Embodiment Construction

[0010] The present invention is further described below in conjunction with specific embodiments.

[0011] A polymeric amino acid ecological slow-release fertilizer: it is characterized in that it comprises 99-99.3% NPK compound fertilizer, 0.7-1% additive, and said additive comprises 20% polyaspartic acid, 20% polyglutamic acid , 60% nitrification inhibitor, and the nutrient release period of the polyamino acid ecological slow-release fertilizer reaches more than 100 days.

[0012] The nitrification inhibitor is dicyandiamide, methylpyrazole and cloxazone, and the mass ratio is 3:1:2.

[0013] If the NPK compound fertilizer contains 45% of the total NPK nutrients and 25% of the nitrogen nutrient, the amount of additive added is 0.8%; the total NPK nutrient is greater than 48%, and the nitrogen nutrient is more than 26% The addition amount of the additive in the compound fertilizer is 1%; the addition amount of the additive in the compound fertilizer with the total nitrogen, ...

Abstract

The invention provides an ecologic slow release fertilizer of polymerization amino acid, which is characterized by comprising 99 to 99.3 percent of nitrogen-phosphorus-potassium composite fertilizer, and 0.7 to 1 percent of additive, the additive comprise 20 to 30 percent of polyaspartic acid, 20 to 30 percent of polyglutamic acid, 40 to 60 percent of nitrification inhibitor, and the nutrient release period of the ecologic slow release fertilizer of polymerization amino acid can reach more than 100 days.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a polymerized amino acid ecological slow-release fertilizer. Background technique [0002] For a long time, my country's chemical fertilizer application has the characteristics of large amount of fertilizer application, excessive nutrient loss, and low crop absorption, which will cause waste of resources and environmental pollution. Therefore, in the study of enhancing fertilizer absorption and improving fertilizer utilization, Reducing the input of fertilizers and reducing costs is of great significance to the agricultural development of our country. Contents of the invention [0003] In view of the above problems, the present invention provides a polyamino acid ecological slow-release fertilizer, which can not only prevent the loss of nutrients, but also improve the utilization rate of nutrients. [0004] A polymeric amino acid ecological slow-release fertilizer: it is characterized in that it...
