Tea tree short sprout tender lateral branch cuttage

Abstract

The invention discloses a tea short-spike tender lateral branch cutting propagation method, comprising: the cultivation of spikes in mother tree orchard, establishing of nursery bed, cutting and seedling nursing. The cutting propagation method is characterized in that the spike cutting adopts the short-spike tender lateral branches. The cultivation method comprises the steps as follows: (1) more fertilizer is fertilized 10-15 days before spring tea; (2) after the spring tea is picked, the cutting is carried out immediately and foliar fertilizer which can prompt the growth of the buds is sprayed so as to prompt the buds to grow as mother spikes; (3) when the mother spikes grows with the depth of 30-50cm, the topping operation is carried out so as to prompt the lateral bud of the mother spikes to bourgeon; (4) when the lateral bud of the mother spike grows to become new tender lateral branches with the heights of 10-15cm, the spike cutting can be carried out. The tea short-spike tender lateral branch cutting propagation method has the advantages that under the condition of normal management, the survival rate reaches more than 95% and the seedling cutting rate reaches more than 90%; the seedling cutting time is short and requires only 6 months from cutting to seedling cutting, saves land renting expense and seedling nursing expense by more than 50% and improves the seedling cutting by more than 20%.

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 fringe cutting is that the new shoots are semi-lignified, the leaves are mature, and the axillary 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 form only surviving and c...

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
