Description

Plant growth regulator composition

Technical field

The present invention relates to a kind of plant growth regulator composition and uses thereof, especially a kind of plant growth regulator composition that contains maleic hydrazide is used to regulate the application and the composition composition thereof of cultivated plant growth.

Background technology

In recent years; China's plant growth regulator is used area and is constantly enlarged, and the output of plant growth regulator and consumption are also improving year by year, though the plant growth regulator of single variety is fine to the regulating effect in some crop field; But because the application of single plant growth regulator is narrower; Crop-selective is stronger, and effect is undesirable, and it is dangerous also some crop to be existed potential poisoning simultaneously.Therefore, use the exploitation with complex preparation with between the plant growth regulator, become one of main developing direction of plant growth regulator industry; Use with and the composite decapacitation of plant growth regulator enlarge adjustable range; Improve outside drug effect and the selectivity, can also reduce the dosage of plant growth regulator, reduce drug cost relatively; And the longevity of residure of shortening medicament; Avoid poisoning, make crop safety, thereby the composite and application of plant growth regulator has become the main developing direction of plant growth regulator industry developmental research.
