Description
Technical field
The invention belongs to agricultural product security fields, are related to a kind of preparation and method for inhibiting cadmium enrichment in rice.
Background technique
In recent years studies have shown that cadmium (Cadmium, Cd) is that known toxicity is most strong and the contaminated most serious in farmland
One of heavy metal；Rice is the staple food source of 50% or more population of China, but rice is to absorb the strongest large cereal of cadmium ability to make
Object, cadmium is enriched in rice causes in rice cadmium exceeded serious, causes the great attention of the Chinese government and researchers.
Cadmium preparation drops in convenient and effect stability rice in Study On Rice production, and nutritive value and grain security to rice all have weight
Want meaning.
Chinese patent 201410056774.6 discloses a kind of preparation that accumulates in crops of reduction cadmium and its use, and one
Kind reduces the preparation that cadmium accumulates in crops, and said preparation includes the component of following concentration: reductive glutathione 50 ~ 80
Mg/ L, sodium selenite 15 ~ 30mg/ L, zinc sulfate 2.0 ~ 3.0 × 103Mg/ L, but such preparation is suitable only for mild or moderate cadmium
Contaminated areas, and to cadmium reduced rate in rice grain less than 35%, except cadmium effect is barely satisfactory.
Thus, how to remove or reduce the cadmium in the crops of heavy Cd contamination area is current technology in the urgent need to address
Problem.
Summary of the invention
The present invention is a kind of suitable for the preparation and method for inhibiting cadmium enrichment rice in heavy Cd contamination area, to solve
The prior art technical problem undesirable except cadmium effect.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of preparation for inhibiting cadmium enrichment in rice is designed, the main raw material for preparing of preparation described in every 1L includes the Asia 60 ~ 90mg selenium
Sour sodium and 10 ~ 30mL An Rongle.
Preferably, the main material of preparation described in every 1L includes 70mg sodium selenite and 20mL An Rongle.
When preparation, the sodium selenite of corresponding number and peace is taken to melt happy mixing moisturizing to 1L, mixing.
A kind of method inhibiting cadmium enrichment in rice is provided, is sprayed on rice plant of tillering stage, heading stage and/or Early filling stage blade face
Apply the preparation that cadmium is enriched in above-mentioned inhibition rice, 0.08 ~ 0.12L/m of the amount of spraying2。
It rains if spraying in rear 30min, sprays again.
0.2 ~ 0.3 kg/m of lime is first spread fertilizer over the fields into rice field before rice transplanting2。
Compared with prior art, the beneficial technical effect of the present invention lies in:
1. invention formulation preparation and application is easy, the equipment and cumbersome technique of no complexity pass through artificial or equipment leaf
Face sprays compound formulation solution of the invention, and process for preparation is simple, operation is convenient and quick, easy to spread.
2. after application, the drop cadmium significant effect in rice；
3. non-environmental-pollution: sodium selenite and An Rongle can be absorbed rapidly by plant, noresidue, to wheat seed and soil without
Pollution.
4. the present invention is suitable for the heavily contaminated area of cadmium, preparation stabilization, reasonable recipe is convenient for saving.
5. compatibility of the present invention is reasonable, specific as follows:
Selenium (Selenium, Se) can water lift rice growth rate, inhibit Lipid peroxidation metabolism and increase oxidation resistance, apply certain
The selenium of concentration can enrichment of the antagonism cadmium in rice strain；An Rongle (containing lecithin, vitamin E etc.) is contacted and is wrapped up sodium selenite
Molecule can reduce the surface tension of solution；It carries out being conducive to the wax coat and leaf across rice leaf surface when foliage-spray
Piece stomata, and by the transdermal delivery of cell wall, transport of the rice in-vivo element between different tissues is realized, to improve sub- selenium
The effect that sour sodium resistance control cadmium is accumulated in seed.
