摘要本研究研究了岩尘堆肥对江苏省成熟苹果园土壤性质、土壤微生物活性、产量和果实品质的影响。岩粉的掺入显著提高了堆肥中Ca、Mg、Fe、Mn、Zn、B、Al等微量元素的含量，但没有增加堆肥的植物毒性。通过生物生态板的群落水平生理分析表明，强化堆肥具有更高的微生物代谢活性和功能多样性。在质量较差的土壤中掺入两年的石粉堆肥使产量显著增加，2013年和2014年分别比未处理的对照增加120%和187%。施用石粉堆肥可显著提高成熟苹果树超氧化物歧化酶（SOD）活性和维生素C浓度。有益的影响与较高的微生物活性和土壤微生物组组成的变化相一致。我们的研究结果表明，将岩尘强化堆肥与氮磷钾肥料相结合的做法提供了一种经济有效的方式，为作物提供宏量和微量营养素，确保更好的营养生长和更高的产量。
ABSTRACT This study examined the effect of compost fortified with rock dust on the soil properties, soil microbial activity, and yield and fruit quality in a mature apple orchard from the Jiangsu province of China. The incorporation of rock dust significantly improved the microelement contents of Ca, Mg, Fe, Mn, Zn, B, and Al, but without increasing phytotoxicity of the compost. The fortified compost had higher metabolic activity and functional diversity of microorganisms as determined by the community-level physiological profiling with Biolog EcoPlates. The two-year incorporation of the rock dust compost into a poor-quality soil led to a significant increase in the yield with the increase of 120% and 187% compared to untreated control in 2013 and 2014, respectively. Application of the rock dust compost obviously promoted superoxide dismutase (SOD) activity and concentration of vitamin C in mature apple trees. The beneficial effects coincided with higher microbial activity and shifts in the composition of the soil microbiome. Our results demonstrate that the practice of combining the rock dust-fortified compost with NPK fertilizers provides a cost-effective way of supplying crops with macro-and micronutrients ensuring better vegetative growth and higher yields.
