Embodiment 1

[0021] DCD 68kg, ATC 20kg, NBPT 9kg, S-80 3kg. After mixing the above four materials, add 150kg of water, heat to 95°C, and stir for 30 minutes to form an aqueous solution, which becomes a water-based compound fertilizer synergist. Mainly used in the production of ammonium nitrogen as the main nitrogen source fertilizer processing.

Embodiment 2

[0023] NBPT 20kg, DCD 57kg, ATC 20kg, S-80 3kg, mixed with 100kg of water, heated, dissolved at 95°C, stirred for 30 minutes to form an aqueous solution, which becomes another water-based compound fertilizer synergist. It is mainly suitable for high-concentration compound fertilizers with amide nitrogen as the main nitrogen source. It is more effective in controlling the volatilization loss of ammonia, and the fertilizer has a longer validity period after application.

Embodiment 3

[0025] Add NBPT1.5kg, DCD4.7kg, ATC2.0kg, S-803.0kg, add water 14.0kg, heat and stir at 95°C for 30 minutes, and spray it on 3.0 tons of 26:12:8 granular compound fertilizer with a high-pressure pump , forming a special fertilizer for corn with long-acting functions. After planting corn, the fertilizer is valid for 120 days, which is 8.6% higher than that of the same nutrient fertilizer without additives, and the yield per mu is increased by 48 kg.

Abstract

The invention relates to a sustained release drug used by a fertilizer during a film-forming cement mortar blowing processing procedure, in particular to a water-base synergistic agent used for a compound fertilizer as well as preparation and application thereof. The water-base synergistic agent includes DCD, ATC, NBPT, S-80 and water; calculated by weight percentage, the weight ratios of the DCD, the ATC, the NBPT and the S-80 are 50 to 70 : 15 to 30 : 9 to 20 : 3 to 4; the ratio of water to the gross weight of the four materials is 1 : 1 to 1.5, wherein, the DCD id dicyandiamide, the ATC is 4-aminotriazole, the NBPT is N-(normal-butyl) thiophosphoryl triamine and the S-80 is dehydrated sorbitan fatty glyceride. The invention avoids applying an organic solvent, thus reducing the cost and improving the effectiveness of the fertilizer.

Description

technical field [0001] The invention relates to a long-acting agent used in the process of film-forming and spraying of fertilizers, in particular to a water-based synergist used in compound fertilizers and its preparation and application. Background technique [0002] Synergists mainly refer to a class of substances based on inhibitors, including urease inhibitors and nitrification inhibitors. There are more than 120 kinds of inhibitor materials that have been proven effective, but those that are actually used as commodities and applied to agricultural production There are only a few. Among them are Agrotain and N-Serve from the United States, Ammonium No. 1, NAM (long-acting compound fertilizer additive) and other products in China. [0003] The two products in the United States are both liquid, which is conducive to application, while the products in my country are all solid powder substances. At present, the long-acting agent used in production is powder, which needs t...
