Description

Technical Field

[0001] The present invention relates to the technical field of plant growth regulators, and particularly to the application of a compound in plant rooting and a plant rooting composition. Background Art

[0002] Plant growth regulators are chemically synthesized (or natural ones extracted from microorganisms) chemical substances that regulate the growth and development of plants and have chemical properties similar to plant hormones. Roots are the vegetative organs of plants. The development and function of plant roots are closely related to the life activities of plants. Roots play important roles at all stages of plant growth. Therefore, rooting agents are an important type of plant growth regulator.

[0003] Rooting agents belong to auxin compounds in the category of plant growth regulator promoters. In vegetable production applications, there are multiple components such as indoleacetic acid, indolebutyric acid, naphthylacetic acid, Yugen Sheng, br rooting agent, sodium nitrophenolate, etc. Their functions are to maintain apical dominance in plants, induce the transport of assimilates to products (fruits), and promote plant rooting, etc. They are mainly suitable for use in the seedling raising, seedling separation, transplanting, and planting stages of economic crops such as fruits, vegetables, cotton, seedlings, flowers, and medicinal materials, with remarkable effects and high cost performance.

[0004] The patent with publication number CN105884528A and name "A Nutritional Spray for Promoting the Rapid Rooting of Vegetable Seedlings and Its Preparation Method" discloses a nutritional spray for promoting the rapid rooting of vegetable seedlings and its preparation method, which is made from the following raw materials in parts by weight: magnesium sulfate heptahydrate, gypsum powder, sesame oil residue, potassium ore powder, indolebutyric acid, cytokinin, chitin, urea, peanut shell powder, sodium metasilicate, humic acid powder, potassium nitrate, fish bone powder, diammonium phosphate, rice husk, fermentation bacterial mass, and an appropriate amount of water. The plant growth hormones contained in the above technical solution can promote the rooting and rapid growth of vegetables, and at the same time, through the fermentation of plant endophytes, an insect resistance effect is produced, but the required fermentation process is complex, and the effects of indolebutyric acid and cytokinin are conventional.

[0005] However, modern agriculture has higher and higher requirements for the growth rate, yield, and quality of crops. Therefore, it is necessary to study new rooting compounds suitable for the development of modern agriculture. Summary of the Invention

[0006] In view of this, the present invention provides the application of a compound in plant rooting and a plant rooting composition, and uses a new rooting compound to achieve the purpose of promoting plant root length and weight gain.

[0007] To achieve the above object, the present invention provides a plant rooting compound, and the compound is 8 - quinolyloxyacetic acid.

[0008] Optionally, the mass concentration range of the 8 - quinolinoxyacetic acid is 0.1 - 200 ppm.

[0009] To achieve the above object, the present invention provides a plant rooting composition, which comprises 8 - quinolinoxyacetic acid and a complexing agent.

[0010] Optionally, the mass ratio of the 8 - quinolinoxyacetic acid to the complexing agent is 1:0.1 - 100.

[0011] Optionally, it is one or a combination of two or more of 2 - (3,4 - dichlorophenoxy)triethylamine, resveratrol, pyrroloquinoline quinone, diphenylurea disulfonate, amino acid, half - leaf element, naphthylacetic acid salt, indolebutyric acid salt, indoleacetic acid salt and naphthylacetamide.

[0015] Optionally, the composition is 8 - quinolinoxyacetic acid and resveratrol.

[0016] Optionally, the mass ratio of the 8 - quinolinoxyacetic acid to the resveratrol is 1:2.

[0017] The resveratrol used in the present invention as a complexing agent with 8 - quinolinoxyacetic acid, on the one hand, enhances the rooting effect of plants, and on the other hand, avoids problems such as root rot of plants affected by the environment.

[0031] Comparative Example 2 Use clean water as a rooting agent for plants.

[0032] Comparative test Test method: select green vegetables with consistent growth within a certain range, divide them into 9 areas, and use A, B, C, D, E, F, G, H, I, i.e., Examples 1, 2, 3, 4, 5, 6, 7 and Comparative Examples 1 and 2 for spraying treatment respectively. After 7 days of medication, randomly select 3 green vegetables from each area, remove the soil and substrate at the roots, and measure the root growth. After 25 days of medication, randomly select 5 green vegetables from each area to measure the yield.

[0033] The formula of the liquid medicine is shown in Table 1, and the data of root length, plant height, plant width, fresh weight, etc. are shown in Table 2 and Figure 1 , 2 .

[0034] Table 1 Liquid formula

[0035] Table 2 Related index data of green vegetables after using each liquid

[0036] Note: If the superscript letters of the same index are the same, there is no significant difference; if different, there is a significant difference.

[0037] Taking Comparative Example 2 as the benchmark, the promotion rates of various indicators of Examples 1-7 and Comparative Example 1 were calculated to obtain Table 3, and the analysis shows Figure 3 、 4 、5、6.

[0040] Comparing Example 2 with Example 1, it can be seen that when 8-quinolyloxyacetic acid is used alone, the root length promotion rate, plant height promotion rate and plant width promotion rate at a concentration of 50 ppm are all higher than those at a concentration of 25 ppm. Comparing Example 2 with Examples 3-7, it can be seen that the combination of 8-quinolyloxyacetic acid and the compound agent has different degrees of increase and decrease in the root length promotion rate, plant height promotion rate and plant width promotion rate, but they are all higher than those of the comparative examples. Comparing Examples 1-7 with the comparative examples, there are different degrees of advantages in the root length promotion rate, plant height promotion rate and plant width promotion rate.

[0041] In summary, the plant rooting compound and composition used in the present invention have obvious promotion effects on green vegetables, are beneficial to the rooting growth of green vegetables, and also have an enhancing effect on the plant height and plant width of green vegetables, achieving the effects of promoting the growth of green vegetables, making them big and vigorous, and increasing production.

[0042] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
