Problems solved by technology

[0003] In the prior art, although the single application of a plant growth regulator to hedge plants also has an obvious dwarfing effect, the duration of the dwarfing effect is often short, and it cannot have a good improvement effect on the leaf color of the plants.
In addition, application of a plant growth regulator alone results in an increase in the number of sprays, which also increases the input of manpower

Embodiment 1

[0027] figure 1 The preparation method of the plant growth retardant according to the embodiment of the present invention is shown. The steps of this preparation method are described in detail below:

[0028] Step 102: Prepare paclobutrazol solution, triiodobenzoic acid solution and abscisic acid solution

[0029] Paclobutrazol (Nanjing Dulai Biotechnology Co., Ltd., purity ≥ 98.0%) was dissolved in anhydrous methanol at a mass volume ratio of 1 g / 50 ml to prepare a paclobutrazol solution. Triiodobenzoic acid (Shandong West Asia Chemical Industry Co., Ltd., 2,3,5-triiodobenzoic acid, purity 98%) is dissolved in absolute ethanol with a mass volume ratio of 1g / 100ml, and is prepared into triiodobenzoic acid solution . Abscisic acid (Acros Reagent Company, USA, purity>98%) was dissolved in absolute ethanol at a mass volume ratio of 0.2-0.6 g / 10 ml to prepare an abscisic acid solution.

[0037] Orthogonal Experiment Design Scheme

[0038] Orthogonal experiment is carried out by using paclobutrazol solution, triiodobenzoic acid solution, abscisic acid solution and blank solution to prove the beneficial effect of the plant growth retardant claimed in the present invention. The design scheme of the orthogonal experiment is shown in Table 1 and Table 2.

[0039] The preparation method of the solution required for the orthogonal experiment is similar to the solution preparation method described in Example 1, and will not be repeated here.

Abstract

The invention relates to a plant growth retardant for garden hedge plants, a preparation method and application thereof. The plant growth retardant comprises a plant growth regulator, a fixing agent and a solvent, wherein the plant growth regulator comprises paclobutrazol, triiodobenoic acid and abscisic acid. In theplant growth retardant, mass / volume concentration of paclobutrazol is 600mg / L-800mg / L, mass / volume concentration of triiodobenoic acid is 50mg / L-100mg / L, mass / volume concentration of abscisic acid is 10mg / L-25mg / L, and volume ratio of the fixing agent is within the range of 0.08%-0.12%. In comparison with the prior art, by applying the plant growth retardant to hedge plants, height increment of plants can be reduced, overgrowth of new branches of hedge plants is inhibited to the maximum, leaf color is improved, and manual trimming times are reduced and ornamental value of hedge plants is increased. The plant growth retardant is suitable for Euonymus japonicas and other hedge plants of the approximate species.

Description

technical field [0001] The invention relates to the technical field of plant growth regulators, in particular to a plant growth retardant for garden hedge plants, a preparation method and application thereof. Background technique [0002] In the construction of urban greening, my country has invested a lot of money and labor, not only focusing on the ecological benefits of urban greening, but also on its ornamental value. Therefore, it has increased investment in landscape configuration and greening tree species shaping and pruning. As an important part of plant landscaping, hedge plants have been widely used in garden green spaces and have broad development prospects. However, hedge plants are resistant to pruning and have strong branching power. In order to better maintain their landscape and shape, a lot of manpower and material resources are invested in pruning and shaping them every year. Euonymus is often regarded as an important hedge tree species, which is represent...
