Method for culturing camellia azalea nursery-grown plants by taking camellia japonica as rootstock

Abstract

The invention relates to a method for culturing camellia azalea nursery-grown plants by taking camellia japonica as rootstock. The method comprises the following steps: selecting main stems or twigs of the camellia japonica with the diameter of 2cm to 5cm as grafted branches; lopping the grafted branches with a saw, and cleaning and planing saw cuts with a grafting knife; selecting scions from camellia azalea trees; shearing the scions into minor segments in a manner of guaranteeing that each segment has 1 to 3 lateral buds, and grafting the scions; covering the saw cuts with moisture preserving films so as to prevent moisture transpiration loss; removing the moisture preserving films, and removing binding tapes after grafted scions survive; erasing new buds germinated from the camellia japonica rootstock; after the grafted scions are subjected to shooting, gradually increasing lighting and leaf surface moisture preserving, carrying out careful maintenance for one month, and then, carrying out conventional watering, fertilizing, deinsectization and disease prevention management; and carrying out nutritional fertilizer applying once every 20 to 30 days in a growing season, wherein a nutritional fertilizer is a mixture of 80-90 parts by mass of well-rotted farmyard manure and 10-20 parts by mass of bio-organic fertilizer, and the bio-organic fertilizer is prepared through mixing a botanical organic fertilizer and starch with bacillus subtilis and carrying out stacking for 30 days or more.

Description

technical field

[0001] The invention relates to the technical field of ornamental flower and tree cultivation, in particular to a method for cultivating Sijihong camellia seedlings by using camellia as rootstock. Background technique

[0002] Four Seasons Red Camellia is also known as Rhododendron Red Camellia. The flower is very similar to Rhododendron, but the essence is a camellia, hence the name. It blooms all year round. The flowers are bright red or pink, with 5-9 petals and no pedicels. The flowers open gradually from bottom to top on the branches, and the whole plant forms a continuous flowering phenomenon. The plant type and leaf shape characteristics of Rhododendron camellia also determine that Rhododendron red camellia has good development prospects in garden trees, hedgerows, bonsai and cut flowers.

[0003] Four Seasons Red Camellia is one of the oldest varieties of camellia, and the number of wild plants in the world is only nearly a thousand. Due to the lack...
