Embodiment 1

[0023] A synergist YL-101, specifically iminodisuccinic acid and short peptide (polyaspartic acid) block copolymer, its molecular formula is as follows: [IDS] 16 -[PASP] 20

[0024] The elemental analysis results are shown in the table below:

[0025] Elemental analysis

[0026] through 1 H-NMR (D 2 O) Carry out NMR characterization as in the accompanying drawings figure 1 shown.

[0027] According to "GT / T21884-2008 Determination of Chelating Ability of Textile Printing and Dyeing Auxiliaries Chelating Agent", the chelating power of YL-101 and IDS was measured, and the test results are as follows:

[0028]

[0029]

[0030] It can be seen from the above table that the chelating ability of YL-101 to calcium, iron and copper is significantly greater than that of IDS.

[0031] According to "GB / T16632-2008 Calcium Carbonate Precipitation Method for Determination of Scale Inhibition Performance of Water Treatment", the scale inhibition and dispersion perform...

Embodiment 2

[0035] Contrast experiment of fertilizing wheat fields with synergistic urea

[0036] The synergists used are respectively YL-101, PASP, IDS, wherein, YL-101 is the sample of embodiment 1:

[0037] The experimental field is 2.2 mu each, and the measures such as sowing and base fertilizer are the same. The fertilization control experiment is carried out during the wheat greening period. Each synergist is added to urea at a rate of 3‰ / , and physically mixed with urea. The fertilization details are shown in the following table:

[0038]

[0039]

[0040] The results showed that compared with other ureas, the use of urea containing synergist YL-101 had darker green leaves, faster growth, fuller grains, and an increase of 20.77% per mu, which was better than IDS and PASP. The specific data analysis statistics are shown in the table below:

[0041] Test field

Embodiment 3

[0043] For synergist YL-101, specifically block copolymer of iminodisuccinic acid and short peptide (polyglutamic acid) [IDS] 10 -[PGA] 10 To characterize.

[0044] The elemental analysis results are shown in the table below:

Abstract

The invention discloses a synergist YL-101 and an application thereof, and concretely relates to an iminodisuccinate and short peptide block copolymer and an application thereof. The block copolymer adopts short peptide and / or derivatives thereof as a chain, and has slow release dispersibility; iminodisuccinate and / or derivatives thereof are embedded to increase the chelating property; and the short peptide and / or derivatives thereof and the iminodisuccinate and / or derivatives thereof are organically fused to form the fertilizer synergist which has fertilizer slow release and metal element chelating effects. The synergist has better dispersibility than the polypeptide, has better chelating performance than iminodisuccinic acid, is a novel polymeric chelating dispersant, can be used as the fertilizer synergist, and has substantial weight reducing, yield increasing and benefit increasing effects.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer synergists, and relates to a synergist YL-101 and its application, in particular to an iminodisuccinate-short peptide block copolymer and its application. Background technique [0002] With the rapid development of agriculture, it is the extensive use of chemical fertilizers, which has caused general salinization of the soil and serious environmental pollution. The quality of food and vegetables has declined, and the taste is not good. What is more serious is that a large amount of nitrate will accumulate in the soil, and excessive nitrogen and phosphorus will also pollute ground and surface water. Irrigation with nitrate-rich water will increase the nitrate content in crops, and nitrate may be reduced to carcinogen nitrite in the human body, directly leading to the outbreak of various cancers and diseases. [0003] The stable and increased production of agriculture is inseparable...
