Embodiment 1

[0022] A method for efficiently breeding Camellia oleifera seedlings in high altitude areas, comprising the following steps.

[0023] (1) Seedbed arrangement: Choose a simple greenhouse, level the soil in the greenhouse with tools, remove weeds, open 4 compartments, each compartment is 1.4-1.5m wide, and lay 10cm thick yellow on each compartment. Sandy soil, then lay 3cm thick perlite to form a seedbed, spray 0.1% potassium permanganate aqueous solution on the seedbed, cover the soil with black film and compact it after the soil is wet, and let it sit in the greenhouse for 10-15 days. Before cutting, use a branch to break the black film and leave a place for cutting. Insert 50 holes in each row, and insert a row every 4-5cm. The yellow loam soil used for cuttings must be core soil, acidic or slightly acidic soil with a pH of 5.0-6.5.

[0024] (2) Rooting agent configuration: Use ABT rooting powder, willow extract, potassium dihydrogen phosphate, potassium nitrate, and ammoni...

Abstract

The invention particularly relates to a method for efficient cuttage breeding of camellia oleifera seedlings in a high altitude area. The method comprises the steps of seedbed preparation, rooting agent preparation, cutting slip treatment, cuttage, film mulching, cutting slip management, bagging culture, acclimatization and transplantation and the like. The upper layer of a matrix used for cuttage is perlite, a rooting agent used for cuttage is prepared from ABT rooting powder, a willow extracting solution, monopotassium phosphate, potassium nitrate and ammonium nitrate in proportion, rooting hormones and mineral nutrition contained in the rooting agent can meet the requirements of camellia oleifera for rooting and growth, formation of adventitious roots and lateral roots of cutting slips is promoted, and good growth of the cutting slips is ensured. After cutting is completed, the seedbed is covered with a white plastic film, so that the temperature and humidity of the seedbed are increased, and good temperature and humidity conditions are provided for rooting of the cutting slips. In addition, after rooting of the cutting slips, the cutting slips are transplanted into a degradable nutrition bag to be cultured for a period of time, and the survival rate and stress resistance of the camellia oleifera seedlings are greatly increased through transplanting of the nutrition bag. The method can meet the requirement for producing the camellia oleifera seedlings in high-altitude areas.

Description

technical field [0001] The invention introduces a method for high-efficiency cutting and rapid propagation of camellia oleifera seedlings in high-altitude areas, and relates to the field of seedling propagation in the agricultural field. Background technique [0002] Camellia oleirera (Camellia oleirera Abel) is a unique woody oil tree species in my country. Its tea seed oil is rich in unsaturated fatty acids, clear in color, fragrant in taste, rich in nutrition, and durable in storage. In addition, waste materials such as tea cakes and tea shells can also be used to extract industrial raw materials such as tea saponin and tea polysaccharides, which can be used as organic fertilizers and biological pesticides. With the continuous improvement of people's awareness of the economic value of Camellia oleifera and the promulgation of the "National Camellia oleifera Industry Development Plan (2009-2020)", there has been a boom in Camellia oleifera planting in many places across th...
