[0020] The present invention is a multifunctional slow-release fertilizer additive, which is composed of the following raw materials in parts by weight:

[0021] Dicyandiamide: hydroquinone: lignin: sodium selenite: auxiliary material=10:5:10:0.3:74.7.

[0022] Auxiliary material of the present invention is to be made of following raw material by weight ratio:

[0023] Zeolite powder: humic acid: manganese mud = 2:1:0.5

[0024] The production process of the present invention is simple and easy to implement. Specifically, according to the above proportions, 2 kg of zeolite powder, 1 kg of humic acid, and 0.5 kg of manganese mud are mixed and stirred evenly, and the prepared auxiliary materials are used for later use.

[0025] Get 10 kilograms of dicyandiamide, 5 kilograms of hydroquinones, 10 kilograms of lignin, 0.3 kilograms of sodium selenite according to the above ratio, get 74.7 kilograms of above-mentioned spare auxiliary materials, grind to 80 orders again, mix by prop...

Embodiment 2

[0029] The present invention is a multifunctional slow-release fertilizer additive, which is composed of the following raw materials in parts by weight:

[0030] Dicyandiamide: hydroquinone: lignin: sodium selenite: auxiliary material=20:6:12:0.5:61.5.

[0031] Auxiliary material of the present invention is to be made of following raw material by weight ratio:

Abstract

The invention relates to the technical field of fertilizer additives, particularly to a multifunctional slow-release fertilizer additive which comprises the following raw materials in parts by weight: 10-30 parts of dicyandiamide, 5-15 parts of quinhydrone, 10-20 parts of lignin, 0.3-1 part of sodium selenite and 34-74.7 parts of auxiliary material. When in use, the raw materials are proportionally added into an ordinary fertilizer and a compound fertilizer and then mixed to prepare a multifunctional slow-release fertilizer, the preparation method is quite simple, the effective period of the fertilizer can be prolonged to 90-120 days, the utilization ratio of the fertilizer is improved by 20-30 percent, and the invention increases the yield and the income, saves the fertilizer and the labor, achieves one-time fertilization, saves resources and reduces environment pollution, so that the content of biological selenium in crops is increased by 5-10 times, the content of multiple amino acids is increased, and the contents of lysine and cystine thereof are respectively increased by 30 percent and 50 percent. Moreover, people can safely and effectively carry out biological selenium supplement, and the efficacy of preventing and treating diseases and strengthening bodies is achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizer additives, in particular to a multifunctional slow-release fertilizer additive. Background technique [0002] At present, with the gradual increase of population, the reduction of cultivated land and the continuous improvement of living standards in our country, it is required that agriculture should also continuously increase production and improve product quality. my country is a big country in the production and use of chemical fertilizers, but the product quality needs to be further improved. Its main problem is that the fertilizer effect period of the fertilizer is short, the utilization rate is low, and the function is single. Among them, the fertilization period of nitrogen fertilizer is only 30-50 days, and the fertilizer period of crops is generally 90-120 days, and its utilization rate is only 30%-40%, and the other 60%-70% are lost in the atmosphere and water, resulting in Signific...
