Problems solved by technology

[0007] However, in the traditional agricultural production technology, the above-mentioned fertilizers and pesticides are used separately, and the practice of using pesticides and fertilizers twice or more increases the labor intensity and times of labor of farmers, which is not conducive to agricultural development.
[0008] Combining emamectin benzoate and cyfluthrin with fertilizers to make medicinal fertilizer granules and its application has not been reported

Embodiment Construction

[0033] Table three, several alternative concentrated release process conditions (the active ingredients of pesticides are emamectin benzoate and cyfluthrin).

[0034]

[0035]

[0036]Utilize the test conclusion of Table 3, under this combined process level, design the controlled-release pesticide composition of the present invention, then mix the obtained controlled-release pesticide compositions of several different controlled-release time periods with the fertilizer carrier to obtain multiple The controlled-release medicine fertilizer granules in the time stage, based on the total weight of the medicine fertilizer granules, contain 5% to 45% of nitrogen, 1% to 15% of phosphorus, 1% to 20% of potassium, and 0% to 2% of zinc. %, boron element 0%~2%, manganese element 0%~2%, molybdenum element 0%~2%, copper element 0%~2%, emamectin benzoate 0.01%~10%; Cyfluthrin 0.01% ~ 10%, solvent 0.01% ~ 20%, capsule wall material 0.01% ~ 20%, protective glue 0.01% ~ 20%, emulsifier 0...

Abstract

The invention relates to controlled-release pesticide fertilizer granules which consist of fertilizer components, a controlled-release pesticide composition, a controlled-release agent, an attractant, a dispersion additive and packing, wherein the fertilizer components are prepared by mixing one or more of nitrogen element, phosphorus element, potassium element, zinc element, boron element, manganese element, molybdenum element and copper element; the controlled-release pesticide composition consists of methylamino abamectin benzoate, cyfluthrin, a solvent, a capsule wall material, a protecting adhesive, an emulsifier, a dispersing agent and deionized water. Not only are the granules used as both fertilizers and pesticide, but also the pesticide controlled-release technique is applied to the granules, and the effective prevention and control on soil insects and nematode in different key growth periods of crops are achieved.

Description

technical field [0001] The invention relates to the technology of medicinal fertilizer used in farmland, in particular to a controlled-release medicinal fertilizer granule containing insecticide and compound fertilizer, its preparation method and application. Background technique [0002] Essential macroelements for plant growth and development include carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and potassium (K). Nitrogen is a constituent of chlorophyll. Chlorophyll is an indispensable substance for photosynthesis of higher green plants. Phosphorus is a participant in various metabolic processes in plants, such as the transportation of carbohydrates, the synthesis of sucrose, starch and polysaccharide compounds; phosphorus can improve the ability of plants to resist drought, cold and other stresses and adapt to external environmental conditions. Potassium can improve the absorption and utilization of nitrogen by plants, and can enhance the stress r...
