Physical and chemical properties of several kinds of agriculture and forestry waste composite matrix and their effect on container seedling of Phoebe chekiangensis
Litter,drug waste,sawdust,pecan shells,and corn straw were mixed with perlite and vermiculite to form 10 mixed matrixes of different proportions.The physical and chemical properties of the different mixed matrixes were analyzed by comparison with the commonly used container seedling matrix(peat∶vermiculite∶perlite =3∶1∶1,the control).Results showed treatments 2,3,4,5 and 7 are more optimal.The more optimal matrix mixes were then used to determine growth indexes and physiological characteristics of three-year old Phoebe chekiangensis seedlings.Results showed height,basal diameter,branch number,shoot fresh and dry weights,root fresh and dry weights,soluble sugar content,and soluble protein content of seedlings of the treatment 3 (litter ∶ corn ∶ straw ∶ vermiculite ∶ perlite=3 ∶ 3 ∶ 2 ∶ 2) were better than the control matrix.The height-diameter ratio,root-shoot ratio,root activity,and chlorophyll content of the treatment 3 were not significantly different from the control matrix (P＞0.05).Price of trearment 3 is 89 yuan·m-3 which could save about 150.00 yuan· m-3 by comparison with the control.Thus,the control matrix with peat primarily can be replaced by the treatment 3 on planting in Ph.chekiangensis.It is of great significance to realize factory production of the Ph.chekiangensis container seedling.
