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 sustained release function and a preparation method thereof. Background technique: [0002] Paclobutrazol is a triazole plant growth retardant, which exerts a wide range of physiological effects by interfering with and hindering the biosynthesis of endogenous gibberellin. Improve plant type, reduce lodging; promote tillering; promote flower bud formation and control shoots and fruit protection, etc. It is currently the most widely used plant growth regulator. However, in actual production and application, the drug injury of paclobutrazol is often caused by too fast and too strong. At the same time, for areas with abundant rain and heat, vigorous crops often require repeated use of paclobutrazol agents. Invention content: [0003] The object of the present invention is to overcome above-mentioned def...
