Abstract
The invention discloses a natural compound-based soil conditioner, which belongs to the technical field of chemical pesticides. The natural compound-based soil conditioner comprises the following components in percentage by mass: 97 to 99 percent of wood vinegar or bamboo vinegar and 1 to 3 percent of chitosan. The invention is a chitonsan saline and alkaline soil conditioning liquid which can reduce the pH value of saline and alkaline soil, increase crop yield and improve the quality.
Description
Technical field
What the present invention relates to is a kind of product of chemical industry technical field of pesticide, specifically is a kind of soil improvement agent based on natural compounds.
Background technology
(Chitosan, CTS), molecular formula is (C6H11NO4) n to chitosan, is a kind of macromolecule cation saccharan, is the glycosaminoglycan that chitin is sloughed part second phthalidyl.Chitin has another name called chitin, chitin (Chitin), it extensively is present in the shell of multiple arthropods such as shrimp, crab and insect etc., also be the important component of lower animal such as fungus algae simultaneously, but also be the common component of fungal cell wall, with fungal cell's generation and keep and the formation of separating relevant, the realization of fungi growth and function is had special important meaning.About 10,000,000,000 tons of the annual chitin that generates of occurring in nature, at all natural polymers, reserves account for second, are only second to Mierocrystalline cellulose, are a kind of rich natural resource.
At present, discover that chitosan has broad application prospects in a plurality of fields such as medical science, biotechnology, chemical industry, food, agricultural, environmental protection.In agriculture production, be applied to aspects such as preserving fruit and vegetable utilizing, seed embedding, having now found that chitosan is manured into soil as soil improvement agent can suppress on the one hand the effect of pathogenic bacteria in the soil effectively, and the multiple disease resistance reaction of inducing plant promotes plant-growth.On the other hand, can with heavy metal complexings such as lead in the soil, chromium, and objectionable impurities such as toxic substances such as phenols, organic amine in can also adsorbent solution, thereby reduced the soakage of farm crop to toxic substance, reduce the indirect intake of people and animal, played good environment and safety benefit.For chitosan is distributed in the soil better, often chitosan is made colloidal solution and be manured into soil, make full use of good film-forming properties of chitosan and porous surface structure, improve the physicochemical character of soil.Chitosan only is dissolved in diluted acid because molecular weight is big, and water insoluble, this limits its purposes greatly.
Pyroligneous liquor is wood distillation or the condensate recovery liquid of firing thermal decomposition of wood composition in the charcoal process, is acid, and the composition complexity mainly is that organic acid, phenols, ketone, alcohols and lipid material are formed, and wherein is main component with acetic acid.Because wooden jealous woman mainly is made up of acetic acid, methyl alcohol and aldehydes matter, therefore make solvent with pyroligneous liquor, the dissolving chitosan is made liquid liquid soil conditioner, not only can reduce cost, reduce environmental pollution, and can increase the improved effect of soil, improve crop yield and quality.
Through new, do not find that as yet similar techniques is applied to the document or the report of this area to looking into of prior art.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of soil improvement agent based on natural compounds is provided, can reduce salt affected soil pH value, improve crop yield and improve the chitosan salt affected soil conditioning liquid of quality.
The present invention is achieved by the following technical solutions, and component of the present invention and mass percent thereof are: pyroligneous liquor or bamboo leachate 97%-99% and chitosan 1%-3%.
Described pyroligneous liquor or bamboo leachate be meant timber or bamboo through destructive distillation or fire the steam gas mixture that generates in the charcoal process through condensation, reclaim, leave standstill after, (upper strata is the dark oil composition to the translucent liquid product of russet in the middle of isolated, lower floor is thick tar ingredients), pH value 1.5-3.7, organic content 7-15%, wherein, acetic acid accounts for the 30-70% of organic content.
Described chitosan is meant that chitin sloughs the glycosaminoglycan of part ethanoyl, i.e. the one-level derivative of chitin, and its chemical formula is: (C
6H
11NO
4)
n
The present invention has the following advantages after realizing: 1, aboundresources, and with low cost; 2, turn waste into wealth, improved resource utilization; 3, improve soil physical chemistry performance and crop rhizosphere microenvironment effectively, be beneficial to crop and absorb mineral substance, promote the crop healthy growth, improve the yield and quality; 4 increase soil fertility, and save fertilizer amount, reduce production costs; 5, preparation is simple, easy to use.
