A kind of root grafting propagation method of Camellia oleifera in autumn

Abstract

The present invention discloses an oil tea root grafting propagation method in autumn. The oil tea root grafting propagation method comprises the steps of young stock cultivation, grafting propagation and seedling management operation. The oil tea root grafting propagation method comprises the steps of using seedlings obtained from oil tea seed sand storage accelerating germination as stock seedlings, grafting collected semi-lignified or lignified oil tea cuttings to the cultivated oil tea stock seedlings, planting and cultivating the oil tea cuttings in a seedling growing container equipped with seedling growing substrate, and obtaining oil tea seedlings through seedling management after grafting. Oil tea seedling roots are used as stocks for grafting in autumn, utilization rate of the cuttings can be effectively increased, oil tea seeds are saved, survival rate is high, seedling quality is good, qualified seedling percentage is high, and grafting labor shortage is alleviated by seedling growing in batches, thereby facilitating labor dispersion. The oil tea root grafting propagation method has good economic, social and ecological benefits.

Description

technical field

[0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a propagation method of camellia oleifera, in particular to a root grafting propagation method of camellia oleifera in autumn. Background technique

[0002] Camellia ( Camellia spp.) is the most productive oil-use species in the Theaceae family Camellia. Camellia oleifera in a broad sense refers to the tree species with high seed oil content in Camellia plants and a certain cultivation area.
