Problems solved by technology

[0003] The main reasons for low fertilizer use efficiency include excessive fertilization in high-yield farmland, neglect of soil and environmental nutrient utilization, underutilization of crop yield potential, and failure to effectively prevent and control nutrient loss, etc.
Therefore, it is imminent to improve crop yield and fertilizer nutrient utilization efficiency, and to coordinate high crop yield and environmental protection. At present, there are also many researches on fertilizer synergists to improve fertilizer utilization efficiency abroad and at home, mainly from the nitrification inhibition of chemical synthesis. However, there are these defects: 1. It is greatly affected by external environmental factors and the effect is unstable; 2. Its own Affected by volatility, mobility in soil, decomposition speed and other conditions, the effect is limited; 3. High price and increased use cost; 4. High toxicity and great impact on crops or soil and the environment
5. Abuse and unreasonable use of regulators lead to poor plant quality or negative effects

[0041] There were 3 pesticide treatments, 1 control without fertilization and 1 control with conventional fertilization in the experiment. There were five treatments in total. 20 cabbage plants were used in each group, and the experimental data were averaged. Fertilizer is the powdered fertilizer of 18-6-6 (Chengdu Wangpai Chemical Fertilizer Co., Ltd., production date 20120809). The various planting tanks are isolated, the fertility status is consistent, and the management of other diseases, insect pests and weeds is consistent. The specific method and dosage are shown in Table 2.

Abstract

The invention relates to a fertilizer synergist and application thereof, belongs to the field of a fertilizer, and aims at solving the technical problem, namely providing an efficient, safe and inexpensive fertilizer synergist. The fertilizer synergist disclosed by the invention comprises the following active components: 1-10 parts of polymerization amino acid and 0.5-2 parts of nitrification inhibitor, wherein the nitrification inhibitor is a compound with inhibiting effects on nitrobacteria and denitrifying enzyme in soil. Furthermore, the invention also discloses a preparation method and application of the fertilizer synergist. The polymerization amino acid in the active components of the fertilizer synergist disclosed by the invention is a polymer biopolymer of amino acid. Thus, the fertilizer synergist is easily biodegraded, and safe to the soil and environment, and has the advantages of being efficient, safe and inexpensive.

Description

technical field [0001] The invention relates to a fertilizer synergist and its application, belonging to the field of fertilizers. Background technique [0002] In recent years, relevant experts from the Ministry of Agriculture have carried out more than 1,000 field experiments in the main grain producing areas of the country, and analyzed the partial productivity, agronomic efficiency, fertilizer use efficiency and physiological conditions of China's main grain crops rice, wheat and corn under the current conditions. It was found that the agronomic efficiencies of nitrogen fertilizers for rice, wheat and corn were 10.14kg / kg, 8.0kg / kg and 9.8kg / kg, respectively, and the nitrogen use efficiencies were 28.3%, 28.2% and 26.1%, which were far below the international level. , showing a downward trend compared with the 1980s. [0003] The main reasons for low fertilizer use efficiency include excessive fertilization in high-yield farmland, neglect of soil and environmental nutri...
