Description

Technical Field

[0001] This invention relates to the field of wheat cultivation, specifically to a method for degrading pesticide residues during wheat cultivation. Background Technology

[0002] In agricultural planting, pesticides and fertilizers are indispensable throughout the entire production process, from seed treatment to plant protection. This pollutes the environment, causes harmful pesticide residues, soil compaction, alters soil aggregate structure, and disrupts the ecological balance. Pest and disease control in wheat cultivation has always relied on the spraying of pesticide carriers to prevent diseases and pests and ensure crop growth. However, due to the long-term use of pesticide formulations, not only is the environment polluted, but the ecological chain is also damaged, soil fertility is reduced, the soil microbial environment is destroyed, compaction is exacerbated, and pesticide residues in crops exceed the standards. Long-term consumption of these crops seriously affects human health. Summary of the Invention

[0003] The purpose of this invention is to provide a method for degrading pesticide residues during wheat cultivation, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for degrading pesticide residues during wheat cultivation, comprising the following steps: Step W1: Mix wheat seeds with microbial fermentation liquid. The liquid microbial liquid and wheat are mixed evenly at a weight ratio of (3-5):100, air-dried, and then mechanically sown. Step W2 involves spraying the wheat planted in Step W1 with a formulated microbial inoculant solution, when the ambient temperature is above 10℃, the soil moisture is between 40% and 80%, and the wheat is in its greening stage. Step W3: Apply a reduced amount of pesticides, insecticides, and fungicides to the wheat treated in step W2. The pesticide base amount is halved and the mixture is evenly mixed and sprayed during the tasseling stage of the wheat. Step W4: Apply a single spray of the formulated carbon-based foliar liquid fertilizer to the wheat treated in Step W3 after the wheat has been pollinated. Step W5 involves applying a second application of a formulated carbon-based foliar liquid fertilizer to the wheat treated in step W4 during the mid-to-late stages of wheat grain filling.

[0005] Preferably, the microbial fermentation broth is made from pig manure and straw as raw materials, and the liquid and solid waste are separated from the solid-liquid mixture.

[0006] Preferably, the formulated microbial inoculant solution consists of solution A and solution B, which are mixed evenly at a weight ratio of 1:6 and then sprayed.

[0007] Preferably, liquid A is the liquid obtained by solid-liquid separation from pig manure and straw fermentation. The separated solid waste is mixed with water at a weight ratio of 1:50-80, stirred evenly, aerated for more than three days, and then filtered to obtain liquid B.

[0008] Preferably, the application of the reduced-dosage pesticides, insecticides, and fungicides begins on sunny days when the wheat is more than halfway through heading, on cloudy days when the wheat begins to flower, and is supplemented once after rain.

[0009] Preferably, the carbon-based foliar liquid fertilizer used for the first and second applications consists of microbial liquid A and liquid B, fermented brown sugar, potassium dihydrogen phosphate, M powder and N powder.

[0010] Preferred dosage: 50g of fermented brown sugar per mu, 100-200g of potassium dihydrogen phosphate per mu, and 0.3g each of M powder and N powder per mu.

Detailed Implementation

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Example 1 See Figure 1 A method for degrading pesticide residues during wheat cultivation includes the following steps: Step W1: Use microbial fermentation liquid to mix wheat seeds. Mix the liquid bacterial solution with wheat at a weight ratio of 4:100, dry in the shade, and then carry out mechanical sowing. The wheat will emerge fully after sowing. Spray a herbicide (a pesticide specified for testing) once when the wheat is 3-5 leaves before the new year to kill weeds. Among them, the microbial fermentation liquid is a liquid and solid waste separated from pig manure and straw through fermentation. Step W2 involves spraying the wheat treated with the formulated microbial inoculant solution during the wheat's greening-up period, with an ambient temperature of 10-20℃ and soil moisture of 40%-75%. In step W2, the microbial agent liquid sprayed consists of liquid A and liquid B, which are mixed evenly and sprayed at a weight ratio of 1:7, with 5 catties of liquid A and 35 catties of liquid B. The microbial fermentation liquid seed mix W1 is derived from liquid A separated from solid-liquid. The separated solid waste is mixed with water at a weight ratio of 1:70 and stirred evenly. After aeration for more than three days, the mixture is allowed to stand and then filtered to obtain liquid B. Step W3 involves spraying the wheat treated in Step W2 with a reduced amount of pesticides and fungicides (specified pesticides for testing). The pesticide base amount is halved and evenly mixed and sprayed. This is done during the wheat tasseling stage. Then, the reduced amount of pesticides and fungicides (specified pesticides for testing) for W3 is sprayed starting on sunny days when the wheat is more than halfway through heading, and on cloudy days when the wheat begins to flower. A second spray is applied after rain.

[0015] Step W4 involves applying a single application of a formulated carbon-based foliar liquid fertilizer to the wheat treated with W3 after pollination. Step W5 involves applying a second application of a formulated carbon-based foliar liquid fertilizer to the wheat treated with W4 during the mid-to-late stages of wheat grain filling.

[0016] The carbon-based foliar liquid formula used for both primary and secondary spraying consists of microbial solution A and solution B, fermented brown sugar, potassium dihydrogen phosphate, M powder, and N powder.

Wheat should be sprayed with a herbicide (a pesticide that has been specified for testing) once during the 3-5 leaf stage before the new year to kill weeds; Microbial fermentation liquid seed dressing uses pig manure and straw as raw materials for fermentation, and separates the liquid and solid waste into solid and liquid components. Step W2 involves spraying the wheat treated in Step W1 with a liquid microbial inoculant at an ambient temperature of 10-20℃ and a soil moisture content of 40%-80%, during the wheat's greening-up period. The formula microbial agent liquid consists of liquid A and liquid B, which are mixed evenly at a weight ratio of 1:6 and sprayed. The ratio of liquid A to liquid B is 5 catties and 30 catties respectively. The microbial fermentation liquid is derived from liquid A separated from solid-liquid. The separated solid waste is mixed with water at a weight ratio of 1:80, stirred evenly, aerated for more than three days, allowed to stand, and filtered to obtain liquid B. Step W3 involves spraying the wheat treated in Step W2 with a reduced amount of pesticides and fungicides (specified pesticides for testing). The pesticide base amount is halved and evenly mixed and sprayed. This is done during the wheat tasseling stage. Then, the reduced amount of pesticides and fungicides (specified pesticides for testing) is sprayed on sunny days when the wheat is more than halfway through heading, on cloudy days when flowering begins, and once more after rain.

[0020] Step W4: Apply a single spray of the formulated carbon-based foliar liquid fertilizer to the wheat treated in Step W3 after the wheat has been pollinated. Step W5 involves applying a second application of a formulated carbon-based foliar liquid fertilizer to the wheat treated in step W4, during the mid-to-late stages of wheat grain filling.

[0021] The formula carbon-based foliar liquid fertilizer for single and double application consists of microbial solution A and solution B, fermented brown sugar, potassium dihydrogen phosphate, M powder and N powder.

[0022] The dosage of fermented brown sugar is 50g per mu, potassium dihydrogen phosphate is 200g per mu, and M powder and N powder are each 0.3g per mu.

[0023] Wheat plant protection throughout its entire growth period has been completed, and pesticide residues in mature grains are approaching zero (see attached image). Figure 4 .
