Container cutting method of crape myrtle twigs

Abstract

The invention relates to a crape myrtle tender branch vessel cuttage method and belongs to the technical field of plant cutting. The crape myrtle tender branch vessel cuttage method comprises the following steps including the first step of cutting medium and vessel preparation, the second step of cutting spike selection, the third step of the cuttage process, the fourth step of the transplanting process, the fifth step of follow-up management and the sixth step of seedling adaptation, wherein S1, the cutting medium and vessel preparation is conducted, and sterilized perlite, an organic cutting medium, a nutrition pot, a cuttage disk and a water tank are prepared; S2, the cutting spike selection is conducted, and crape myrtle tender branches are selected for cuttage; S3, the cuttage process is conducted, and the crape myrtle tender branches are put into the water tank in a cuttage mode; S4, the transplanting process is conducted, and after callus tissues of the crape myrtle tender branches subjected to the cuttage are formed, the crape myrtle tender branches are transplanted into the nutrition pot and urgently need to be cultivated in the water tank; S5, the follow-up management is conducted, water level in the water tank is kept, and perpendicular incidence of sunshine on the water tank needs to be avoided; S6, the seedling adaptation is conducted, and then the cultivation is completed after the seedling adaptation. By means of the crape myrtle tender branch vessel cuttage method, the defect that entire tender branches can not be used in the existing crape myrtle cuttage technology is overcome, cuttage breeding production can be conducted in the whole crape myrtle growing season, large-scale crape myrtle breeding can be achieved, the survival rate is high, the finished products after the cuttage are container-grown seedlings, and the long-distance transport is facilitated.

Description

technical field [0001] The invention relates to a seedling raising method in agricultural planting, in particular to a container cutting method of crape myrtle twigs. Background technique [0002] Lagerstroemia crape myrtle is a plant of the genus Lagerstroemia genus in the genus Lagerstroemia. It is distributed in South China and Central my country, and is a commonly cultivated ornamental plant. In hot summer, when the group of flowers converges, only Lagerstroemia inflorescence blooms, and the flowering period is as long as 120 days, so it is also called "hundred-day red". It is the most commonly used tree species in landscaping and has high cultivation value. [0003] There are two main methods of cutting and propagating crape myrtle at present: one is to collect annual branches before the branches germinate in spring, cut the cuttings into about 15cm long cuttings, and insert them into loose and well-drained sandy loam seedbeds, with axillary buds exposed at the top. Th...

Problems solved by technology

Although this method uses new shoots and twigs for cuttings, the requirement is that the semi-lignified branches will be grown in the same year, and the whole twigs cannot be fully utilized, which wastes the resources of twigs. In addition, the help of corresponding agricultural facilities and electronic spraying facilities is required. Complete cutting propagation

Moreover, the above methods are all non-container cuttings, and the young seedlings can only be cultivated naked, which is not suitable for the large transportation demand in modern forestry cultivation, and will cause certain losses

[0004] It can be seen that the existing crape myrtle cutting propagation technology can only be carried out at specific times in spring and summer, and the cuttings are all made of lignified or semi-lignified branches of the current year or more than one year, and it is necessary to wait for the seedlings to grow to a certain level. Cutting operations can only be carried out at a certain level, the cultivation method is complicated, and a lot of equipment is required for management, and all of them are non-container cuttings, which is inconvenient for transplanting
