20 14 obtained the national invention patent; 20 15 won the second prize of scientific and technological progress of Henan provincial government; 20 15 has been appraised by the expert appraisal Committee organized by Henan provincial science and technology department, and there is no similar report at home and abroad, reaching the international advanced level; 20 16 passed the evaluation of the evaluation committee of the Ministry of Agriculture and was designated as "soil conditioner [1]" for the promotion of high-tech products.
In 20 16 and 20 17, the National Agricultural Technology Center of the Ministry of Agriculture issued two documents, which were applied in grain, cotton, oil, sugar, fruit, vegetables and tea, and achieved remarkable results.
Experiments and demonstrations since 2007 have proved that Agri-star can loosen the root layer soil, break the root layer soil hardening, increase the soil aggregate structure, and create a good rhizosphere environment for root growth and development. Promote the deep development of root system, improve root volume and root cap activity; Complexing soil heavy metal ions can obviously reduce the concentration and activity of heavy metal ions in rhizosphere, reduce the content of heavy metals and pesticide residues in crops, and improve the stress resistance and continuous cropping resistance of crops. Applying Agri-star loosening agent to crops can improve product quality, increase crop yield and increase farmers' income. The general yield increase ratio is 10-30%, and the yield increase of individual crops reaches more than 50%.
Core technical principles of scientific and technological innovation achievements (loosening soil to promote roots);
Action mechanism of (1) surfactant
The low concentration of surfactant in this achievement enters the soil, which reduces the surface tension of soil clay and increases the pores in the soil. The soil bulk density is reduced and the soil is loose. Surface active substances belong to polymer materials, which bridge between soil particles to form large flocs and form aggregate structure. Surface active substances reduce surface tension, promote nutrient contact with plant roots, and are beneficial to absorption;
(2) Compound amino acids-biological stimulation
Compound amino acid part: the compound amino acid in the product contains natural biostimulants, which can promote the growth of plant roots; At the same time, due to the increase of plant roots, soil structure can be further improved and soil permeability can be increased.
(3) Trace elements-coordinating nutritional balance
Trace elements: Soil conditioner contains a variety of trace elements, which can adjust soil nutrient balance, promote crop growth and make up for the shortage of trace elements in soil.
