Problems solved by technology

[0003] However, Gardenia jasminoides has been planted by seeds for a long time. After a long period of selection, farm species suitable for local planting have been screened out from all over the country. Most of them are propagated by seeds, but the traits of the offspring are separated, and the yield of different plants varies greatly.
[0004] With the advancement of science and technology, the improvement of cultivation technology, and the improvement of propagation methods, people use cuttings for asexual reproduction, which ensures the stability of the species, but the survival rate of conventional cutting propagation is low, the utilization rate of cuttings is low, and the produced Seedlings cannot meet the needs of production

Embodiment 1

[0043] A method for improving the survival rate of gardenia jasmine cutting seedlings, comprising the following steps:

[0044] (1) Seedbed selection and preparation: Choose a plastic greenhouse with an irrigation system and fertile and loose soil. Spray the soil twice with 50% wettable powder thiophanate 200 times solution one month before the seedbed, and add a small amount of quicklime each time. Carry out soil disinfection, plow the soil deeply, and the interval between two times is one week; half a month before the cutting, apply 500 kg of organic fertilizer per mu to fertilize, so that the fertilizer is evenly distributed in the soil layer;

[0045](2) Seedbed treatment: The seedbed width is 1.2m, and peat soil is applied on the seedbed according to the ratio of garden soil to peat soil at a ratio of 8:2, and mixed evenly to make a flat seedbed with a height of 40cm, and then apply 1cm on the top. thick peaty soil;

[0046] (3) Cutting time: mid-March when the temperatu...

Abstract

The invention relates to a method for increasing the survival rate of seedling raising of yellow gardenia cuttings. The method comprises the following steps of (1) selection and preparation of a seedbed; (2) treatment of the seedbed; (3) determination of cutting time; (4) selection of a mother tree and scion collection; (5) scion treatment; (6) implementation of cuttage; (7) management after cuttage; (8) prevention and control of diseases and pests; (9) harvesting. By adopting the method, the cuttage survival rate and harvesting rate of yellow gardenia and the plantlet yield are increased significantly, the plantlet quality is obviously improved, and an obvious practical effect is obtained, wherein the cuttage survival rate of yellow gardenia plantlets is increased to 95% or above and increased by 5% or above in comparison with the highest cuttage survival rate of 90% in China at present.

Description

technical field [0001] The invention relates to the field of plant planting and cultivation, in particular to a method for improving the survival rate of Fenguan No. 1 gardenia jasmine cutting seedlings. Background technique [0002] Yellow gardenia, also known as gardenia, is an evergreen shrub of Rubiaceae. Gardenia contains a large amount of pigments, mainly yellow pigments and gardenia blue pigments, which are natural and high-quality raw materials for extracting food pigments. The pigments are bright in color, have no side effects, and have high nutrient content. Japan needs to import more than 20 tons of gardenia pigments from China every year, and the demand for gardenia pigments abroad continues to expand. There are 12 provinces in the south-central part of my country where it is traditionally planted, and it is used as traditional Chinese medicine in China. In order to meet the demand of domestic and foreign markets for the quality and quantity of the natural colo...
