Abstract
The invention discloses a zinc-rich modified-Chinese-chestnut-protein-coated slow-release fertilizer. The fertilizer is made from the following raw materials, by weight part, 29-31 of cocopeat, 1-2 of zinc sulfate heptahydrate, 2-3 of wheat gluten powder, 95-105 of fresh Chinese chestnuts, 3-4 of zinc lignocarbonate, 6-8 of potassium sulfate, 16-18 of wheat bran, 24-26 of fruits of ficus pumila, 1.7-1.8 of a glutamine transaminase preparation and a proper amount of water. The fertilizer is scientific and reasonable in component ratio; through addition of zinc lignocarbonate and zinc sulfate heptahydrate, abundant supply of zinc is ensured; and based on a scientific ratio of nitrogen to zinc and through use of organic chelation technology, it is ensured that crops can normally absorb zinc. The fertilizer has a slow-release effect, can supplement zinc to the crops for a long time, and has a good growth promotion effect on zinc-deficient soil and crops with high demand of zinc.
Description
Technical field
The present invention relates to slow release fertilizer technical field, particularly relate to a kind of zinc-rich modification Semen Castaneae protein envelope slow release fertilizer.
Background technology
Along with the specialization of China's agricultural production, industrialization, the development of scale, agricultural is constantly upgraded for the requirement of fertilizer, soil fertility, and conventional fertilizers is low due to plant recovery of nutrient, constrains the sustainable development of agricultural planting.The application of coated slow release fertilizer is then the effective way solving this problem.But the coated fertilizer of current common coated slow release fertilizer is to use the non-degradable high molecular polymer of chemosynthesis, easily remain in soil and cause soil degradation and pollution, the function singleness of coated fertilizer simultaneously, generally only there is slow controlled-release effect, do not account for the effects such as water suction, antibacterial, antioxidation and the practicality for different soils environment.
The rich in nutrition content of Semen Castaneae, there are substantial amounts of starch, protein, fat etc., contain multi mineral prime element simultaneously, the most important macroelement N, P, K, Ca etc. and trace element Fe, Cu, Zn, Mn etc., Semen Castaneae also has the functional component useful to plant growing, if the polyphenol substance in Semen Castaneae is a kind of natural antioxidant, gallic acid therein, ellagic acid, elladitannin have powerful antioxidation, antibacterial characteristics.In Semen Castaneae, protein content is high simultaneously, accounts for 5%-11%, rich amino acids in Semen Castaneae albumen, and plant can absorb aminoacid, therefore can improve the trophic structure in growing process, and potentiality to be exploited is very big.
Semen Castaneae albumen has preferable dissolubility and viscosity in the pH range of 7.0-8.0, and by combining the common effect of water, hydrodynamics water and Physical entrapment water, it is allowed to that there is fabulous moisture holding capacity, the number of dropouts of moisture can be reduced, the most in the basic conditions, Semen Castaneae albumen also has preferable emulsibility, foaming characteristic and foam stability, meets the condition needed for coated fertilizer in slow release fertilizer.
Zinc is a kind of important trace element in plant, suffers from important regulating and controlling effect for the regulation of plant growing, the growth of rhizome, to zinc deficient soil and need zinc crop to supplement Zinc nutrition with greater need for by fertilizer.
Semen Castaneae all has plantation, wide material sources in various places, utilizes the slow-release fertilizer that the exploitation of Semen Castaneae albumen is novel, gives the function that slow release fertilizer is new simultaneously, and the development for slow release fertilizer opens new approach.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of zinc-rich modification Semen Castaneae protein envelope slow release fertilizer.
The present invention is achieved by the following technical solutions:
A kind of zinc-rich modification Semen Castaneae protein envelope slow release fertilizer, is prepared by the raw materials in: coconut palm bran 29-31, zinc sulphate heptahydrate 1-2, wheat gluten flour 2-3, fresh Semen Castaneae 95-105, lignin zinc carbonate 3-4, potassium sulfate 6-8, wheat bran 16-18, Receptaculum Fici Pumilae 24-26, glutamine transaminage preparation 1.7-1.8, water are appropriate.
Specifically comprising the following steps that of described zinc-rich modification Semen Castaneae protein envelope slow release fertilizer preparation method
(1) cut into slices after going bud to shell fresh Semen Castaneae, pulverize levigate after drying at 48-50 DEG C, rice-chestnut powder is joined in the water of 10 times of its quality, and use 1mol/L sodium hydroxide solution to regulate PH to 9.8-10.0, through Ultrasonic Pulverization 16-17 minute under 35-40kHz, it is heated to 40-42 DEG C afterwards, is incubated 80-90 minute, cross leaching supernatant, after vacuum lyophilization, obtain Semen Castaneae egg albumen powder；
(2) step 1 is discarded Semen Castaneae bud, chestnut shell mixing is placed in calcining furnace; it is warming up to 540-560 DEG C with 20-25 DEG C/minute; take out after calcining 120-130 minute; obtain chestnut powdered carbon standby; again by coconut palm bran, wheat bran mixing retting fermentation; post-drying for the treatment of fully to become thoroughly decomposed is pulverized and mixes with lignin zinc carbonate, chestnut powdered carbon, is placed in pelletize in comminutor；
(3) squeeze the juice clean for the Receptaculum Fici Pumilae and filter, filtrate being mixed with zinc sulphate heptahydrate, is heated to 72-75 DEG C, be cooled to 40-42 DEG C and add potassium sulfate after stirring 5 minutes, be again stirring for 10 minutes, obtain nutritional solution standby；
(4) step 1 gained Semen Castaneae egg albumen powder is added in the water of 12-15 times of its quality, and regulate PH to 7.3-7.7 with 1mol/L sodium hydroxide solution, add glutamine transaminage preparation, wheat gluten flour, be heated to 50-53 DEG C, it is incubated 3-3.5 hour, obtains modified Semen Castaneae protein liquid；
(5) step 2 gained granule is placed in bottom and has in the cylinder of heater, barrel is heated to 55-60 DEG C, rolling process sprays into by the way of spraying sprays in cylinder step 3 gained nutritional solution, continue after having sprayed to roll 10-15 minute, spray into step 4 gained modification Semen Castaneae protein liquid again, continue to roll 10-15 minute, take out and i.e. obtain coated fertilizer granule of the present invention.
The invention have the advantage that
Semen Castaneae egg albumen powder acts on modification under the conditions of glutamine transaminage and alkalescence jointly, be conducive to the expansion of protein molecule, and catalytic proteins polypeptide generation intramolecular and intermolecular generation covalent cross-linking, it is embodied in viscosity to increase, there is higher shearing force repellence and gumminess, can stably be attached to fertiliser granulates surface, the retentiveness coordinating egg albumen powder ensures being dried of fertiliser granulates, will not make moist in short time disintegrate, extend action period, during slow release, albumin layer slowly decomposes, it is alternatively arranged as plant nitrogen source, and aminoacid-cation-polyphosphoric acid complex can be formed, reduce the mobility of heavy metal in soil ion, alleviate heavy metal ion to poison.Fertilizer component proportioning of the present invention is scientific and reasonable, the addition of lignin zinc carbonate, zinc sulphate heptahydrate etc. ensure that enough supplies of zinc, the nitrogen zinc ratio of science and the use of organic chelated technique simultaneously, ensure that the crop normal absorption to zinc, and the purpose of the long-term zinc supplement of crop it is issued at slow release effect, need zinc crop to have good growth-promoting effect zinc deficient soil and height.
