Description

A kind of sustained release fertilizer additive rich in trace element and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind of sustained release fertilizer rich in trace element and add Add agent and preparation method thereof.

Background technology

In nature, by known to the low-molecular-weight secondary metabolites of phytosynthesis and release just more than 100,000 kinds, its In volatile material just account for significant proportion, and there is certain " abnormal smells from the patient " mostly.This kind of material is as a kind of behavior hint Chemical signal play very important effect between plant and between plant and insecticide, anti-by chemical pesticide is cured the disease Insect pest not only breaks up environment, wastes resource, the main Drug resistance that also can improve crop pest and serious Pesticide Residue, The improvement affecting health insect simultaneously becomes more and more difficult.

The volatile material of plant belongs to the secondary metabolite of plant, typically distributes from leaf surface, plays and walks quickly and keeps away The effect of insect, is mainly derived from the fatty acid of plant, aminoacid and the metabolism of class phenylpropyl alcohol alkane, a series of by chloroplast Enzymatic reaction completes, and discharges, can be divided into 4 classes: isoprene, monoterpene, other active and secondary active substance in air, including Alkanes, alcohols, esters, phosphinylidyne class and acids, they form fatty acid derivant, aromatic compound, monoterpene and sesquialter Terpene compound, has the most antibacterial and anti-insect activity, may be directly applied to the Biological control of pest and disease damage.

The advantage that biological preparation prevents is: general disease pest is played avoidance effect, does not strangles, and does not destroy original Biological chain, so disease pest class will not produce resistance, is also a kind of protection to beneficial organism, a lot of the most this biological plant sources Active substance of plant belongs to the active substance of natural extract plant, does not have toxicity, is free from side effects human body, in soil Slowly volatilization, plays the effect of prevention, will be wholly absent after a period of time, make the agricultural product of plantation, quality more preferably, more strong Health.Easy to use, as long as adding soil with fertilizer or together with the adding ingredient of fertilizer, the larva of insect is typically all Being originated in soil, directly effect soil is best protection.

Summary of the invention

The present invention is in order to play certain prevention and control of plant diseases, pest control effect while improving crop nutrition content, and invention one has Keep away insect pest effect fertilizer additive, realize particular by the following manner:

A kind of sustained release fertilizer additive rich in trace element, it is characterised in that be made up of the raw material of following weight portion: propylene Acid 20 ~ 30, starch 5 ~ 8, N, N'-methylene-bisacrylamide 0.1 ~ 0.3, brassin lactones 0.5 ~ 0.9, garlicin 0.6 ~ 1.0, organic selenium 1.5 ~ 2.5, sodium selenite 3 ~ 6, potassium molybdate 5 ~ 8, cobaltous chloride 1 ~ 3, mineral nitrogen stone powder 2 ~ 5, zinc sulfate 7 ~ 10, amino Acid powder 12 ~ 16, (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate 2 ~ 5, plant source raw material 30 ~ 40 and appropriate water；

Described plant source raw material be with weight (part) be the unit fresh tomato leaf 3 ~ 6 of mixing, Folium seu Cortex Nerii 6 ~ 10, Folium Cinnamomi porrecti 8 ~ 12, Fructus Gleditsia 4 ~ 6, acer monoes 2 ~ 5, Pinus tabuliformis 10 ~ 15, ailanthus altissima (mill.) swingle 10 ~ 14 and Folium Ginkgo 7 ~ 12, after preliminary pulverizing, 0 ~ 5 DEG C of cold preservation is standby.

The preparation method of a kind of sustained release fertilizer additive rich in trace element, it is characterised in that include following Step:

(1) by plant source raw mill 40 ~ 60min uniformly slurry, ultrasonication prepares serosity, adds by material-water ratio 1:2 ~ 3 Entering distilled water diluting, employing steam reflux, extract, 2 ~ 3h must be rich in the aqueous solution of extracting solution；

(2) water of powder of amino acids and 3 ~ 5 times of its weight portions is mixed, be heated to 70 ~ 80 DEG C, after stirring, be sequentially added into Asia Sodium selenate, potassium molybdate, cobaltous chloride, zinc sulfate, insulated and stirred 40 ~ 60min carries out amino acid whose complexation, after completing and described in (1) Aqueous solution；

(3) ground 160 ~ 180 mesh sieves after mineral nitrogen stone powder being carried out thermal cracking, mix other following residual components being not directed to and add Entering to the mixed liquor described in (2), stirring dissipates；

(4) finally starch is added to the mixed liquor described in (2), heats up under water bath condition 75 ~ 85 DEG C and stir to starch gelatinization, Being sequentially added into acrylic acid and N, N'-methylene-bisacrylamide after being cooled to room temperature, 5 ~ 10min is in 60 ~ 70 DEG C of water-baths in stirring Reaction 1.5 ~ 2h, is dried at 70 ~ 80 DEG C after completing, finally grinds to form powder.

The material that invention is chosen has Folium seu Cortex Nerii, and its leaf contains the Cardiac glycosides materials such as folinerinum C, and toxicity is big, can kill Worm；Folium Cinnamomi porrecti, plant contains Camphora, monoterpene and sesquialter Monoterpenes, has anthelmintic paralysis effect；Semen Ginkgo, plant contains Folium illicii Lanceolati Acid, ginkegetin, sterols material, toxic, there is anthelmintic insecticidal action；Fructus Lycopersici esculenti, containing multiple Flavonoid substances and life The licopersicin etc. of alkaloids class, can cause insecticide deterrent, refusing to eat and intoxicating phenomenon；Other tree class blade has going back of this effect same There are Fructus Gleditsia, acer monoes, Pinus tabuliformis, ailanthus altissima (mill.) swingle；

Invent Fructus Lycopersici esculenti liquid as raw material, use distilled water lifting manipulation to obtain the water solublity crude extract in tomato leaf, mix chlorine cyanogen Chrysanthemum ester acts on Muskmelon Plants, and research extract, for the resistance effect of aphid, utilizes taking food of EPG instrument test aphid, Aphid and the plant that takes food thereof are accessed same circuit, and the lancet of aphid, as electrode, forms loop during very moment needle-penetration plant, Just have corresponding display, understand the situation that takes food of aphid with this, between test data sheet 1 ~ 10h aphid take food situation, send out Passage the most in time, aphid seldom or causes damage almost without to the blade of Fructus Melo at the beginning, and passage in time is sweet The blade of melon is compromised gradually, shows: the crude extract of Fructus Lycopersici esculenti can prevent the harm of aphid, crude extract anthelminthic effect to show Antifeedant upper, this active substance belongs to a kind of volatile material.

Invention is in order to be applied to reality the action time and action effect improving plant extract, it is necessary to ensure that store this Volatile active material belongs to the material of a kind of slow degraded, simultaneously because planting site is dried, rapid dehydration is likely to lead Cause volatile material lost efficacy or distributed too fast, do not have the effect of long-time protection, in the face of problem above is invented volatility Extracting solution is combined with resin-phase, uses acrylic resin, and it is the resin of a kind of high-hydroscopicity, and it connects with C-C simultaneously High molecular polymer, can be utilized by microbial degradations such as the staphylococcus in soil, streptococcus, can slowly discharge volatility and resist Worm material, is greatly prolonged protected effect.

Beneficial effects of the present invention: the additive of invention contains the trace element that various plants growth is useful, makes trace first Element mixing a great number of elements is used along, it is easy to cause absorbing uneven and wasting, and invention is before this by trace element and aminoacid Complexation, utilizes the plant priority to Amino Acid Absorption, improves the absorption of trace element, and trace element and resin-bonded exist simultaneously Together, slowly discharge while degrading with resin, increase operation rate, avoid waste and pollution to environment, resin decomposition same Time constantly can send the vegetable active anthelmintic ingredient of interpolation, it is also extraordinary that crop prevents pest and disease damage.
