Embodiment 1

[0026] The new method for cutting and breeding tea seedlings of the invention is to promote the cutting and breeding of tea seedlings by inoculating arbuscular mycorrhizal fungi. Include the following steps:

[0027] a. Separation of strains

[0028] The arbuscular mycorrhizal fungi were derived from the dominant species in the rhizosphere of tea trees. The tea tree rhizosphere soil was taken, and the dominant monospores of arbuscular mycorrhizal fungi were isolated by wet sieving-sucrose centrifugation.

[0029] b. Propagation of bacteria

[0030] Take yellow sand soil (need to pass through a 2mm sieve) and river sand in a ratio of 1:1, sterilize it by irradiation (12.5kGy60Co), and then plant white clover for propagation. The clover seeds are washed with 10% NaOH for 3-5 minutes, washed with distilled water several times, soaked in 75% alcohol for 20 minutes, washed with distilled water, dried and sown with water and air.

[0031] c. Seedbed preparation

[0032] The tea...

Abstract

The invention discloses a tea seedling mycorrhization cutting breeding new method. The tea seedling mycorrhization cutting breeding new method promotes tea seedling cutting breeding by inoculating arbuscular mycorrhizal fungi and comprises the following steps of separating arbuscular mycorrhizal fungi dominant monads; performing fungi propagation by planting whiter clover; preparing seedbeds; cutting branches in a short-scion cutting breeding method; inoculating the propagated mycorrhizal soil; performing tea garden management. By inoculating AMF (arbuscular mycorrhizal fungi), the tea seedling mycorrhization cutting breeding new method can promote tea seedling cutting breeding and growth of root systems of tea seedlings, improve the quality of bred tea seedlings, shorten the tea seedlingbreeding cycle, increase the economic benefits and achieve high significance to development of tea industry.

Description

technical field [0001] The invention relates to a new method for promoting the cutting propagation of tea seedlings by using arbuscular mycorrhizal fungi. Background technique [0002] Tea tree [Camellia sinensis (L.) O. Kuntze] belongs to the camellia species of the genus Camellia, is a perennial evergreen woody plant, and is one of the important economic crops in my country. At present, the area of ​​tea gardens in my country continues to increase, with an average annual increase of about 1.75 million mu, and there is still a large area of ​​old tea gardens being renovated. Therefore, there is a great demand for tea seedlings. The tea seedling propagation method that mainly adopts in the tea production at present is the cutting propagation method. This method was first used by Fujian tea farmers in the early 21st century. In the 1950s, tea workers in Fujian Province systematically studied and summarized the short-ear cutting propagation technology and promoted it througho...
