Problems solved by technology

[0003] Because the branches of crape myrtle seedlings are often twisted and the twigs are slender, if they are allowed to grow during the seedling cultivation stage, the success rate will be extremely low and the planting cost will be high

Embodiment 1

[0028] A kind of crape myrtle anti-lodging planting method that the present embodiment provides, described method comprises the steps:

[0029] Step 1. Selecting parents: selecting crape myrtle from different origins with good stress resistance, fast growth, thick stalks and low fiber content as parents of tetraploid breeding source plants;

[0030] Step 2. Induction: When the flower buds of Lagerstroemia indica parents are not open, chemical inducers are used to induce the flower buds, so that the chromosomes of the flower organs are multiplied, so that they can produce male and female gametes containing two sets of chromosomes;

[0031] Step 3, hybridization: hybridize the induced flower buds with the normal flower buds for pollination, and obtain hybrid seeds after the plants become fruity;

[0032] Step 4, detection: the hybrid seeds are cultivated into seedlings by aseptic sowing, and tetraploid plants are detected;

[0033] Step 5, asexual reproduction: asexual reproduc...

Abstract

The invention belongs to the technical field of agricultural product processing, and provides a lodging resistant planting method of crape myrtle. The innovative thinking of the invention is to applya biological method to the planting of crape myrtle so as to achieve the purpose of lodging resistance. According to the method, firstly, a method of induction by a chemical inducer is adopted to obtain tetraploid crape myrtle seedlings, and then the tetraploid crape myrtle seedlings are planted, wherein the branches of the tetraploid crape myrtle seedlings are thick and robust, the yield is high,and the planting cost is high. In the planting process, support frames are manually arranged for fixing the seedlings; through the culture of the tetraploid seedlings and with the combination of manual fixing in a growth process of the seedlings, the lodging phenomenon in the growth process of the crape myrtle can be prevented, the windage resistance of the crape myrtle can be prevented, and thevertical upward growth of the branches of the crape myrtle seedlings can be ensured.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a method for planting crape myrtle against lodging. Background technique [0002] Lagerstroemia, also known as barkless tree, is a small deciduous tree. The flowering period is from June to September. The crape myrtle tree is beautiful, the trunk is smooth and clean, and the flowers are gorgeous; when it blooms, it is the season of few flowers in summer and autumn. , light red, purple and white, its flowering period is long, known as "hundred-day red", it is a good tree for viewing dry and flowering greening. [0003] Because the branches of crape myrtle seedlings are often twisted and the twigs are slender, if they are allowed to grow during the seedling cultivation stage, the success rate will be extremely low and the planting cost will be high. [0004] The invention provides a method for planting crape myrtle against lodging. Contents of...
