Description

Insecticide-fertilizer capable of killing insects at intervals and application thereof

Technical Field

The invention belongs to the technical field of pesticide-fertilizer integration, and particularly relates to a pesticide-fertilizer capable of killing pests at intervals and application thereof.

Background

The integration of pesticide and fertilizer is the hot field of fertilizer research at present, and the integration of pesticide and fertilizer has the functions of balanced fertilization, comprehensive nutrition, broad spectrum, high efficiency, promotion after front control, stress resistance enhancement, fertilizer and pesticide combination and mutual promotion and synergism; meanwhile, the method has the advantages of time and labor saving, safety, simplicity, convenience in storage and transportation, low carbon, energy saving and the like. Especially for crops needing multiple topdressing and multiple application, the research on integration of pesticide and fertilizer is more important.

The prior art discloses a multifunctional bio-organic fertilizer and a preparation method thereof, for example, chinese patent application with the patent application number of CN202011485432.8, wherein the multifunctional bio-organic fertilizer comprises 1000 parts by weight of fertilizer, 2-3 parts by weight of soil remediation agent and 1-2 parts by weight of pyrethrin powder; wherein the fertilizer comprises 20 to 80 weight parts of fertilizer type organic matter, 5 to 30 weight parts of inorganic mineral powder, 4 to 10 weight parts of sulfuric acid, 1 to 2 weight parts of ferrous sulfate, 1 to 2 weight parts of souring and ripening powder, 1 to 2 weight parts of deodorant and 5 to 25 weight parts of biological bacteria liquid; the fertilizer type organic matter comprises at least one of crop waste, livestock and poultry manure, industrial fermentation waste, grass peat, phosphorus bone meal and bone meal; the inorganic ore powder comprises at least one of phosphorus oxide, potassium oxide, manganese sulfate, magnesium sulfate, zinc sulfate, copper sulfate, ferrous sulfate, boric acid and ammonium molybdate; the biological bacteria in the biological bacteria liquid comprise at least one of rhizobium japonicum, rhizobium cowpea, azotobacter and silicate bacteria; the soil repairing agent comprises 90-140 parts by weight of emodin-rich plants, 35-90 parts by weight of erythrina bark, 30-140 parts by weight of hibiscus and 20-70 parts by weight of tannin source natural plants. The multifunctional bio-organic fertilizer can degrade pesticide residues in soil, further improve soil organic matters and improve the nutrient utilization rate of the soil fertilizer. However, in order to better kill insects in the growing process of crops, insecticides with stronger drug property are generally needed to be used and are used at intervals; the multifunctional biological organic fertilizer contains beneficial live bacteria, so that a high-efficiency pesticide is difficult to add; meanwhile, the multifunctional biological organic fertilizer containing the live bacteria has higher requirement on the storage condition because the insecticide is used again at intervals of 10-15 days.

Therefore, a pesticide fertilizer with strong insecticidal effect and without artificial secondary insecticidal is needed at present. And the prior art is as follows: the Chinese patent application of CN202010218772.8 discloses a pesticide bacterial fertilizer for preventing and treating sugarcane diseases and insect pests and a preparation method thereof, the pesticide bacterial fertilizer takes a compound fertilizer as an inner core, and pesticide, microorganism bacteria and the compound fertilizer are sequentially and slowly released through three-layer coating granulation, so that the problems are still not solved.

Disclosure of Invention

The invention aims to provide the insecticide-fertilizer capable of killing insects at intervals, the insecticide-fertilizer blocks can kill insects at intervals, two-time interval insecticidal can be achieved by one-time fertilization, manual secondary insecticidal is not needed, the storage requirement is low, and the insecticide-fertilizer is suitable for large-scale application.

Another object of the present invention is to provide an application of a pesticide fertilizer capable of killing insects at intervals, which can be directly fixed to the roots of crops or directly fixed to the stems of crops, compared to the existing pesticide fertilizer particle structure which is easy to roll off the roots of crops after being fertilized, so as to achieve better effects of killing insects and applying fertilizer.

In order to achieve the above purpose, the technical solution of the present application is as follows:

the insecticide-fertilizer capable of killing insects at intervals comprises at least one block-shaped fertilizer unit, wherein the block-shaped fertilizer unit comprises an insecticide cake and a top dressing cake, the insecticide cake and the top dressing cake are arranged in a stacked mode in the vertical direction and fixed through pressing and/or degradable materials, and adjacent block-shaped fertilizer units are fixed through pressing and/or degradable materials.

When crops grow, after the base fertilizer is applied, top dressing needs to be carried out for 2-3 times, wherein the top dressing generally comprises the step of fertilizing at the roots of the crops so as to provide nutrient substances for the crops and further promote the growth of the crops; the pest control of crops is generally to perform pest killing operation on roots and stems of crops when pests are not adult, especially on fruit trees. Taking grape vines as an example, grapes are generally fertilized for 3 to 4 times in one year, quick-acting fertilizers are mainly used, and the grape vines are mostly fertilized after fruit setting, so that the growth of fruits is promoted, the coloring is promoted, and the fruit quality is improved. The main pests of the grapevine are scarab beetle, scale insect, grapevine tiger beetle and the like, the main damage parts of larvae or nymphs of the pests are root parts of the grapevine, and the pests can prevent the grapevine from normally sprouting, weaken the tree vigor and hinder the flowering and fruiting. However, whether top dressing or killing insects, in order to provide sufficient absorption time for fruit trees, 10-15 days are generally required to be separated. Because the pesticide application part and the fertilizing part of the top dressing are overlapped and have intervals, the problems of multiple top dressing and multiple killing can be solved if one-time operation is carried out, and the field management of crops is more convenient.

The pesticide fertilizer capable of killing insects at intervals takes the block fertilizer units as the minimum unit, the pesticide cake and the top dressing cake are superposed in the vertical direction, the pesticide layer structure of the pesticide cake is decomposed after the pesticide cake is in contact with water, and the pesticide cake is dispersed into the range of fertilizer application/insect killing of crops from the block fertilizer units: because the solubility of the pesticide cake is different from that of the top dressing cake, and the massive fertilizer units are fixed by pressing andor degradable materials instead of adhesives, the composition particles of the pesticide cake decomposed in water can continuously flow to the pesticide application part needing disinsection, and a small amount of the composition particles of the pesticide cake remained in the top dressing cake do not influence the top dressing of the top dressing cake. After the pesticide cake is completely dispersed, a large amount of fertilizer contained in the additional fertilizer cake is gradually dissolved, and the particles of the additional fertilizer cake roll to the fertilizing part of the additional fertilizer after the additional fertilizer cake is dissolved due to the large particle size of the additional fertilizer cake, so that the additional fertilizer is realized.

Meanwhile, the topdressing cake has a certain thickness, so that the lower massive fertilizer units cannot be dissolved in advance.

In addition, for the fixation of a multilayer structure formed by stacking a plurality of block-shaped fertilizer units, the cost is low and the transportation and the storage are easy through pressing and/or degradable materials.

Preferably, the medicine cake and the top dressing cake are both of umbrella-like structures. The umbrella-like structure is easy for the fertilizer of the medicine cake/additional fertilizer cake to break away from the massive fertilizer unit and enter the medicine/fertilizer application position as soon as possible after the medicine cake/additional fertilizer cake breaks down when the water structure is met.

When the insecticide-fertilizer fertilization/insect killing device capable of killing insects at intervals is used, the insecticide cake on the surface layer of the blocky fertilizer unit is subjected to certain water pressure impact to be fertilized/insect killing.

In the insecticide-fertilizer capable of killing insects at intervals, the insecticide cake and the top dressing cake are overlapped in the vertical direction by utilizing the characteristic that the solubility of the insecticide cake and the solubility of the top dressing cake are different, the insecticide and the top dressing of crops can be realized by one-time fertilization, and the secondary interval insecticide and the secondary interval top dressing of the crops can be realized by overlapping a plurality of block-shaped fertilizer units without secondary fertilization and secondary insecticide. The cost of manpower and material resources is saved, and the manufacturing and using cost is lower.

In the pesticide fertilizer capable of killing insects at intervals, the top dressing cake comprises a top dressing block, and the top dressing block is formed by mixing and pressing a fertilizer and a natural high polymer material.

Natural polymer materials such as chitosan or chitin and other biological cellulose can form a polymer network system when meeting water, can absorb a large amount of water, and the natural polymer materials in the top dressing block convert the top dressing block into a gel block containing fertilizer under the action of the water, so that the completeness of the top dressing block can be ensured within a certain number of days, and the top dressing block can provide enough action time for the pesticide; and because the natural polymer material has limited performance, the gel block containing the fertilizer can gradually lose water until the gel block is disintegrated, and the dispersed hydrogel fragments containing the fertilizer can leave the massive fertilizer units and fall to the root of the crop under the action of the environment, thereby realizing topdressing.

In the insecticide fertilizer capable of killing insects at intervals, the fertilizer of the top dressing block comprises 0-50 parts of nitrogen, 0-15 parts of phosphorus and 0-20 parts of potassium by mass.

The crop growth needs fertilizer containing nitrogen, phosphorus and potassium elements. The nitrogen element is a core element of mineral nutrients necessary for the growth of crops, and taking grapes as an example, the nitrogen requirement in the growth process of the grapes is the largest, and the nitrogen element can increase the photosynthesis of the grapes, promote the growth and improve the fruit quality. The nitrogen fertilizer is mainly applied to the grapes in the early growth stage, so that the growth of branches and tendrils and the development of flower ears can be promoted, and preparation is made for later fruiting.

Further, the mass ratio of nitrogen, phosphorus and potassium in the fertilizer of the top dressing block is (0.5-0.8): (0.5-1.5): (1.5-1.8).

In the process of grape vine growth, the high-potassium fertilizer used in the early stage contains more nitrogen, and after sunlight shines on a shallow ground, sufficient water and sufficient fertilizer inevitably grow at high ground temperature. Therefore, the nutrient substance proportion of the top dressing block fertilizer can be adaptively adjusted: greatly reduces the proportion of nitrogen elements and improves the proportion of phosphorus and potassium elements which can improve the sweetness of grape fruits. Meanwhile, as a plurality of pesticides can cause the nitrogen element of the fertilizer to be lost, the unnecessary loss can be reduced by reducing the proportion of the nitrogen element in the fertilizer.

In the insecticide fertilizer capable of killing insects at intervals, the insecticide cakes are dispersed or dissolved in water and leave the block fertilizer unit, and the additional fertilizer cake begins to dissolve after the insecticide cakes leave the block fertilizer unit.

In order to prevent the topdressing cake from being dissolved in advance, the structure of the pesticide cake needs to be broken and dispersed in time, so that the pesticide cake can be dispersed in water or dissolved in water, so that the pesticide cake composition particles can leave the block-shaped fertilizer unit in time, meanwhile, the topdressing cake is difficult to dissolve in water, the structure of the pesticide cake is guaranteed to be completely broken, and the topdressing cake can be dissolved only after the pesticide leaves the block-shaped fertilizer unit.

In order to prevent the pesticide cake from dispersing untimely when dissolved, so that the composition particles of the pesticide cake excessively permeate into the topdressing cake to influence the actual pesticide effect dosage of the pesticide cake, the pesticide cake consists of pesticide and sparse particles with porous structures, and the pesticide and the sparse particles with porous structures are uniformly mixed; the medicine cake contains 0.1-2% of insecticide by mass percent.

After the insecticide is sufficiently mixed with the dispersed particles having a porous structure, a cake can be formed by pressing. The structure of the pesticide cake is quickly disintegrated after meeting water, the pesticides dispersed in the porous structure of the sparse particles and the pesticides not dispersed in the porous structure of the sparse particles are quickly adsorbed by the sparse particles, and the sparse particles adsorbed with the pesticides are dispersed and leave the massive fertilizer units due to the quick disintegration of the structure of the pesticide cake. Part of the scattered particles adsorbed with the insecticide may remain on the top dressing cake, but because the scattered particles adsorbed with the insecticide have large volume and are difficult to be stably connected with the top dressing cake, the time for adhering the scattered particles to the top dressing cake is short, and the scattered particles adsorbed with the insecticide still can be separated from the top dressing cake and enter the application range.

In the pesticide fertilizer capable of killing insects at intervals, the sparse particles are biological bacterial manure or humic acid, and the particle size of the sparse particles is 0.5-2mm.

Biological bacterial fertilizers such as Bacillus thuringiensis, bacillus fluorescens, bacillus saxifragi and Bacillus popilliae, and the bactericidal effect of the fertilizer can be further improved by mixing the biological bacterial fertilizers with insecticidal, bactericidal, herbicidal and plant biological regulation activities and pesticides.

Or the sparse particles are at least one of dried chicken manure or humic acid, and the particle size of the sparse particles is 0.5-2mm.

The natural porous structure of humic acid is easy to adsorb the pesticide, other components are not introduced to pollute the land, the grain diameter of the dispersed grains is controlled within the range of 0.5-2mm in order to facilitate the preparation and the forming of the pesticide cake and prevent the overlarge dispersed grains from adsorbing too much pesticide to influence the uniform application of the pesticide.

Preferably, the evacuation particles are chicken manure.

The dried chicken manure is low in price and wide in source, and the preparation cost of the medical fertilizer can be reduced. Nor does it introduce a possible source of contamination.

In the insecticide-fertilizer capable of killing insects at intervals, the insecticide comprises at least one of chlorantraniliprole and monosultap.

The chemical structure of chlorantraniliprole has a brand-new insecticidal principle which any other insecticides do not have, and can efficiently activate an insect ryanodine (muscle) receptor. Excessive release of calcium ions in calcium stores in cells leads to paralysis and death of insects, and has high activity to larvae, wide insecticidal spectrum and good persistence. Chlorantraniliprole is poorly soluble in water. Monosultap is an organic compound with a molecular formula of C ₅ H ₁₂ NNaOS ₄ Molecular weight 333.402, white crystalline solid. It also has certain fumigating effect, and can be dissolved in water.

The medicinal cake can be prepared from chlorantraniliprole by pressing, so that the medicinal cake is easy to disperse after being impacted by water; when the monosultap is used as the medicine cake, the medicine cake is in a structure which is easily dissolved in water.

Furthermore, in order to improve the insecticidal effect of the medicinal cake and optimize the structure of the medicinal cake, the insecticide of the medicinal cake is formed by mixing chlorantraniliprole and monosultap according to the ratio of 1: 1, at the moment, the monosultap is decomposed when meeting water, and the structure of the medicinal cake is quickly collapsed.

Preferably, the insecticide-fertilizer capable of killing insects at intervals comprises two vertically-arranged massive fertilizer units, the massive fertilizer units arranged below comprise anti-seepage medicine cakes and basic cake fertilizers which are arranged from top to bottom, the anti-seepage medicine cakes are medicine cakes provided with organic fertilizer anti-seepage rings, and the basic cake fertilizers comprise anti-seepage bases and additional manuring cakes covering the anti-seepage bases.

The insecticide cake, the additional fertilizer cake, the anti-seepage insecticide cake and the basic layer cake fertilizer are sequentially arranged from the vertical direction to the bottom, and considering that the first-time insecticide effect and the second-time insecticide effect are different in actual field operation, the insecticide components and the insecticide concentration of the insecticide cake and the anti-seepage insecticide cake can be different, preferably, the insecticide concentration of the insecticide cake is higher than the insecticide concentration of the anti-seepage insecticide cake. Similarly, because of the difference of the purposes of the first dressing and the second dressing, the concentrations and the proportions of the fertilizers of the dressing cake and the basic cake are also different.

The additional fertilizer cake has a certain thickness and forms a gel block when meeting water, so that the medicine cake in the anti-seepage medicine cake cannot be dissolved in advance before the additional fertilizer cake leaves the massive fertilizer unit, and an organic fertilizer anti-seepage ring is further arranged on the anti-seepage medicine cake to prevent the medicine cake in the anti-seepage medicine cake from being dissolved in advance due to the dissolution or dispersion of the medicine cake in the massive fertilizer unit above and the additional fertilizer cake, so that the medicine cake in the organic fertilizer anti-seepage ring is protected, and the organic fertilizer anti-seepage ring has small influence on crops and cannot cause pollution after the anti-seepage medicine cake collapses.

In the pesticide fertilizer capable of killing pests at intervals, the anti-seepage base of the base layer cake fertilizer consists of humic acid, and the height of the anti-seepage base is 0.8-2cm.

The anti-seepage substrate can prevent the topdressing cake of the basic-layer cake fertilizer from being dissolved in advance due to direct contact with the soil, so that the overgrowth of crops and the early loss of the pesticide fertilizer are caused, and the humic acid is lower in water solubility than the fertilizer, so that the influence on the crops is smaller due to the lower content of nutrient substances even if the humic acid is dissolved.

In addition, the topdressing cake of the basal cake can adjust the proportion of nutrient substances and can be used as a coloring fertilizer for fruit trees.

Preferably, in order to ensure that the structures of all the layers of the pesticide fertilizer can be smoothly dispersed, the areas of all the layers can be gradually reduced along the vertical direction.

The application of the pesticide fertilizer capable of killing insects at intervals is to place the pesticide fertilizer near the roots of crops in a state that pesticide cakes face upwards for use; or fixing the pesticide fertilizer on the crop stem and enabling the pesticide cake to be directly contacted with the crop stem for use.

In the pest control of crop, often need directly use the insecticide to the plant diseases and insect pests position in order to guarantee better insecticidal effect, place the medicine fertilizer near crop root with medicine cake state up and use and can be to crop root direct action, the medicine fertilizer of this application can be with medicine cake and crop stem direct contact and be fixed in on the crop stem simultaneously, direct action is the focus from this, and provide nutrient substance through subsequent additional fertilizer cake high efficiency to the crop stem, supply abundant nutrient substance with the stem, promote the blooming and the result of stem.

(1) In the insecticide-fertilizer capable of killing insects at intervals, the insecticide cakes and the topdressing cakes are overlapped at intervals in the vertical direction by utilizing the characteristic that the solubilities of the insecticide cakes and the topdressing cakes are different, and the secondary interval insecticide-fertilizer and the secondary interval topdressing for crops can be realized by one-time fertilization without secondary fertilization or secondary insecticide. The cost of manpower and material resources is saved, and the manufacturing and using cost is lower.

(2) In the insecticide-fertilizer capable of killing insects at intervals, the proportion of the nutrient substance nitrogen element of the top dressing block fertilizer is greatly reduced, the problem that crops grow in vain with shallow roots and large plants is avoided, and meanwhile, as a plurality of insecticides can cause the nitrogen element of the fertilizer to run off, the proportion of the nitrogen element in the fertilizer is reduced, and unnecessary loss can be reduced.

(3) In the pesticide fertilizer capable of killing insects at intervals, the natural polymer material in the top dressing block converts the top dressing block into a gel block containing fertilizer under the action of water, so that the completeness of the top dressing block can be ensured within a certain number of days, and enough action time is provided for pesticides; and because the natural polymer material has limited performance, the gel block containing the fertilizer can gradually lose water until the gel block is disintegrated, and the dispersed hydrogel fragments containing the fertilizer can leave the massive fertilizer units and fall to the root of the crop under the action of the environment, thereby realizing topdressing.

(4) In the insecticide-fertilizer capable of killing insects at intervals, the insecticide cake comprises chlorantraniliprole and/or monosultap, so that the composition structure and the solubility of the insecticide cake can be flexibly adjusted according to actual needs, and more use scenes and requirements can be met.

(5) In the pesticide fertilizer capable of killing insects at intervals, the pesticide components and the concentrations of the pesticide cakes and the anti-seepage pesticide cakes can be adjusted correspondingly according to different effects of first-time killing insects and second-time killing insects in actual field operation. Similarly, due to the difference of the purposes of the first topdressing and the second topdressing, the fertilizer concentration and the proportion of the topdressing cake and the base cake can be set differently.

(6) In the insecticide-fertilizer capable of killing insects at intervals, the impermeable substrate can prevent the topdressing cake of the basic cake fertilizer from being dissolved in advance due to direct contact with the soil, so that the excessive growth of crops and the early loss of the insecticide-fertilizer are caused, and the humic acid is lower in solubility when meeting water than the fertilizer, so that the influence on the crops is smaller due to the lower content of nutrient substances even if the humic acid is dissolved.

As can be seen from Table 1, the decomposition rates of the insecticide-fertilizer items for the examples 1-9 which can kill insects at intervals are all lower than 5%, and the stability is good. The decomposition rate is high due to the high content of monosultap, and the decomposition rate is influenced by the high content of nitrogen in the fertilizer.

The insecticide fertilizers of examples 1 to 9 which can be used for alternate-period insecticide were subjected to field growth test

The test crops are Kyoho grapes widely planted in Zhejiang, the Kyoho grapes are randomly and evenly divided into 10 groups of 300 plants, each group is planted for one mu, and the Kyoho grapes are planted in adjacent planting places. The application of the base fertilizer refers to conventional field management, and the fertilizing amount of the base fertilizer is as follows: 3000-4000 kg of organic fertilizer can be applied per mu in the fertilizing amount, and 1.5-2.0 kg of phosphorus-calcium fertilizer is applied in combination. Before grape fruit setting, 9 groups of insecticide fertilizers which can kill insects in intervals of examples 1-9 are randomly selected and applied, the dosage is 50kg per mu, and the application method is that the insecticide fertilizers are placed under the roots of the grapevines and water is used for impacting the surfaces of the insecticide fertilizers. The test methods of the comparative example groups were as follows: before the grapes are set, carrying out first insecticidal application on the comparative example group; after the grapes are fruited, performing primary topdressing on the comparative example group; after 15 days of the first top dressing, carrying out second pesticide application on the comparative example group, and when the grapes begin to be colored after the second pesticide application, carrying out second top dressing on the comparative example group, wherein the pesticide and top dressing amount of the comparative example group is in reference to example 7; other field management modes are carried out according to the conventional method; the resulting grape fruits were collected at the harvest stage and tested for each item. The test method is as follows:

average mass of fruit pieces: randomly selecting 5kg of the collected grape fruit clusters in each group, respectively testing the quality of the fruit grains of the single fruit, and averaging;

sugar degree: randomly selecting 5kg of grape fruit clusters collected in each group, respectively testing the sugar degree of each single fruit, and averaging;

appearance: and classifying the appearance grade of each group of collected grape clusters according to the appearance color and the size of the fruit grains, and measuring and calculating the first-grade product rate. The test results were as follows:

TABLE 2 field growth test results for examples 1-9 and comparative example 1
