This invention discloses a pesticide reduction and enhancement adjuvant and its preparation method, belonging to the field of pesticide technology. The adjuvant is composed of 7-9 parts potassium oleate, 1-2 parts dipotassium hydrogen phosphate, and 1-2 parts 2-ethylidene-5-phenylvaleric acid. The preparation method involves stirring and mixing the components at room temperature to form a homogeneous solution. When used in combination with chemical pesticides such as triadimefon, carbendazim, and pyraclostrobin, this adjuvant can significantly enhance pesticide efficacy. Even with a 50%-80% reduction in chemical pesticide usage, the control efficacy remains above 90%, effectively reducing pesticide residues and environmental risks. This invention has the advantages of simple composition, low cost, and environmentally friendly process, and is suitable for reducing pesticide use and increasing efficiency in agricultural production.

The invention belongs to the technical field of semiconductor power devices, and provides a variable capacitance diode and a preparation method. The variable capacitance diode comprises an N + substrate, an N-epitaxial layer, a first P + doped region, a second P + doped region, a dielectric layer, a front metal layer and a back metal layer, wherein the first P + doped region is annularly arranged above the N-epitaxial layer; the second P + doped region is circularly arranged above the N-epitaxial layer and is concentric with the first P + doped region, the diameter of the second P + doped region is larger than the outer diameter of the first P + doped region, and the depth of the second P + doped region is smaller than that of the first P + doped region; the first P + doped region and the second P + doped region are formed through two times of injection and annealing, and the injection energy and the injection dosage of the first P + doped region are larger than those of the second P + doped region. The depletion layer is widened along with the increase of voltage, the depletion layer of the second P + doped region and the depletion layer of the first P + doped region tend to be consistent, so that the capacitance reduction effect is obvious, and the capacitance ratio of the variable capacitance diode is effectively increased.
