透气性极佳，能有效防止土壤板结，增加基质孔隙度，促进根系呼吸。

蛭石：约占10-15%，经高温膨胀而成的云母类矿物，具有良好的保水性和阳离子交换能力，能吸附和释放养分，保持基质水分稳定。

椰糠：约占5-10%，由椰子外壳纤维加工而成，环保可再生，保水性好，能改善基质结构，增加有机质含量。

营养元素：添加适量氮磷钾复合肥和微量元素，包括氮（N）≥1.0g/L、磷（P₂O₅）≥0.5g/L、钾（K₂O）≥1.0g/L，以及铁、锰、锌、硼、铜、钼等微量元素，能满足植物初期生长需求。

pH值：5.5-6.5，微酸性，适合大多数花卉植物生长。

EC值：≤1.5mS/cm，盐分含量低，不会烧根，适合幼苗和敏感植物。

八、常见问题解答

1. 营养土可以直接种花吗？

可以。绿康源通用型营养土已按科学配比完成基质调配，开袋即可直接用于盆栽花卉、蔬菜育苗和多肉种植，无需额外添加园土或肥料。对于大型盆栽或喜肥植物，建议在种植后1-2个月开始追施有机肥。

2. 营养土和普通园土有什么区别？

营养土是以泥炭、椰糠、珍珠岩、腐熟有机肥等为原料的人工调配基质，具有疏松透气、保水保肥、无菌无虫卵的特点；普通园土容易板结、透气性差且可能携带病菌和杂草种子。盆栽环境优先选用营养土，地栽可将营养土与园土按1:1混合改良土壤。

3. 营养土可以重复使用吗？

可以重复使用，但建议每茬作物后进行处理。将使用过的营养土摊开晾晒2-3天，去除残根和杂物，然后按旧土70%+新营养土30%的比例混合，并补充少量腐熟有机肥即可再次使用。连续使用超过3茬的旧土建议用于地栽改良，不再用于盆栽。

4. 营养土需要额外加肥料吗？

营养土中含有基础养分，可满足植物初期1-2个月的生长需求。之后需根据植物种类定期追肥：观叶植物每1-2个月施一次氮肥为主的有机肥，观花植物在孕蕾期增施磷钾肥。推荐配合使用绿康源园艺有机肥，肥效温和持久，适合各类盆栽花卉。
