Hard wood cutting seedling culture method of Tamarix taklamakanensis

Abstract

The invention discloses a hard wood cutting seedling culture method of Tamarix taklamakanensis. The method comprises the following steps of (1) cutting collection and pruning; (2) cutting rooting induction; (3) cutting forcing cultivation in bootbed; (4) cutting seedling culture in a container; (5) rooting seedling field transplantation. According to the hard wood cutting seedling culture method of Tamarix taklamakanensis, appropriate rooting powder is selected for rooting induction and cutting forcing treatment in bootbed, so that healing and rooting of the bases of cuttings are effectively promoted; moreover, through rational control over the cutting forcing temperature and time, environmental conditions of low air temperature and high earth temperature are created for the cuttings of Tamarix taklamakanensis; compared with a traditional cutting method of Tamarix taklamakanensis, the survival rate of the cuttings is increased by 10 percent; by means of the hard wood cutting method ofTamarix taklamakanensis, the growth is fast, the survival rate is high, the seedling culture period is obviously shortened, and the cutting reproduction efficiency and the cutting seedling culture survival rate are obviously improved; the pseudo alive phenomenon that the cuttings of Tamarix taklamakanensis sprout is effectively controlled, and the problems that by means of cutting of the cuttingsof Tamarix taklamakanensis, rooting is difficult and the reproduction coefficient is low are solved.

Description

technical field [0001] The invention relates to seedling-raising cutting technology, in particular to a method for raising seedlings of tamarisk hardwood cuttage 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 mo...

Problems solved by technology

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%.

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

Although the survival rate of tamarisk seeds is relatively high, due to the short storage time of seeds, the germination rate of seeds will decrease rapidly with the prolongation of storage time, which greatly restricts the propagation of seeds

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
