The purpose of the study was to evaluate the soil-allelopathic activity in different soils under asparagus cultivation, while focusing on expression of injury by continuous cropping with the same cultivar. Moreover, this study was elucidated adsorption duration of activated carbon, which can easily absorb allelochemicals present in the soil, while associated with changes in the soil microflora. As a result, the effect of and degree of soil-allelopathic activity by application of activated carbon differs depending on the soil properties. When the application became collateral for the increase in soil microorganisms phase, the effect of adsorption duration of activated carbon would be sustained by desorption action of allelochemicals adsorbed to the activated carbon with the activity of soil microorganisms.

本研究的目的是评价芦笋在不同土壤栽培条件下的化感作用，同时重点研究同一品种连作对芦笋的伤害表达。此外，本研究还阐明了活性炭对土壤中化感物质的吸附时间长短，其吸附时间长短与土壤菌群的变化有关。因此，施用活性炭对土壤化感作用的效果和程度随土壤性质的不同而不同。当施用成为土壤微生物阶段增加的副品时，活性炭吸附的化感物质会随着土壤微生物的活性而解吸，从而维持活性炭吸附时间的效果。
