Description

Technical Field

[0001] The invention relates to the technical field of plant growth regulators, and in particular to a growth regulator for bamboo shoots and a preparation process thereof. Background Art

[0002] Growth regulators are a class of chemical substances or biological agents used to promote plant growth, increase yield and quality. These regulators can promote plant growth by regulating the plant's endogenous hormone levels, improving nutrient absorption and utilization, and enhancing stress resistance. Generally, people will spray growth regulators on the roots of bamboo shoots to improve the nutrient absorption level of the roots of bamboo shoots, thereby promoting the growth of bamboo shoots. This is because the roots are the main absorption organs of bamboo shoots, and after being absorbed by the plants, the growth regulators do not provide nutrients to the plants, but instead act as growth hormones to promote the cells at the roots of bamboo shoots to absorb water and nutrients from the soil.

[0003] Existing bamboo shoot growth regulators often use kinetin and cytokinin. Kinetin is a plant growth regulator and a type of cytokinin. It was first isolated from RNA degradation products and has the functions of promoting cell division and delaying cell aging. Kinetin mainly promotes the growth of bamboo shoots by promoting cell division and increasing the number of cells. It can stimulate the activity of the apical meristem and lateral buds of bamboo shoots, thereby promoting the elongation growth of bamboo shoots. Bamboo shoots promoted by the use of kinetin will significantly increase their height compared to bamboo shoots not sprayed with growth regulators, but the basal diameter of the bamboo shoots themselves will not increase. In fact, due to the excessive height of the bamboo shoots, the root system is short of nutrients, the roots of the bamboo shoots no longer grow, and the bamboo shoots become thinner as a whole. Ethyleneconazole regulates plant growth by inhibiting the synthesis of endogenous gibberellins (GA) in plants. Ethyleneconazole inhibits the biosynthesis pathway of gibberellins, especially by inhibiting the activity of gibberellin 3β-hydroxylase, which synthesizes gibberellins, thereby reducing the content of gibberellins in the plant. This leads to the inhibition of bamboo shoot cell elongation and the slowdown of longitudinal growth rate, thereby slowing down the initial stem elongation of bamboo shoots, assisting the development of the bamboo shoot root system, and improving the ability of bamboo shoots to absorb nutrients. In the later stage, after the bamboo shoot root system is fully developed, Ethyleneconazole is metabolized and the bamboo shoots grow longitudinally. At this time, the nutrients absorbed by the bamboo shoots are more sufficient, thereby promoting the growth of bamboo shoots.

[0004] However, unlike kinetin, succinimide is not an endogenous plant hormone. Therefore, when sprayed from the outside, bamboo shoots have limited absorption capacity for succinimide. Succinimide is easily volatilized, resulting in a small absorption of succinimide by the bamboo shoot roots. Generally, in this case, the dosage of succinimide needs to be increased. However, succinimide volatilizes quickly and remains in the soil for a long time. In addition, the main function of succinimide is to inhibit plant growth. Randomly increasing the dosage of succinimide may affect subsequent crops, resulting in excessive growth inhibition of subsequent crops and affecting normal growth and development.

[0005] Therefore, the present invention provides a growth regulator for bamboo shoots and a preparation process thereof to solve the above problems. Summary of the invention

[0028] Compared with the prior art, the present invention has at least the following beneficial effects:

[0029] 1. The present invention compounds uniconazole and zinc acetate. Uniconazole is a plant growth regulator that can inhibit the biosynthesis of endogenous gibberellins in plants, thereby slowing down stem elongation and promoting the development of the root system. Zinc is one of the trace elements necessary for plant growth. Zinc acetate can promote the growth of the root system and increase the absorption capacity of the root system. O, N and S atoms in uniconazole molecules can serve as coordination atoms to form coordination bonds with metal ions. The zinc ions in zinc acetate form coordination bonds with the coordination atoms through electrostatic and covalent interactions, while the carboxyl groups in acetic acid can serve as auxiliary coordination atoms to participate in the formation of a more complex complex, help stabilize the coordination bonds between uniconazole and zinc ions, and improve the stability of the complex. Uniconazole and zinc acetate form a stable, non-volatile, and synergistic complex, which further promotes the development of the bamboo shoot root system, enhances its ability to absorb water and nutrients, enables plants to more efficiently utilize nutrients in the soil, and promotes overall growth.

[0030] 2. The present invention prepares a microemulsion with a zinc complex of pea protein and gum arabic after compounding. Pea protein is a natural protein with good emulsification and stability. It can form a stable emulsion to prevent the aggregation and precipitation of uniconazole in water. Gum arabic is a natural polysaccharide with excellent emulsification and thickening properties. It can form a stable interface film between water and oil to prevent the emulsion from breaking. The emulsion of pea protein and gum arabic can form a protective film after release to prevent uniconazole from being released too quickly, prolonging its action time on the plant surface, thereby improving the attachment rate and utilization rate of uniconazole on the root system of the fabric, promoting the development of the root system of bamboo shoots, enhancing its ability to absorb water and nutrients, and promoting the overall growth of bamboo shoots.

[0073] Comparative Example 1:

[0074] Comparative Example 1 is a growth regulator for bamboo shoots on the market.

[0075] Comparative Example 2:

[0076] Compared with Example 1, the difference of Comparative Example 2 is that zinc chloride is added instead of zinc acetate in step S1.1, specifically: "S1.1: 0.5 parts by mass of uniconazole is placed in a reaction bottle, and 10 parts by volume of a methanol solution is added to dissolve it, and then 0.2 parts by mass of zinc chloride is dissolved in 5 parts by volume of methanol to obtain a zinc chloride methanol solution;

[0077] S1.2: adding zinc chloride methanol solution dropwise into uniconazole at a volume ratio of 1:2, stirring magnetically at 200 r / min for 4 h to obtain a composite solution, filtering, standing for 36 h, and drying at 60°C for 3 h to obtain an uniconazole zinc complex. The remaining steps remain unchanged, and the prepared bamboo shoot growth regulator is recorded as Comparative Example 2.

[0078] Comparative Example 3:

[0079] Compared with Example 1, the difference of Comparative Example 3 is that pea protein is not added in step S2.2, specifically: "S2: preparing a composite emulsion

[0080] S2.1: Gum arabic and deionized water were mixed in a mass ratio of 2:10, and then the concentration of gum arabic was adjusted to 0.1wt% by adding deionized water, and the pH value was adjusted to 6, and the mixture was stirred at room temperature for 4h, and refrigerated in a refrigerator at 0°C for 12h to obtain a composite emulsion. The remaining steps remained unchanged, and the prepared bamboo shoot growth regulator was recorded as Comparative Example 3.

[0081] Comparative Example 4:

[0082] Compared with Example 1, the difference of Comparative Example 4 is that gum arabic is not added in step S2.2, specifically: "S2: preparing a composite emulsion

[0083] S2.1: Peas were crushed and passed through an 80-mesh sieve to obtain pea flour, and the pea flour was mixed with distilled water at a solid-liquid ratio of 1 g:10 mL, heated to 45°C, and the pH value was adjusted to 9.5, stirred for 2 h, centrifuged at 4500 r / min for 20 min, the supernatant was taken, the pH value of the supernatant was adjusted to 4.5, and centrifuged again at 4500 r / min for 20 min, the precipitate was collected, and freeze-dried for 6 h to obtain pea protein;

[0084] S2.2: pea protein and deionized water were mixed in a mass ratio of 1:10, and then the concentration of pea protein was adjusted to 0.1wt% by adding deionized water, and the pH value was adjusted to 6, stirred at room temperature for 4h, and refrigerated in a refrigerator at 0°C for 12h to obtain a composite emulsion. The remaining steps remained unchanged, and the prepared bamboo shoot growth regulator was recorded as Comparative Example 4.

[0085] The new bamboo shoots with the same growth potential were grouped into 5 groups to prepare 8 groups. Examples 1-3 and Comparative Examples 1-4 were taken and 7 groups of bamboo shoots were sprayed respectively. There was also a blank group that was not sprayed with any growth regulator. The 7 groups of bamboo shoots in Examples 1-3 and Comparative Examples 1-4 were sprayed once every 4 days for 1 month. After the bamboo shoots grew for 4 months, they were counted, the basal diameter and length of the root system of the bamboo shoots were measured, and the average basal diameter and average length of each group were statistically tabulated, as shown in Table 1.

[0086] Table 1

[0087]

[0088] The average base diameter of Example 1 is 12.6 cm, and the average length is 53.6 cm. The average base diameter of Example 2 is 12.9 cm, and the average length is 54.4 cm. The average base diameter of Example 3 is 12.7 cm, and the average length is 52.9 cm. The average base diameter of the blank group is 7.8 cm, and the average length is 36.4 cm. It can be seen that after using the growth regulator for bamboo shoots of the embodiment, the average base diameter of the bamboo shoots is larger and the average length is longer, indicating that the bamboo shoots absorb more nutrients after using the growth regulator and develop better.

[0089] The average base diameter of Comparative Example 1 is 11.3 cm, and the average length is 48.5 cm. The average base diameter and average length of the embodiment are larger than those of Comparative Example 1. It can be seen that the average base diameter and average length of Embodiments 1-3 are all greater than those of Comparative Example 1. Comparative Example 1 is a commercially available bamboo shoot growth regulator, which means that the growth regulator of the embodiment can promote the root growth of bamboo shoots. Therefore, the average base diameter of the bamboo shoots of the embodiment is larger than that of Comparative Example 1. In addition, the growth regulator for bamboo shoots of the embodiment can better assist the roots of bamboo shoots to absorb nutrients and water. Therefore, the average length of the bamboo shoots of the embodiment is also longer than that of Comparative Example 1. It can be seen that the growth regulator for bamboo shoots prepared by the present invention is better than commercially available products.

[0090] The average base diameter of Comparative Example 2 is 10.5 cm, and the average length is 43.2 cm, indicating that zinc acetate and linconazole are not used to prepare the bamboo shoot growth regulator. Zinc chloride and linconazole cannot produce a synergistic effect to promote the absorption of nutrients by the bamboo shoot roots. There is no carboxyl group in acetic acid to assist in coordination and participate in the formation of a more complex complex. It is difficult to form a stable coordination bond between linconazole and zinc ions, resulting in instability of the complex, which is volatile and cannot promote the development of the bamboo shoot roots, resulting in the root development being not as good as in the embodiment, and the growth and development being not as good as in the embodiment.

[0091] The average base diameter of comparative example 3 is 9.4 cm, and the average length is 44.1 cm. The average base diameter of comparative example 5 is 8.6 cm, and the average length is 37.5 cm. It can be seen that the microemulsion prepared by combining pea protein and gum arabic can assist viniconazole to adhere to the plant surface and prevent viniconazole from being released too quickly, thereby enhancing the water and nutrient absorption capacity of bamboo shoots. However, single pea protein or gum arabic is difficult to form a stable and uniform emulsion, and it is also impossible to form a protective film after release. The growth regulator for bamboo shoots with viniconazole zinc complex as the main drug cannot be immediately absorbed in large quantities by bamboo shoots, and viniconazole will be rapidly released and volatilized over time. There is no protective film to prevent viniconazole from volatilizing. The absorption capacity of bamboo shoots for viniconazole decreases, and the root system development becomes worse. Its ability to absorb water and nutrients decreases, resulting in the overall production of bamboo shoots deteriorating, and the base diameter and length are greatly reduced.

[0092] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
