Problems solved by technology

[0004] In the 1990s (Feng Yuanqi, "On New Nitrogen Fertilizer - Long-acting Ammonium Bicarbonate", "Fertilizer Design", 2007, 45 (3): 59-62; Wang Zuyi, Chen Weiwei, Lao Linyao, "Synthetic ammonium bicarbonate Application in Agriculture", "Phosphate Fertilizer and Compound Fertilizer", 1995, (3): 77-80), a long-acting ammonium bicarbonate was developed by adding ammonium ion stabilizers such as dicyandiamide to ammonium bicarbonate The product has achieved certain effects in application, but this kind of stable fertilizer cannot be used on legume crops, and because of the high price of ammonium ion stabilizers, there is no further promotion in the production and application of ammonium bicarbonate

Abstract

The invention relates to a glutamic acid synergistic ammonium bicarbonate fertilizer and a production method thereof. The ammonium bicarbonate fertilizer comprises components in percentage by weight as follows: 0.30%-1.20% of a glutamic acid synergist and 98.80%-99.70% of ammonium bicarbonate. Compared with common ammonium bicarbonate, the glutamic acid synergistic ammonium bicarbonate has the characteristics of good yield-increasing effect, high nutrient utilization rate and environment-friendliness as well as simple production technology, low cost, wide raw material resource, easiness in operation, benefit to industrial application and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of agricultural chemicals. More specifically, the present invention relates to a glutamic acid synergistic ammonium bicarbonate fertilizer, and also relates to a production method of the glutamic acid synergistic ammonium bicarbonate fertilizer. 【Background technique】 [0002] For a long time, low fertilizer use efficiency and its environmental risks have been the focus of people's attention, and the negative impact of chemical fertilizer application on the environment is becoming more and more serious. Countries all over the world have gradually realized that the development of new slow-release fertilizers with high utilization rate is one of the most effective ways to improve nutrient use efficiency. Since the 1960s, the research and development of various new fertilizers aimed at improving the utilization rate of fertilizers has become a research hotspot in the field of fertilizers in the world. Throu...
