Embodiment 1

[0022] 1) Bacteria preparation:

[0023] a) Prepare a matrix with yellow sand and river sand at a ratio of 1:1 and sterilize it by irradiation (12kGy) for planting white clover to cultivate high-efficiency AMF strains.

[0024] b) Select the white clover with well-developed root system as the host, scrub the white clover seeds, soak them in 0.3% potassium permanganate solution for 3-4 hours, wash them with clean water, soak them in warm water at 20-30°C for 1 day, and drain them ;

[0025] c) the treated host seeds are applied to the matrix respectively with the AMF bacterial agent, and the water used during the cultivation is sterile water;

[0026] d) After 3-4 months of inoculant culture, remove the host plant, mix the substrate and granulate it for later use.

[0027] 2) Seedbed establishment:

[0028] a) The test site was selected at the Guiyang tea garden base of Guizhou Tea Research Institute, and tea trees were planted for a long time in the early stage of the test;...

Abstract

The invention discloses a method for improving the effect of mycorrhized cutting propagation of tea seedlings in the field. The method is to spread AMF high-efficiency bacterial strain Cystis root on the cutting seedbed in advance and spray strigolactone after the cutting Thereby improving the effect of mycorrhized cutting propagation of tea seedlings in the field. The test results show that using this method to breed tea seedlings can effectively improve the mycorrhizal cutting effect of tea seedlings in the field, increase the infection rate of tea seedlings by AMF, and increase the germination rate, callus emergence rate and survival rate of tea seedlings , promote the improvement of growth indicators such as stem height, root length, dry and fresh weight of tea seedlings, and also have outstanding advantages such as simple operation, low labor intensity, and small increase in investment, and are suitable for popularization and application in actual production.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for improving the effect of mycorrhized cutting propagation of tea seedlings in the field. Background technique [0002] Tea tree (Camellia sinensis (L.) O. Kuntze) belongs to the Camellia family Camellia, is a perennial evergreen woody plant, and is one of the important economic crops in my country. At present, my country's tea planting area continues to expand, with an annual increase of more than 50,000 hectares. The main breeding method of domestic tea trees is the cutting propagation method, that is, when cutting, select a 2.5-3cm semi-lignified short ear with a complete mature leaf and a full axillary bud. Mature and complete leaves are used for ear cuttings. Compared with the traditional sowing seedlings, this method has the advantages of retaining the excellent traits of the mother ear and facilitating the standardized production and management of tea gar...
