Pest-resistant grape planting slow-release nitrogen fertilizer and preparation method thereof

Abstract

The invention discloses a pest-resistant grape planting slow-release nitrogen fertilizer and a preparation method thereof. The nitrogen fertilizer is prepared from the following raw materials in parts by weight: natural zeolite, 2mol / L diluted HCl, a 6wt% NaCl solution, an organic phosphorus agent, ammonium sulfate, calcium superphosphate, potassium hypermanganate, peat soil, a seaweed extract solution, secondary and trace elements, paclobutrazol, boric acid, and a proper amount of water. The added seaweed extract solution can improve the soil granular structure, improve soil fertility, and repair soil hardening and acidification problems; the organic phosphorus agent has contact poison and stomach toxicity as well as fumigation desinsection action; at the same time, a great amount of secondary and trace elements and ammonium nitrogen are added to perform adsorption with zeolite granules, so that the action time of a disinfectant and an activating agent is prolonged, and the diseases and insect pests are prevented for a long term; and a certain amount of boric acid is added to favorably improve soil pH.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an insect-resistant slow-release nitrogen fertilizer for grape planting and a preparation method thereof. Background technique [0002] Zeolite is the general term for zeolite minerals. So far, more than 40 kinds of natural zeolites have been discovered in the world. The more common ones are analcite, clinoptilolite, laurelite, erionite, chabazite, and mordenite. Zeolites are mainly composed of SiO 2 、Al 2 o 3 、H 2 A silicate mineral composed of four parts of O, alkali metal and alkaline earth metal ions, in which silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons constitute the three-dimensional space frame structure of zeolite, and alkali metals, alkaline earth metals and water molecules are loosely and easily combined. Substitution, so that zeolite has special application performance - adsorption, ion exchange and so on. [0003] Agriculture and ...

Problems solved by technology

[0003] Agriculture and planting have now become an important indicator of a country's productivity. In order to improve production efficiency, large-scale agriculture and planting have accelerated production, which often results in the lack of nutrients in the planting land. It is inevitable to abuse chemical fertilizers to increase production. A large amount of fertilizers Using it can indeed increase the yield, but the fertilizer cannot be fully utilized within the time of planting. According to data, more than 30% of the fertilizer components are washed into the soil and rivers by rain, causing serious pollution.
