目的生物孔隙为未耕土层中根系的生长提供了有利的化学、生物和物理性质。在那里，他们被认为是营养“热点”与优先根生长。然而，文献缺乏一个量化的代谢活动，由于主要作物的养分收购，而生长在biopore sheath.MethodsA盆栽实验进行映射根的代谢活动，如pH值的变化所示。春大麦（Hordeum vulcanum L.）春油菜和蚕豆（Vicia fabaL.）在蚯蚓（Lumbricus terrestrisL.）或主根（菊苣），与没有孔隙底土（散装土）相比。pH敏感的平面光电二极管，以图像的鞘的平面部分，同时保留一个完整的biopore sheath在experiment.ResultsRoots首先发现在视野中的蠕虫biopore然后根biopore和散装土壤。在第一次测量时，蠕虫生物孔鞘中的pH值最高（LS-均值±SEM：7.16a±0.11），其次是根生物孔鞘（6.99ab±0.12）和散装土壤（6.61b±0.12）。在春油菜中，随着时间的推移，在散装土壤中发现了显著的碱化（+0.80 Δ pH）。蚕豆根生物孔鞘显著酸化（-0.73 Δ pH）。春大麦没有表现出显着的pH值changes.ConclusionsThe目前的研究结果揭示了更快的根生长的趋势，通过biopores和较高的初始pH值的biopore鞘相比，散装土壤。生物孔隙不仅作为根的延伸路径，而且它们的鞘也为根在底土中的活动提供环境。
AimsBiopores offer favorable chemical, biological and physical properties for root growth in untilled soil layers. There they are considered as nutrient “hotspots” with preferential root growth. However, the literature lacks a quantification of metabolic activity due to nutrient acquisition of main crops while growing in the biopore sheath.MethodsA pot experiment was performed to map the metabolic activity of roots, as indicated by pH change. The roots of spring barley (Hordeum vulgareL.), spring oilseed rape (Brassica napusL.) and faba bean (Vicia fabaL.) were growing through the biopore sheath influenced by an earthworm (Lumbricus terrestrisL.) or a taproot (Cichorium intybusL.), in comparison to subsoil without a pore (bulk soil). pH sensitive planar optodes were applied in order to image a planar section of the sheath, while preserving an intact biopore sheath during the experiment.ResultsRoots were first found in the field of view in worm biopore then root biopore and bulk soil. At time of the first measurement the pH value was highest in worm biopore sheath (LS-Mean±SEM: 7.16a±0.11), followed by root biopore sheath (6.99ab±0.12) and bulk soil (6.61b±0.12). In spring oilseed rape a significant alkalization (+0.80 Δ pH) was found over time in bulk soil. Faba bean significantly acidified the root biopore sheath (-0.73 Δ pH). Spring barley showed no significant pH changes.ConclusionsThe results of the current study reveal a trend of faster root growth through biopores and a higher initial pH value in the biopore sheaths compared to the bulk soil. Biopores serve not only as an elongation path for roots, but their sheaths also provide an environment for root activity in the subsoil.
