Plant growth regulator composition, preparation method and application thereof
A technology for plant growth regulators and growth regulators, applied in the direction of plant growth regulators, plant growth regulators, botany equipment and methods, etc., can solve the problem that the increase of vitamin C content is not particularly obvious, and the effect of increasing organic fertilizer is not enough Especially stable, organic fertilizer is not fully decomposed, etc., to achieve the effect of improving the utilization rate of liquid medicine, promoting the development of crop root system, and reducing losses

Example Embodiment
[0053] Example 1: Indoor pot experiment
[0054] Test method: Refer to "Pesticide Indoor Bioassay Test Guidelines NY / T2061.2-2011" Plant Growth Regulator Part 2: Promoting Plant Growth Test Stem and Leaf Spray.
[0055] Using different proportions, different content mixtures and single-agent treatment crops, by measuring the vitamin C content (mg / 100g) grape product quality indicators in the late crop and the blank control area to measure the rationality of the mixing.
[0056] According to the mass ratio in the table, 2-(acetoxy)benzoic acid (A) and methyl jasmonate (B) are uniformly mixed and completely dissolved in ethylene glycol to form the regulator composition.
[0057] Effect evaluation method:
[0058] Calculated as follows:
[0059] Growth rate: E = (test data-clear water control) / clear water control *100%
[0060] Inhibition rate: E = (clear water control-test data) / clear water control * 100%
[0061] Theoretical value E0: E0=X+Y-X*Y / 100 (Gowing formula)
[0062] Among them: X ...
Example Embodiment
[0073] Example 2: Field efficacy experiment
[0074] (1) Subject: Kyoho grape
[0075] (2) Experimental purpose: to regulate plant growth and increase the vitamin C content of grapes;
[0076] (3) The test site is Pingquan Town, Jianyang City;
[0077] (4) Application method, application period and dosage: prepare the corresponding samples according to the composition ratio in Table 2, and then spray the whole plant evenly, focusing on the ears; according to the growth characteristics of the grapes, each during the grape expansion period and the color change period Spray the medicine once, based on spraying the same amount of liquid medicine (the effective ingredient spraying concentration is 0.3g / L, the water consumption per mu is 30 kg), 16 treatments, 4 repetitions, a total of 64 plots. Each plot has at least 16 grapes. Use random block arrangement, try to keep the original conditions of each cell consistent. Spraying was carried out during the fruit swelling period and the colo...
Example Embodiment
[0083] Example 3: Field efficacy experiment
[0084] (1) Subject: Red Fuji Apple
[0085] (2) Experimental purpose: to regulate plant growth and increase the vitamin C content of apples;
[0086] (3) Test site: Shewobo Town, Qixia City, Shandong Province;
[0087] (4) Application method, application period and dosage: prepare the corresponding sample according to the composition ratio in Table 4, and then spray the whole plant uniformly; according to the growth characteristics of the apple, spray once in the apple expansion period and the color change period. On the basis of spraying the same amount of liquid medicine (the effective ingredient spraying concentration is 0.3g / L, the water consumption per mu is 30 kg), 16 treatments are set up with 4 repetitions, a total of 64 plots. Each plot has at least 10 apples. Use random block arrangement, try to keep the original conditions of each cell consistent. Spraying was carried out during the fruit swelling period and the color changin...
