Abstract
The invention is concerned with the plant growth regulator with water-solubility chitosan, which is with the water-solubility oligo-chitosan (the molecular weight <10000, 0.5% -10%), the solubilizer (alkylphenol ethoxylates, 0.01% - 1%), the synergist (urea or urea phosphate, 1% - 10%), and the sylvin aqueous solution. The preparation method is: the high molecular weight chitosan oxidation and degradation by degradion agents (NaNO2, H2O2 or NaClO), prepares with the solubilizer, the synergist and the sylvin to be the plant growth regulator without separation. The invention can active the plant cell, improve the fruit quality, which is fit for vegetable, fruit tree and flower, the increase production of the celery is 95%, others is 12% to 24%.
Description
Technical field
The present invention relates to from the animal material extraction and plant growth regulator, also belong to the technical field of shitosan simultaneously.
Background technology
Shitosan has the insect pest of the plant disease-resistant of raising as plant growth regulator or nutrient solution, and anti-adversity ability promotes growth, increases output, improves the effect of quality, and Nonpoisonous, non-environmental-pollution, is a kind of eco-friendly preparation.If the use low molecular weight water-soluble shitosan has higher physiologically active, favourable plant absorbing utilization, then above-mentioned effect is more remarkable.
In the prior art, existing many patents provide data and the experience that shitosan is used for agriculture aspect, show the growth of shitosan to plant, truly have the effect of multiple beneficial.Particularly be the Agrotechnical formulation of major function composition, more can highlight quick-acting, disease-resistant, degeneration-resistant, the effect that raises productivity and improves the quality of shitosan with the low molecular weight water-soluble shitosan.Open flat 4-253901 as CN1289743, CN1257055, spy.But above-mentioned patent has only provided the fitting method that described preparation is formed, and the water-soluble shitosan of used low-molecular-weight need be produced or outsourcing separately, increases operation burden and production cost, and application will be restricted.In addition, its effect of increasing production also can not be satisfactory.
Summary of the invention
At the deficiency that prior art exists, the present invention aims to provide that a kind of manufacture method is simple, with low cost, obvious effect of increasing production be the plant growth regulator of main component with the low molecular weight water-soluble shitosan.
Product of the present invention contains following composition and ratio (w%):
Chitosan oligomer 0.50～10.00%
Solubilizer 0.01～1.00%
Synergist 1.00～10.00%
Sylvite 1.00～10.00%
Water surplus
Described chitosan oligomer is the low molecular weight water-soluble shitosan of molecular weight＜10000; The surfactant of the alkylphenol polyoxyethylene class that described solubilizer is can be used as OP class and NP series products, with OP-10, OP-15, NP-10 for well; Described synergist is urea or urea phosphate; Described sylvite is sulphate, nitrate, chloride or the carbonate etc. of potassium.
Low molecular weight water-soluble shitosan is that (molecular weight is 50000～500000 with the higher molecular weight shitosan, deacetylation 70～95%) makes by oxidative degradation with degradation agent, the water soluble chitosan mother liquor is purified without separating, directly add other auxiliary agents and allocate, make the plant growth regulator that contains water soluble chitosan.
The used oxidative degradation agent of oxidative degradation can be NaNO
2, H
2O
2, NaClO etc., wherein with NaNO
2Better, advantage is that consumption is few, and the water soluble chitosan yield of generation is higher, the reaction condition gentleness, and the remaining nitrite in reaction back is eliminated easily fully.H
2O
2Can under neutrality, carry out NaClO and NaNO
2Must under acid condition, react.
NaNO
2, the consumption of NaClO and the mol ratio of high molecular weight chitosan be 0.02～0.50: 1.00, reaction needs carry out under the acid condition of PH＜5, the addition of acid or glacial acetic acid will surpass the amino and the NaNO of high molecular weight chitosan slightly
2Or 1.05～1.25 times of the summation of both moles of NaClO.Reaction can be dissolved with shitosan fully 20～50 ℃ of reactions, and does not have precipitation and separate out and be terminal point in alkaline solution.
Described H
2O
2When practical application, be to use the technical grade hydrogen peroxide, contain H
2O
227.5%.Can under neutrallty condition, react when carrying out oxidative degradation, also just need not to add acid or glacial acetic acid with hydrogen peroxide.Be reflected under 60～90 ℃ and carry out, till shitosan dissolves fully.
Add solubilizer, synergist, sylvite and excess water after reaction is finished in container, under room temperature, mix, dissolve, be mixed with the plant growth regulator that contains water soluble chitosan.Preparation finishes and can filter or not filter, to be filtered into.
Solubilizer is that alkylphenol polyoxyethylene class surfactant adds the solvability that helps increasing each component, promotes the plant absorbing utilization, and can strengthen the ability of antibacterial bacteriostatic.The effect that synergist and sylvite add is except the fertilizer efficiency because of interpolation N, P, K raising preparation, and wherein urea phosphate and urea also have the effect of eliminating micro-nitrite remaining in the preparation fully.The addition of synergist and sylvite can make the content of N, P in the product, K in 1.00～10.00% scopes.
The water soluble chitosan plant growth regulator that contains of the present invention can activate plant cell, promotes growth, strengthens resistance, suppresses damage by disease and insect, improves fruit quality, and is nontoxic.At booth, greenhouse, open country, vegetables such as celery, tomato, cucumber and strawberry are carried out application test through the professional of agriculture of ground agricultural stations such as the Liao Dynasty, Ji, Shandong, Shanghai, its rate of growth is 12～24% except that celery, and particularly the rate of growth of celery reaches 95%.Effect of increasing production to these crops is very significant.
Compared with prior art, the invention has the advantages that not only provides a kind of new aqueous soluble chitosan plant growth regulator and compound method thereof, and provides by polymer chitosan, produces the method for water-soluble chitosan oligomer by oxidative degradation.This method is simple to operate, the reaction condition gentleness, and the degradation reaction product need not separate purification, can directly be deployed into plant growth regulator.In addition, it can make some crops increase production significantly.
