Abstract
The present invention relates to plant growth regulator. The plant growth regulator is a water solution by using one or multiple compounds of soluble chitin, carboxymethyl chitin and carboxymethyl chitose as effective components, or is a water solution containing 0.015 to 1.5% of diluted acid. The preparation process of the plant growth regulator is simple, and the plant growth regulator can be applied to the process of crop cultivation by adopting various methods; the plant growth regulator has the advantages of multiple varieties of applicable crops, simple and convenient application method, and obvious effect on crop yield.
Description
The invention provides and a kind ofly can promote crop growth, improve the plant growth regulator of crop yield and the application of this conditioning agent.
In agricultural production, for improving the output of crops such as wheat class, paddy rice, vegetables, sugarcane, genseng etc., the existing technology of using plant growth regulator that adopts.Close with technology of the present invention, adopt soluble chitin and rare organic acid or inorganic acid reaction to form chitin salt as Japan Patent (special 63-297305), be neutralized to the neutral conditioning agent that is made into as the effective ingredient of conditioning agent with alkali then.Used organic acid has formic acid, acetate, glutamic acid, methionine, lactic acid etc., and inorganic acid adopts hydrochloric acid or sulfuric acid.The using method of this conditioning agent is very simple, at first utilize the water-soluble solution that is mixed with 1～10% (weight) of effective ingredient of the above-mentioned conditioning agent that makes, employing is to the method for crop seed soaking or crop foliage-spray, be applied on the crops, can reach the purpose that promotes plant growth, improves crop yield.But the preparation of said method conditioning agent need consume a large amount of alkali, and operating process is complicated.Simultaneously, the range of application of conditioning agent is also more limited, and the amplitude that crop yield improves is little.
The purpose of this invention is to provide a plant growth regulators, this conditioning agent preparation is convenient, can be widely used in crops such as vegetables, fruit, grain and oil, and significant production-increasing function is arranged.
Plant growth regulator provided by the invention is characterized in that adopting containing that one or more compounds are the aqueous solution of active ingredient in soluble chitin, carboxymethyl chitin or the CMC.The preparation of this conditioning agent is very simple, only needs soluble chitin, and the water-soluble aqueous solution of making of carboxymethyl chitin, CMC or their mixture is conditioning agent.
Active ingredient in the above-mentioned conditioning agent also can be earlier 1～10% diluted acid with concentration, for example after organic acid such as formic acid, acetate, lactic acid, citric acid, benzoic acid or naphthenic acid and the mineral acid treatment such as hydrochloric acid, nitric acid or sulfuric acid, adds water again and is mixed with conditioning agent.Also the active ingredient of conditioning agent directly can be added to concentration (weight) and be in 0.005～1.5% the diluted acid and be mixed with the conditioning agent that directly to use.
Plant growth regulator of the present invention can be applicable to grain and oil crops such as wheat class, paddy rice, corn, soybean, rape widely, also applicable to vegetable and fruit class crops such as cherry, peach, sugarcane, strawberry, genseng, Chinese cabbage, tomato, potato, cottons.Using of conditioning agent is very simple, after at first the conditioning agent of above-mentioned preparation being added that water is rare and making the concentration that contains effective composition and be the aqueous solution of 30～8000PPm, can use.The concentration of value is 1500～3000PPm.Use several different methods such as to adopt seed soaking, crop growth period Nei Genshi or blade spraying, all can receive significant effect of increasing production.
Below by example technology of the present invention is further described.
Embodiment 1
Select the soil property fertility basic identical, more smooth location is as the test region.Soluble chitin 3 gram is added in the solution that other organic acids such as the lactic acid of 1000ml0.5% or formic acid are made into, then the potato kind of cutting was immersed above-mentioned test solution bubble respectively 30 minutes, taking out nature dries, at once sowing.After planting do not go and buy Chinese medicine, do not topdress the time of infertility, do not manage.Results are surveyed and are produced at last, and the potato comparison after the seed soaking is according to (using the same amount water treatment, as follows) volume increase 21.3%.If carrying out root under the same conditions executes processing, then comparable contrast volume increase 47.5%.
Embodiment 2
The test region is selected with embodiment 1, adopts 4 gram carboxymethyl chitins to add 1000ml water again with 15 times of its concentration dilutions, is respectively applied for foliar spray (handling I) and root and executes (handling II), and contrast with clear water, gets the mean of 10 strains at random and surveys product.The results are shown in Table 1
Table 1: strawberry result of the test
Embodiment 3
Test and Selection booth tomato carries out.Dilute 10 times again with being mixed with solution in the 3 gram CMCs adding 1000ml water, all fertility sprays twice therebetween, spray when the tomato seedling field planting for the first time, spray for the second time 10 days after the first time, survey at last and produce the result, the chemicals treatment comparison is according to spraying with water gaging volume increase 41.39%.
Embodiment 4
Select experimental field that soil property is a sandy loam, area 20m
2, middle fertility, the preceding crop corn of recommending, the autumn turns over the back rake and presses the guarantor.Next year is ditch sowing corn again, and the corn kind was soaked 16 hours with the medicament of two times of the concentration dilutions of embodiment 3 earlier, dried the back sowing, executes the urea 1.05Kg that topdresses in breeding time again, fertility period three shovel twice, the results back is surveyed and is produced comparison according to volume increase 5.2%.If root is executed under the same conditions, then comparable contrast volume increase 9.3%.
Embodiment 5
Adopt the conditioning agent aqueous solution of embodiment 3 preparations, cherry is sprayed by 4 kilograms/strain, totally 2 times, to survey at random after the maturation and produce, comparison is according to volume increase 18.5%.
Embodiment 6
The test region is selected with embodiment 1, and 1 gram carboxymethyl chitin and 2 gram CMCs are dissolved in the 10Kg water, and root is executed once after the Chinese cabbage field planting, measures comparison at last according to volume increase 20%.
Adopt plant growth regulator provided by the invention as seen from the above-described embodiment, its compound method is easy, can use multiple kinds of crops, and receive significant effect of increasing production.
