Abstract
The invention discloses a kind of preparation method for reducing the novel mercapto foliar fertilizer of cadmium content in rice, the foliar fertilizer is using dimercaptosuccinic acid and allyl cysteine as primary raw material, it is aided with starch again and particle is made in dextrin, vacuum packaging, it is reduced the new foliar fertilizer of cadmium content in rice, the foliar fertilizer was uniformly sprayed in rice leaf surface in Rice Heading florescence；It is unstable to be oxidized easily because dimercaptosuccinic acid and allyl cysteine contain sulfydryl, therefore vacuum drying and vacuum packaging are used in the present invention in formulation process.
Description
Technical field
The present invention relates to rice technical field of fertilizers, more particularly to a kind of novel mercapto blade face for reducing cadmium content in rice
The preparation method of fertilizer.
Background technology
Cadmium is one of most strong heavy metal element of bio-toxicity.Be mainly collected in kidney, liver, bone, cardiovascular system,
Immune system etc..Chemism of the cadmium in soil is strong, toxicity is lasting, endangers the mankind easily by the enrichment of food chain and is good for
Health.Soil heavy metal cadmium situation very severe, in April, 2014, the national Soil Pollution Investigation publication of announcement was shown,
The point position exceeding standard rate highest of cadmium, the cadmium pollution of wherein rice terrace are the severeest.
Rice is the maximum cereal crops of Chinese cultivated area, and the grain source that China is important.Rice is easily enriched with
Heavy metal cadmium, harm to the human body degree is larger after cadmium pollution rice is eaten for a long time, and itai-itai is the disease that typical cadmium triggers.Cadmium
It is difficult to excrete after into human body, the half-life period in human body reaches 10-25.The Hunan poison rice event of 2013, causes
The extensive concerns of various circles of society.
To reduce cadmium content in rice, scientist develops a variety of methods at present.Quick lime is such as added in soil, is reduced
P in soil H values can play is passivated Cadmium in Soil to a certain extent, and reaching reduces the purpose that cadmium is transported into rice.Also someone develops
Go out and the method that porous adsorbent carries out adsorbing fixing to cadmium is added into soil.It is higher cost to be present in these methods, and
Long-term a large amount of uses may change soil physical chemistry property, potential ecological risk be present.In addition, somebody have developed
Leaf surface conditioning agent, a certain degree of production-increasing function can be not only played after spraying on rice leaf, but also cadmium can be reduced
Transhipment into rice.But the factor such as this kind of conditioner climate, soil nutrient has a great influence, there is that effect is unstable to ask
Topic.The invention belongs to a kind of foliar fertilizer for blocking cadmium ion to be transported into rice.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of novel mercapto for reducing cadmium content in rice
The preparation method of foliar fertilizer.
Technical scheme is as follows：
The preparation method of the novel mercapto foliar fertilizer of cadmium content, comprises the following steps in a kind of reduction rice：
A, 180-360mM dimercaptosuccinic acids are weighed with balance, 400-600mM allyl cysteine, be dissolved in dense
Spend in the sodium hydroxide solution for 1.0M/L, add water and be diluted to 1 liter；
B, 150-250g starch is added in the aqueous solution into step A, 250-350g dextrin, is well mixed, softwood is made,
Agglomerating, light pressure is held to dissipate；
C, the softwood obtained in step B was extruded into 20 mesh copper sieve, wet granular is made, is placed in vacuum drying chamber in 45-
10-15 hours are dried under reduced pressure at 55 DEG C；
D, the dry particle obtained in step C is separated into fine powder with 80 mesh sieves and 100 mesh sieves, collection can by 80 mesh sieves and
The particle of 100 mesh sieves can not be passed through；
E, the particle obtained in step D is vacuum-packed in polybag on vacuum packing machine according to 100g/ bags, i.e.,
Can.
Preferably, in described step A, after the amount of the sodium hydroxide solution of addition is diluted with water, regulation pH value is 8.0-
8.5 it is defined.
Preferably, the application method of described novel mercapto foliar fertilizer is：In Rice Heading florescence, according to 100g/ mus
Dosage, take foliar fertilizer to be dissolved in 30L water, uniformly spray in rice leaf surface.
The present invention is advantageous in that：Using dimercaptosuccinic acid and allyl cysteine to be main former in the present invention
Material, then be aided with starch and particle is made in dextrin, vacuum packaging, it is reduced the new foliar fertilizer of cadmium content in rice, the blade face
Fertilizer was uniformly sprayed in rice leaf surface in Rice Heading florescence；Due to dimercaptosuccinic acid and the Guang ammonia of pi-allyl half
Acid contains sulfydryl, unstable to be oxidized easily, therefore uses vacuum drying and vacuum packet in the present invention in formulation process
Dress.
