试验结果表明，陕西种源香椿硬枝插条在温室进行芽菜培育休眠芽萌发的最低温度指标为１６．８℃，有效积温３９．６℃；培养液：（ＮＨ４）２ＳＯ４０．６ｇ／Ｌ＋（ＮＨ４）Ｈ２ＰＯ４０．４５ｇ／Ｌ＋ＫＨ２ＰＯ４１．１ｇ／Ｌ＋ＣａＳＯ４０．６ｇ／Ｌ＋ＭｇＳＯ４０．５ｇ／Ｌ，其效果较其它溶液为好。
The results showed that the minimum temperature index of germination of dormant buds of Toona sinensis hardwood cuttings grown in greenhouse was 16.8 ℃ and the effective accumulated temperature was 39.6 ℃. The medium of (NH4) 2SO40.6g / L + NH4) H2PO40.45g / L + KH2PO41.1g / L + CaSO40.6g / L + MgSO40.5g / L, the effect is better than other solutions.
