Purpose of Review

Continuous replanting of land with the same or similar plant species can result in the accumulation of harmful soil microbes, which can lead to crop failure. In this review, we explore the influence of constant replanting on the health of short-rotation forestry soil, focusing on the accumulation of deleterious microbes and the decline of beneficial microbes. We also suggest possible practical solutions to address this problem and consider future research that could be conducted to better understand and reduce the build-up of deleterious soil microbes in short-rotation forestry soil.

Recent Findings

Compelling evidence that continuous replanting of the same tree species in short-rotation plantation forestry might contribute to the build-up of deleterious soil microbes is still lacking. However, our assessment of existing soil microbiome data from global short-rotation plantation environments suggests a high risk of an accumulation of harmful microbes and a loss of beneficial microbes in plots that were continually replanted with the same tree species. Based on this evidence, and that from agriculture, we propose further research to acquire a better understanding of the build-up of harmful soil microbes in short-rotation plantation forestry, and suggest crop rotation and intercropping strategies to avoid this malady in the future.

Summary

The accumulation of microbes detrimental to plantation trees and the decline of microbes beneficial to these trees are realistic risks when plantations are continually replanted with the same tree species. Extensive research is necessary to evaluate the impact of short continuous planting rotations on the biodiversity of soil microbes in plantations and to develop strategies that would alleviate the build-up of detrimental microbes.

连续补植可能会降低短轮伐期人工林的土壤健康

审查目的

连续在土地上重新种植相同或相似的植物种类可能会导致有害土壤微生物的积累，从而导致农作物歉收。在这篇综述中，我们探讨了不断补植对短周期林业土壤健康的影响，重点关注有害微生物的积累和有益微生物的减少。我们还提出了解决这一问题的可行的实际解决方案，并考虑未来可以进行的研究，以更好地了解和减少短期林业土壤中有害土壤微生物的积累。

最近的发现

目前仍缺乏令人信服的证据表明，在短轮伐期人工林中连续重新种植相同树种可能会导致有害土壤微生物的积累。然而，我们对全球短周期种植园环境中现有土壤微生物组数据的评估表明，在不断重新种植相同树种的地块中，有害微生物积累和有益微生物丧失的风险很高。基于这些证据以及来自农业的证据，我们建议进行进一步的研究，以更好地了解短周期人工林中有害土壤微生物的积累，并提出作物轮作和间作策略，以避免未来出现这种弊病。

概括

当人工林不断重新种植相同树种时，对人工林有害微生物的积累和对这些树木有益的微生物的减少是现实的风险。有必要进行广泛的研究，以评估短期连续轮作对种植园土壤微生物生物多样性的影响，并制定减轻有害微生物积累的策略。
