Problems solved by technology

[0003] In the cultivation process of alpine Rhododendron, the most common technique is the lateral root induction technique, and in the experimental process of lateral root induction, in order to improve its ability to inhibit pathogenic bacteria, an appropriate amount of Bacillus will be added to it as a biological bacteria, but in sunlight Ultraviolet rays have a fatal killing effect on spores, and ultraviolet radiation can also produce deformation and reduction effects on paraspore crystals, so there are certain restrictions on the use of bacillus; It makes potions, but based on the current technology, the moistening and adhesion effect of potions on rhododendrons is poor, resulting in low potion effects. In addition, alpine rhododendrons generally have thinner roots, which have a certain impact on their growth

Embodiment

[0037] S1, branch selection: remove the end of the Rhododendron alpine with curled leaves, and remove the flower buds, use this as a branch, and set aside;

[0038] S2. Sterilization treatment: soak the roots of the branches in thiophanate-methyl solution with a concentration of 500mg / L, soak for more than half a day, take out and dry naturally after disinfection;

[0039] S3, preparation of nutrient solution: ABT rooting powder, gibberellin and water are mixed uniformly by mass ratio 3:1:5 to make a plant growth regulator, then add bacillus and ultraviolet absorption aids to the plant growth regulator, After stirring and mixing, the nutrient solution is obtained;

[0040] Among them, the ultraviolet absorption aid in S3 is made of PEG-b-PE UV-0 It is mixed with isoamyl p-methoxycinnamate in a mass ratio of 3:1;

[0041] S4, branch treatment: strip the root epidermis of the branch after S2 sterilization, then its root is soaked in the vitamin solution for 10 hours, take it o...

Abstract

The invention relates to the technical field of lateral root induction, in particular to a technical method for lateral root induction of rhododendron lapponicum, The technical method comprises the following steps: S1, branch selection: removing tail ends with rolled leaves from the rhododendron lapponicum, and picking off flower buds to obtain branches for later use; S2, sterilization treatment: soaking the roots of the branches in a thiophanate methyl solution for more than half a day, and taking out the branches for natural air drying after disinfection; and S3, preparation of a nutrient solution: uniformly mixing ABT rooting powder and gibberellin with water in proportion to prepare a plant growth regulator, adding bacillus and an ultraviolet absorption aid into the plant growth regulator, and uniformly stirring and mixing to obtain the nutrient solution. According to the method, the inhibition effect of the rhododendron lapponicum on ultraviolet rays can be improved, the activity of bacillus is guaranteed, the root development of the rhododendron lapponicum can be remarkably promoted, and in addition, the wettability of the surface of the rhododendron lapponicum can be improved, so that the effect of the medicine is improved.

Description

technical field [0001] The invention relates to the technical field of lateral root induction, in particular to a technical method for alpine rhododendron lateral root induction. Background technique [0002] Alpine Rhododendron mainly grows in mountains, tundra, rocky places or swampy areas. Compared with ordinary rhododendrons, alpine rhododendrons can not only maintain lush flowers and leaves all year round, and the leaves are not easy to fall off, but also can survive in cold regions and have stronger vitality. [0003] In the cultivation process of alpine Rhododendron, the most common technique is the lateral root induction technique, and in the experimental process of lateral root induction, in order to improve its ability to inhibit pathogenic bacteria, an appropriate amount of Bacillus will be added to it as a biological bacteria, but in sunlight Ultraviolet rays have a fatal killing effect on spores, and ultraviolet radiation can also produce deformation and reduct...
