Technical background:

At present, crops are being used various liquid fertile, and as foliage fertilizer, ammino acid liquid fertilizer, micro-liquid fertilizer etc., some aspect of these fertilizer is better than traditional fertilizer and single chemical fertilizer.But because the negative effect that long-term a large amount of applying pesticides and chemical fertilizer bring can't be eliminated for the moment.(as soil compaction, the decline of the single salt murder by poisoning of plant, crop yield and quality.) the particularly serious influence that is agricultural chemicals, chemical fertilizer to ecotope, causing the insect mortality, the chitin of the short long required insect secretion of plant growing reduces in a large number, has directly influenced the healthy growth and development of plant.Chitin is described as the 6th human biological element by American-European scientist.Modern's eaten food is too meticulous, original few chitin, and agricultural product lose part again in process, and people have generally reduced the picked-up to chitin like this.Health has also been caused influence in various degree.Though the negative effect of existing liquid fertile no chemical fertilizer.But lack the chitin to plant growing, for this reason, people press for a kind of Agrotechnical formulation that had not only had the negative effect of agriculture chemical but also made the crops healthy growth.

In existing or disclosed technology, more by the Agrotechnical formulation that plant leaf surface uses, as trace element fertilizer, composite amino acid fertilizer, plant growth promoter, bactericide or the like.JP 2000-212013A has described a kind of inhibitor with antifungic action that contains aqueous solution shitosan, salicylic acid, acetyl magnesium and saleratus: JP 2000-128711A has described a kind of agricultural and gardening disease inhibitor that comprises water soluble chitosan, salicylic acid and salicylic acid analog; US 5,374, and 627 to have described a kind of molecular weight be 10,000-50,000 the chitosan hydrolyzate thing and the composition that is used to prevent and treat some crop pest of acetate; RU214768A has described a kind of composition of preventing and treating rice blast, and it contains molecular weight is 800-50,000 and degree of deacetylation be shitosan, lactic acid, succinic acid, potassium metasilicate, dimethyl sulfoxide (DMSO) and the water of 70-90%; EP878129 has described the composition of a kind of increase to the plant disease resistance, and it comprises molecular weight is that 800-15000 and degree of deacetylation are shitosan, lactic acid and the succinic acid etc. of 65-97%; Chinese patent application CN01122696.X discloses " a kind of preparation of shitosan health plant growth promoter and technology ", it is base-material with the shitosan, with the mineralized water is carrier, be equipped with acetic acid, lecithin, composite aminophenol powder, rapeseed oil, steviol glycoside etc. are to have the foliage fertilizer that promotes the plant growth effect; CN01123508.X discloses " a kind of agriculturally useful compositions that contains water soluble chitosan "; said composition contains low-molecular-weight and degree of deacetylation greater than 75% shitosan and non-toxic organic acid, Choline Chloride, betain, light rare earth, amino acids, vitamins, monoethanolamine, trace element etc., also has the effect that promotes crop growth.There is following defective in these Agrotechnical formulations: (1) function singleness; (2) functional effect a little less than; (3) contain the friendly organic synthesis composition of non-ambient.Also have multinomial Chinese patent to relate to the preparation method of green disinfectant chlorine dioxide, be used for the sterilizing prevent disease of crops, though environmental protection, function singleness, use cost height.

Summary of the invention:

The objective of the invention is to overcome the shortcoming that exists in the prior art, aim to provide chitin and derivative thereof that the modification of the antibiotic intensifier chlorine dioxide of a kind of usefulness comes from ocean crust biology, be aided with the manufacture method that the general nutrient component preparation of plant is used for the strong antibiotic multifunction marine organisms Agrotechnical formulation of plant sterilization again.

Chitin and derivative thereof are described as the 6th vital principle, and this marine organisms cellulose is very easy of plant absorbing, has strengthened physiology, the biochemical function of plant.Plant vigor strengthens, and helps promoting the plant health growth, and for there not being insects secretion chitins such as honeybee, butterfly, the greenhouse growing plants, as booth vegetable etc., it is important to seem more, and it not only has resistant effect, the effect of increasing production of applying fertilizer in addition.

It is generally acknowledged that when plant was subjected to extraneous infringement and pathogen and infects, chitin and derivative thereof can inducing plant produce a series of defense responses to be protected and self avoid further injury, and the generation disease resistance.Can excite the material of the defense response of plant to be called exciton.Its effect is just as our usually said vaccine.The exciton of denier just can excite strong disease resistance response takes place in plant or the cell, produces and accumulation disease resistance material (also claiming protective plant protecting agent).Chitin and deacetyl chitin are the main components of the shell of crustacean, also are the constituents of multiple fungal cell wall.Crust oligosaccharides (oligochitin) and chitosan oligosaccharide (oligochitosan) are exactly the plant exciton.Though chitin oligo saccharide and chitosan oligosaccharide inducing plant produce the machine-processed not clear of resistance.But the effect that its inducing action makes plant produce antibody enemy disease resistance has obtained the confirmation of many scientific researches.This becomes chitin derivative and is used for the theoretical foundation of marine organisms with agent.

But regrettably, though chitin and derivative thereof have certain antibacterial action, but it is subjected to the influence of environment very big, antibacterial effect does not far reach sterilization effects, this make it at present Agrotechnical formulation under the trend of multifunction, high efficiency, environmental friendliness development, seeming, major function is not enough, thereby has influenced applying of it.Chlorine dioxide is the environmentally friendly sterilized disinfectant that is called as 21 century.Have wide spectrum, efficient, green advantage.Many aspects such as agricultural have been begun to be used for.But exist independent function of use very single, labour intensity is big, and defective such as effective drug duration is short.

In order to realize the foregoing invention purpose, the main component of the inventive method prepared preparation comprises deacetyl chitin and derivative thereof, chlorine dioxide, auxiliary element nutrient for plants; Elder generation is mixed with deacetyl chitin and derivative thereof 1%～10% weakly acidic solution or neutral solution, under stirring condition, slowly add chlorine dioxide component reaction 20～90 minutes, add nutrient for plants again and stir and promptly make the marine organisms Agrotechnical formulation, deacetyl chitin and derivative thereof account for 0.0001%～30% in its preparation; Chlorine dioxide accounts for 0.001%～30%; General nutrient for plants accounts for 0.1%～40%; Surplus is other solvents such as water, is weight ratio; Total solids content is 0.0001%～100%.Wherein employed deacetyl chitin and derivative thereof comprise deacetylation be 10%～100% take off acetyl crust quaternary ammonium salt shitosan, shitosan carboxylate; And quaternary ammonium salt shitosan and shitosan carboxylate can be selected sodium salt, sylvite, ammonium salt, magnesium salts, calcium salt, zinc salt, mantoquita, molysite, molybdenum inflammation, silver salt etc.; Employed chlorine dioxide component comprises chlorine dioxide, aqueous solution of chlorine dioxide, solid-state stabilizing chlorine dioxide, the recessive body of chlorine dioxide etc.; And the recessive body of chlorine dioxide comprises chlorite and chlorate, and salt refers to sodium salt, sylvite, ammonium salt, magnesium salts, calcium salt, zinc salt, mantoquita, molysite, molybdenum salt, silver salt etc.Employed auxiliary element nutrient for plants can be selected chemical fertilizer commonly used, comprise nitrogenous fertilizer, potash fertilizer, phosphate fertilizer, amino acid and its esters, humus and its esters, also comprise trace elements such as sodium, potassium, ammonium, magnesium, calcium, zinc, copper, iron, molybdenum, boron, selenium, rare earth.Prepared strong antibiotic multifunction marine organisms Agrotechnical formulation can be by the sterilizing disease-preventing and the fertilising volume increase that plant leaf surface are sprayed, form such as root pouring is used for each plant species.Its auxiliary element nutrient for plants can use for multiple simultaneously for single the kind also.

Chitin and derivative thereof and chlorine dioxide reaction can make chitin and derivative thereof degrade gradually, and biologically active significantly improves; Chitin and derivative thereof are the natural marine organism macromolecular materials, and its special structure has stronger absorption stability effect to chlorine dioxide, have overcome the disadvantage of the volatile inefficacy of chlorine dioxide on largely.So the reactant of chitin and derivative thereof and chlorine dioxide has the effect of the other side's function of mutually promoting, and promptly has synergistic effect.On this basis, needs according to the nutrition of crop classification, comprise the general nutrients of plants such as trace element such as nitrogenous fertilizer, potash fertilizer, phosphate fertilizer, amino acid and its esters, humus and its esters, sodium, potassium, magnesium, calcium, zinc, copper, iron, molybdenum, boron, selenium, rare earth element on composite, make the biological Agrotechnical formulation of this novel sea have the killing action very strong to fungi, virus and common pathogen, better to the control efficiency of plant disease.On the other hand, because chitin and derivatives active thereof significantly improve, the easier absorption of plant, " protective plant protecting agent " effect is better, and the fertilising effect of increasing production improves.
