Problems solved by technology

However, Siberian apricot trees are difficult-to-root species of cuttings. Without treatment, the cuttings basically do not take root. Dong Shengjun et al. (2013), Dai Fei et al. optimized, but the rooting rate of cuttings is still low
At present, there is still a lack of effective means to improve the rooting of Siberian apricot tree cuttings and optimize the growth characteristics of cutting seedlings

Abstract

The invention provides a cutting seedling raising method for Armeniaca sibirica, and relates to the technical field of vegetative propagation of plants. The cutting seedling raising method for the Armeniaca sibirica comprises the steps of cutting slip selection, cutting slip treatment, cutting, rooting management and transplanting seedling raising, wherein cutting slips are soaked in IBA with the concentration of 400-800 mg / L and salicylic acid with the concentration of 200-600 mg / L, turf, mountain base soil and river sand are mixed according to the volume ratio of (1-3): (3-5): (1-3) to serve as a cutting medium, the rooting rate of the Armeniaca sibirica cutting slips and the growth traits of cutting seedlings can be obviously improved, and the problem that the Armeniaca sibirica cutting is difficult to root is solved.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a cutting seedling raising method of Siberian apricot trees. Background technique [0002] Siberian apricot tree (Armeniaca sibirica (L.) Lam.), also known as mountain apricot, is a shrub or small tree of the genus Apricot in the family Rosaceae. It is mainly distributed in Siberia of Russia, eastern and southeastern Mongolia, and my country's Inner Mongolia, Beijing, Shanxi, Liaoning, Jilin, Heilongjiang, Xinjiang, Tibet and other regions. Siberian apricot has the characteristics of cold resistance, drought resistance, wind and sand resistance, barren resistance, and well-developed root system. It is an excellent tree species for sand-fixing, soil conservation, water conservation, and ecological environment improvement. In addition, the kernels of Siberian apricots are commonly used medicinal materials in the medical field, and can also be used ...
