利用草炭对葡萄根区进行改良,比较研究了传统混合和局部改土方式对葡萄根系形态、生物量、冠根比、根系活力和根系激素状况的影响。结果表明:草炭可有效提高根系干物重、根系活力以及根系Zip、IAA和GA的含量,降低根系ABA含量。不同改土模式对葡萄根系的影响不同,局部改土一定程度提高根系干重和根系活力,并有效促进了地上和根系的平衡生长。 Grape root zone was modified by using peat, and the effect of traditional mixing and local soil amendment on root morphology, biomass, crown-root ratio, root activity and root hormone of grape was studied. The results showed that: peat can effectively increase root dry weight, root activity and root Zip, IAA and GA content, reduce root ABA content. Different soil amendments have different effects on the root system of grapevines. Local soil improvement can increase the root system dry weight and root vigor to some extent and effectively promote the balanced growth of the aboveground and root systems.
