Abstract
The invention discloses a novel special fertilizer for rice, relating the technical field of production of agricultural fertilizer. The novel special fertilizer for rice is formulated from the materials in parts by weight as follows: 70-76 parts of organic matter, 3-5 parts of potassium chloride, 12-13 parts of urea, 2-3 parts of monoammonium phosphate, 2-5 parts of talcum powder, 2 parts of trace elements, 1-2 parts of silicon fertilizer, 1-2 parts of microbial strains, and 1 part of envelope cementing agent. The novel special fertilizer for rice has the characteristics that usage as well as pollution to environment can be reduced, quick effect and long-effect time can be combined, and the novel special fertilizer can be used as the base fertilizer for rice.
Description
Technical field
The present invention relates to the agricultural fertilizer production technical field, particularly a kind of novel paddy rice-dedicated fertilizer.
Background technology
The content of nitrogen phosphorus potassium, it is the most important index of fertilizer efficiency, from existing fertilizer practice, execute the fertilizer in the ground, run off about 60% or by soil fixing, polluted underground water or become the fertilizer of invalid attitude, the fertilizing method of long-term irrationality in addition causes in various degree destruction to soil, environment, farm crop.In the last few years, some sustained-controll-release fertilisers occur, and can slow down disengaging of effective ingredient in the fertilizer, reduced the loss of effective ingredient.As Chinese patent (number of patent application is 200810012388.1) " the slow controlled release type organic inorganic block manure that a kind of root is used; its method for making and application ", be with peat, feces of livestock and poultry, crop straw, rice husk, Pericarppium arachidis hypogaeae, brown coal, weathered coal, coconut husk, the coconut palm chaff, pomace, mushroom residue, organic materials and nitrogen such as discarded edible mushroom culture medium, phosphorus, potassium, micronutrient element and components such as nutrient inhibitor are pressed into organic-inorganic piece type fertilizer after according to different plant nutrition demand rational proportions, this product is applied to the bottom of seed or transplanting seedling, be wrapped in plant root with the plant root growth, can form root and concentrate the fertilising system, improve the contact area of root system and nutrient, make plant root efficient absorption nutrient, nutrient is difficult for running off, fertilizer efficiency period is long, can effectively improve fertilizer utilization efficiency, reach accurate fertilising purpose.Chinese patent (number of patent application is 200510033316.1) " clay mineral controlled releasing fertilizer and production technique thereof " and for example, by compound fertilizer, clay mineral sustained release dosage and water salt binding agent are made through raw material metering → raw material mixing → raw material pulverizing → mixing granulation → fine powder coating → baking and curing → cooling screening → ultrafine powder capsule polishing → primary products → metering blending → finished product packing, it is simple to have production technique, cost of development is low, nuisanceless, the chemical fertilizer utilization ratio height, be widely used, lower-price characteristic, can make such as the super hybridized rice controlled release special fertilizer, extraordinary grain quality rice controlled release special fertilizer, the common rice controlled release special fertilizer, the tealeaves controlled release special fertilizer, the fruit tree controlled release special fertilizer, multiple dedicated fertilizers such as decorative flower controlled release special fertilizer, the needs that can be suitable for the various plant husbandry in Chinese vast rural area are a kind of more satisfactory dedicated fertilizers.
Summary of the invention
The object of the present invention is to provide and a kind ofly both can reduce fertilizer amount, reduce pollution, have the quick-acting and long-acting paddy rice-dedicated fertilizer that combines again environment.
The technical solution used in the present invention is a kind of novel paddy rice-dedicated fertilizer of invention, is that the preparation of raw material by following weight share forms:
Organism 70-76 Repone K 3-5 urea 12-13
Trace element 2 among the monoammonium phosphate 2-3 talcum powder 2-5
Siliceous fertilizer 1-2 microbial strains 1-2 coating cementing agent 1.
The technical scheme one of its optimization is that the preparation of raw material by following weight share forms:
Organism 70 Repone K 4 urea 13
Trace element 2 in monoammonium phosphate 2 talcum powder 5
Siliceous fertilizer 2 microbial strainss 1 coating cementing agent 1.
The technical scheme two of its optimization is that the preparation of raw material by following weight share forms:
Organism 76 Repone K 3 urea 12
Trace element 2 in monoammonium phosphate 2 talcum powder 2
Siliceous fertilizer 1 microbial strains 1 coating cementing agent 1.
The technical scheme three of its optimization is that the preparation of raw material by following weight share forms:
Organism 72 Repone K 5 urea 12
Trace element 2 in monoammonium phosphate 3 talcum powder 2
Siliceous fertilizer 1 microbial strains 2 coating cementing agents 1.
In above-mentioned each technical scheme, described organism is: the chicken manure after the fermentation also can be fermentation afterwards ight soil or the human excrement of other animal.
In above-mentioned each technical scheme, described middle trace element comprises: a kind of element in sulphur, magnesium, calcium, zinc, boron, copper, manganese, iron, the molybdenum or multiple element or whole, its consumption can be equal portions, also can adopt other ratio.
In above-mentioned each technical scheme, described siliceous fertilizer comprises: one or more in iron slag, yellow phosphorus slag, flyash equal industrial residue, silicon ore, the water glass or whole, its consumption can be equal portions, also can adopt other ratio.
In above-mentioned each technical scheme, described microbial strains comprises: a kind of bacterium in vinelandii, phosphate solubilizing bacteria, potassium solubilizing bacteria, the actinomycetes or multiple bacterium or whole, its consumption can be equal portions, also can adopt other ratio.
In above-mentioned each technical scheme, described coating cementing agent is: clay-polyester mixed polymer coating cementing agent.
The preparation method of novel paddy rice-dedicated fertilizer of the present invention is as follows: at normal temperatures and pressures, described organism, Repone K, urea, monoammonium phosphate, talcum powder, middle trace element and siliceous fertilizer are pulverized by pulverizer earlier, then after the mixing and stirring, enter in the material separating disc, by the extrusion machine granulation, again by spraying clay-polyester mixed polymer jointing compound coating, dry, sieve, and be transported in the batch mixing dish by conveying belt, add described microbial strains again and mix, the gained granular substance is novel paddy rice-dedicated fertilizer product of the present invention.
Novel paddy rice-dedicated fertilizer of the present invention is the compound fertilizer of a kind of low nitrogen, phosphorus, potassium content (8%≤total nutrient<15%), and its fertilizer amount is less.Simultaneously, adopt clay-polyester mixed polymer jointing compound coating, form slow release effect, thereby, both had the quick-acting and long-acting characteristics that combine, can reduce the loss of effective ingredient in the fertilizer again, reduce pollution to environment.In addition, also be added with microbial strains, after being manured into soil, formed microorganism beneficial bacterium population can be improved soil, continues to build up fertility; And, by microorganism fixed nitrogen, phosphorus decomposing, potassium decomposing activity, from air and soil, npk nutrient can be obtained, thereby the demand of crop can be guaranteed nitrogen phosphorus potassium, really have the effect of abridged edition, high-yield, efficient, environmentally friendly.
Novel paddy rice-dedicated fertilizer of the present invention, its fertilizer efficiency is very remarkable, and test shows 2009-2010 on Hunan Province's Yongzhou City Dongan County, Lengshuitan District and other places, good absorption, instant effect, not only abridged edition but also high yield, output obviously improves, and paddy rice is on average increased production 10-21%.
