Description

A kind of water soluble fertilizer with insecticidal function and preparation method thereof
Technical field
The present invention relates to water soluble fertilizer technical fields, and in particular to a kind of water soluble fertilizer with insecticidal function and its Preparation method.
Background technology
The current fertilizer in China is mainly a great number of elements, middle trace element and the mixing of additive, and micronutrient levels is few, And non-time-release fertilizer, fertilizer efficiency is poor, and accommodation is relatively narrow, and it is also limited to adapt to crop species.In recent years, as water-soluble fertilizer is in life Application amount in production is continuously increased, and the producting proportion of water-soluble fertilizer is unreasonable, and water-soluble fertilizer uses un-reasonable phenomenon increasingly convex It shows and, the production cost for water soluble fertilizer occur is high, and content is relatively low, particularly without insecticidal function, causes crop sick Worm is severe.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of water soluble fertilizer with insecticidal function and Preparation method.
To achieve these goals, the technical solution adopted by the present invention is as follows:
A kind of water soluble fertilizer with insecticidal function, is prepared by the raw material of following parts by weight:27-33 parts of chicken manure, biology 13-19 parts of charcoal, 5-7 parts of silica, 6-10 parts of calcium magnesium phosphate, 7-13 parts of diatomite, 4-6 parts of sodium alginate, concave convex rod 6-8 Part, 6-10 parts of S-Ethyl ethylthio sulfonate.
The above-mentioned water soluble fertilizer with insecticidal function, wherein, it is prepared by the raw material of following parts by weight:Chicken manure 30 Part, 16 parts of charcoal, 6 parts of silica, 8 parts of calcium magnesium phosphate, 10 parts of diatomite, 5 parts of sodium alginate, 7 parts of concave convex rod, S-Ethyl ethylthio sulfonate 8 parts.
The above-mentioned water soluble fertilizer with insecticidal function, wherein, contained N, P in the chicken manure2O5、K2The weight ratio of O is (1.2-1.8):(0.5-1.1):(0.4-0.6).
The above-mentioned water soluble fertilizer with insecticidal function, wherein, the charcoal is stalk or sawdust.
The preparation method of the above-mentioned water soluble fertilizer with insecticidal function, includes the following steps:
(1)It is 5-40 microns that the diatomite, silica, concave convex rod of above-mentioned parts by weight are crushed to grain size respectively;
(2)The chicken manure of above-mentioned parts by weight, charcoal suitable quantity of water are placed in semiclosed fermentation tank, utilize turning over for machine mixer Action is used, and ferments 14-16 days to get zymotic fluid;
(3)In step(2)Calcium magnesium phosphate, sodium alginate, S-Ethyl ethylthio sulfonate and the step of above-mentioned parts by weight are added in obtained zymotic fluid Suddenly(1)Diatomite, silica, concave convex rod after middle crushing, it is dry after stirring evenly, pulverize to get.
Containing abundant n-p-k element and organic matter in chicken manure, and it is fertilizer without chlorine element in the formula of the present invention Main material, the dosage of chemical fertilizer can be effectively reduced, reduce cost, moreover it is possible to increase the fertility of soil;Charcoal is to lack It is formed under the conditions of oxygen by high temperature pyrolysis biomass, in alkalinity, pH ranging from 8.0-13.0, the basic group that charcoal contains Group, proton that can be in sweetening of the soil increases soil pH, and the acid-base value of soil is dominated by base cation, biology Containing more base cation in charcoal, into soil after proton and aluminium ion in commutative soil, so as to reduce its concentration, carry In addition to this high degree of base saturation and the pH value for adjusting soil, can also improve the carbon of soil in acid soil using charcoal Library promotes soil quick-effective phosphor, potassium and effective nitrogen content, enhances soil fertilizer ability, improves plant growth environment;Silica is A kind of acidic oxide, corresponding hyrate is silicic acid, can reduce the content of Cd in soil;Calcium magnesium phosphate is a kind of lemon of alkalinity Lemon acid-solubility phosphate fertilizer, dissolubility is good in acid soil, can form mixed metal phosphate by precipitation with Cd, Pb, Zn, and And calcium, the magnesium elements that calcium magnesium phosphate contains in itself play plant absorption heavy metal certain antagonism;Diatomite has more Permeability has extremely strong physical absorption and ion-exchange performance, is good soil conditioner;Sodium alginate is a kind of bonding Agent can increase viscosity and adhesion, reduce the loss of ingredient;Concave convex rod can adsorb the heavy metals such as Pb, Cd, Hg, As, Ni, The validity of heavy metal-polluted soil is reduced, so as to improve the PH of soil;S-Ethyl ethylthio sulfonate is also known as O-Ethyl ethanesulfonothioate, is a kind of plant Source bionic pesticide is the ethyl homologue of edible garlic extract allicin, sterilizes spectrum width, low toxicity, high volatility.
Chicken manure is primary raw material in water soluble fertilizer provided by the invention with insecticidal function, mainly provides N, P, K, raw Object charcoal mainly provides inorganic mineral components, delays fertilizer nutrient release in the soil, the loss for reducing fertilizer nutrient, titanium dioxide Silicon mainly provides silicone content, reduces the content of Cd in soil, and calcium magnesium phosphate reduces the content of Cd, Pb, Zn in soil, concave convex rod energy Enough heavy metals such as absorption Pb, Cd, Hg, As, Ni reduce the validity of heavy metal-polluted soil, so as to improve the pH of soil;S-Ethyl ethylthio sulfonate Can kill except the pest in soil, and by add sodium alginate can by other raw materials adsorb it is diatomaceous it is porous in, more Added with conducive to absorption of the diatomite to other raw materials, be conducive to slow release effect, enhance fertilizer efficiency.
Water soluble fertilizer provided by the invention with insecticidal function can increase the soil organism, improve soil fertilizer Power realizes weight-reducing synergy, improves the pH value of soil, effectively repairs, improves soil texture, reduces the effective dense of heavy metal in soil Degree while improving crop disease-resistant anti-adversity ability, effectively murders the pest in soil.
