1. Application of bioactive peptides in agriculture Jinan,China Haiduan Gao executive manager 2014.05.10

2. Bioactive peptides from a complex linear dipeptide to different peptides of the generic ring structure, multi- functional compound is a protein derived from the 25 natural amino acid protein with a different configuration and arrangement of the component. 一、 Profile of bioactive peptides dipeptide polypeptide protein AA

3. The ring structure of Tyrothricin The linear structure of glutathione

4. Currently, bioactive peptides are widely used in medicine and food etc.,but the application in agricultural production has just begun ……

5. With the expansion of the scale of production of bioactive peptides and lower production costs,it is possible for peptides widely applications in agricultural production.

6. Modern plant nutrition studies found that: protein substances, decomposition in the soil, mostly in the form of short chain peptides are absorbed by plants, the proportion of free amino acids in the form of absorption is very small. Further research has revealed the peptide is absorbed faster and more than free amino acids, indicating that the biological potency of the peptide and nutritional value higher than the free amino acids. This is exactly where the charm of active peptides.

7. 二、 The actions of bioactive peptides in agricultural production

8. 1. Promote plant root development, so that plant roots lush, improve the absorption of nutrients and water use efficiency. （一） bioactive peptides can be directly absorbed by plants, and promote the growth and development of plants

9. 2. Promote root cell growth, cell arrangement rules dense, well-developed roots, soil resilience invading pathogens enhanced, thereby reducing the incidence of soil-borne diseases.

10. （一） bioactive peptides can be directly absorbed by plants, and promote the growth and development of plants 3. When foliar application, peptides can be directly absorbed by cells of the foliage, the leaves stretch, thick, shiny hair green, photosynthetic enhancement, more efficient use of light can transform carbon dioxide into glucose and other organic matter, crop production increase.

11. （一） bioactive peptides can be directly absorbed by plants, and promote the growth and development of plants 4.After the short chain peptides are absorbed in plants can be directly involved in protein synthesis, the use of inorganic nitrogen faster than the rate of protein synthesis, high efficiency, consume less ATP, thereby reducing pressure on plant production systems to make more ATP for material synthesis and fruit seeds, which increase production.

12. （一） bioactive peptides can be directly absorbed by plants, and promote the growth and development of plants 5.Amino acids and short chain peptides can be directly used for the synthesis of various enzymes in plants, enhancing anabolic ability of plants to accelerate the growth and development of plants, the plant yield, early maturity.

13. （二） bioactive peptides can be absorbed by soil microorganisms, promoting soil bacteria Population growth, making it the dominant flora. 1.Administration of bioactive peptides can make beneficial soil microbes surge in the number and improve the ecological environment of the soil, improve soil enzyme activity and soil fertility, enhancing the degree of soil aggregates, improving the ability to retain water and nutrients.

14. （二） bioactive peptides can be absorbed by soil microorganisms, promoting soil bacteria population growth, making it the dominant flora. 2.Administration of bioactive peptides beneficial microorganisms in the soil can become dominant bacteria in the soil, the nutrients, oxygen and other aspects of space colonization compete with pathogenic microorganisms, thereby inhibiting the growth of pathogens in soil, prevent soil diseases, and can ease cropping effect to some extent.

15. （三） bioactive peptides can improve bio-fertilizers, bio-pesticides, organic material decomposition agent effects of biological agents and other applications. 1.Bioactive peptides can promote bacterial solution of potassium phosphate dissolution of potassium, phosphorus and bacteria and other microorganisms function, can improve the ability of microbial organisms secrete plant growth regulators, can provide microbial synthesis of polysaccharides, peptides, vitamins and other plant capacity factor promoting students.

16. （三） bioactive peptides can improve bio-fertilizers, bio-pesticides, organic material decomposition agent effects of biological agents and other applications. 2.Bioactive peptides can improve actinomycetes, Trichoderma, Bacillus polymyxa biocontrol ability to secrete antimicrobial substances.

17. One reason for the slower decomposition of straw and other organic material in the soil is its low protein content, which resulted in its soil microenvironment C / N ratio is high, with a maturity of some microorganisms can not multiply effect, leading to maturity very slow, very long maturity period. Administration of bioactive peptides straw and other organic materials can reduce soil microenvironment in which the C / N, promote composting microbial growth, accelerate the decomposition process and shorten the maturity period. （四） Application of bioactive peptides can promote the decomposition of straw and other organic materials.

18. Bioactive peptides can be administered as soon as possible to restore the ecological balance, can make it more sweet fruits, vegetables tastier and better food quality. Good storage, place a long time to really restore the green organic agricultural products. （五） Application of bioactive peptides can improve the quality of agricultural products

19. Promote coloring, fruit symmetry, early maturity 15 days.
