The difference between solution hedges and soil hedges is significant. The content of nutrition irons effects cuttings quality and rooting percentages directly. The lignification degree is negatively correlated with diameter of cutting, cutting length, number of cutting burl, fresh mass and dry mass, while the survival rate of cuttings is positively correlated to lignification degree and index of fresh hydropuytic root. Among all solutions No.5, No.6, No.8 have good affection for hedges culture, their cuttings are usually have suitable diameter and length, and high rooting percentages. No.6 is the best solution.展开更多
