Problems solved by technology

Manual sprouting needs to be carried out 4-6 times. On the one hand, manual sprouting is difficult to carry out thoroughly, and consumes a lot of manpower; Insufficient accumulation of substances delays harvesting and reduces the quality of tobacco leaves
Ultimately lead to less than ideal yield and quality

Embodiment 1

[0032] wettable powder powder

[0033]

[0034] The preparation method of the strigolactone synthetic analogue GR24.6-benzylaminopurine wettable powder is: after dissolving the acetone of the same weight as the strigolactone synthetic analogue GR24, absorbing it with white carbon black, After removing acetone at 40°C, it can be prepared by mixing with 6-benzylaminopurine, polycarboxylate, fatty alcohol polyoxyethylene ether, and diatomaceous earth evenly and airflow pulverization.

Embodiment 2

[0036] water dispersible granules

[0037]

[0038] The preparation method of the strigolactone artificially synthesized analog GR24.6-benzylaminopurine water-dispersible granule is: after dissolving the acetone of the same weight of the strigolactone artificially synthesized analog GR24, absorbing it with white carbon black, After removing acetone at 40°C, mix with 6-benzylaminopurine, polycarboxylate, sodium lignin sulfonate, corn starch, and diatomaceous earth, and then mix it with 2-5% of It can be obtained by kneading, granulating and drying after wetting with atomized water.

Embodiment 3

[0040] Dispersible oil suspension

[0041]

[0042]

[0043] The preparation method of the strigolactone synthetic analog GR24·6-benzylaminopurine dispersible oil suspension concentrate is as follows: synthetic strigolactone analog GR24, 6-benzylaminopurine, BREAK-THRUDA646, BREAK -THRUSD260, fumed silica A-974, and methyl oleate are sanded until the D98 is less than 3um, and the material is discharged for packaging.

Abstract

The invention discloses a plant growth regulating composition, preparation and application thereof. The composition comprises: active ingredient A and active ingredient B; the active ingredient A is a strigolactone plant growth regulator, and the active ingredient The component B is 6-benzylaminopurine; the weight ratio of the active component A to the active component B is 1:1-100; it can regulate the growth of tobacco leaves, reduce the germination and growth of tobacco axillary buds, and improve the yield and quality of tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a plant growth regulating composition, preparation and application thereof. Background technique [0002] Tobacco is an economic crop for leaves. Topping prevents its reproductive growth and can promote the enlargement of leaves, especially for the full development and maturity of middle and upper leaves, thereby improving the yield and quality of tobacco leaves. However, while topping, the axillary buds of the tobacco plant also grow vigorously thereupon, and every leaf axil of the tobacco plant can regenerate 2-3 or more axillary buds. If it is allowed to grow and compete with the leaves for nutrients and water, it will consume a lot of nutrients, affect the growth and fullness of the main stem leaves, and cause the leaves in the middle and lower parts of the tobacco plant to be insufficient, light in weight, less oily, poor in elasticity, taste and aroma Both are reduced; ...
