Embodiment 1

[0032] Preparation of Active Enzyme Model Compound 1

[0033] 1,2-Cyclohexylaminetetraacetic acid (CTA) and 2-mercaptoaniline are mixed at a mass ratio of 1:4, milled and mixed evenly, then put into a converter, and thermally condensed at 170°C for 8 hours until no water vapor is released until. After the condensation product was cooled to 50°C, it was put into an equal mass of absolute ethanol, stirred and left still, filtered, and the crude product was washed with distilled water, ethanol and ether, and dried at low temperature to obtain a white powder, which was ligand 4C, and the conversion rate was 67 %. The structure of ligand 4C is: .

[0034] Among them, R is

[0035] HRMS(ESI+)m / z calculated for C 38 h 35 N 6 S 4 (M+H):703.1806, found703.1811.

[0036] Ligand 4C and Fe(NO 3 ) 3 9H 2 O was mixed according to the mass ratio of 1:1.3, added to 2 times the mass of 95% ethanol, stirred and reacted at 60°C for 4 hours, cooled, filtered, and dried to obtain so...

Embodiment 2

[0038] Diethylenetriaminepentaacetic acid (DTPA) and o-phenylenediamine are mixed in a material ratio of 1:5, milled and mixed evenly, then put into a converter, and thermally condensed at 200°C for 24 hours until no water vapor is released. After the condensation product was cooled to 50°C, it was put into an equal mass of absolute ethanol to stir and stand still, filtered to obtain the crude product, washed with distilled water, ethanol and ether, and dried at low temperature to obtain a white powder, which was Ligand 6A, and the conversion rate was 72 %. The structure of Ligand 6A is:

[0039] Among them, R is

[0040] HRMS(ESI+)m / z calculated for C 44 h 44 N 13 (M+H):754.3843, found754.3845.

[0041] Ligand 6A and MnCl 2 4H 2 O was mixed according to the ratio of the amount of substances at 1:1, added to ethylene glycol with 2 times the mass, stirred and reacted at 60°C for 4 hours, cooled, filtered, and dried to obtain solid powder and transparent clear night. ...

Embodiment 3

[0043]Ethylenediaminetetraacetic acid (EDTA) and o-phenylenediamine are mixed at a material ratio of 1:4, milled and mixed evenly, then put into a converter, and co-heated and condensed at 180°C for 16 hours until no water vapor is released. After the condensation product was cooled to 50°C, it was put into an equal mass of absolute ethanol to stir and stand still, filtered to obtain the crude product, washed with distilled water, ethanol and ether, and dried at low temperature to obtain a white powder, which was Ligand 1A, and the conversion rate was 69 %. The structural formula of Ligand 1A is:

[0044] Among them, R is

[0045] HRMS(ESI+)m / z calculated for C 34 h 33 N 10 (M+H):581.2890, found581.2891.

[0046] Ligand 1A and CuSO 4 4H 2 O was mixed according to the mass ratio of 1:1.1, added to 2 times the mass of DMF, stirred and reacted at 60°C for 4 hours, cooled, filtered, and dried to obtain solid powder and transparent clear night. Solid powder was the fina...

Abstract

The invention provides an active enzyme model compound, and a foliage fertilizer and a synergist based on the same, and a using method of the synergist, and belongs to the field of biochemistry. According to the active enzyme model compound, an active center is formed through coupling of organic ligands and metal ions, then a stress resistance mechanism of crops themselves is started through a variety of reaction mechanisms, and the active enzyme model compound can be used in different grow periods of the crops to achieve pest resistance, sterilization, waterlogging resistance, drought resistance and cold resistance of the crops and increasing of both production and income. When the active enzyme model compound is used for resisting the insect pest disaster, the use concentration of the active enzyme model compound reaches 500-1000 ppm, and no obvious side effects are showed on plants.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to an active enzyme model compound and a foliar fertilizer based on the compound, a synergist and a method for using the synergist. Background technique [0002] With the continuous development of cities, the contradiction between population and cultivated land is becoming more and more prominent. How to increase the yield per unit area to feed the growing population's demand for food will become an important issue. The application of chemical fertilizers is one of the effective means to increase grain production, but excessive use of basic chemical fertilizers (urea, ammonium nitrate, monoammonium phosphate, diammonium phosphate, potassium sulfate, potassium chloride, etc.) will cause soil compaction and pollute the environment. Synergist products through biological induction can activate the crop's own stress resistance mechanism, which can not only increase produc...
