Description
Technical field
The invention belongs to the technical fields of chemical residual degradation, and in particular to one kind being based on amino acid fertilizer rice pesticide
The method of residue degrading.
Background technology
Rice is the staple food of people, and the quality safety of rice is directly related to the health of people, and then influences people
Life, production and social stability, economic development, social progress.The production process period of rice is long, is influenced by naturally, disease pest
Evil frequent occurrence, in order to mitigate loss of the pest and disease damage harm to rice yield, prevention pest and disease damage is carried out frequently with pesticide.
For current pesticide, while killing pest and disease damage, a part can be remained in rice plant, paddy.Rice
Paddy becomes the rice and rice made products of our daily consumptions by processing.As staple food, the safety of rice is concerned.Cause
For the pesticide residue in rice, people's health is directly affected.For the residual detection of the agriculture of rice, the rice agriculture that China carries out is residual
Detection has 183 kinds.More than 300 kinds of Japan's detection, and European Union has reached more than 500 kinds.It is provided in China's present standard, phosphide
≤ 0.05mg/kg, the mg/kg of bromomethane≤5, the mg/kg of malathion≤0.1, the mg/kg of pirimiphos-methyl≤5, decis
≤ 0.5 mg/kg, the mg/kg of six six six≤0.05, the mg/kg of DDT≤0.05, the mg/kg of other pesticides≤0.02.Another party
Face can utilize although plant is not eaten in people as animal sources feed in animal body, form harmful poultry
Product.It by straw-returning, and can be deposited in soil, polluted underground water, form pollution of area source.
With the improvement of social and economic condition, people increasingly increase the demand of high-end superior rice.For high-grade high-quality
For rice industrialization development, the residual problem of agriculture seriously constrains the development of the industry.Studies have shown that passing through physics, chemistry, biology etc.
Means can promote degradation of pesticide.In the research decomposed for farm chemical ingredients, using multiple-microorganism production organic fertilizer,
Decomposition and inversion is carried out using a variety of biological enzyme formulations, pesticidal effects are improved using bleeding agent sticker to reduce applications of pesticide amount
As three kinds of most representational methods.Wherein microorganism or Enzymology method have the characteristics that nontoxic, non-secondary pollution, are close
The important directions of research in several years.Efficient degrading bacteria is screened, its thick degradation enzyme solution is extracted, optimizes crude enzyme liquid pharmaceutical formulation, exploitation is used
In the enzyme preparation of agricultural product especially garden stuff pesticide residue degradation, good result is obtained.
In recent years, enzymatic reaction principle hydrolyse phosphate esters key, the research of degrading pesticide residues are passed through using pesticide degradable enzyme
As hot spot, it is the current most effective technological means for solving Pesticide Residue, there are the spies such as safe efficient, non-secondary pollution
Point.As the important means of Development of Organic Agriculture.In terms of Rice Production, using pesticide synergistic agent to reduce applications of pesticide amount use
It is relatively more in the report of safe ecological rice production, but carry out biodegradation technique using biological enzyme formulation and carry out rice safety
Production is rarely reported rice pesticide residual degradation effect, method of administration etc..
Invention content
The purpose of the present invention is to provide a kind of method based on amino acid fertilizer rice chemical residual degradation, the present invention
It is applied on rice using the amino acid fertilizer rich in biological enzyme formulation, by paddy growth, absorption, is turned in liquid form
Change, it is residual to reduce rice middle peasant to be converted to farm chemical ingredients in rice.The amino acid fertilizer of the present invention is with blade face
It sprays, sorption enhanced, and then degrading pesticide ingredient, the residual safety of the agriculture to improve high-grade superior rice；The present invention uses amino
Sour organic fertilizer is respectively adopted amino acid fertilizer to rice seed soaking, in rice striking root phase, heading stage and pustulation period and carries out spraying leaf
Face, and rice fertilizer efficiency absorption maximum is realized using repeatedly progressive application amino acid fertilizer in the rice striking root phase；And in rice
Critical period large dosage of earing applies amino acid fertilizer, and the effect of rice chemical residual degradation has been effectively ensured, and has preferable
Practicability.
The present invention is achieved through the following technical solutions：It is a kind of based on amino acid fertilizer rice chemical residual degradation
Method mainly includes the following steps that：
Step S101：It is soaked seed to rice with amino acid fertilizer；
Step S102：Amino acid fertilizer is applied to rice seedling using the method for foliage-spray before rice striking root, divides 3 times and applies
Add, applies amino acid fertilizer for the first time when the rice striking root phase starts, and last time applies amino acid fertilizer in rice seedling
Apply before 6 leaf of seedling；
Step S103：Amino acid fertilizer is added to Fertilizer in Rice using the method for foliage-spray in rice ear sprouting period, point 2 applications,
Among it every 3-7 days；
Step S104：Amino acid fertilizer is added to Fertilizer in Rice using the method for foliage-spray in rice milking stage area, point 2 applications,
Among it every 3-10 days, realization degrades to the residual of pesticide in rice.
Under the premise of normal use pesticide, by the amino acid of advanced biological enzyme technology and the production of organic fertilizer technique set
Organic fertilizer is applied on rice in liquid form, by growth, absorption, conversion, is converted to farm chemical ingredients, to reach drop
The residual purpose of low agriculture.The amino acid fertilizer of the present invention is with foliage-spray, sorption enhanced, and then degrading pesticide ingredient, to carry
The residual safety of agriculture of top grade superior rice.This and increase compound, utilize all different, the utilizations such as plate-out ability, increase pesticide pharmacological property
Unique bio-enzyme degradation effect, degrades to the toxic ingredient of common pesticides, so more thoroughly, there are no evils.
The amino acid fertilizer is the Zhan Shi biologies conversion that Weihai City's Zhan Shi biologies convert the production of enzyme preparation Co., Ltd
Enzyme, registration are entitled：A kind of amino acid fertilizer.The method of the foliage-spray be the prior art and be not the present invention improvement
Point, so it will not be repeated.Other reagents of the rice seed soaking be the prior art and be not the present invention improvement, therefore it is no longer superfluous
It states.
A variety of mineral nutritions and active material are combined containing beneficial microbe in amino acid fertilizer, many beneficial water can be generated
The substance of rice growth promotes rice root flourishing, and lateral root is mitogenetic rapidly, increases capillary radical amount, and root mass becomes larger, and improves and inhales fertilizer suction
Outlet capacity, makes that stalk is sturdy, toughness enhancing, and blade is straight and upright, and canopy microenvironment is good, and photosynthesis enhancing improves Rice Resistance
Drought, heat resistanceheat resistant, freeze proof and lodging tolerance.Wherein studies have shown that bio-feritlizer can effective degrading pesticide residues, so that herbicide is pressed down
Phase processed shortens to 2 ~ 3 d from 7 ~ 15 d, and yield, Practice for Pesticide Residue in Agricultural Products also can be improved in the case where not influencing herbicidal effect
Far below EU criteria.
