Abstract

This invention discloses a new type of composite fertilizer. The composite fertilizer is composed of the insecticide extracted from Melia azedarach, Daemonorops margaritae, Eucalyptus globules and tobacco leaves, and urea, ammonium phosphate, potassium chloride, sulfur and rare earth metals. The composite fertilizer can also comprise such trace elements as B, Zn, Cu and Fe. The composite fertilizer can be used on cotton and wheat, and can effectively prevent army worms and paddy rice borers.

Description

A kind of new type compound fertilizer and production method thereof

One, technical field

The present invention relates to a kind of new type compound fertilizer and production method thereof.

Two, background technology

Rare earth is the abbreviation of rare earth element, and existing a series of experiment proves that tentatively rare earth element has the crop of promotion and takes root, germinates, increases chlorophyll, improves crop yield, improves effects such as product quality and reinforcement crop anti-adversity ability; Trace elements such as boron, zinc, copper can provide crop growth necessary nutrition, promote plant growth, growth, improve the yield and quality of crop.In azophoska, add these elements, can more fully provide essential nutrition, promote the growth of crop to crop.

Plant is the natural treasure-house of bioactive compounds, and the meta-bolites of most its generations has insecticidal activity.Discover that the extract of China tree, herba fibraureae recisae, eucalyptus leaves, tobacco leaf all has parasiticidal effect, and these plants all have distribution widely in China, the extraction of its effective insecticidal constituent is simple and easy to do, obtains easily.The definite effect of plant-derived sterilant is reliable, the harmful organism resistance that can also avoid the chemical pesticide life-time service to bring after the application, drawbacks such as residual toxicity and environmental pollution.

This novel composite fertilizer that adds plant-derived sterilant and form in fertilizer can not only provide competent nutriment to crop, can also strengthen the ability of its disease and insect resistance.

Three, summary of the invention

Moiety as compound manure, urea, phosphorus ammonium, Repone K, rare earth and sulphur all can be buied by the market, urea, phosphorus ammonium, Repone K that the present invention selects for use Shandong Luxi Chemical Industry Co., Ltd to produce, the SULPHUR POWDER that Lianyun Harbour star Industrial Technology Co., Ltd provides, the compound rare-earth element that Inner Mongol Rare Earth Company provides.Critical step is China tree, herba fibraureae recisae, eucalyptus leaves, tobacco leaf are carried out the extraction of effective insecticidal constituent.

The effective insecticidal constituent of China tree mainly is a Toosendanin.Extraction process: amargosa bark, fruit oven dry, pulverize, add 95% industrial spirit sealing and soaked 48 hours, leach alcohol after, the submergence of reprocessing industry alcohol, sealing was soaked 24 hours, leach alcohol liquid, repeat 3 times after, merge the alcohol liquid leach, be concentrated into chocolate thickness paste one by one with Rotary Evaporators, promptly obtain extract.

Herba fibraureae recisae (trypterygine) is insecticidal constituent trypterygine total alkali effectively.Extraction process trypterygine alcohol reflux obtains ethanol extract, adds the water mixing, gets its throw out, the airing abrasive dust, and the hydrochloric acid filtration with 50ml/g transfers to 8～9 with NAOH with pH value, filters the precipitation that obtains and washes once, is thick trypterygine total alkali after the drying.

Effective insecticidal constituent of tobacco is nicotine (Nicotine).Extraction process: tobacco leaf is processed into fine powder, adds milk of lime, make pH value transfer to 8～10, nicotine then dissociates out, adds kerosene then and extracts filtration, comes out in solvent with sulfuric acid again, is nicotine.

The effective constituent of folium eucalypti is eucalyptus oil.Extraction process: folium eucalypti distills with steam distillation, uses anhydrous sodium sulfate dehydration again.

Vegetable insecticide and urea, monoammonium phosphate, Repone K, rare earth, sulphur proportionally 5～25%, 10～30%, 20～30%, 15～25%, 5～25%, 5～15% are measured; enter pulverizer and be crushed to 30～50 order fine powders; add in the stirrer and stir, be delivered in the tablets press after can stirring in about 5 minutes.Material after the pulverizing enters in the interior pelletizing disks of tablets press, and rotating-disk drives material and rotates, and adds hot water uniformly, makes material reunion granulating.Granulating working procedure requires raw material granularity 30～50 orders, and water ratio≤12% should be controlled wet grain water ratio≤15%, wet grain diameter 1.0～5.5mm, and shaping rate 〉=85%, prilling temperature are controlled at about 50～70 °.The wet granular material that is shaped from tablets press enters the rotary dryer oven dry, adjust in dry mixing wind-warm syndrome degree to 75～150 ℃, discharge port become containing of heat exchange wet dust-laden tail gas then by blower fan introduce send after the centrifugal scrubber dedusting outdoor.Material after the oven dry reduces temperature through overcooling, improves particulate intensity and outward appearance.Dry cooled particle can produce fragmentation, with particle through vibratory screening apparatus with diameter＜2.0mm and＞material of 5.0mm returns broken 1 preface pulverize after granulation again.Diameter then is packaged into the packing of 1kg, 25kg, 50kg at the particle of 2.0～5.0mm.

Different needs according to area, soil and crop can add trace elements such as boric acid, zinc sulfate, copper sulfate when granulation.

This composite fertilizer can work as base manure, can work as to topdress again and use.The contrast experiment who cotton and wheat is done according to imperial city, Linzi District town shows, under the equal conditions, use the experimental group of this composite fertilizer to compare with the blank group of not using composite fertilizer than the control group of using common Nitrogen, Phosphorus and Potassium, per mu yield cotton amplification is respectively 10.1% and 20.2%, per mu yield wheat amplification 12.3% and 15.6%.After using as base manure, can alleviate the harm of insect to seedling, especially mythimna separata and snout moth's larva are lacked pesticide 2～3 times than control group.

The used production unit of the present invention provides by Shen, Wuxi China equipment company limited, and concrete specification and parameter see Table 1

Four, embodiment

After embodiment 1 measures mixing with urea, monoammonium phosphate, Repone K, vegetable insecticide, sulphur, rare earth according to 15%, 25%, 20%, 20%, 10%, 10% ratio; enter pulverizer and be crushed to 30～50 purpose fine powders; add in the stirrer and stirred 5 minutes; enter the granulating disc granulation; the temperature of granulation is 60 ℃; water ratio is controlled at 10%, wet grain diameter 3.0～5.0mm, and shaping rate has 88%.The fine particle material enters rotary dryer and carries out drying, and the temperature of dry-heat air transfers to 100 ℃, and the material after the oven dry is through the cooling of revolution cooler.Dry cooled particle sieves the cut-off footpath becomes 25kg at the granule packaging of 2.0～5.0mm packing behind vibratory screening apparatus.

According to 15%, 25%, 20%, 15%, 10%, 15% mixed, other steps are identical with example 1 with the ratio of raw materials such as urea, monoammonium phosphate, Repone K, vegetable insecticide, sulphur, rare earth for embodiment 2.

Embodiment 3 adds compositions such as zinc sulfate, copper sulfate, boric acid on the basis of example 1 or 2, its ratio accounts for 1%.
