Quick root accelerating method for Tamarix taklamakanensis M. T. Liu cutting slips

Abstract

The invention discloses a quick root accelerating method for Tamarix taklamakanensis M. T. Liu cutting slips. The method comprises the steps of collection and cutting of the cutting slips, rooting induction of the cutting slips, root accelerating culture in a hotbed, cuttage of the cutting slips and the like. According to the quick root accelerating method for the Tamarix taklamakanensis M. T. Liucutting slips, the structure of the root accelerating hotbed is reasonably designed, rooting induction and root accelerating in the hotbed are conducted by selecting appropriate rooting powder, and the root accelerating temperature and time are reasonably controlled, so that appropriate environmental conditions are created for the Tamarix taklamakanensis M. T. Liu cutting slips, and the coalescence and rooting of the cutting slip base portions are effectively accelerated; compared with a traditional Tamarix taklamakanensis M. T. Liu cuttage method, the cutting slip surviving rate is increasedby 10%, and the cutting slip breeding efficiency and the cuttage seedling-raising survive rate are obviously improved; the false-growth phenomenon occuring when the Tamarix taklamakanensis M. T. Liucutting slips germinate and grow shoots is effectively controlled, and the problems that the Tamarix taklamakanensis M. T. Liu cutting slip cuttage is difficult in rooting and low in breeding coefficient are solved.

Description

technical field [0001] The invention relates to a seedling-raising cutting technology, in particular to a rapid root-accelerating method for tamarisk cuttings suitable for northern regions. Background technique [0002] Tamarix taklamakanensis M.T.Liu, also known as Tamarix taklamakanensis M.T.Liu, belongs to the genus Tamarix of the family Tamaricaceae. It is a unique species in desert areas in my country. It is only distributed in the Taklamakan Desert in the Tarim Basin, Xinjiang, my country and the Kumta in the east of the basin. As a fixed pioneer tree species of shifting sand in the arid desert area of ​​our country, Tamarix sand-growing has strong ecological adaptability, ecological status and ecological significance; its distribution environment is harsh, facing endangered threats, and it is listed in the National List of Rare and Endangered Plants. At present, due to the gradual decline of groundwater level and the increasing salinity of sand surface soil among mobil...

AI Technical Summary

Problems solved by technology

The survival rate of tamarisk seeds is relatively high, but due to the short storage time of the seeds, the germination rate of the seeds will decrease rapidly with the prolongation of the storage time, so that the seed reproduction is greatly restricted; although the tissue culture rapid propagation method has a fast propagation speed, However, it is not suitable to master and use due to large capital investment and high technical requirements.

Therefore, cutting propagation has become an ideal choice, but at present Tamarix spp.

According to relevant reports from Turpan Botanical Garden in Xinjiang from 1981 to 1992, the survival rate of cuttings of Tamarix sylvestris was low; in 1998, the afforestation experiment of Tamarix sylvestris in Shandong concluded that all of them died in the second year after afforestation; The test shows that the average cutting survival rate of Tamarix sphaericus is lower than 60%.

Because the cuttings of Tamarix salicifolia germinate before the base heals, forming a false live phenomenon, the cuttings eventually die due to nutrient depletion, resulting in extremely low survival rate and cutting failure

Therefore, it will have very important practical significance to explore the hard branch cutting technology of Tamarix sylvestris in order to solve the technical problem of low survival rate of cutting seedlings of Tamarix sylvestris
