Embodiment 1

[0022] The Paclobutrazol microcapsule suspension preparation with sustained-release function in Example 1 is composed of the following components based on 100 parts by weight:

[0023] Polytoluene-2,4-diisocyanate 10 parts

[0024] Ethylenediamine 4 parts

[0025] Paclobutrazol 5 parts

[0026] Alkylphenol polyoxyethylene ether 11 parts

[0027] 70 parts of water,

[0028] The preparation method of the preparation of Example 1 is to proportion the ingredients. Stir the polytoluene-2,4-diisocyanate and ethylenediamine at a speed of 150r / min for 1 hour, and put the paclobutrazol into the stirred polytoluene-2,4 —Diisohydrogen acid ester, ethylenediamine, under 35℃±5℃ temperature and normal pressure, stirred and reacted at 200r / min speed for 1 hour to prepare capsule-capsule core complex, and then add alkyl Phenol polyoxyethylene ether is multidimensionally emulsified for 0.5 hours, and finally added to water. In the water phase, the micro-emulsification is continued for 2 hours under the...

Embodiment 2

[0030] The Paclobutrazol microcapsule suspension preparation with sustained-release function in Example 2 is composed of the following components based on 100 parts by weight:

[0031] Carboxymethyl cellulose 15 parts

[0032] 7 parts of diethylene triamine

[0033] Paclobutrazol 20 parts

[0034] Alkyl polyglycoside 11 parts

[0035] 47 parts of water

[0036] The preparation method of the preparation of Example 2 is to proportion the ingredients. Stir the carboxymethyl cellulose and diethylene triamine for 1.5 hours at a rotating speed of 100r / min, and put the paclobutrazol into the stirred hydroxymethyl cellulose, In diethylene triamine, at 45℃±5℃, under normal pressure, 1200r / min stirring and reacting for 1 hour, the capsule membrane-capsule core complex is prepared, and then the alkyl polyglycoside is added for multidimensional emulsification for 0.5 hours. Finally, add water, continue to emulsify for 2 hours under stirring conditions of 500r / min in the water phase, check the part...

Embodiment 3

[0038] In Example 3, the paclobutrazol microcapsule suspension preparation with sustained-release function is composed of the following components based on 100 parts by weight:

[0039] 20 parts of polyvinylpyrrolidone

[0040] 10 parts of polyethylene glycol

[0041] Paclobutrazol 40 parts

[0042] Quaternary Ammonium Glucoside 8 parts

[0043] 22 parts water

[0044] The preparation method of the preparation of Example 3 is to proportion the ingredients. Stir the polyethylene glycol and polyvinylpyrrolidone at a speed of 200r / min for 1 hour, and put the paclobutrazol into the stirred polyethylene glycol and polyvinylpyrrolidone. In the medium, under 65℃±5℃ temperature and normal pressure, 1200r / min stirring and reacting for 2 hours, the capsule core complex is prepared, and the quaternary ammonium glucoside is added for multidimensional emulsification for 1 hour, and finally added to water, in the water phase The emulsification is continued for 3 hours under the stirring condition of...

Abstract

The invention provides a paclobutrazol micro-capsule suspension preparation provided with sustained-release function, which includes the following components according to 100 parts by weight: 10 to 30 parts of film-forming materials, 5 to 40 parts of paclobutrazol, 5 to 10 parts of emulsifying agent and the rest parts of water. The potency of the suspension preparation is more moderate, the potency releases slower and lasts long, thus ensuring the adjustment of steady growth of plants and having the sustained-release function. The invention also provides a preparation method of the paclobutrazol micro-capsule suspension preparation.

Description

Technical field: [0001] The invention relates to a plant growth regulator paclobutrazol preparation, in particular to a paclobutrazol microcapsule suspension preparation with slow-release function and a preparation method thereof. Background technique: [0002] Paclobutrazol is a triazole plant growth retardant. It exerts its extensive physiological effects by interfering with and hindering the biosynthesis of endogenous gibberellin. It has the advantage of inhibiting the top of the plant and promoting the growth of lateral buds; inhibiting stem elongation, shortening internodes, Improve plant shape, reduce lodging; promote tillering; promote the formation of flower buds and control shoots and preserve fruit. It is currently the most widely used plant growth regulator. However, in actual production and application, the effect of paclobutrazol tends to be too fast or too violent, leading to phytotoxicity. At the same time, in areas with abundant rain and heat, the growing crops o...
