Special base stock bag for oil-tea tree seedling cultivation and preparation method thereof

The invention relates to a special base stock bag for oil-tea tree seedling cultivation and a preparation method thereof. Base stock comprises northeast peat soil, slow release fertilizer, a powder type water-retaining agent, bark grains, saw dust, rice hulls, yellow-clay fine powder, vermiculite and perlite. The preparation method of the base stock bag includes steps of raw material preparation, single term processing, raw material mixing, base stock bagging, long bag cutting and the like. The base stock bag greatly improves survival rate of seedlings and shortens a seedling growing period, the slow release fertilizer achieves even fertilizing matching with seedling fertility required rhythm, the water-retaining agent guarantees a water demand of seedlings in a survival period, and the northeast peat soil balances breathing of seedling roots and water retaining. The materials are easy to obtain, and the special base stock bag is suitable for industrialized production of grating seedlings of oil-tea tree seedlings.
