Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant growth regulators, in particular to a composition for controlling the growth of ginger to increase yield, a preparation and application thereof. BACKGROUND

[0002] Ginger is widely planted in China, has high economic value and a long growth cycle. The summer with high temperature and heavy rain is a critical period for rapid growth, promoting dry matter accumulation and underground tuber swelling of ginger. During this period, ginger plants have many branches, and the stems are weak. In addition, the summer is often rainy and hot, which often leads to plant overgrowth, nutrient transfer loss, and thus affects the yield of underground ginger tubers. Plant overgrowth causes poor ventilation and air permeability in the field, which can also easily cause the aboveground part to lodge, causing disease and pest breeding and inconvenience in field management. Therefore, it is particularly necessary to reasonably control during the vigorous growth period of ginger (tuber swelling period). SUMMARY

[0003] The purpose of the present application is to provide a composition for controlling the growth of ginger to increase yield, to solve the problem of low ginger tuber yield caused by plant overgrowth during the vigorous growth period of ginger.

Moreover, compared with compounding ethylene with 1-aminocyclopropane carboxylic acid, the compounding of indole butyric acid with 1-aminocyclopropane carboxylic acid shows a better effect of controlling vigorous growth and increasing yield.

[0021] In order to further improve the yield-increasing rate, preferably, the preparation is diluted and applied to the ginger in the rootstock enlargement period, and the effective ingredient content in the diluted preparation is 120-640 mg / kg. Detailed Implementation

[0022] The technical concept of the composition for controlling excessive growth and increasing yield in ginger according to the present invention is as follows:

[0023] Indolebutyric acid (IBA) is a plant growth regulator belonging to the auxin class. It can be absorbed by the roots, stems, leaves, and fruits of plants. Its mechanism of action is consistent with that of the endogenous plant auxin indoleacetic acid (IAA). It can promote cell division, elongation, and expansion, induce the formation of root primordia, which is beneficial to the growth of new roots and the differentiation of the vascular bundle system, and promote the formation of adventitious roots of cuttings. It can also promote RNA synthesis, attract and transport nutrients to the treated site, regulate the development of roots, flowers, and fruits, increase fruit set, prevent fruit drop, change the ratio of female to male flowers, and increase the crop's stress resistance.

[0024] 1-Aminocyclopropanecarboxylic acid (ACC), a novel plant growth regulator, is a direct precursor for the synthesis of endogenous ethylene in plants. Its biosynthetic process is as follows: methionine → S-adenosylmethionine → ACC → ethylene. Methionine is first converted to S-adenosylmethionine, which is then catalyzed by ACC synthase to generate ACC. ACC is then oxidized to ethylene under the catalysis of ACC oxidase.

[0025] When ACC is applied to plants, it exhibits the characteristic "triple response" of ethylene. Exogenous ACC supplementation is an effective way to increase the concentration of ethylene in plants, which induces related physiological functions in crops, such as enhancing peroxidase activity, reducing apical dominance, controlling excessive plant growth, increasing effective secretion, promoting the transport and conversion of nutrients from stems and leaves to fruits, and making fruits ripen earlier and more uniformly.

[0026] ACC is a better ethylene release agent than ethephon and has broad application prospects. ACC is endogenous in plants and directly participates in plant metabolism, while ethephon is exogenous and only participates in plant physiological activities after being broken down into ethylene. ACC is regulated by the ACC enzyme in plants and is not affected by pH and temperature, making it stable, while ethephon is more affected by external factors such as air temperature and water quality.

[0027] This invention uses a compound of indolebutyric acid and 1-aminocyclopropanecarboxylic acid in a mass ratio of 1:(5~30). Through the synergistic effect of the two plant growth regulators, it can control the excessive growth of the above-ground parts of ginger, increase stem diameter, increase root and stem weight, reduce lodging during the vigorous growth period, reduce nutrient transfer and loss, and thus increase the yield of underground ginger rhizomes.

[0067]

[0068] Application time and dosage: When the ginger is in the vigorous growth stage (rhizome expansion stage), the preparation is sprayed for 2 times continuously and uniformly with an interval of 10-15 days.
