Description

Technical Field

[0001] The invention relates to the technical field of plant growth regulators, and in particular to a composition and a preparation for controlling growth and increasing yield of ginger and an application thereof. Background Art

[0002] Ginger is widely planted in China, has high economic value and a long growth cycle. The hot and rainy summer is a critical period for the rapid growth of ginger, the accumulation of dry matter and the expansion of underground rhizomes. During this period, the ginger plants have many branches and weak stems. In addition, the heavy rain and high temperature in summer often cause the plants to grow too long, resulting in the transfer and loss of nutrients, which will affect the yield of underground ginger. The long growth of the plants will cause the field to be closed, the ventilation and air permeability will be poor, and it will also easily cause the aboveground part to fall, causing the breeding of pests and diseases and inconvenience in field management. Therefore, it is particularly necessary to carry out reasonable regulation during the vigorous growth period of ginger (rhizome expansion period). Summary of the invention

[0003] The purpose of the present invention is to provide a composition for controlling the growth of ginger and increasing its yield, so as to solve the problem that the ginger plant grows too long during the growth period and thus leads to low ginger yield.

[0005] The third object of the present invention is to provide a composition and a preparation for controlling the growth of ginger and increasing its yield, and to use the composition in ginger planting to solve the problem of low ginger yield caused by excessive growth of ginger plants during the growth period.

[0006] In order to solve the above technical problems, the technical solution of the composition for controlling the growth and increasing the yield of ginger of the present invention is: A composition for controlling growth and increasing yield of ginger, comprising indolebutyric acid and 1-aminocyclopropanecarboxylic acid in a mass ratio of 1:(5-30).

[0007] The present invention improves the prior art and provides a composition for controlling the growth of ginger and increasing its yield. By compounding indolebutyric acid and 1-aminocyclopropanecarboxylic acid, the excessive growth of the aboveground part of ginger can be controlled, and the lodging phenomenon during the vigorous growth period can be reduced, thus having a significant effect on increasing the yield of ginger.

Moreover, at the same dosage, the combination of indolebutyric acid and 1-aminocyclopropanecarboxylic acid shows a better effect of controlling vigorous growth and increasing yield than the combination of indolebutyric acid and ethephon.

[0018] In order to further improve the yield increase rate, preferably, the preparation is diluted and applied to ginger during the rhizome expansion period, and the content of the active ingredient in the diluted preparation is 120-640 mg / kg. DETAILED DESCRIPTION

[0019] The technical concept of the composition for controlling growth and increasing production of ginger of the present invention is as follows: Indolebutyric acid is an auxin-type plant growth regulator that 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. It can promote cell division, elongation, and expansion, induce the formation of rhizogenes, and is beneficial to the growth of new roots and the differentiation of the vascular system, and promote the formation of adventitious roots of cuttings; it can also promote RNA synthesis, attract and transport nutrients to the treated parts, regulate the development of roots, flowers, and fruits, increase fruit setting, prevent fruit drop, change the ratio of female to male flowers, etc., and at the same time increase the stress resistance of crops.

[0020] 1-Aminocyclopropanecarboxylic acid (ACC), as a new type of plant growth regulator, is a direct precursor of endogenous ethylene produced by plants. Its biosynthesis process is: methionine-S-adenosylmethionine-ACC-ethylene. Methionine is first converted into S-adenosylmethionine, which is then catalyzed by ACC synthase to produce ACC, and ACC is oxidized to produce ethylene under the catalysis of ACC oxidase.

[0021] When ACC is applied to plants, it has the characteristic "triple reaction" of ethylene. Exogenous supplementation of ACC is an effective way to increase the concentration of ethylene in plants, causing crop-related physiological functions, such as enhancing peroxidase activity, reducing apical dominance, controlling plant leggy growth, increasing effective distribution, and promoting the transportation and transformation of nutrients from stems and leaves to fruits, making the fruits mature early and evenly.

[0022] ACC is a better ethylene releaser than ethephon and has a wide range of application prospects. ACC is endogenous to plants and directly participates in the metabolism of plants, while ethephon is exogenous and participates in plant physiological activities only after being decomposed into ethylene. ACC is regulated by ACC enzymes in plants and is not affected by pH and temperature. Its properties are stable, while ethephon is greatly affected by external factors such as temperature and water quality.

[0023] The invention adopts indolebutyric acid and 1-aminocyclopropanecarboxylic acid in a mass ratio of 1: (5-30) for compounding. Through the synergistic effect of the two plant growth regulators, the excessive growth of the aboveground part of ginger can be controlled, the stem thickness can be increased, the rhizome weight can be increased, the lodging phenomenon in the vigorous growth period can be reduced, the nutrient transfer and loss can be reduced, and then the yield of underground ginger pieces can be increased.
