Problems solved by technology

The economic loss caused by the low utilization rate of nitrogen in the season is also very huge. Therefore, it is of great significance to study how to reduce heavy metal pollution, improve the soil, and increase the utilization rate of nitrogen in fertilizers.
[0003] At present, there are many researches on fertilizer synergists in our country, but at the same time, there are few researches that can reduce heavy metal pollution, improve soil, and increase nitrogen utilization rate in fertilizers.

preparation example Construction

[0027] The preparation method of the fertilizer additives described in the present application is well known to those skilled in the art, that is, mixing various components uniformly.

[0028] The present invention also provides a fertilizer, which includes the fertilizer additive described in the above scheme of the present application. As a preferred solution, the content of fertilizer additives in the fertilizer is preferably 1wt% to 6wt%, and the balance is common fertilizer; the common fertilizer can be urea, compound (combined) fertilizer, organic-inorganic fertilizer or high tower complex Mix (compound) fertilizer.

[0029] The invention provides a fertilizer additive, which is composed of biomass charcoal powder, slow-release agent, polymerized amino acid, soil structure improver, bioactive agent, composite trace elements, modified starch and modified attapulgite powder, by adding the above components and adjust their content, so that fertilizer additives can reduce h...

Embodiment 1

[0034]50wt% of biochar powder, 10wt% of dicyandiamide, 10wt% of polymeric amino acid (polyglutamic acid, polyaspartic acid molar ratio is about 1:1), 0.2wt% of bioactive agent, 4.8 Wt% chitosan, 5wt% PAM, 5wt% modified starch, 10wt% attapulgite and 5wt% composite trace elements are uniformly mixed, then inspected, weighed and packaged to obtain fertilizer additives.

Embodiment 2

Abstract

The invention provides a synergistic environment-friendly fertilizer aid. The synergistic environment-friendly fertilizer aid comprises the following components in percentage by weight: 20wt%-80wt% of biomass charcoal, 1wt%-10wt% of polymerization amino acid, 1wt%-15wt% of a soil structure conditioner, 0.2wt%-2wt% of a bioactivator, 0-10wt% of a slow release agent, 0-8wt% of compound trace elements, 0-10wt% of modified starch and 0-50wt% of modified attapulgite. The invention further provides a fertilizer containing the synergistic environment-friendly fertilizer aid. By virtue of the compounding of the components, the fertilizer aid has the efficacies of reducing heavy metal pollution, increasing the utilization rate of the fertilizer and improving soil.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a synergistic and environmentally friendly fertilizer additive and fertilizer. Background technique [0002] Plant growth requires a variety of nutrients. Among them, the macronutrient elements required for crop growth include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, and the micronutrient elements include boron, copper, iron, manganese, molybdenum, zinc, and chlorine. Fertilizer is the food of crops, and the nutrients needed for crop growth must be supplemented by applying fertilizers. With years of fertilization, soil compaction and acidification have accumulated, and a certain amount of heavy metal ions have accumulated, which has caused pollution in some areas and affected food safety. On the other hand, my country has a large amount of fertilization, and the utilization rate of fertilizer nutrients is low. Among them, th...
