A kind of method of promoting casuarina lateral branch germination

Abstract

The invention belongs to the technical field of seedlings raising and discloses a method for promoting germination of lateral branches of casuarinas. The method comprises the following steps: utilizing large trees and old trees as material; promoting lateral branches of old trees or big trees of casuarinas to germinate new and small branches. The method comprises the methods of pulling small branches, pressing branches, chopping branches by half and inverting branches. The method is capable of germinating new branches in batch for lateral branches of casuarinas. The number of newly-germinated branches is almost equal to that of small branches originally growing on lateral branches before technical processing. The method for promoting germination of lateral branches of casuarinas has the following beneficial effects: roots easily grow out of new and small branches growing out of lateral branches of casuarinas than original and old branches; rooting rate can be up to more than 80%; and the rooting rate of old and small branches of casuarinas is almost zero.

Description

technical field [0001] The invention belongs to the technical field of tree seedling cultivation, and in particular relates to a method for promoting casuarina lateral branch germination. Background technique [0002] Casuarina is the main afforestation tree species for shelterbelts on thousands of kilometers of coastline in the southeast coast of my country. It has the advantages of wind resistance, fast growth, and barrenness resistance. Casuarina is effective in resisting typhoon attacks and preventing sea sand invasion, and effectively protecting farmland, roads, buildings and people. It has played a positive role in terms of life, etc., and can reduce the losses caused by natural disasters. At present, the seedling cultivation of casuarina basically adopts the seedling raising method of asexual reproduction, which can avoid the phenomenon of offspring variation caused by sexual reproduction. In the improved seedling cultivation of forest trees, casuarina vegetative prop...

Problems solved by technology

[0004] In summary, the problem in the prior art is that the traditional approach is to try to find individual newly sprouted twigs from the excellent single plant of casuarina, but its quantity is extremely small, and usually the twigs found are either too old or too long. Short, even if it can reproduce a few rooted seedlings, the planting of the seedlings is often difficult to survive because of its underdeveloped root system. Therefore, to obtain batches of casuarina germinate shoots, there is only another way; The method of obtaining casuarina twigs in batches from old trees or large trees
