Embodiment 1

[0029] Contrast experiment of yield of naphthalene acetic acid and naphthalene acetic acid+GR24

[0030] 1. Experimental object: wheat.

[0031] 2. Experimental method: Refer to "Pesticide Indoor Bioassay Test Guidelines NY / T 2061.2-2011" Plant Growth Regulator Part 2: Promoting and Inhibiting Plant Growth Test.

[0032] 3. Statistical analysis of data: DPS6.55 (Duncan) statistical software was used for analysis. The average yield per mu C1 (kg) is calculated according to the test data, and the average yield per mu yield T1 (%) relative to the blank control is calculated.

[0033] 4. Evaluation method: use the Colby formula to obtain the average yield increase rate E1 (%) after theoretical mixing. Compared with the theoretical index E1 (%) obtained by the Colby formula, the actual measured evaluation index T1 (%) after mixing is compared with the theoretical index E1 (%). The actual value is greater than the theoretical value of 12%. Between 0%-12% is additive effect, and t...

[0041] Comparison experiment of the total root area of ​​naphthalene acetic acid and naphthalene acetic acid + GR24

[0042] 1. Experimental object: wheat.

[0043]2. Experimental method: refer to "Pesticide Indoor Bioassay Test Guidelines NY / T 2061.2-2011" Plant Growth Regulator Part 2: Promoting and Inhibiting Plant Growth Test.

[0044] 3. Statistical analysis of data: DPS6.55 (Duncan) statistical software was used for analysis. According to the test data, the average total root area C2 (cm 2 ), relative to the average total root area improvement rate T2 (%) of the blank control.

[0045] 4. Evaluation method: use the Colby formula to obtain the average total root area increase rate E2 (%) after theoretical mixing. Compared with the theoretical index E2 (%) obtained by the Colby formula, the actual measured evaluation index T2 (%) after mixing is the effect of synergy, and the difference between the actual value and the theoretical value is greater than 12%. Between 0%-...

Embodiment 3

[0053] Compound synergistic experiment of zinc oxide

[0054] 1. Experimental object: wheat.

[0055] 2. Experimental method: refer to "Pesticide Indoor Bioassay Test Guidelines NY / T 2061.2-2011" Plant Growth Regulator Part 2: Promoting and Inhibiting Plant Growth Test.

[0056] 3. Statistical analysis of data: DPS6.55 (Duncan) statistical software was used for analysis. According to the test data, the average mu yield C is calculated 1 (kg), relative to the average mu yield increase rate T of the blank control 1 (%); Calculate the average root system total area C according to the test data 2 (cm 2 ), relative to the average total root area improvement rate T of the blank control 2 (%).

[0057] 4. Evaluation method: By comparing the average mu yield increase rate T of each treatment corresponding to the blank 1 (%) and average root system total area improvement rate T 2 (%), to judge whether zinc oxide has the ability to enhance the average yield per mu and the averag...

Abstract

The invention discloses a plant rooting composition, a plant rooting preparation and application of the plant rooting composition. The plant rooting composition is prepared from an active ingredient A, an active ingredient B and a zinc fertilizer, wherein the mass ratio of the active ingredient A to the active ingredient B is (1 to 1000):1, and the mass percent of zinc in the zinc fertilizer is 0.1%-5%; the active ingredient A is selected from one or more of naphthylacetic acid, indoleacetic acid and indolebutyric acid, the active ingredient B is strigolactone or a strigolactone analogue rac-GR24, and the zinc fertilizer is selected from one or more of zinc sulfate, zinc oxide and EDTA zinc. The plant rooting preparation is composed of the plant rooting composition and auxiliary materialsacceptable in agricultural pharmacology. Plant rooting can be promoted, the new root growing speed is increased, the number of lateral roots is increased, therefore, the plant root-shoot ratio is improved, and the crop yield is increased.

Description

technical field [0001] The invention relates to a plant rooting composition, preparation and application thereof, belonging to the technical field of plant rooting agents. Background technique [0002] In agricultural production practice, the cutting of seedlings, transplanting of crop seedlings, and the use of rooting agents are of great significance to promoting the development of plant roots, enhancing the ability of plants to absorb nutrients from the soil, and promoting plant growth. Commonly used rooting agents are naphthaleneacetic acid, indole butyric acid and their mixed preparations. [0003] Among them, naphthaleneacetic acid is a white solid soluble in organic solvents. It is an auxin analog in plant growth regulators and a broad-spectrum plant growth regulator. It can promote cell division and expansion, induce the formation of adventitious roots, but form The root is thick and short; and indolebutyric acid is an endogenous auxin, which can promote cell divisio...
