Embodiment 1

[0085] Embodiment 1: Preparation of seaweed synergistic urea of ​​the present invention

[0086] The preparation steps are as follows:

[0087] (1) After the kelp raw material is pulverized by crushing equipment, add 100 parts by weight of cornmeal and 30 parts by weight of sugar to 800 parts by weight of natural seaweed raw material powder, and after the mixture is stirred evenly, the water content of the mixture is adjusted to 30% by weight with water , then adjust its pH to 6 with 2N aqueous sodium hydroxide solution, so as to obtain a natural seaweed fermentation material;

[0088] (2) 0.1 weight part of EM flora fermented liquid produced by Jilin Great Wall Agricultural Machinery Biotechnology Co., Ltd. and 0.1 weight part of sucrose are added to 0.5 weight part of water, and after mixing, put into an airtight container and store for 20 hours, so a kind of EM fermentation flora stock solution;

[0089] (3) Use water to dilute the EM fermented flora stock solution prepar...

Abstract

The invention relates to algae-enhanced urea and a production method thereof. According to the invention, a fertilizer is produced through steps that: natural algae and urea are adopted as raw materials; algae is subject to microbe fermentation, and is subject to processes such as extraction and press-filtration, such that an algae enhancing liquid is prepared; molten urea solution and the algae enhancing liquid are granulated in an urea granulating tower, such that the algae-enhanced urea provided by the invention is obtained. With the algae-enhanced urea, soil urease activity can be substantially inhibited. The algae-enhanced urea has an enhanced fertilizer releasing-retarding effect. With the algae-enhanced urea, a utilization rate of fertilizer is improved by 5-10%, and agricultural cultivation can be simplified; nutrient loss can be reduced; secondary pollution can be avoided; and agricultural production cost can be reduced. The algae-enhanced urea is advantaged in wide raw material source, convenient transportation, and convenient application. With the algae-enhanced urea, mechanical working can easily be carried out. Therefore, the algae-enhanced urea has a wide prospect in production.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical fertilizers. More specifically, the present invention relates to a seaweed synergistic urea, a production method of the seaweed synergistic urea, and a use of the seaweed synergistic urea. 【Background technique】 [0002] Urea is also known as carbonamide, carbonamide, urea. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen with the chemical formula CO(NH 2 ) 2 . Appearance is white crystal or powder. Urea is a high-concentration nitrogen fertilizer, which is a neutral quick-acting fertilizer, and can be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, but if the temperature is too high in granulation, a small amount of biuret will be produced, which has an inhibitory effect on crops. my country stipulates that the content of urea biuret for fertilizers should be less than 0.5%. Urea is an organic nitrogen fertilizer th...
