Description

A kind of improve plant heat resistance property, reduce heavy metal-polluted soil harm organic fertilizer

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of raising plant heat resistance property, reduce heavy metal-polluted soil harm Organic fertilizer.

Background technology

Agriculture and forestry produce in, use chemical fertilizer the most in a large number to improve yield, create therewith multiple environmental pollution and The problems such as soil degradation, bio-organic fertilizer destroys owing to will not produce environment and soil, is the fertilizer of a kind of green high-efficient, In plant growing, obtain quick development and be widely applied.But in the correlation technique of existing bio-organic fertilizer, right Its research is mainly concentrated in the aspects such as content and the utilization rate of raising Nutrient Elements in Soil, for the unfavorable side of body of environment Compel and the most deep the probing into of combination of other surcharges, it is impossible to fundamentally solve to improve plant products, make agricultural The problem producing ensured sustained development development.

There are some researches show, plant can cause reactive oxygen species to accumulate under the high temperature conditions, damages biomembrane, destroys chloroplast Etc. structure, cause chlorophyll mass fraction to reduce, and high temperature makes plant chlorophyll biosynthetic intermediate product amino ketones The biosynthesis of valeric acid and protoporphyrin IX is affected, and then chlorophyll growing amount is reduced, and meanwhile also results in thin Born of the same parents' membrane permeability strengthens, and malonaldehyde molality increases, Electrolyte Leakage, and natomical leaf structure changes, and then impact The growth promoter of plant, affects the accumulation of Biomass.

Lignum cinnamomi camphorae is as a kind of conventional economical seeds, rich in the materials such as Camphora, aromatic alcohol and salicylic acid, these things in its blade Matter not only has preferable inhibition to pathogen, moreover it is possible to the accumulation of proline in promotion plant, improves in blade solvable Property albumen mass fraction regulate osmosis system, maintain the stability of plant cell membrane, simultaneously can be by regulation and control antioxidation System affects the plant response to adverse circumstance high temperature stress, the enhancing of induction activities of antioxidant enzymes, thus reduces plasmalemma of plant Infringement, improve the plant resistance to hot environment.

Based on this, the present inventor is by being studied the combination of bio-organic fertilizer and plant high temperature resistance and visited Rope, it is provided that a kind of novel bio-organic fertilizer, for growth promoter and the use value tool of raising fertilizer of regulation plant There is important meaning.

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 raising plant heat resistance property, reduction soil The organic fertilizer of Heavy Metal Pollution.

The present invention is achieved by the following technical solutions:

A kind of improve plant heat resistance property, reduce the organic fertilizer of heavy metal-polluted soil harm, be prepared by the raw materials in: cotton Seedcake 38-42, biogas residue 13-15, activated carbon powder 4-5, carboxymethyl starch sodium 3-4, zinc sulfate 1-2, calcium hydrogen phosphate 3-4, Oryza sativa L. straw Stalk 39-41, Folium cinnamomi camphorae 28-30,30% hydrogenperoxide steam generator 9-11, tetradecyl trimethyl ammonium chloride 0.6-0.8,5mol/L hydrogen Sodium hydroxide solution is appropriate, 45% ethanol water is appropriate, water is appropriate.

The concrete steps of the described organic fertilizer preparation method improving plant heat resistance property, reduction heavy metal-polluted soil harm are such as Under:

(1) cottonseed cake, biogas residue mixing are placed in fermentation vat, add water to the 62-66% fermentation 2-3 week of fermentation heap maximum water holding capacity, Must be fermented after having fermented siccative and fermentation liquid by fermentation material squeeze and filter, then will collect bacterium mud after fermentation liquid centrifugal treating with clear Liquid, makes lyophilized powder by bacterium mud lyophilization standby；

(2) shred into broken section of 10-15 centimetre after being dried by rice straw, put into 5mol/L by solid-liquid ratio 1:6-8g/mL In sodium hydroxide solution, filter after being stirred continuously process 5-6 hour, with water rinse filtering residue to neutral, by filtering residue and ten after drying Tetraalkyl trimethyl ammonium chloride mixes, then is added thereto to the water of mixed material quality 10-12 times, is warming up to after mix homogeneously 40-42 DEG C, add 30% hydrogenperoxide steam generator, be stirred continuously reaction 180-200 minute, sucking filtration after completing, products in water is moistened It is washed till neutrality and dries at 50-55 DEG C and pulverize, obtaining modified water rice straw powder, by this powder and activated carbon powder, step 1 institute Must be fermented siccative and lyophilized powder mixing granulation, standby；

(3) fresh Folium cinnamomi camphorae is placed in the shady and cool place that is dried to dry in the shade, ground to form the powder of 50-70 mesh sieve with pulverizer, and by material Liquor ratio 1:16-20g/mL, by powder and the ethanol water mixing of 45%, is warming up to 58-60 DEG C and extracts 80-90 minute, and period is not Disconnected stirring, by four layers of filtered through gauze after having reacted, is evaporated the filtrate obtained, and obtains Folium cinnamomi camphorae extraction material standby；

(4) in step 1 gained clear liquid, add carboxymethyl starch sodium, zinc sulfate, be warming up to 67-73 DEG C and react 28-32 minute, it After be down to room temperature and add calcium hydrogen phosphate and step 3 gained Folium cinnamomi camphorae and extract material, stir to obtain nutritional solution, by nutritional solution with spray The mode that spray painting is coated with uniformly sprays in step 2 gained particle exterior surface, then is dried by pellet frozen, obtains fertilizer of the present invention Grain.

The invention have the advantage that

Active substance therein, by the extraction to Folium cinnamomi camphorae, is transferred in fertilizer, and utilizes rice straw by fertilizer of the present invention The cross layered multi-pore structure of the modified uniform sheet provided adsorb immobilized nutrient and camphor leaf extract, thus by this A little active substances are supplied to plant indirectly, can be increased plant leaf blade stomatal frequency by Osmoregulation, be reduced gas after absorbing Hole aperture and area, effectively keep absorbing moisture, and stop excessive water to evaporate, ensure that plant enters under the high temperature conditions simultaneously Row photosynthetic moisture supply, prevents dehydration from damaging plant, and then the thermostability of plant is greatly improved.

Fertilizer nutrient content of the present invention equilibrium comprehensively, cottonseed cake, biogas residue etc. organic interpolation after microbial degradation Metal ion distribution in soil can be diluted, the interpolation energy adsorptional earth of the adsorptivity raw material such as activated carbon powder, carboxymethyl starch sodium Remaining heavy metal in earth in a large number, passive metal ion, to the transport of overground part, has ensured the healthy growth of plant, has enhanced plant The toleration of heavy metal, reduces the adverse effect to plant.

Detailed description of the invention

A kind of improve plant heat resistance property, reduce the organic fertilizer of heavy metal-polluted soil harm, former by following weight portion (kg) Material is made: cottonseed cake 38, biogas residue 13, activated carbon powder 4, carboxymethyl starch sodium 3, zinc sulfate 1, calcium hydrogen phosphate 3, rice straw 39, Folium cinnamomi camphorae 28,30% hydrogenperoxide steam generator 9, tetradecyl trimethyl ammonium chloride 0.6,5mol/L sodium hydroxide solution be appropriate, 45% Ethanol water is appropriate, water is appropriate.
