Description

A kind of salt affected soil engineered protein peptide fertilizer

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of salt affected soil engineered protein peptide fertilizer.

Background technology

21 century, China has totally entered quickening reclaiming traditional agriculture, walks the critical period of distinct Chinese characteristics agricultural modernization path.Utilize modern science to find effective technology, improve soil microenvironment, increase soil fertility, promote that plant efficient grows fast, thus increase crop yield, reach the object of ecological benefits, economic benefit and social benefit balanced development, there is very important and extremely urgent meaning.

Traditional fertilizer is in the process of coming into force, needing to produce the protein matters decomposed in fertilizer such as acidity, Sumizyme MP, trypsinase by microorganism is protein peptide, be converted into the acid of helium base again to be utilized by plant, its process consumed energy, the time is very long; Protein peptide then spans this process, and protein peptide directly can be converted into amino acid and be used by microorganism, thus accelerates the amount reproduction of microorganism.Prolific metabolite such as microbes secretion microbial polysaccharide, organic acid etc., improves soil water-retaining and holds fertilizer, ventilation and regulate cold and hot ability.Same urea, composite fertilizer etc. compare, and protein peptide can not spoiled soil and surrounding enviroment thus affect Agro-ecology balance, and fertilizer efficiency is more lasting, uses convenient and simple, can meet the demand of plant-growth animated period to nutrient.

Therefore, the present inventor utilizes and produces waste residue almond slag to extract protein peptide, and provides a kind of protein peptide fertilizer for the transformation of salt affected soil, to providing a kind of technical support to the scientific of agricultural.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides a kind of salt affected soil engineered protein peptide fertilizer.

The present invention is achieved by the following technical solutions:

A kind of salt affected soil engineered protein peptide fertilizer, is made up of the raw material of following weight part: phosphogypsum 9-12, feldspar in powder 6-8, borax 3-4, cottonseed cake 50-55, clay 18-22, poly-propionic acid amide 1-2, almond slag 105-120, iron protochloride 2-3, L-glutamic acid 1-2, water glass 4-6, calcium chloride 1-3, water are appropriate.

The concrete steps of the preparation of described fertilizer are as follows:

(1) put into 90-100 DEG C of water after being mixed by almond slag and soak 5-6 minute, with pulverizer, almond slag is fully pulverized after taking out drying, then the normal hexane adding crushed material 10 times of volumes stirs, soak 8-10 hour afterwards, use vacuum pump suction filtration again, obtain defatted seed flour, for subsequent use;

(2) in step 1 gained defatted seed flour, add the phosphoric acid buffer of 10 times of quality and regulate PH to be 9.0, after mixture being heated to 50 DEG C, lixiviate 75-85 minute, afterwards with 4500 revs/min of centrifugal 14-16 minute, obtaining supernatant liquor regulates PH to be 4.3-4.7 again, again with 4000 revs/min of centrifugal 5-7 minute, removes supernatant liquor post-drying, obtain protein peptide powder, for subsequent use;

(3) phosphogypsum, cottonseed cake, clay mixing are placed in compost pond and ferment, and every turning in 4-5 days once, compost middle portion is translated into outside, and add water in good time and ensure that compost is dampness, by gained drying materials after having fermented, and mix with feldspar in powder, borax and pulverize, make spheroidal particle by tablets press, for subsequent use;

(4) being heated to 65-75 DEG C by adding 5 times after poly-propionic acid amide, iron protochloride, L-glutamic acid mixing to the water of its quality, repeatedly stirring after 20-30 minute and being cooled to room temperature, obtaining chelating amino acids ferrous solution, for subsequent use;

(5) water glass and calcium chloride mixed and add 1.5 times to the water of its quality and be heated to 50-55 DEG C, after uniform stirring 12-15 minute viscous fluid is for subsequent use;

(6) mode of step 4 gained chelating liquid spraying spraying is evenly sprayed in step 3 gained particle exterior surface, again by the uniform broadcasting of step 2 gained protein peptide powder outside particle, treat that protein peptide powder is all attached to particle surface post-drying, and step 5 gained mucus is coated on particle exterior surface, and again dry, obtain fertiliser granulates of the present invention.

Advantage of the present invention is:

Use water glass and calcium chloride mixed solution to carry out coated in preparation process, due to its molten some surface temperature in a little higher than summer, can not dissolve easily, therefore there is good slow releasing function.

Particle exterior surface from outside to inside main composition is respectively calcium ion, protein peptide and chelates ferric ions, play induction root development and cell fission, nutritional supplementation, the photosynthetic work of enhancing improve the effect of metabolic capacity respectively, to the inducing action played in proper order of growing of plant, facilitate the quick growth of plant.

Fertilizer of the present invention is applicable to salt affected soil, the interpolation of cottonseed cake, clay etc. effectively can improve Soil structure, thus provide better growing conditions for microorganism and plant growth, the poly-propionic acid amide added significantly improves the water-retentivity of fertilizer, and reduce the nutrient loss that heavy irrigation causes, long-term application fundamentally can improve edatope, reduce the saltiness of soil, strengthen the activity of Soil Microorganism and enzyme, promote plant root growth, realize the object on transformation salinity ground.
