Embodiment 1

[0031] The fertilizer synergistic additives are 34.7g of polyglutamic acid, 69.4g of sodium citrate, 208.3g of diatomaceous earth and 381.9g of zeolite powder. The above-mentioned materials are crushed and ground and mixed evenly.

[0032] The fertilizer synergistic additive obtained above is mixed with the compound fertilizer at 4‰:1 to obtain the polyamic acid fertilizer. Among them, the compound fertilizer components are 33.5kg of urea, 106.7kg of superphosphate and 33.4kg of potassium sulfate.

[0033] The polyamic acid fertilizer and the compound fertilizer obtained above are respectively used in the cultivation process of rapeseed, and the growth period is 50 days. The compound fertilizer was used as the control group.

[0034] Tests have shown that compared with the control fertilizer treatment without synergistic additives, under the same fertilizer application (urea 33.5kg, superphosphate 106.7kg and potassium sulfate 33.4kg), the utilization rate of N increased by 2...

Embodiment 2

[0036] The fertilizer synergistic additives are 37.4g of polyglutamic acid, 22.4g of sodium citrate, 37.4g of diatomaceous earth and 280.5g of zeolite powder. The above materials are pulverized and finely ground and then mixed evenly.

[0037] The fertilizer synergistic additive obtained above is mixed with the compound fertilizer at a weight ratio of 11‰:1 to obtain a polyamic acid fertilizer. The compound fertilizer components are 17kg of urea, 12kg of heavy superphosphate and 5kg of potassium chloride.

[0038] The polyamic acid fertilizer and compound fertilizer obtained above were used in the cultivation process of corn respectively. The growth period was 135 days, and the base fertilizer was applied in one time. No top dressing was applied in the middle period, and the compound fertilizer was used as the control group.

[0039] Experiments have shown that compared with the control fertilizer treatment without synergistic additives, under the same fertilizer conditions (1...

Embodiment 3

[0041] The fertilizer synergistic additives are 37.1g of polyglutamic acid, 18.6g of sodium citrate, 37.1g of diatomaceous earth, and 278.3g of zeolite powder. The above materials are pulverized and finely mixed before mixing.

[0042] The fertilizer synergistic additive obtained above is mixed with the compound fertilizer at a weight ratio of 14‰:1 to obtain a polyamic acid fertilizer. Among them, 23kg of compound fertilizer, in which N:P:K=17:17:17, and 30kg of urea was added to the compound fertilizer.

[0043] The polyamic acid fertilizer and compound fertilizer obtained above were used in eggplant cultivation in the form of one-time application of base fertilizer, no topdressing in the mid-term, and the compound fertilizer was used as a control group.

[0044] Experiments have proved that compared with the control fertilizer treatment without fertilizer synergist, under the same fertilizer application (compound fertilizer 23kg, where N:P:K=17:17:17), the use of polyacids...

Abstract

The invention provides a synergistic additive for a fertilizer and application of the synergistic additive, and relates to the synergistic technology for fertilizers, in particular to a synergistic additive for a fertilizer and application of the synergistic additive. The synergistic additive for the fertilizer comprises, by weight, from 1 to 20% of polyglutamic acid, from 1 to 10% of sodium citrate, from 10 to 30% of diatomaceous earth and from 40 to 60% of zeolite powder. The synergistic additive is a polymerized and purified substance of amino acid, can be biologically degraded into amino acid monomers to be absorbed by plants, and is free of residues and pollution, and the fertilizer produced by the synergistic additive is applicable to various crops and soils in various regions.

Description

technical field [0001] The invention relates to a fertilizer synergistic technology, in particular to a fertilizer synergistic additive and its application. Background technique [0002] For a long time, my country's chemical fertilizer application has the characteristics of large amount of fertilization, excessive nutrient loss, low crop absorption and utilization rate, and environmental pollution and resource waste caused by excessive fertilization. Therefore, research on fertilizer efficiency technology to improve fertilizer utilization It is of great significance to my country's agricultural development and ecological environment protection. [0003] At present, there are three main researches on fertilizer efficiency technology in my country: 1. Using inhibitor technology to control the activity of soil enzymes, thereby controlling the transformation and form of fertilizers, reducing loss and improving utilization; 2. Using inorganic coating technology, Control the conta...
