Problems solved by technology

[0003] At present, many plant growth regulators used alone often fail to achieve the desired effect. The disadvantages of single-dose application of plant growth regulators are: the biological activity is relatively single, the growth regulation effect is relatively low, and the usage amount (or use concentration) is relatively large. And generally can only play a role in regulating the growth of crops in a certain growth period

Embodiment 1

[0063] Example 1 Indoor activity bioassay test

[0064] The indoor activity bioassay test adopts the soil cultivation method, and is carried out with reference to the test method for promoting / inhibiting seed germination test in the first part of the "Indoor Bioassay Test Guidelines for Pesticides NY / T2061.1-2011". The specific test method is as follows:

[0065] The experiment was divided into blank control group and test group. The blank control group treated ryegrass with water. The test groups are divided into the first test group, the second test group and the third test group.

[0066] The first test group: a single dose of triacontanol (6 concentrations were set up, respectively 0.2mg / L, 0.5mg / L, 1.0mg / L, 1.5mg / L, 2.0mg / L, 5.0mg / L ) treats ryegrass;

[0067] The second test group: with diethyl hexanoate citrate single agent (9 concentrations are set up, respectively 100mg / L, 80mg / L, 60mg / L, 50mg / L, 40mg / L, 30mg / L, 20mg / L , 10mg / L, 5mg / L) to process ryegrass;

[0109]

[0110]

[0111] The processing flow chart of microemulsion is as follows: figure 1 shown. The specific operation is as follows:

[0112] Add triacontanol, organic solvent, and emulsifier into the reaction kettle according to the formula amount, start stirring, and heat to 50-60°C to fully dissolve triacontanol and emulsifier in the organic solvent to form an oil phase.

[0113] Dissolve antifreeze, diethyl hexanoate citrate, wetting and dispersing agent, and synergist in deionized water according to the formula, heat to 60-80°C, fully stir and dissolve completely, and form a water phase.

[0114] Keep the temperature of the reaction kettle at 60-80°C, slowly add the a...

Embodiment 3

[0115] Example 3 Preparation of 1.1% triacontanol diethyl diethylhexanoate citrate microemulsion

[0116] The formula of 1.1% triacontanol diethyl diethylhexanoate citrate microemulsion is shown in Table 9.

[0117] Table 9 Formula of 1.1% triacontanol diethyl diethylhexanoate citrate microemulsion

[0118]

[0119] According to the processing technology of embodiment 2, microemulsion is prepared.

Abstract

The invention relates to the field of phytochemistry control, in particular to a plant growth regulator combination and an application and a preparation thereof. The plant growth regulator combination is composed of diethyl aminoethyl hexanoate or diethyl aminoethyl hexanoate salt and triacontanol. The plant growth regulator combination has a synergistic effect. The plant growth regulator compound preparation has the functions of facilitating growth, increasing the fruit setting rate and the yield, and improving fruit quality.

Description

technical field [0001] The invention relates to the field of phytochemical control, in particular to a plant growth regulator composition and its application and preparation. Background technique [0002] Plant growth regulators are artificially extracted and synthesized according to the structure, function and action principle of plant hormones. They can change the synthesis, transportation, metabolism and action of hormones in plants, thereby regulating plant growth and physiological functions. A large class of chemical substances. It has been found that the functional substances that can regulate plant growth and development include diethylhexanoate (DA-6), forchlorfenuron, sodium nitrophenolate, auxin, gibberellin, ethylene, cytokinin, abscisic acid, and brassinolide , salicylic acid, jasmonic acid, paclobutrazol and polyamines. Plant growth regulators can promote or inhibit the growth and development of plants at relatively low concentrations. So far, plant growth reg...
