Technical Field
[0001] The present invention relates to the technical field of pesticide preparation, and in particular to a pesticide preparation method for improving the application accuracy of liquid pesticide preparations. Background Art
[0002] Pesticides are important strategic materials and essential materials for ensuring high yield and quality of crops. Pesticides are ultimately delivered to users in the form of preparations. The use of pesticides is usually calculated by dosage. That is, how much preparation or active ingredient is used per mu or per hectare. In production, it is more common to use how much preparation per mu. There are currently three main forms of pesticide preparation packaging. The first is to use large packages, such as 1 to 5 kg / liter per package. One bottle can spray more than 10 mu or dozens of mu, suitable for large-scale spray equipment, such as drones or motorized sprayers. The second is a small package of about 1 to 10 grams, such as 1 bag / bottle per bucket of water, mainly suitable for field spraying with backpack sprayers. The third is a medium-sized package of 50 to 200 grams per bag / bottle, and one bottle or half a bottle can be used for 1 mu.
[0003] Regardless of the type of spray equipment used, the amount of liquid sprayed per acre can be calculated. For example, a drone can accurately measure 1.5 to 4L of liquid for one acre of land; a backpack sprayer can measure 2 to 3 barrels of water per acre. Due to the large differences in the resistance levels of pests in different places, the actual dosage used varies greatly. For small-scale farmers with only a few acres of land, small backpack sprayers are often used to spray pesticides. It is difficult to accurately distribute the appropriate dose of pesticides into the sprayer. For small-package pesticides, although the distribution of the agent is simple, it is difficult to increase the amount or reduce the dosage. For medium or large packages, because farmers are unwilling or difficult to find a suitable measuring device to accurately measure the pesticide, they usually use bottle caps to estimate the dosage, and the dosage error is large, which greatly affects the prevention effect or safety.
[0004] Pesticides are the most important controlled substances for agricultural ecological environment protection. Using too high a dosage will threaten ecological safety; using insufficient dosage will not have a preventive effect. Since 2016, we have been committed to reducing the amount of pesticides and increasing their efficiency. The precise use of pesticides is the direction of plant protection workers' efforts now and for a long time to come. It is very important to establish a simple, efficient, and precise pesticide configuration method suitable for current agricultural production. Summary of the invention
[0005] The purpose of the present invention is to provide a pesticide preparation method for improving the dosage accuracy of liquid pesticide preparations, which is simple, efficient and suitable for current agricultural production practices.
[0006] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:
[0007] The present invention provides a method for preparing a pesticide for improving the application accuracy of a liquid pesticide preparation, comprising the following steps:
[0008] (1) Determine the number of barrels of water required for each pesticide formulation package based on the pesticide formulation package and the amount of pesticide formulation used per unit area;
[0009] (2) according to the number of barrels determined in step (1), a small water container is used, the amount of water that fills the small container is defined as one portion, and clean water for preparing the mother solution is taken according to the number of barrels determined in step (1), and the pesticide and the clean water are mixed to obtain the mother solution;
[0010] (3) After adding water to the sprayer, use the small water collection container used in step (2) to measure 1 portion of the mother solution and add it to the sprayer, continue to add water until the sprayer is full, and spray the pesticide;
[0011] (4) After the first spraying, add water to the sprayer and then take another portion of the mother solution and add it to the sprayer, and continue to add water until the sprayer is full;
[0012] (5) Repeat step (4) until all the mother solution prepared in step (2) is sprayed.
[0013] Preferably, the pesticide preparation method is applicable to a personal backpack sprayer.
[0014] Preferably, the number of barrels used in step (1) is the number of sprayer barrels required for spraying pesticides per unit area.
[0015] Preferably, the small container in step (2) is a container of 500 to 1000 ml, the amount of clean water measured is an integer multiple of the capacity of the small water-taking container, and the multiple is the same as the number of buckets used in step (1), and the small container is a cup, a ladle or a jar.
[0016] Preferably, the amount of water added in step (3) is 45-55% of the capacity of the sprayer, and the amount of the mother liquor used is the same as the capacity of the small container used to take water in step (2).
[0017] Preferably, the amount of water added in step (4) is 30-35% of the capacity of the sprayer, and the amount of the mother liquor used is the same as the capacity of the small container used to take water in step (2).
[0018] The present invention provides a method for preparing a pesticide for improving the application accuracy of a liquid pesticide preparation, comprising the following steps: (1) determining the number of barrels of water required for each preparation package according to the pesticide preparation package and the amount of the pesticide preparation per unit area; (2) using a small water-taking container according to the number of barrels determined in step (1), stipulating that the amount of water that fills the small container is one portion, taking clean water for preparing a mother liquid according to the number of barrels determined in step (1), mixing the pesticide and the clean water to obtain a mother liquid; (3) after adding water to a sprayer, using the small water-taking container used in step (2) to measure one portion of the mother liquid and adding it to the sprayer, continuing to add water until the sprayer is full, and spraying the pesticide; (4) after the first spraying is completed, adding water to the sprayer, taking another portion of the mother liquid and adding it to the sprayer, continuing to add water until the sprayer is full; (5) repeating step (4) until all the mother liquid prepared in step (2) is sprayed.
[0019] The industry pain points solved by this invention
[0020] (1) In the conventional process of pesticide preparation, farmers do not use measuring instruments and basically rely on estimation, resulting in large errors in the amount of pesticide used. Insufficient dosage will not achieve the control effect, and increasing the dosage will increase the risk of pesticide damage. This method uses tools that are available at hand to achieve accurate pesticide preparation.
[0021] (2) In the past, farmers mainly considered the amount of pesticides needed for each sprayer, and there was no better measure for how to measure the pesticides, resulting in serious waste and pollution of pesticides. The present invention takes how to use the entire package at one time as a premise, ensuring that when preparing pesticides, there is less waste of pesticides and less environmental pollution caused by the packaging, thus contributing to agricultural environmental protection.

[0034] The technical solutions provided by the present invention are described in detail below in conjunction with the embodiments, but they should not be construed as limiting the protection scope of the present invention.
[0035] Example 1
[0036] A pesticide preparation method for improving the application accuracy of liquid pesticide preparations
[0037] (1) Choose a backpack sprayer that suits you and clearly know the amount of spray liquid to be used for one mu of land, that is, whether one bucket of water, two buckets of water or three buckets of water are needed to spray one mu of land.
[0038] (2) Select the correct pesticide formulation packaging based on actual needs and clearly determine how much pesticide dosage is required for one acre of land.
[0039] (3) Prepare a pair of latex gloves, a 5-10 liter plastic bucket and a 500-1000 ml clean container such as a plastic cup, a ladle, an enamel pot, etc.
[0040] (4) Wear gloves and pour the corresponding amount of clean water into a small bucket using a plastic cup according to the number of buckets required for spraying per acre. If you plan to use 3 sprayers to spray one acre of land, pour 3 cups of clean water into a small bucket. Keep half a cup of clean water for later use each time.
[0041] (5) Pour the whole bag or bottle of pesticide into a plastic bucket filled with clean water according to the required pesticide dosage per mu. For small-packaged pesticides, if one bag is needed per mu, pour one bag; if three bags are needed, pour three bags. For medium-sized packages, if one bottle is needed per mu, pour one bottle; if two bottles are needed, pour two bottles. If only half a bottle is needed per mu, first add twice the amount of liquid pesticide to the small bucket, and then add the whole bottle of pesticide (as shown in Table 1).
[0042] (6) Rinse the entire pesticide bottle or bag in the prepared pesticide solution barrel, then rinse it twice with half a cup of reserved clean water. Add the rinse solution and the remaining clean water into the matching pesticide solution barrel, and stir the prepared mother solution evenly with a wooden stick.
[0043] (7) Add half a bucket of water into the sprayer, pour out 1 cup of the prepared mother liquor and add it to the sprayer, then add clean water to the sprayer, stirring while adding until the entire sprayer is filled.
[0044] (8) Start spraying pesticides in the usual manner.
[0045] (9) After the first bucket of liquid medicine is sprayed, add 1 / 3 bucket of clean water to the empty bucket, then pour 1 cup of the prepared mother liquid into the sprayer, then add clean water, stirring while adding, until it is full. And so on.
[0046] (10) Collect the rinsed pesticide bottles or bags and send them to a professional location for disposal when the time is right.
[0047] Table 1 Precise configuration method of pesticides at different dosages
[0048]
[0049] Test Example 1
[0050] How to spray 1 bottle (75 ml) of pendimethalin microcapsule suspension evenly on the surface of 1 acre of dry direct-seeded rice field.
[0051] Materials required: 1 clean plastic bucket of about 5 liters, 1 standard 15-liter backpack electric sprayer, 1 500 ml used enamel tank, and 1 bottle of 450g / L pendimethalin microcapsule suspension.
[0052] Prepare mother liquor: use an enamel tank to scoop 2 full tanks of clean water into a small plastic bucket, unscrew the cap of the herbicide pendimethalin bottle, tear off the sealing film on the bottle mouth, pour all the pendimethalin into the small bucket, then take another enamel tank of clean water, rinse the remaining medicine in the pendimethalin plastic bottle into the small plastic bucket, stir the medicine in the plastic bucket with a wooden stick to mix it evenly, cap the empty pendimethalin bottle and collect it for processing.
[0053] Prepare the spray solution: Pour about 5 liters of water into the sprayer, use the enamel tank to scoop a full cup of the prepared pendimethalin stock solution and pour it into the sprayer, while adding clean water. After pouring the mother solution, continue to add clean water and continue to stir the solution with a wooden stick until 15 liters of clean water are added.
[0054] Spraying: Turn on the power switch to continue mixing the liquid medicine in the medicine box, open the valve on the spray rod and start spraying the soil of the rice field after sowing.
[0055] Problem to be solved: Compared with measuring with a bottle cap or a syringe, this method will not cause residue on the inner wall of the medicine bottle, nor will it cause differences in the amount of herbicide liquid in different sprayers due to inaccurate estimation.
[0056] Efficacy: Compared with the traditional method, the uniformity of herbicide preparation in this method is improved by 20%, the weed control efficiency is improved by 18%, and the herbicide loss is reduced by 15%.
[0057] As can be seen from the above embodiments, the present invention provides a method for preparing pesticides for improving the precision of liquid pesticide preparations, comprising the following steps: (1) determining the number of barrels of water required for each preparation package according to the pesticide preparation package and the amount of pesticide preparation per unit area; (2) using a small water-taking container according to the number of barrels determined in step (1), stipulating that the water filling the small container is one portion, taking clean water for preparing the mother liquid according to the number of barrels determined in step (1), mixing the pesticide and the clean water to obtain the mother liquid; (3) after adding water to the sprayer, using the small water-taking container used in step (2) to measure 1 portion of the mother liquid and adding it to the sprayer, continuing to add water until the sprayer is full, and spraying the pesticide; (4) after the first spraying is completed, after adding water to the sprayer, taking another portion of the mother liquid and adding it to the sprayer, continuing to add water until the sprayer is full; (5) repeating step (4) until all the mother liquids prepared in step (2) are sprayed. The method of the present invention can use tools available at hand to achieve precise preparation of pesticides. The invention takes how to use the whole package at one time as a premise, ensures less pesticide waste and less environmental pollution caused by the package when preparing pesticides, and contributes to agricultural environmental protection.
[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
