Oil tea high cut crown change combined grafting method

Abstract

The invention discloses an oil tea high cut crown change combined grafting method. The method includes the following steps that 1, 4 or more oil tea fine varieties are selected for manufacturing scions; 2, a stock with 4 or more main branches is selected; 3, the different fine varieties are grafted on the different main branches in a round matched mode; 4, maintenance is carried out after grafting is completed. The 4 or more different fine varieties are grafted on the different main branches in the round matched mode on an old oil tea tree, the problem that the fruiting rate is low due to oil tea single-plant pollination is solved, and the high and stable yield of oil tea is increased; a grafting healing surface is large through section splitting, the grafting survival rate is high, and a section rapidly heals after spring twigs draw out. The intervals between the scions ranges from 2 cm to 3 cm, and the stock section at the grafting position heals rapidly, and is not likely to dry up to form half flourishing.

Description

Technical field [0001] The invention relates to the technical field of tea oil tree planting, in particular to a method for grafting a camellia oleifera high-cut crown combination. Background technique [0002] Camellia oleifera is an evergreen and long-lived tree species. It is planted once and has a harvest period of more than a hundred years. Generally, it can be closed into forests 8-10 years after planting. It can increase oil sources and increase forest coverage. It has beautification of the environment, It has the ecological functions of maintaining water and soil, conserving water sources, and regulating the climate. At the same time, it is a tree species with strong anti-pollution ability, strong resistance to sulfur dioxide, and strong resistance to hydrogen and chlorine. The Party Central Committee and the State Council have made major decisions on the strategic level of ensuring the safety of our country’s grain and oil and promoting farmers’ incomes to become rich. ...
