Compound plant growth regulator and preparation method thereof

Abstract

The invention discloses a compound plant growth regulator. The compound plant growth regulator is wettable powder, and comprises the following raw materials in parts by weight: 0.12-0.17 part of 5-nitroguaiacol sodium salt, 0.3-0.6 part of o-nitrophenol, 0.5-0.7 part of sodium para-nitrophenolate, 0.08-0.12 part of forchlorfenuron, 1-5 parts of DPPA, 8-16 parts of boric acid, 5-10 parts of potassium sulphate, 5-10 parts of zinc sulfate, 15-30 parts of magnesium sulfate, 5-10 parts of a chelating agent, 0.1-0.5 part of aspirin and the balance being white carbon black. According to the compound plant growth regulator, melons and fruits can grow rapidly, gibberellin can be replaced, flowers and fruits can be retained, fruits are large, the quality and the grade of the fruits can be enhanced, the yield is increased, the cost and the toxicity are low, the application is wide, and the effects are good.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a compound plant growth regulator and a preparation method thereof. Background technique [0002] Plant growth regulators have been widely used as agricultural and forestry chemicals that can increase crop yield and improve quality. But in actual use, there are still some problems. If gibberellin is applied to fruit trees, it can preserve flowers, preserve fruit, expand fruit and increase yield, but at the same time produce fruit with thick skin, thick skin, high acidity, poor gloss, and uneven fruit size, which will affect the quality of the fruit. Fufenfenuron is expensive, high in cost, poor in dispersibility, poor in permeability, prone to deformed fruit, improper application method, and phytotoxicity. In addition, the present plant growth regulators are often used alone in single doses, and the compound type is less. Sometimes in order to produce consistent effects, the single d...

Problems solved by technology

If gibberellin is applied to fruit trees, it can preserve flowers, preserve fruit, expand fruit and increase yield, but at the same time produce fruit, thick skin, thick skin, high acidity, poor gloss, and uneven fruit size, which will affect the quality of the fruit.

High price, high cost, poor dispersibility, poor permeability, easy to produce malformed fruit, improper application method, and phytotoxicity

In addition, the present plant growth regulators are often used alone in single doses, and the compound type is less. Sometimes in order to produce consistent effects, the single doses are also directly mixed together for use. The efficacy of plant growth regulators will also increase the cost of use and affect fruit quality
