Description

Preparation method and application of multifunctional metal salt composite membrane composition

Technical Field

The invention belongs to the field of agricultural plant protection, and particularly relates to a preparation method and application of a multifunctional metal salt composite membrane composition.

Background

The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.

Agriculture is the root of a country and is also the support of farmers, and the fruit tree economy is an important economic source in some places. With the increase of the yield of apples and the increase of labor cost in recent years, the net income of fruit growers is gradually reduced, the production enthusiasm of the fruit growers is reduced, and the development of the whole industry is not facilitated. The main factors are that firstly, the labor amount is large in the apple bagging process, the labor intensity is high, secondly, the pesticide effect in the aspect of fruit tree flower thinning is unstable, the labor intensity of fruit thinning is increased, thirdly, rotten fruits caused by germs and physiological diseases in the storage period of fruits are increased, fourthly, the fruit trees are artificially whitered in winter, the labor amount is increased, and the management enthusiasm of fruit growers is reduced. Fifthly, before picking, the fruits packaged in paper bags need to be picked manually, so that time and labor are wasted, and farmers can feel ugly.

In addition, the problem of pesticide utilization rate generally exists at present. The use amount of chemical fertilizers and pesticides is advocated to be reduced in the industry all the time, green development of agriculture is required, and the quality of agriculture is realized. However, the land management method mainly manages the land management in a distributed manner. The situation that the pesticide is used randomly and the dosage is increased and the situation that the pesticide is sprayed in large fog drops and large volume still cannot be fundamentally changed when the pesticide is used.

According to scientific measurement and calculation, the utilization rate of the pesticide in 2017 is 38.8%, which is improved by 2.2% only compared with that in 2015. Rice in 2019. The pesticide utilization rate of the corn and wheat grains is improved by 1 percent compared with that of the corn and wheat grains in 2017. Although some results have been achieved, it is difficult to make substantial progress in reducing the amount of pesticide used without improving the innovative mechanism.

Large spray head and high power. Finally resulting in the embarrassment of dripping the front and the back. After the common sight is used for a long time, farmers also naturally accept the way. According to statistics of relevant personnel, the pesticide deposited on the plants after spraying only accounts for about 35% of the total spraying amount, and the pesticide drifts into the air along with the air flow and accounts for about 20%, and the pesticide deposited on the plants rolls down to the ground because of the accumulation of fog drops and accounts for about 40%. The proportion of the evaporated air is 5%. This is an extremely important ring which causes waste of the pesticide. In addition, pesticide lost in the soil pollutes the soil and the water environment, so that the health of human beings is threatened, and the problem is urgent.

Research discloses a spray film-forming type fruit and vegetable or crop bagging composite material and preparation and application thereof. Southern China university of agriculture, jiang Gangbiao, liu Yonglin. The defects that the diatomite, the graphene, the clay, the mica, the kaolin and other insoluble solid powder are contained, the membrane has poor air permeability, so that a large amount of spraying can not be carried out, the photosynthesis of plants can be influenced, the transpiration is limited, the yield of the plants is reduced, and the fruit quality is poor. When used in a small amount, the plant protection agent can not generate the effect of fully protecting plants. Such products achieve the aim of complete protection of the plant by physical isolation, are difficult to implement and are at the expense of yield and fruit quality.

A higher fatty alcohol ester membrane, its preparing process and its application are disclosed. The implementation of this file is also for physical protection purposes. The price of the product is high, although the concentration multiple of the spraying proportion is as high as 300 times. However, the quality of the protective film after the medicine film is formed is too thin, so that the protective film is not easy to avoid the infection of germs. Such physical isolation is also a difficult goal to achieve.

In recent years, in the popularization process of the technology, organic calcium is added to prevent fruit cracking and physiological diseases, bacillus is added to weaken pathogenic flora by using competition among flora, and foliar fertilizer is added to supplement nutrition of plants and increase disease resistance of the plants. However, competition among populations still exists, harmful bacteria still exist, serious rotten fruits still occur once the infection chance is mature, the disadvantage is that 1, the drug effect is unstable, 2, after rain, humid conditions make the competition between populations for growth and reproduction more violent, and for the sake of insurance, timely reissue is needed, and 3, because of the existence of bacillus biological bacteria, extreme weather cannot be used.

Research has disclosed preparation and application of a pesticide spray adjuvant composition, the spray adjuvant is mainly made up of natural edible gum (including its raw materials), have green, environment-friendly, safe and harmless characteristic. The auxiliary agent is suitable for various formulations of pesticides, has the effects of enhancing the adhesion and wettability of liquid medicine, increasing the spreading area of the pesticide, delaying the spray evaporation speed, reducing the fog drop drift, improving the control effect of the pesticide and reducing the application cost of the pesticide. The adjuvant has wide application range, and can be used in combination with various pesticide components such as herbicide, pesticide, bactericide, plant growth regulator, etc. But the inventor researches and discovers that: the components of the bactericide in the method are simply mixed, the composition can be wetted and expanded when meeting water after being sprayed into a film, the film body is easy to damage under the scouring of heavy rain, even if solid pesticides such as wettable powder and the like are added, the space for expanding the film after meeting water is large due to large solid particles and large gaps among the solid particles, so that the toughness of the film is reduced, and the sterilizing effect after heavy rain still needs to be improved.

The metal salt, boron salt, silicon salt, etc. can prolong storage period and prevent physiological rotten fruit. The copper salt, zinc salt and silver salt can kill germs.

At present, copper preparations are divided into organic copper and inorganic copper, and are mostly prepared into liquid by spraying organic copper preparations, such as oxine-copper, copper ammine complex and nonylon copper. The copper content in the components is very low, and the long-term sterilization purpose cannot be met at all. The inorganic copper is larger than the organic copper in use, but has the problem of safety, plant poisoning can be caused by excessive use, and the lasting period is only about 10 days. Bordeaux mixture, although lasting up to half a month, is poorly compounded due to its alkaline nature.

In a third aspect of the present invention, there is provided a method of using a plant fungicide protective film composition comprising: a, spraying any one of the plant bactericide protective film compositions on crops to obtain the plant bactericide protective film composition. b, preparing the protective film into paste to be applied to the branches and prevent and treat the rot disease of the fruit trees. c, spraying the protective film composition on branches and trunks of fruit trees in winter and spring to kill harmful bacteria in winter.

The invention has the beneficial effects that:

(1) The present invention relates to a medicine liquor made up by using copper sulfate or zinc sulfate and other salts, sodium salt or potassium salt and calcium salt, polyvinyl alcohol or edible gum or thickening agent and water, and is a uniform viscous liquid. And the liquid medicine has high viscosity, can be well and tightly attached to the surface of a plant body, and can be immediately adhered to the surface of the plant body where the liquid medicine is sprayed, so that the liquid medicine cannot flow and rarely rolls off. Greatly improves the utilization rate of the pesticide.

(2) When the liquid medicine is prepared, the metal salt does not aggregate into floccule but is suspended in the liquid medicine because of the existence of sodium salt, potassium salt and thickening agent. The bactericide is sprayed on crops, the advantages of bactericides such as copper ions in the components are shown, and the bactericide is characterized in that a, organic copper precipitates in liquid medicine are fine in particles in the liquid before the liquid medicine is dried, so that the organic copper precipitates are larger in area contacting with water molecules and are dissolved in water, the copper ions can be immediately sterilized after being released, after a medicine film is dried, the bactericide is attached to plant bodies to play a role in protection, and other copper preparations only play a role. b, long lasting period, especially outstanding water resistance, and c, easy mixing with other bactericide. The three are innovation points of the invention, and in the current technology, the copper preparation is divided into organic copper and inorganic copper, and most of the organic copper preparation sprayed on the copper preparation is prepared into liquid copper, such as oxine-copper, copper ammine complex and nonylon copper. The copper content in the components is very low, and the long-term sterilization purpose cannot be met at all. The inorganic copper is larger than the organic copper in use, but has the problem of safety, the plant poisoning is caused by excessive use, and the lasting period is only about 10 days. The Bordeaux mixture with the lasting period of about 15 days also has the safety problem, and the alkaline property limits the mixing of Bordeaux mixture with other pesticides, increases the pesticide spraying times and increases the burden of farmers. The organic copper is a water-insoluble sterilization protective agent, has the advantages of the organic copper and the inorganic copper, has large dosage and long lasting period, and has longer lasting period in 6, 7 and 8 months compared with Bordeaux mixture in high-temperature rainy seasons. Meanwhile, the safety is high. After the composite film is combined with sodium salt, potassium salt and adhesive to form a film, the medicinal film expands when meeting rainwater, and the fine organic metal particle salt can limit the expansion of the medicinal film, so that the strength and toughness of the medicinal film are enhanced under the action of double forces, and the rainwater scouring resistance of the medicinal film is greatly enhanced. The formed protective film also has a slow release effect.

(3) The protective film formed on the surface of the plant by the Bordeaux mixture is often influenced by the natural environment and the factors of the Bordeaux mixture. Carbon dioxide and water vapor in the air can enable the Bordeaux mixture to slowly release copper ions, and meanwhile, the carbon dioxide and the water vapor can be utilized by plants under the photosynthesis and the transpiration to decompose the Bordeaux mixture medicine film at the place tightly contacted with the leaves. So that it is easy to fall off and fail in the weather. The invention overcomes the defects and greatly prolongs the effective period.

(4) The invention can also be added with other bactericides such as chlorobromoisocyanuric acid and the like, and can achieve the purposes of rapid and thorough sterilization and perfect protection. Also, the organic metal film of the present invention has a difference in the effective period of the surface thereof due to leaves and fruits of plants, one is a nutritive organ and the other is a reproductive organ. When the bactericide such as chlorobromoisocyanuric acid is separately sprayed, the liquid medicine can be adhered to the surface of the medicine film, so that the deposition amount of the pesticide is increased, and the simulation is enhanced.

(5) The protective film of the invention is mostly a biological protective film, the protective film is not easy to be eaten by external microorganisms under the protection of an organic metal film, and when bactericides such as chlorobromoisocyanuric acid and the like are independently sprayed, the liquid medicine can be adhered to the surface of the liquid medicine film, thereby improving the deposition amount of pesticide and enhancing the simulation.

(6) The invention belongs to chemical protection, and the rotten fruit rate of fruits is fundamentally solved in the storage period after the fruits are picked. For example, in the storage period of apples with plastic film bags, water vapor is generated and exists in the film bags due to the physiological action of the film bags, and then small-particle fine water drops are formed and are utilized by disease bacteria to germinate and grow to infect the whole fruits. The invention has a layer of protection of the drug film, so that the germs can not be released from the hands.

(7) The invention can be sprayed in the young fruit period of the plant, thereby reducing fruit rust and keeping fruit surface smooth. So that the product has good marketability.

(8) When the protective film is used, the protective film can block the air valves of pests, plays a role in killing aphides and red spiders, and is one of the innovation points of the invention.

(9) The invention can also play and strengthen the effect of flower thinning. This is also the innovative point of the present invention,

(10) The invention solves the problem of bagging puzzling fruit growers for a long time. This is the innovative point of the present invention.

(11) The invention can simultaneously supplement various nutrients such as copper, iron, calcium, magnesium, boron, silicon and the like, help to delay the aging of fruits and prolong the storage period of the fruits.

(12) The invention can replace manual whitewashing of orchards, reduces the labor amount and improves the enthusiasm of fruit growers. This is the innovative point of the present invention.

(13) The invention can supplement calcium and boron at the same time, and solves the problem of antagonism of two nutrient elements. This is also the innovation of the present invention.

Also, there are often even thickeners named, which differ in the amount used because of the type. Since there are cases where a plurality of objects are used in common, the above embodiment is described only in part, not in whole.

In the following examples, the application times (dilution times) of the chemical mixture solutions were the same (cucumber, grape, spraying amount 30 jin, area half mu of land).

Experimental example 1

The advantages of the present invention will be specifically shown by the effects of the present invention.

Cucumber downy mildew, a subject of implementation, greenhouse facility cucumber.

Description of the drawings: "20% difenoconazole +25% pyraclostrobin +86.2% cuprous oxide" means: and respectively and sequentially adding 20% of difenoconazole, 25% of pyraclostrobin and 86.2% of cuprous oxide into a small amount of water, mixing, diluting for the second time, and using, wherein the meaning of the combination of other pesticides is similar to that of the combination of other pesticides.

In this embodiment, difenoconazole, pyraclostrobin, cuprous oxide and the usage times (dilution times) of the pesticide mixed liquid are the same (spraying amount is 30 jin, and the area is half mu of land).

The experimental conclusion shows that the drug duration of the invention is obviously longer than that of the conventional pesticide after the results of the example are compared. The comparative examples, in spite of the addition of the inorganic copper preparation, show that the duration of the organic copper is inferior to that of the invention. And the difference of control effect will be gradually expanded with the lapse of time.

Experimental example 2

Preventing and treating powdery mildew of cucumber. The implementation object is greenhouse facility cucumbers.

The experimental data show that the protective film can play a role in slow release of the pesticide. It is shown that the metal salt component of the composition has better bactericidal effect and lasting period if the zinc salt is replaced by copper salt.

Experimental example 3

Grape downy mildew. Implementation object, greenhouse facility grapes.

The data show that the bactericide protective film can still maintain high control effect under the condition of reducing the pesticide spraying times. The invention plays a positive and effective role in reducing the pesticide spraying times and the burden of farmers.

Experimental example 4

Preventing and treating effect of cercospora brown spot of apple trees. Four red Fuji apple trees with the same size and scale are divided into two groups, and each group comprises two trees. Before the experiment, the fruit trees are normal. No obvious diseases

The embodiments show that the invention has the advantages of low dosage, high control effect and long drug effect duration, and can radically solve the dosage of the pesticides for fruits and vegetables on the basis of dosage times (generally, one time of pesticide application in 10-15 days). Plays a positive role in improving the enthusiasm of farmers for planting.

Experimental example 5

Cucumber angular leaf spot, implementation object, greenhouse facility cucumber.

As can be seen from the above examples, even if the bactericide is replaced alternately and the pesticide application times are increased in the conventional disease control aspect, the lasting period and the control effect of the pesticide are not as good as those of the invention.

Experimental example 6

The invention has the effect of thinning the axillary flowers of the apple trees. 4-8 full-bloom stage, spraying time is 4-11 months, and 10 am. The effect% = (number of small fruit drops + number of handle yellowing) is divided by the total number of handle of the axillary flower which is opening for one fourteen-year-old yellow golden handsome apple tree. ( Note that the inflorescence is sprayed intensively, and the spraying amount of each time is about 1.5 times of that of the conventional spraying amount. The normal amount is 10 jin. )

The experimental data show that the invention has the effect of thinning flowers of axillary flowers of apple trees, and the effect is improved along with the increase of the administration times. As the Jinshuai apples are self-pollinated, the pollination rate and the fruit setting rate are extremely high. The experimental data can confirm that the invention has the flower thinning effect. It is noted that the bactericide in the composition does not act as a thinning agent.

Experimental example 7: test item, fruit bag

The experimental subject, golden commander apple tree of forty-three years old, had no control in this experiment, but could be clearly understood from the experimental results. The test procedure was as follows:

the first insecticide is applied at No. 8/7/2021, the preparation adopts the example 11,

no. 8/1, the second time of the insecticide application, the agent adopted in example 14,

no. 8/14, third-time insecticide application, the preparation adopts example 11,

spraying the pesticide for three times by using a spraying machine, wherein the number 9 month 5 is the fruit harvesting period, 100 small apples are remained after the number 9 month 5 harvesting period and are continuously observed to be number 9 month 20, and three times of heavy rainfall is experienced in the period.

Experimental results, only 3 rotten fruits were found from the first insecticide application to 9 months 5, and the reasons were carefully analyzed, wherein one of the reasons is that the fruit branch is located at the tip of the tree, the fruit grower does not loose fruits, and three apples are crowded together, so that one of the three apples is not evenly applied with the insecticide. The other two diseases have the same disease occurrence condition, the skin has concave downward collaterals as a disease occurrence result, and the primary judgment shows that the tiny cracks caused by the calcium deficiency of the fruits infect the germs, but the germs can not be identified by naked eyes. After the diseased fruit was sliced, the microscopic cracks were observed under an optical microscope, and the fine cracks were observed, as shown in fig. 8 and 9. Another 100 small apples were observed continuously, to No. 9/20, of which 16 were ripe and dropped. In all the inspection results, no rotten fruit was found. The efficacy of 100 smaller apples was maintained for 37 days and still showed no evidence of rotten fruits. Therefore, the experimental conclusion is drawn that the technology of the invention is feasible and reliable.

FIG. 3 is a graph of apple using the drug solution application test of example 14, and it can be seen from FIG. 3 that the apple ring spot was so crowded that the uncovered part of the drug was diseased. This is the only one in the trial that resulted in rotting due to the failure to deliver the drug.

Fig. 4 is a graph showing the effect of the leaves of example 14 after being sprayed with the agent, which is thick enough to make ants gather only at the edges of the leaves.

FIG. 8 shows the observation picture of the apple without bag under microscope, the thickness of the slice is 3 mm, and the center of the observed object can be seen to have scab when observed under the illumination of the flashlight.

FIG. 5 is a view showing the coating on the fruit surface after the chemical of example 14 was sprayed thereon, and the coating was uniformly observed under a high power microscope.

Experimental example 8 Effect of the composition on fruit thinning.

Time 2022, 4 months, 4 # evening, 6 o' clock. Tree species, street greening trees, flowering crabapple flowers. The daytime temperature is 12-22 ℃. The first experiment shows that the product comprises 27 g of potassium sorbate, 10 g of anhydrous calcium chloride, 15 g of xanthan gum, 20 g of calcium formate and 2000 g of water. Experiment two, the product contains 20 g of calcium formate and 2000 g of water. Both use small hand-held applicators. Experimental results, there are photographs to compare the results. Fig. 10 corresponds to experiment one, and fig. 11 corresponds to experiment two.

As a result, both the first experiment and the second experiment have the flower thinning effect, but the flower thinning effect of the first experiment is larger than that of the second experiment. Note that this experiment is only a qualitative experiment of thinning. No. 4, 8, 9, 10 and 11, the temperature is about 30 ℃ at the highest in the flowering period of the apple, so that the interval time between the central flower and the side flower of the apple is slightly short, and the quantitative test of thinning flower cannot be carried out.

Experimental example 9 the effect of the composition on apple tree aphids and red spider mites.

No. 18 in 6 months, golden commai apple trees, which contain 300 g of potassium sorbate, 250 g of blue copperas, 150 g of guar gum and 100 kg of water. A spray coater is used. At 9 am, the test tree is sprayed with the pesticide, tender tips with aphids are taken home and inserted into a paper cup filled with water for convenient observation, and the observation shows that a part of aphids obviously fall into the water at 7 am in the next day. This effect is caused by blocking the stomata of the pests.

The observation of the effect of the red spiders shows that the red spiders lose the activity immediately after being covered by the liquid medicine, and die quickly after the liquid medicine is dried into a film in about ten minutes, which is the creativity of the industry. Experiments also prove that the formula has good control effect on the small winged insects on vegetables such as tomatoes, eggplants and the like. FIG. 12, aphid status immediately after application, aphid results observed the second day in FIG. 13, and FIG. 14, aphid death and landing on the table, observed at 7 am after the drug application.
