Elite breeding method for tea-oil trees

Abstract

The invention discloses an elite breeding method for tea-oil trees. The elite breeding method comprises the following steps: drying harvested ripe tea-oil tree fruits in the shade for 2-3 days and selecting big and full seeds with the size of 380-440 grains per kilogram; taking out the seeds in March and April and sowing the seeds on a prepared sand bed surface, i.e. arraying the seeds on the sand bed surface one by one and not overlapping the seeds, wherein the thickness of a sand bed is 20cm-25cm; then paving sand with the thickness of 3cm-4cm on the seeds after sowing the seeds and covering the seeds; slightly pressing on the sand; watering for one time to be permeable; usually watering to guarantee that the seeds have enough water when germinating; when most bud seedlings are about to come up and do not expand leaves, taking out the bud seedlings to be used as stocks; selecting thick and solid spring tips without plant diseases and insect pests and with full buds and leaves of the current year on a good seed tree to graft; grafting from the middle ten days of May to the end of June; when one year seedlings grow, the height of the seedlings is more than 45cm and root systems are developed completely, transplanting in a planting large field. The elite breeding method for the tea-oil trees has the advantages of good quality, high yield, stable yield and strong resisting capability to the plant diseases and insect pests.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for breeding fine varieties of camellia oleifera. [0002] Background technique [0003] Camellia oleifera is the main economic forest tree in my country, which has the characteristics of strong adaptability, low operating cost, large profit and wide application. The oil extracted from camellia oleifera has a clear taste and rich nutrition. It is an excellent organic and green edible oil. By the majority of consumers like. [0004] In order to ensure the stable and high yield of the new Camellia oleifera forest after it enters the full fruit stage, it is the key technology to cultivate high-yielding and fine-bred Camellia oleifera seedlings, especially the effective use of local excellent resources, and the cultivation of excellent local varieties suitable for local climate, soil and other conditions is the key. There are many ways to grow Camellia oleife...

Problems solved by technology

There are many ways to grow Camellia oleifera seedlings. There are seed breeding, but the time is long, and the purity of the species is not high. There is cutting seedlings, but the deep roots are slow, and the excellent characters are not outstanding; there are direct grafting seedlings, but they have not been screened and optimized. Good fertility is not high

More importantly, the var
