中文摘要:

为探究再生黑水（Reclaimed blackwater，RBW）在农业浇灌中对土壤质量和作物生长的影响，以苋菜、空心菜、白菜3种作物为试验对象，用经厌氧处理45 d的黑水进行浇灌，设置RBW（1 50%）、RBW（2 100%）为处理组，以CK（清水）作为对照开展试验。结果表明：与CK处理相比，经过RBW处理后，土壤综合肥力提升了1.85%~31.52%，且RBW₂处理组土壤肥力更高；土壤中细菌群落α-多样性指数未产生显著差异（P>0.05），且优势菌门种类（Proteobacteria、Chloroflexi、Actinobacteriota、Acidobacteriota）未改变；作物株高、根长、鲜质量、干质量和可溶性糖含量均有显著提高，RBW₂处理组结果优于RBW₁处理组，而维生素C（VC）含量下降了14.63%~62.36%，但均高于1 mg·g^-1，仍属于高VC含量作物。研究表明，采用RBW浇灌可提高土壤肥力、维持土壤微生物多样性以及促进作物生长。

英文摘要:

In order to investigate the effects of recycled blackwater（RBW）on soil quality and crop growth in agricultural irrigation, three types of crops, namely amaranth, water spinach, and bok choy, were irrigated with blackwater that was treated through 45-day anaerobic digestion. Two irrigation treatments were set：RBW₁（50%）and RBW₂（100%）, using CK（clean water）as the control. The results showed that, compared with the CK treatment, RBW treatments increased comprehensive soil fertility by 1.85%-31.52%, with RBW₂ exhibiting higher soil fertility. The soil α-diversity index of the soil bacterial community showed no significant differences（P>0.05）, and the dominant phyla（Proteobacteria, Chloroflexi, Actinobacteriota, Acidobacteriota） remained unchanged. Crop height, root length, fresh weight, dry weight, and soluble sugar content increased under RBW treatments, with RBW₂ outperforming RBW₁. Although vitamin C（VC） content decreased by 14.63%-62.36%, all values remained above 1 mg·g^-1, indicating that the crops still retained high VC levels. The results showed that the use of RBW as supplemental water can improve soil fertility, maintain microbial diversity and promote crop growth, which provides a scientific basis for exploring the safe and efficient resource utilization of recycled black water, and is in line with China ′s sustainable development strategy.
