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.

Currently, bioactive peptides are widely used in medicine and food

etc.,but the application in agricultural production has just begun ……

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.

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.

二、 The actions of bioactive peptides in agricultural production

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

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.

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.

（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.

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.

（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.

（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.

（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.

（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.

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.

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

Promote coloring, fruit symmetry, early maturity 15 days.
