Liquid pesticide fertilizer for preventing nematode and promoting growth as well as preparation method and application of liquid pesticide fertilizer

Abstract

The invention relates to a liquid pesticide fertilizer for preventing nematode and promoting growth as well as a preparation method and application thereof. The liquid medical fertilizer comprises 500-700 g / L of an abamectin-fosthiazate microcapsule suspending agent, 40-100 g / L of monopotassium phosphate, 25-70 g / L of potassium hydroxide, 50-100 g / L of monoammonium phosphate, 100-200 g / L of urea, 30-80 g / L of potassium nitrate, 2-10 g / L of ferrous citrate, 5-15 g / L of chelated zinc, 3-10 g / L of boric acid, 50-100 g / L of humic acid, 20-100 g / L of a soil loosening agent, 3-10 g / L of polyaspartic acid, 5-25 g / L of an anti-freezing agent, 0.5-5.0 g / L of a stress-resistant synergistic factor, 10-60 g / L of an emulsifier and 2-10 g / L of a dispersant. The liquid pesticide fertilizer provided by the invention has dual functions of nematode prevention and growth promotion, not only can prevent and treat root-knot nematode and protect crop root systems, but also contains organic and inorganic nutrients, provides growth elements for crops and promotes root system growth, and effectively solves the problem that the function of nematode prevention by pesticide and nematode prevention by fertilizer is single.

Description

technical field [0001] The invention belongs to the technical field of liquid fertilizer industry, and in particular relates to a liquid medicinal fertilizer for preventing nematodes and promoting growth, a preparation method and application thereof. Background technique [0002] Abamectin is a class of sixteen-membered macrolide compounds with insecticidal, acaricidal and nematicidal activities. It is a neurotoxin that acts on insect neuronal synapses or neuromuscular synapses. Main effect, less contact and systemic effects, paralysis, refusal to feed, and death of insects by blocking nerve impulse conduction. The B1a isomer and B2a isomer of abamectin have high biological activity against crop root-knot nematodes, but due to the large organic carbon coefficient of the abamectin compound molecule, it is difficult to migrate in the soil due to its tight combination with organic matter , so in practical application the bioavailability of abamectin is low, and the control eff...

AI Technical Summary

Problems solved by technology

The content of nitrogen, phosphorus and potassium per liter of the liquid fertilizer produced by the invention is increased to 460g, and the content of humic acid reaches 45g. There is no precipitation, and it is not easy to block the pipeline. growth, but not effective against root-knot nematodes
