Embodiment Construction

[0048] The present invention will be further described below with reference to specific embodiments.

[0049] The method for building a group of dwarf species of Lagerstroemia genus Lagerstroemia in the present invention comprises the following steps:

[0050] 1. Establish a dwarf crape myrtle variety resource nursery: extensively collect existing dwarf crape myrtle varieties with short plants and small leaves and use various breeding methods to select corresponding parental innovation dwarf crape myrtle varieties, and establish a dwarf crape myrtle variety resource nursery;

[0051] 2. Testing of dwarf crape myrtle varieties, the testing methods specifically include:

[0052] 2A. Selection of test varieties (materials): choose Lagerstroemia myrtle varieties (or materials) with relatively short growth and small leaves from the resource nursery;

[0053] 2B. Propagation of test materials: the selected varieties or materials are all produced by cutting propagation method to pro...

Abstract

The invention relates to a method for building a dwarf plant species of the genus Lagerstroemia genus Lagerstroemia, belonging to the technical field of plant cultivation. Including the following steps: 1. Establish a resource nursery for dwarf crape myrtle varieties; 2. 3. Test of dwarf crape myrtle varieties; Tested characteristic items and records; 4. Comprehensive evaluation index; 5. Establishment of classified variety groups based on test results. The present invention overcomes the defects of the prior art, and the established dwarf crape myrtle variety group can better satisfy small-sized potted plants, flower bed arrangements, flower mirrors and others due to low plants, strong branching ability, good flowering density and good ornamental performance. The production of dwarf crape myrtle seedlings required for green space landscape construction, thereby expanding the commodity types of crape myrtle seedlings, broadening the application field, enhancing the commodity value of stump bonsai and enriching the garden landscape, while improving the economic benefits of seedling production.
