Problems solved by technology

At present, the vegetative propagation of tea trees usually adopts the technology of tea tree short ear core soil cuttings (or centerless soil short ear cuttings). The production cycle is at least one year, and the cycle is long. The survival rate of cutting seedlings is greatly affected by climate. High cost, labor and time consuming
At the same time, in the process of site preparation in the nursery, it is necessary to turn the soil and use soil disinfectants, which seriously damages the vegetation on the surface during the production process, easily causing soil erosion and environmental pollution

Embodiment Construction

[0026] 1. Prepare rooting medium for cuttings

[0027] Specific formula of cutting rooting culture medium: each liter of culture medium contains NH 4 NO 3 (825mg·L -1 ), KNO 3 (950mg·L -1 ), CaCl 2 2H 2 O (220mg·L -1 ), KH 2 PO 4 (85mg·L -1 ), MgSO 4 ·7H 2 O (185mg·L -1 ), MnSO 4 4H 2 O (22.3mg·L -1 ), ZnSO 4 4H 2 O (8.6 mg·L -1 ),H 3 BO 3 (6.2mg·L -1 ), KI (0.83mg·L -1 ),Na 2 MoO 4 2H2O (0.25 mg L -1 ), CuSO 4 ·5H 2 O (0.025mg·L -1 ), CoCl 2 ·6H 2 O (0.025mg·L -1 ),Na 2 EDTA (37.25mg·L -1 ), FeSO 4 ·7H 2 O (27.85mg·L -1 ), Al 2 (SO 4 ) 3 (10.8mg·L -1 ).

[0028] 2. Prepare growth hormone soaking solution

[0029] Dissolve α-naphthaleneacetic acid (NAA) with a small amount of 95% alcohol, and then dilute to a concentration of 1mg L with distilled water -1 , stored in a 4°C refrigerator until use. Before root soaking of cuttings, according to NAA 100mg·L -1 Growth hormone concentration, add 0.4mg·L -1 Thiamine Hydrochloride (Vitamin ...

Abstract

The invention discloses an asexual rapid propagation method which includes selecting and clipping cut spikes, immersing the cut spikes through hormone culture solution and root taking culture solution, temporary planting the cut spikes in nutrient soil for culture, finally conducting hardening-seedling on the cut spikes to obtain tea seedlings capable of being transplanted. The root taking culture solution is composed of various macroelements and microelements. Rooting rate of the cut spikes immersed by the culture solution reaches high to over 85%. The quick propagation method is short in seedling raising period, high in survival rate, capable of being used for repeated production and suitable for large-scale production.

Description

technical field [0001] The invention relates to crop cultivation technology, in particular to a method for asexual rapid propagation of tea trees and a rooting culture solution used in the method. Background technique [0002] Huangshan white tea (Camellia sinensis L.) is a variant of the Huangshan tea group, and it is a tea tree strain widely planted in and around Shexian County, Huangshan City, Anhui Province. At present, the vegetative propagation of tea trees usually adopts the technology of tea tree short ear core soil cuttings (or centerless soil short ear cuttings). The production cycle is at least one year, and the cycle is long. The survival rate of cutting seedlings is greatly affected by climate. The cost is high, labor and time-consuming. At the same time, in the process of site preparation for nurseries, it is necessary to turn the soil and use soil disinfectants, which seriously damages the surface vegetation during the production process, easily causing soil ...
