Description

Cold-season type lawn growth regulator and preparation thereof

Technical field

The present invention relates to a kind of combined chemical regulation product of using in cold-season turfgrass adjusting and controlling growth field.

Background technology

The present invention relates to component, content and the preparation method of a kind of resource-conserving chemical control product-cold-season turfgrass growth regulator.Product is mainly by applying dioxan aminoethyl alcohol carboxylic ether (code name DA-6, commodity are richly by name), uniconazole P (formal name used at school UniconaiolePentefeizol Sumiseven code name S ₃₃₀₇), ferment bacterial manure, biological bactericide and insecticides adjuvant mixed preparing form.Be divided into two kinds of preparations: I. lawn growth promoter, II. lawn growth delayer.Be applied to respectively the lawn turn green preceding, the growth mid-term and the growth latter stage.

Applying dioxan aminoethyl alcohol carboxylic ether is by Xiamen University and the common a kind of new plant growth regulator developed of Xiamen De Feng Fine Chemical Works.The effect that plant growing is had adjusting, promotion.This product is white-buff powder, and is soluble in water, and acid, heat, light are stablized.According to the toxicity of pesticide classification, this medicine is nontoxic substantially sexual type.By improving the content of plant inner chlorophyll, protein and nucleic acid; Improve photosynthetic rate, improve peroxidase and vitality of nitrate reductase; Improve the absorption of plant carbon, nitrogen metabolism, enhancing plant to liquid manure.Regulate the balance of moisture in the plant body, thereby improve drought resisting, the cold resistance of plant, and have the effect that delays plant senesecence." get rich " at present and be widely used in crops, in the production of vegetables and flowers.

Uniconazole P is SUMITOMO CHEMICAL chemical company early eighties is released in last century a kind of efficient plant growth delayer and a wide spectrum internal-suction type bactericide, is mainly used in the dwarfing and disease control of plants such as crops, fruit tree and flowers.Uniconazole P belongs to low-toxin farm chemicals, and the field is used and is easy to decompose, and is seldom residual in soil.This medicine has multiple physiological effect to plant, and activity is very high.1, downgrading long dwarfing of effect control is the remarkable and the most effective biological effect of uniconazole P, has broad spectrum activity and high efficiency characteristics.Application at present is comparatively extensive, as cereal crops paddy rice, barley, wheat, and oil crop rape, soybean, economic crops crudefiber crop, cotton, fruit tree, vegetables, flowers etc.; 2, short root, short tiller, short branch effect.Because uniconazole P has suppressed the elongation growth (inhibition plant height) of plant, so the nutrient transport in the plant corpus is assigned formation and the growth that is beneficial to short root, short tiller and short branch.Therefore fast, the new root growth of root growth is many, and merogenesis, branch are also many and the tiller position is low.3, increase chlorophyll content, increase photosynthesis, delay senility.Chlorophyll content in leaf blades after handling after measured increases.Protein content increases, and therefore handling rear blade leaf look dark green.Chlorophyll content increases, and photosynthesis of plants just strengthens.The anti-adversity ability of crop is generally all represented with photosynthetic power.Show that according to data the photosynthesis of plants that can alleviate after the processing under Lao Ye and the stress conditions such as low temperature and arid descends.

Ferment bacterial manure ferment bacterium fertilizer is the biological organic fertilizer that is rich in active bacterium and secretion fermentation product thereof of the Korea S's exploitation seventies in last century.This bacterial manure tool fixed nitrogen, the insoluble organic phosphor of decomposition and inorganic phosphorous compound decompose multi-efficiencies such as sylvite, have the effect that suppresses disease fungus simultaneously.The biological bactericide that the present invention selects for use is the disease fungus inhibitor with inducing plant resistance, and through strict antagonistic experiment and compatibility experiment, discovery does not cause negative effect to the active flora kind and the quantity of ferment bacterial manure

The biological bactericide bactericide can be divided into protective fungicide and curative fungicide agent, and the two has his own strong points.Jinggangmeisu and polyoxin have preventive effect to the various plants disease fungus according to the literature, promptly plant are had the effect of induction of resistance, have the feature of protective fungicide.It is component that the present invention selects the firm mycin of well of Zhejiang Qian Jiang biochemical corp production and the polyoxin of Yan Bian spring thunder drugmaker production for use, also can select the product of other manufacturer production for use.

Insecticides adjuvant is generally the complex function product at present, has multi-efficiencies such as surfactant, dispersant, spreader-sticker, stabilizing agent and anti ultraviolet agent concurrently, is uniquely among the present invention not have a biologically active, but is important to be the component of one with each component is molten.Present domestic many enterprises produce.The present invention selects the product of Liaoning Province a company for use.

It is also few that at present plant growth regulator is applied to the kind on lawn, and main cause is that also plant growth regulator all designs production at crops, fruit tree and vegetables, and the research that is applied to the prescription on lawn and using method also seldom.It is reported that Wang Manlin (Academy of Agricultural Sciences Institute of Plant Protection, Beijing) and Liu Jiafen (Shandong Fruit-tree Inst.) once were applied to turfgrass with uniconazole P, but yet there are no the report that " getting rich " is applied to the lawn.The main effect of uniconazole P is to delay plant senescence, and the present invention combines uniconazole P with the other biological active substance, overcome the limitation of single agents.

Summary of the invention

Innovation part of the present invention is " to get rich plant growth regulating substance " first, and combining with plant growth retardent is applied in the maintenance management of turfgrass, and be equipped with other bioactivator, through scientific matching, both combine the advantage of each component, can overcome each prescription deficiency of using and the problem that produces poisoning again.

Through the application on turfgrass (annual bluegrass and perennial ryegrass etc.) and the different growing stage lawn from different places in Dalian, this adjusting control agent to the turfgrass different times grow, physiologically active and resistance regulation index all have appreciable impact.Warp is to 46 mensuration projects, the calculating of more than 6000 test data and analysis, the result shows: compared with the control, in good time spraying preparation I. lawn growth promoter, plant is turned green ahead of time, promote that turfgrass grows, many physiological and biochemical indexs increase, comparison is shone and is improved 56% as chlorophyll content in leaf blades, respiratory rate improves 20.9%, protein and nucleic acid total amount are compared respectively according to improving 30.54% and 2.65% in the blade, the recruitment of peroxidase and nitrate reductase reaches significance level compared with the control in the plant, improves 10.65% and 45.43% respectively, thereby has promoted the growth of turfgrass.The growth rate of using lawn growth promoter is 2.46 times of control group, and the leaf width increment of processed group is 1.5 times of processed group.Total absorption area and enliven absorption area and improve 51.61% and 72.73% than control group.The root system vigor improves 28.81% than control group, has improved the ornamental value of turfgrass greatly.

Compared with the control, in good time spraying preparation II. lawn growth delayer, the vigorous growth of controlled turfgrass in vegetative period reduces the consumption of nutrient and moisture.Studies show that, use the content that the lawn growth delayer can reduce endogenous hormones IAA, improve leaf chlorophyll a, b, T and soluble sugar, protein, DNA, RNA total amount; Improve turfgrass peroxidase, nitrate reductase activity, strengthen root activity; Increase the turfgrass root/shoot ratio, make plant obviously downgrade, tiller increase, the number of blade increases, blade thickness, demonstrates short, thick, strong, thick and close view.The resistance index determining shows: plant after treatment is under water stress, and natural moisture content is higher than contrast.Free proline content reduces, and the cell plasma volumes of extravasation result reduces under the low temperature stress, thereby has improved drought resistance and the cold resistance of plant.

Use the plant height comparison of lawn growth delayer to shine reduction about 20%, the wide increase about 10% of leaf, tiller number increases more than 20%, and careless look darker.The IAA comparison has illustrated the internal cause that suppresses growth according to low 16%-32% in the physical signs.

The growing ability and the physiologically active on the raising explanation lawn of these indexs are stronger, and have more sight.The recruitment of peroxidase and nitrate reductase reaches significance level compared with the control.The former effect is to remove H ₂O ₂With other peroxide.Studies show that in a large number POD is as the protective enzyme in a kind of plant cell, not only to resist unsuitable environmental condition such as low temperature etc. relevant with plant, and resist in various diseases and the environment with plant that some nutritive element is coerced and plants antisenescence is relevant.The latter is the key enzyme of plant nitrogen metabolism.Nitrate is the main nitrogen of most of plants.Nitrate anion changes nitrogen earlier into through the nitrate reductase process, and the carburet materialization is closed and formed again, constitutes the various nitrogen components of plant corpus.Nitrate reductase is the initial enzyme of this process, also is rate-limiting enzyme, is in key position in nitrogen metabolism.It is to growth and development of plants, and output is formed with material impact, can be used as the biochemical indicator of plant breeding and nutrient diagnosis.These two kinds of enzyme levels significantly improve ability, the growing ability that has strengthened plant Intolerance environment, increased the organic matter synthetic amount, and can prolong the green phase of lawn growth, improve the sight on lawn.

Use this product, lawn perennate for a long time in, only prune 3-5 time, reduce and prune frequency 70%-80%, the water saving index can reach 40%, and slows down soil nutrient consumption, alleviates hand labor intensity, thereby realizes saving lawn maintenance management cost 30%-50%.The turfgrass cold resistance strengthens, and can be that the lawn prolonged the green phase more than one month, has increased effectively and has viewed and admired the time.This product and technical costs be 0.7-.0.9 unit/m only ²,, can save about 4 yuan for every square metre if with 8 yuan of calculating of every square metre of lawn year maintenance cost.After product was used in addition, turfgrass is good viewed and admired feature, can improve city taste and improve environmental quality, and its social benefit and environmental benefit are more remarkable.

At present, each urban green space area of China constantly increases, and generally all there are millions of square metres of lawns big and medium-sized cities, and more than 600 the prefecture-level city's lawn area in the whole nation reaches tens00000000 square metres.The production of this product, application and popularization will bring great economic benefit for enterprise; Can save simultaneously the usage amount of a large amount of irrigation water, minimizing chemical fertilizer, agricultural chemicals, also have great role for the protection environment.
