Study On Industrialized Breeding Substrate Formula Of Main Plantation Tree Species In Ningbo

For selecting the suited formula of container seedling and providing the reference of cultivating good quality seedling, the effects of different substrates (constituent:peat soil, perlite, husks, wood chips, animal manure and compound fertilizer) on one-year and two-years old container seedlings of 7 plantation trees species applied generally in Ningbo(Pinus elliottii, Cyclobalanopsis glauca, Castanopsis sclerophylla,Schima superba,Myrica rubra,Photinia×frasery,Sepindus mukorossi) were studied.10 types of substrate formulas were tested by one-year old seedling (Al as CK) and 7 types tested by two-years old seedling (B1 as CK). A single treatment had 3 repeats and a repeat used 30 seedlings. Height and ground diameter were measured periodically.Results of substrate formulas to showed different between seedling age and tree species. To one-year age seedlings of Pinus elliottii, A3 treatment was the optimal substrate formula, A2 and A4 comparatively suitable, A1 (CK), A5 and A10 basically suitable; to one-year age seedlings of Cyclobalanopsis glauca, A1 (CK) treatment was the optimal substrate formula, A4 comparatively suitable, A2 and A3 basically suitable to one-year age seedlings of Castanopsis sclerophylla, A2 and A3 treatments were the optimal substrate formulas, A1 (CK) comparatively suitable, A4 and A5 basically suitable; to one-year age seedlings of Schima superba, A2 and A3 treatments were the optimal substrate formulas, A1 (CK) comparatively suitable, A5 basically suitable; to one-year age seedlings of Myrica rubra, A2 and A3 treatments were the optimal substrate formulas, A1 (CK) comparatively suitable, A4 basically suitable; to one-year age seedlings of Photiniaxfrasery, A2 and A3 treatments were the comparatively suitable formulas.As a whole, A2 and A3 substrate formulas were better.To two-years age seedlings of Pinus elliottii, B3 and B7 treatment were the optimal substrate formulas, B1 (CK) comparatively suitable, B4,B5 and B6 basically suitable; to two-years age seedlings of Castanopsis sclerophylla, B3 treatment was the optimal substrate formula, B2 comparatively suitable, B1(CK) and B7 basically suitable; to two-years age seedlings of Schima superba, B5 and B7 treatments were the optimal substrate formulas, B3 comparatively suitable, B1 (CK), B2, B4,B6 basically suitable; to two-years age seedlings of Myrica rubra, B3 treatments were the optimal substrate formulas, B5 comparatively suitable, B1 (CK), B4, B7 basically suitable; to two-years age seedlings of Sepindus mukorossi, B3 and B4 treatments were the comparatively suitable formulas, B2 comparatively suitable, B1 (CK) and F basically suitable.As a whole, B3 substrate formula was better.
