一、Profile of bioactive peptides
Bioactive peptides from a
complex linear dipeptide to
different peptides of the
generic ring structure, multifunctional 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
（一） bioactive peptides can be directly absorbed by plants, and promote the
growth and development of plants
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.

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.
（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.
（四）Application of bioactive peptides can promote the
decomposition of straw and other organic materials.
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.
（五）Application of bioactive peptides can improve the quality of
agricultural products
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.
Promote coloring,
fruit symmetry, early
maturity 15 days.
