Problems solved by technology

In the grafting production of camellia oleifera, due to the influence of factors such as the quality of bud strips and rootstocks, weather during grafting, cultivation management measures, and environmental conditions for grafted seedling care, grafted seedlings germinated unstable and took a long time to germinate
According to statistics 6 months after grafting, the proportion of grafted seedlings surviving but not sprouting is about 9.5% on average, and about 15.8% of grafted seedlings grafted on the embryo anvil are not sprouting. The germination rate can reach more than 25%, and the non-germination rate of grafted seedlings exceeds 30%. The long germination period leads to poor uniformity of seedlings and increases the cost of care, and the non-germination of grafted seedlings leads to a decrease in the rate of nursery emergence
The method of using hormone treatment to promote the germination of grafted seedlings has been studied on fruit trees and other economic crops: the high-efficiency Huazhibao developed by Luoyang Forestry Institute is reported to be used on grafted fruit tree seedlings to achieve better germination effects. The test was used on grafted seedlings of Camellia oleifera germ seedlings and small seedlings grafted 3 months after grafting, which can achieve certain effects but will cause phytotoxicity; research on the promotion of germination of rubber tree seedlings, Huang Shoufeng and others affirmed that cytokinin The effect of treating bud strips on promoting the germination of bud grafted seedlings also gave a formula with 6-BA as the main active ingredient. Zhang Neng et al. used TDZ as the main active ingredient and used 6-BA, NAA and other ingredients in combination to obtain relatively good results. Good germination promotion effect, this method is used on Camellia oleifera grafted seedlings and small seedlings grafted seedlings, and can achieve certain results, but it is still not ideal

Embodiment 1

[0019] Embodiment 1, the application of germination promoting technology on the grafted seedlings of seedling stock:

[0020] 1. Pretreatment of cuttings: fertilize the multiplication nursery on October 10, 2012, apply water and fertilizer made of organic fertilizer once, and spray 1500 times of amino acid liquid fertilizer + 2000 times of 0.1% s-induced antibiotic + compound nitrophenol on the leaves Sodium 2000 times solution once. On October 20, 2012, the spikes were topped.

[0021] 2. Selection of rootstock and scion: The rootstock seedlings were planted on March 12, 2012, and observed on October 20, 2012. The seedlings had stable leaves and no pests and diseases. The diameter of the stem at a distance of 3 to 5 cm from the ground was measured to be 0.35 cm. Grafting on October 28, 2012, select the cuttings with branch age less than 1 year, aging leaf canopy, green and shiny leaves, and no pests and mites, and remove the axillary buds of a small round leaf at the bottom ...

Embodiment 2

[0026] Embodiment 2, the application of this method on the grafted seedling of camellia oleifera germ seedling stock:

[0027] 1. Pretreatment of cuttings: On April 5, 2013, the water and fertilizer made of organic fertilizer was applied once in the multiplication garden, and the leaves were sprayed with 1500 times of amino acid liquid fertilizer + 2000 times of 0.1% s-induced antibiotic + sodium nitrophenolate 2000 times Double liquid once. Spike topping on April 15, 2013.

[0028] 2. Selection of rootstock and scion: grafted on April 23, 2013. For the rootstock, choose the embryo seedlings that have just broken through the sand surface, grow vigorously, have no pests and diseases, and have seeds; for the scions, choose branches that are less than 1 year old, have aging leaves, green and shiny leaves, and no pests and mites. The axillary buds of a small round leaf at the bottom are removed, and the plump and strong leaf buds are selected as scions.

[0029] 3. Use hormones...

Abstract

The invention discloses a grafted camellia oleifera seedling accelerating method. The grafted camellia oleifera seedling accelerating method comprises scion preprocessing, stock and scion selection, scion hormone treatment, grafted seedling fertilizer supplementation, un-sprouted seedling hormone treatment and strong seedling cultivation. The grafted camellia oleifera seedling accelerating method is simple in process, low in production cost, beneficial to union of grafting incisions, free from harmful effects on seedling growth, high in sprouting promotion effects and stable in field performance. According to the grafted camellia oleifera seedling accelerating method, rapidly dipping scions inside combined hormones and transplanting and utilizing the combined hormones to spray un-sprouted seedlings are taken as the core and matched with planting management measures such as nutrition supplementation and bud picking, so that the problem of sprouting slowness and non-uniformity of the grafted camellia oleifera seedlings. The grafted camellia oleifera seedling accelerating method is applicable to production common grafted camellia oleifera seedlings and plantlets.

Description

technical field [0001] The invention relates to a method for promoting germination of grafted seedlings of camellia oleifera, belonging to the fields of crop cultivation, physiology and biochemistry. Background technique [0002] Camellia oleifera seedling grafting and seedling grafting are the main technical means used in the breeding of Camellia oleifera seedlings. In the grafting production of Camellia oleifera, due to the influence of factors such as the quality of bud strips and rootstocks, weather during grafting, cultivation management measures, and environmental conditions for grafted seedling care, grafted seedlings germinate unstable and take a long time to germinate. According to statistics 6 months after grafting, the proportion of grafted seedlings surviving but not sprouting is about 9.5% on average, and about 15.8% of grafted seedlings grafted on the embryo anvil are not sprouting.
