Release-controlled medicine fertilizer composition and preparation method thereof

Abstract

The invention provides a release-controlled medicine fertilizer composition and a preparation method thereof. The medicine fertilizer composition is prepared from the following raw materials in percentage: 5 to 30 percent of weeding agents, 5 to 40 percent of fertilizers, 10 to 30 percent of surfactants, 0.5 to 3 percent of photoinitiators, 5 to 20 percent of prepolymers and the balance of solvents. The medicine fertilizer composition has the advantages that the medicine does not need to be prepared into a microcapsule preparation; and through the addition of the specific photoinitiator to bemixed with the prepolymers, medicine fertilizer can perform spontaneous reaction under the illumination condition after spraying use so as to form the medicine fertilizer composition with a slow-release effect. The medicine fertilizer active ingredient stability and effect-lasting period are improved.

Description

technical field

[0001] The invention relates to a pesticide and fertilizer composition, belongs to the technical field of medicinal fertilizers, in particular to a controlled-release medicinal fertilizer composition and its application. Background technique

[0002] With the development of the economy and the improvement of people's living standards, the area of ​​non-cultivated land in citrus orchards, peach orchards, vineyards and other orchards is increasing, and weeding on non-cultivated land has become one of the important aspects of herbicide use. Most of the weeding in orchards uses herbicides such as glyphosate and glufosinate-ammonium. Unlike pesticides or fungicides, herbicides are more commonly used in wasteland or woodland, and usually do not require additional fertilizers after use. With the increase of orchard planting area, the demand for the use of herbicides in orchards is gradually increasing. In addition to weeding needs, orchards also need to supplement...
