Abstract
The invention discloses a kind of rare earth chitin.It is formed at certain condition ligand complex by chitin and rare earth element or its oxide compound, muriate.The present invention has fully utilized chitin and the rare earth advantage to the promoter action of farm crop, growth of animal, as fertilizer and fodder additives, can increase substantially crop yield and animal production rate.The present invention can be widely used as the additive of farm crop fertilizer and animal-feed.
Description
The present invention relates to a kind of animal-feed and vegetable fertilizer additive, a kind of especially rare earth chitin that promotes animal and plant growth.
Because rare earth can promote photosynthesis of plants, therefore a lot of countries study the application of rare earth on agricultural in succession, China has just developed rare earth nitrate as plant growth agent during " six or five ", " the Seventh Five-Year Plan " produced amino-acid rare earth again and be used for promoting crop growth.More than two kinds of rare earth effect of increasing production generally between 6-15%; Chitin is a kind of glycosaminoglycan that extract from shrimp, crab shell, external have certain effect as fodder additives, plant growth agent, soil improvement agent, is used for fodder additives but rare earth is combined the formation rare earth chitin with chitin, plant production agent etc. do not appear in the newspapers both at home and abroad as yet.
The objective of the invention is to fully utilize the advantage that rare earth and chitin produce animals and plants and a kind of rare earth chitin that promotes that the animals and plants production effect is good is provided.
The technical solution that the object of the invention realizes is: a kind of rare earth chitin that is used to promote animal and plant growth is characterized in that its chemical structural formula is:
Wherein RE is a lanthanide series rare-earth elements, the oxide compound of lanthanide series rare-earth elements, muriate.
RE in the technical solution that the object of the invention realizes can be the L in the lanthanon
a, C
e, P
r, N
dOne of four kinds of elements.
RE in the technical solution that the object of the invention realizes can be L

Principle of the present invention is: chitin is under the effect of organic solvent or hydrochloric acid, chitinase, cellulase, chitoanase, can become rare earth chitin with the rare earth coordination complexing or become other types metal chitin with other element ligand complexes, this makes rare earth element organise, make the chitin saltization simultaneously, behind rare earth and the chitin ligand complex, comprehensive effectiveness is separately improved.
Rare earth chitin of the present invention compared with prior art, its remarkable advantage is: be used for fish, shrimp, crayfish cultures such as prawn, eel 1., can strengthen digestive enzyme activity, raising protein is to amino acid whose transformation efficiency and promote three antelopes of feed to circulate, be beneficial to their metabolism to shell in the abundant absorption of feed nutrient and shrimp, the crab growth, can disease prevention, improve a poor appetite, make it individual and increase, stout and strong.Experimental result shows, makes fodder additives with rare earth chitin of the present invention, can make the prawn culturing volume increase more than 10%; Trowel fish rate of increase improves about 30%; 2. be used for crop growth, can promote the root growth of crop, strengthen the root system vigor, improve fertilizer utilization ratio, make the crop early growth and quick tiller, the stem branch is sturdy, increase chlorophyll content simultaneously, improve the biochemical enzyme activity, prolong blade function, prevent virus, improve anti-morning, anti-element and capacity for the resistance to lodging, improve setting percentage and fruiting rate, increase output, improve quality.Experiment showed, that rare earth chitin of the present invention is used for plant-growth, can make cotton volume increase 8.1-14.6%, wheat increase yield 11.6-17.2%, paddy rice 9.0%, vegetables 11.1-24.3%; 3. rare earth chitin manufacturing of the present invention is simple, and one-tenth one is lower, is easy to widespread use.
Below by embodiment the present invention is further described.
Embodiment.A kind of rare earth chitin, its chemical structure becomes:
It is by chitin
With rare earth L
aInstitute's coordination comprehensively forms under effects such as nonpoisonous organic solvent.The physics and chemistry value of measuring is:
| 1 | PH value | 4－7 |
| 2 | The CT molecular weight | 150-180 ten thousand |
| 3 | CT takes off the acetate degree | 80－85％ |
| 4 | The RE total content | 1.5% |
| 5 | Oxygen level | 1.4% |
| 6 | Solid content | 10% |
Its concrete preparation process is:
1.10kg chitin+300kg water;
2. in 1 solution, add 6 ‰-2% Glacial acetic acid 5kg constant temperature two hours under 70 ° of-80 ° of conditions;
3. in 2 solution, add rare earth element L
Ai, constant temperature two hours;
4. in 3 solution, add buffer reagent 1%KH
2PO
45kg adjusts pH value;
5. in 4 solution, add water 200kg;
6. in 5 solution, add linking agent.
7. synthetic, detection.
