Background

Mango (the name Mangifera indica L., Latin) belongs to the genus Mangifera of the family Anacardiaceae, is a well-known tropical fruit and is one of the five major fruits in the world. Because of its tender meat quality, sweet flavor and high nutritive value, it is popular with people and has the name of "tropical fruit king".

However, during the development process of mango fruits, the mango fruits are very easily affected by temperature, illumination, weather, rainwater and the like, so that the mango fruits only bloom and cannot bear fruits, the fruiting rate is low, the quality of the obtained fruits is poor, the taste is sour and astringent, and huge losses are caused to fruit growers, so that during the actual planting process, a plant regulator is often needed to be used for growth regulation of the mango fruits. However, the effect of the plant regulator on the market at present is not obvious, the function is single, and the mango fruit can not be effectively elongated, enlarged, flowering-promoted and fruiting rate-promoted while the fruit quality is ensured. Therefore, there is a need to develop a plant growth regulator for mango that can improve the overall performance of mango fruits.

Detailed Description

The technical features of the technical solutions provided by the present invention are further clearly and completely described below with reference to the specific embodiments, and the scope of protection is not limited thereto.

The words "preferred", "more preferred", and the like, in the present invention refer to embodiments of the invention that may provide certain benefits, under certain circumstances. However, other embodiments may be preferred, under the same or other circumstances. Furthermore, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, nor is it intended to exclude other embodiments from the scope of the invention.

In order to solve the above technical problems, a first aspect of the present invention provides a plant growth regulating composition comprising the following components: gibberellin, forchlorfenuron, brassin and diethyl aminoethyl hexanoate.

Gibberellins

Gibberellin, CAS number 77-06-5, is a widely available plant hormone. The chemical structure of the compound belongs to diterpenoid acid and is derived from a tetracyclic skeleton.

Forchlorfenuron

Forchlorfenuron with CAS number of 68157-60-8 is a phenylurea plant growth regulator.

Brassin

Brassin, also called brassinolide, has CAS number of 72962-43-7, and is a high-efficiency, broad-spectrum and nontoxic plant growth regulator.

Diethyl aminoethyl hexanoate

Diethyl aminoethyl hexanoate, CAS number 10369-83-2, is a high energy plant growth regulator with broad spectrum and breakthrough effect.

In a preferred embodiment, the weight ratio of gibberellin, forchlorfenuron, brassin and diethyl aminoethyl hexanoate is 1: (1.5-2.0): (2.2-3.4): (0.5 to 1.5).

In a more preferred embodiment, the weight ratio of gibberellin, forchlorfenuron, brassin and diethyl aminoethyl hexanoate is 1: 1.8: 2.8: 1.

the inventor finds that in the continuous summary experiment exploration, when gibberellin, forchlorfenuron, brassin and diethyl aminoethyl hexanoate are used, the weight ratio is 1: (1.5-2.0): (2.2-3.4): (0.5 to 1.5), the plant growth regulator prepared from the obtained plant growth regulating composition can effectively elongate mango fruits after being used for regulating the growth process of mangoes. The inventor believes that forchlorfenuron can promote fruit cell division on one hand, thereby being beneficial to the formation of plant fruit organs; on the other hand, the compound can inhibit the decomposition of nucleic acid protein in plant leaves, delay the leaf senescence, and improve the content of auxin in plants under the synergistic action of gibberellin, so that the effect of fruit elongation is achieved, and meanwhile, the fruits are expanded to a certain extent. But easily causes the acidification of cell walls, so that the fruit tastes peracid. After a proper amount of brassin is compounded with the brassin, the nutrient supply structure of the plant can be adjusted, and the nutrient is adjusted to be transported to fruits, so that the growth and development of the fruits are promoted, and the generation of the sour fruits is reduced; the appropriate amount of diethyl aminoethyl hexanoate can further improve the activity of biological enzyme in plants, increase the content of chlorophyll, accelerate the photosynthesis speed, increase the content of organic substances such as saccharides, vitamins, amino acids and the like in fruits, ensure the taste of the fruits and effectively elongate the fruits.

The gibberellin is G4+7, purchased from Shanxi Send biochemicals Co., Ltd; the forchlorfenuron is purchased from Shaanxi Send Lange biochemical chemical engineering Co., Ltd; the brassin is purchased from Shaanxi Send Lange Biochemical engineering Co., Ltd; the diethyl aminoethyl hexanoate was purchased from southern Henan Spodot agricultural technologies, Inc.

In a preferred embodiment, the composition further comprises fructosamine.

Fruit amine

Dimethoxamine, also known as clofibric acid, is chemically known as m-chlorophenoxy isopropyl acid, has a CAS number of 101-10-0, and is an aryloxyalkanoic acid plant growth regulator.

In a preferred embodiment, the weight ratio of gibberellin to fructosamine is 1: (1.0-2.0).

In a more preferred embodiment, the weight ratio of gibberellin to fructosamine is 1: 1.5.

the inventor further researches and discovers that when the frusemide is added on the basis, the weight ratio of the gibberellin to the frusemide is 1: (1.0-2.0), the quality of the fruit is further improved after the obtained plant growth regulator is used for regulating the growth process of the mango. The inventor believes that the probable reason is that the activity of various enzymes (such as azotase) in the plant can be effectively improved and the increase of solid content accumulation can be improved by compounding the fructicide and other components according to a certain proportion; meanwhile, the nutrient circulation system of the fruit tree is improved, the toughness of fruit stalks of the fruits is improved to a certain extent, and the fruits are prevented from falling off before being immature, so that the fruit setting rate and fruit coloring of the mangoes are improved, the sugar content of the fruits is increased, and the fruit quality is improved.

The cycarpamine was purchased from zhengzhou alpha chemical company ltd.

In a preferred embodiment, the composition further comprises thidiazuron.

Thidiazuron

Thidiazuron, also known as defoliant, CAS number 51707-55-2, is commonly used as a defoliant in cotton planting, and can promote the natural formation of the separated tissues between the petioles and the stems to shed after being absorbed by plants, thus being a good defoliant.

In a preferred embodiment, the weight ratio of gibberellin to thidiazuron is 1: (0.1-0.5).

In a more preferred embodiment, the weight ratio of gibberellin to thidiazuron is 1: 0.3.
