Rapid propagation method applicable to golden camellia in mountainous areas

Abstract

The invention discloses a rapid breeding method suitable for Camellia camellia in mountainous areas, comprising: S1, treatment of Camellia camellia mother tree: selecting side branches on the mother camellia camellia tree and peeling them circularly; S2, preparing large cuttage stems: cutting and girdling treatment After the side branch, the top is sealed with wax, and the girdling mouth on the side branch is soaked in indole acetic acid solution to obtain a large cuttage; S3, making the rooting matrix: S4, rooting treatment in the cutting box: the rooting matrix in S3 and the cuttings obtained in S2 Put the large poles into the cutting box for root-promoting treatment to obtain cutting seedlings; S5, transplanting and post-processing: after the root system of the cutting seedlings grows to 3cm, take the cutting seedlings out of the cutting box and move them to the hillside for planting. The present invention adopts large poles for cuttings, uses a cutting box to accelerate root growth, and develops the root system, so as to improve the rooting rate and transplanting survival rate of camellia camellia, and realize the efficient breeding of camellia camellia.

Description

technical field [0001] The invention relates to the technical field of camellia japonica planting, in particular to a rapid breeding method for camellia japonica in mountainous areas. Background technique [0002] Camellia japonica is an evergreen shrub or small tree, 2-6m high, with off-white, smooth bark, alternate leaves, broadly lanceolate to oblong. Flowers solitary in leaf axils or near terminal, golden yellow, cup-shaped, pot-shaped or bowl-shaped when open, 3-3.5cm in diameter; 9-11 petals, broadly ovate to obovate or oblong, fleshy, with Waxy luster; flowering period from November to next March. Capsule triangular oblate, yellow-green or purple-brown. Cuttings are a common method of propagation for growing plants. The stems, leaves, roots, buds, etc. of some plants can be cut off (called cuttings in gardening), or inserted into the soil, sand, or soaked in water, and can be planted after rooting to make it an independent new plant . In agricultural and forestry...

Problems solved by technology

The traditional cutting method mostly uses red heart soil as the propagation substrate for cuttings, because the red heart soil is compacted and waterlogged, during the production management process, if the amount of water sprayed is too much, the cuttings of Camellia japonica inserted in the substrate will rot and the seedlings will die; However, if the amount of water sprayed is too small, the cuttings of Camellia chrysalis will not be able to keep their freshness, and the seedlings will die because the leaves and branches are dry; The defects of traditional golden camellia cutting propagation only have a survival rate of 20-30%.

[0004] Especially in the process of planting camellia camellia in mountainous areas, traditional cutting seedlings are propagated with twigs. After growing to a transplanting height of about 30cm, the diameter is still only about 0.3cm, which makes transplanting in mountainous areas very easy. The death of transplanted seedlings caused by external environmental interference, such as strong wind, heavy rain, animal activities and other factors
