Tea tree short sprout tender lateral branch cuttage

Abstract

The invention discloses a cuttage breeding method of tea short sprout and lateral shoot, which comprises cultivation of cutting tea in a cutting tea garden, establishment of a seed bed, cuttage and seedling protection and is characterized in that: the short sprout and lateral shoot are adopted in cutting. The steps of the breeding method are that: (1) heavy subsoil is applied 10-15 days before picking spring tea; (2) after picking spring tea, pruning is processed at once and promoting fertilizer for leaf surface is sprayed, and then axillary bud grows to be the tea cutting; (3) when the tea cutting grows up to 30-50cm and terminal leaf bud still grows, top pruning is processed to promote lateral bud of the tea cutting to sprout; (4) when the lateral shoot on the tea cutting grows up to 10-15cm, cutting and cuttage can be processed. The method has the advantages that: in normal management condition, survival rate reaches more than 95 percent and nursery rate is up to more than 90 percent; nursery time is short and only 6 months are required from cuttage to the nursery; compared with the prior art, 50 percent of leased charge on land and protection fee of seedlings can be saved while the nursery rate is increased by over 20 percent.

Description

Technical field: [0001] The invention relates to a cutting propagation technique, in particular to a cutting propagation method of tea trees with short spikes and young lateral branches. Background technique: [0002] At present, the cutting propagation technology of improved tea tree varieties in China is to adopt short ear cuttings with one bud, one leaf, and a semi-lignified internode of 2.5 to 3 cm. The standard for ear cutting is that the new shoots are semi-lignified, the leaves are mature, and the ear cuttings are cut when the liquid buds are enlarged. The disadvantages of this breeding method are: (1) Due to the differences in the axillary buds of the tea tree spikes, generally the upper axillary buds expand faster, and the seedlings grow faster when cutting, followed by the middle axillary buds, and the lower axillary buds are the slowest. Swelling, some can grow new shoots after cuttings, some can't grow, even if they grow, they are very weak, and it is easier to ...

Problems solved by technology

The disadvantages of this breeding method are: (1) Due to the differences in the axillary buds of the spikes of tea trees, generally the upper axillary buds expand faster, and the seedlings grow faster when cutting, followed by the middle axillary buds, and the lower axillary buds are the slowest. Swelling, some can grow new shoots after cuttings, some can't grow, even if they grow, they are very weak, and it is easier to form only surviving and cannot emerge from the nursery. The proportion of small seedlings is large, so the rate of emergence from the nursery is not high. About 50-70%; (2) It takes a long time to go out of the nursery, about a year or so, and it takes a lot of labor and high cost
