Abstract
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.

Embodiment 1
[0018] An insect-resistant slow-release nitrogen fertilizer for grape planting, characterized in that it is made of the following raw materials in parts by weight (Kg): natural zeolite 55, 2mol / L dilute HCl12, 6wt% NaCl solution 165, organic phosphorus agent 1, ammonium sulfate 80 , superphosphate 15, potassium permanganate 5, peat soil 15, seaweed extract 1, medium and trace elements 4, paclobutrazol 0.5, boric acid 5 and appropriate amount of water;
[0019] A preparation method for insect-resistant grape planting slow-release nitrogen fertilizer, characterized in that it comprises the following steps:
[0020] (1) Preliminarily crush the natural zeolite to form a block with a diameter of 6~8cm, and then uniformly put it into a high-temperature kiln at 800~1000°C for 6~8h, and carry out secondary fine crushing after cooling to become a 50~ 60-mesh sieve, and finally wash the granule powder with 2mol / L dilute HCl for 2-3 times;
[0021] (2) Put the granules obtained in (1) i...
