Abstract:

10 solutions of different concentration of N,P,K,Ca,Mg,S were used to culture the hedges in the experiment while the traditional hedges growing on soil is used as control. 8 indexes including cutting length, number of cutting burl, diameter of cutting, fresh mass of cutting, dry mass of cutting, index of fresh hydrophytic root, lignification degree of cutting, survival rate of cuttings have been measured and analyzed. 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.
