Camellia oleifera seedling radicle grafting method

Abstract

The invention discloses a camellia oleifera seedling radicle grafting method which comprises the steps of camellia oleifera seed screening and sowing, nursery land selection and preparation, nutrient soil and container preparation, grafted scion collection and treatment, determination of proper grafting time, treatment of rootstock seedlings, radicle cutting, radicle grafting and container seedling management. Compared with the prior art, the method has the greatest difference that the radicles of camellia oleifera rootstock seedlings are used as grafting points and are subjected to multi-section cutting to obtain multi-section standard rootstocks, the number and quality of the grafted rootstocks are improved, the grafting cost is reduced, the standard rootstock seedlings are soaked in a plant growth regulator, the activity of peroxidase (POD) and polyphenol oxidase (PPO) is improved, callus formation is promoted. elongation growth of roots and branching are facilitated, and the survival rate of grafted seedlings is increased. The camellia oleifera seedling radicle grafting method has the advantages of being low in cost, high in grafting success rate, free of sprouts, high in improved variety purity, high in survival rate, convenient to construct and operate, capable of saving manpower and material resources and the like.

Description

technical field [0001] The invention belongs to the technical field of growing seedlings of economic trees, and in particular relates to a method for grafting radicles of camellia oleifera seedlings. Background technique [0002] Camellia oleifera, aliases: tea seed number, camellia oil tree, white flower tea; Camellia oleifera belongs to Theaceae, evergreen small tree. It is named because its seeds can be squeezed for oil. Camellia oil is a high-quality edible oil with clear taste and fragrance, rich nutrition and storage resistance. Tea cake is both a pesticide and a fertilizer, which can improve the water storage capacity of the farmland and prevent pests in the rice field. The fruit shell is the raw material for extracting roasted gum and activated carbon. [0003] Anhui is one of the areas suitable for the cultivation of camellia oleifera. By the end of 2019, the cultivation area of ​​camellia oleifera in Anhui has reached 3 million mu, surpassing chestnut and tea, an...

Problems solved by technology

[0009] In the prior art, the grafting method of Camellia oleifera mostly adopts the hypocotyl grafting method. In this process, the stems of the stock seedlings are cut, and the cut spikes are inserted into the cuts of the stems of the stock seedlings, squeezed and folded with a thin aluminum sheet, and then folded. The grafted container seedlings are planted in a special matrix container, and cultivated under certain conditions for more than 17-22 months to be out of the nursery for afforestation; the defect of the prior art: because the container grafted seedlings are in the cultivation process, the stems are easy to grow branches , although it is manually removed, it is easy to germinate repeatedly; if the germinated branches are not removed, a large number of seedlings will be formed; this will bring trouble to the management of the later stage of grafting, and a large amount of manual removal is required; in practice, it has been found that even a forest tree has a small amount of seedlings. germination branch; secondly, the hypocotyl stem is dry and brittle, and it is easy to crack when cutting the ear, which reduces the success rate of grafting
