Breeding method of North Ameria tulip trees by using transplanting cuttings

Abstract

The invention belongs to the cutting propagation combination technology of forest trees, and specifically provides a cutting propagation method of Liriodendron tulipifera, and simultaneously provides a matching incision anti-corrosion rooting paste film. The present invention is also applicable to the propagation of Chinese mantle tree. The present invention solves the shortcomings of long rooting time and perishable cuttings of Liriodendron tulipifera in the prior art through the reasonable combination of cutting selection, soil cultivation configuration, antiseptic rooting paste film formula and spray moisturizing management, and provides a set of The formula and propagation method can prevent rot of cuttings and accelerate rooting, and the survival rate of repeated cuttings is stable at more than 85%.

Description

【Technical field】 [0001] The invention belongs to the cutting propagation combination technology of forest trees, and specifically provides a cutting propagation method of Liriodendron tulipifera, and simultaneously provides a matching incision anti-corrosion rooting paste film. The present invention is also applicable to the propagation of Chinese mandarin mandarin trees. 【Background technique】 [0002] Liriodendron tulipifera L. is naturally distributed in the eastern part of the United States and the southeastern part of Canada, and is mainly concentrated in the Appalachian mountains. Two species distributed intermittently in East Asia and North America. Similarly, Liriodendron (Liriodendron) has excellent material, peculiar leaf shape, large and beautiful flowers, tall tree body, and strong stress resistance. It is an ancient plant evolved after the origin of the warm climate era in the Oligocene. , industrial materials, ecological environment construction and other as...

Problems solved by technology

Most of them are the test results of indoor artificial environment, and have not yet formed a scale, and there are no reports of asexual rapid propagation put into production and utilization, so the production practice is of little significance

[0005] In the United States, although there are reports of tissue culture and rapid propagation using immature embryos (MerkleS.A., et al., Plant Cell, Tissue and Organ Culture, 1993, 34: 192-198), the use of immature embryos The seedlings produced by tissue culture and rapid propagation of embryos have disadvantages such as unclear genetic background, inability to guarantee good traits, high cost, and the need to wait a long time until flowering and fruiting to obtain reproductive materials.

Therefore, the difficulty of vegetative propagation of Liriodendron tulipifera has become a technical bottleneck restricting the large-scale propagation, popularization and application of this tree species and its excellent germplasm materials in my country.
