Accelerant facilitating plant cutting rooting

Abstract

The invention belongs to the technical field of vegetative propagation of plants, and particularly relates to an accelerant facilitating plant cutting rooting.The accelerant is prepared from 4 parts of sinorhizobium fredii fermentation liquor, 3 parts of trichoderma aureoviride fermentation liquor, 4 parts of candida albican fermentation liquor, 3 parts of bacillus licheniformis fermentation liquor, 2 parts of gibberellin, 5 parts of grass carbon and 2 parts of dipotassium phosphate.The accelerant is a nutritional preparation special for asexual cutting rooting of torreya jackii, a good microecosystem can be formed, plant growth is promoted, beneficial microbiological florae are formed, nutrition environments of plant rhizosphere are improved, cutting rooting and the survival rate are greatly promoted, and an application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of plant asexual reproduction, and in particular relates to an accelerator for plant cutting and rooting. Background technique [0002] Long-leaf Torreya ( TorreyajackiiChan ), also known as Torreya chinensis and Torreya japonica, belonging to the genus Torreya yewaceae, is a relict gymnosperm plant remaining from the Cenozoic Tertiary period, a precious tree species unique to my country, and a wild plant under national second-level key protection. The taxonomy and flora's climatic response to the Quaternary Ice Age are of great significance. In addition, the long-leaved torreya is hard and fragrant, and can be used to make utensils. [0003] Long-leaved Torreya is an evergreen small tree or often a multi-branched shrub; branches are whorled or opposite, spreading or branchlets drooping; leaves are opposite, arranged in two rows, hard, linear-lanceolate, 3-13 cm long , 3-4 mm wide, first with acuminate ape...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, there are very few researches on the cutting propagation of Torreya torreya, because Torreya torreya is extremely rare in the wild, and there is no more suitable one in the market. Torreya torreya seeds have a very long maturity period and poor natural regeneration ability, so they are stored in warm sand for winter Or direct sowing, the germination rate is only 0.5-1%. In addition, the long-leaved torreya grows slowly, has high requirements on the environment, and grows extremely slowly, with an annual growth height of less than 1 cm, so it is more precious and rare.

The 2 Torreya torreya preserved by the Chinese Academy of Sciences in Jiangsu Province have passed for more than 50 years, but they have not borne fruit so far. The state of the art does not utilize the large-scale propagation of Torreya torreya. Therefore, studying the effective invisible propagation method of Torreya torreya can save Threatened torreya, shifting background of the species northward

The cutting method disclosed in the prior art (Application No. 2013101994490) has a low rooting rate and a long cutting propagation cycle. The inventor of the present application cooperated with the Chinese Academy of Sciences to improve on the basis of the existing technology and obtain excellent technical effects
