The invention discloses a
tea tree cross-breeding method. The
tea tree cross-breeding method comprises a growth age and a bearing age and comprises the following steps of 1, parent selection, 2, planting, 3,
pruning, 4,
fertilizer applying, 5,
greenhouse building, 6,
pollination, 7,
branch and leaf
thinning, 8, seed harvesting, and 9, seeding. The
tea tree cross-breeding method disclosed by the invention has the advantages that clear parental origins of
hybrid seeds of
offspring is guaranteed by using self-incompatibility of a parent, and the parental origins of the
hybrid seeds of the
offspring are also easy to distinguish. The tea tree cross-breeding method disclosed by the invention has the advantages that distances between plants is large; and problems such as close growing, crossing and overlapping of tree crown branches, poor ventilation and
light transmission, breeding of pests and diseases, easily aged branches and less fruits can be effectively solved. The tea tree cross-breeding method disclosed by the invention can persistently obtain
hybrid offspring with consistent properties, can provide a stable cultivation method for cultivation and screening works of tea tree plants and is very suitable for scientific researches and large-scale tea tree
plant seedling breeding.
