Description

Technical Field

[0001] The present invention relates to the technical field of herbicidal drug compositions, in particular to a herbicidal drug composition. Background Art

[0002] The development of herbicides has gone through a process from single ingredients to compound compositions. In the early days, farmers mainly relied on single-ingredient herbicides to control weeds, but these herbicides often had problems such as narrow weed control spectrum, slow efficacy, and easy resistance. With the continuous advancement of agricultural technology, scientists began to study the compounding of herbicides with different mechanisms of action to expand the weed control spectrum, improve weed control effects and reduce the cost of use.

[0003] With the continuous development of global agricultural production, the demand for herbicides is also increasing, especially in some large-scale planting areas, such as corn fields, soybean fields, cotton fields, etc. Weed control has become a key factor affecting crop yield and quality. At present, many herbicides are highly toxic when used. They can not only kill weeds but also damage the soil environment. They will remain on the plants. If they are not cleaned up, it will affect the use of the plants.

[0004] Therefore, we propose a herbicidal drug composition to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a herbicide composition to solve the problem mentioned in the above background technology that many herbicides currently used have high toxicity, not only can kill weeds but also damage the soil environment, and will remain on the plants. If not cleaned up, it will affect the use of the plants.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A herbicidal drug composition, wherein the active ingredient is wood vinegar, a biological plant extract, and the adjuvants include a surfactant and water, wherein the proportion of the surfactant is 0.5%-1.5% of the wood vinegar, and the proportion of water to the wood vinegar is 1:500-1:1000.

[0008] In a further embodiment, the wood vinegar is extracted from wood, such as waste wood from corn cobs, pine cones, peach branches, apple branches, and hardwood.

[0009] In a further embodiment, the wood vinegar is prepared by the following steps:

[0010] S1. Raw material preparation: Recycle various waste wood and classify them according to their types, among which fruit tree wood is the best;

[0011] S2. Preparation environment: sort the wood and place it in a retort, and heat it in an air-tight or oxygen-limited environment to cause the wood to undergo pyrolysis;

[0012] S3, heating: through continuous heating, the temperature rises, the moisture in the wood, volatile organic matter such as wood vinegar and charcoal and other products will be precipitated in sequence;

[0013] S4, collection: In the process of S3, the gas condensate generated during the pyrolysis process is collected to be the crude wood vinegar.

[0014] In a further embodiment, the surfactant is a non-ionic surfactant, specifically polyethylene glycols and alcohols.

[0015] In a further embodiment, the ratio of the wood vinegar to the surfactant in water is 1:0.015:500.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the preparation of the herbicidal drug composition, wood vinegar and a surfactant are mixed in water for preparation, wherein the wood vinegar is extracted from discarded wood in nature. In terms of material selection, waste is utilized, nature is restricted by nature, and natural circulation is used to protect the environment. The wood vinegar is a natural plant protection agent with good weed control effect. After being prepared according to the ratio, it will not have adverse effects on the soil and the surrounding environment, and has the advantages of strong selectivity and low toxicity to mammals. It has low destructiveness to nature when used and is more environmentally friendly after use. DETAILED DESCRIPTION

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] The herbicidal composition of the present invention comprises an active ingredient and an adjuvant; the active ingredient is wood vinegar, which is a biological plant extract; the adjuvant comprises a surfactant and water; the ratio of wood vinegar to surfactant in water is 1:0.015:500; when in use, firstly, waste wood from nature is collected, preferably fruit trees, such as corn cobs, pine cones, peach branches, apple branches, hard miscellaneous wood, etc.; the collected wood is placed in a retort, which is preferably insulated from air; the interior is heated; after heating, the wood undergoes a pyrolysis reaction; as the temperature continues to rise, moisture and volatile organic matter such as wood in the wood are decomposed; Vinegar liquid and the like will evaporate in sequence, and the gas can be condensed and collected during the volatilization process to obtain wood vinegar. After obtaining the wood vinegar, an auxiliary agent is selected. Generally, a non-ionic surfactant is selected to mix the wood vinegar and water. Non-ionic surfactants such as polyethylene glycols and alcohols do not ionize in water, have good stability, are highly adaptable to hard water and acid-base environments, and are low in irritation. They are suitable for use with wood vinegar to enhance the weed control effect. After adjusting the wood vinegar and surfactant in water, use a spray bottle to evenly spray them on the location where weeds need to be removed. Ensure uniformity when spraying, and avoid spraying on the surrounding flowers and plants.

[0022] By configuring different concentrations of wood vinegar during spraying, the effective concentration of wood vinegar for barnyard grass in rice fields is between 2.5‰ and 5‰. This concentration range can effectively inhibit the survival rate and growth of barnyard grass while ensuring the normal growth of rice seedlings. When the concentration of wood vinegar in the field is 2.5‰ to 5‰, the inhibition effect of wood vinegar on barnyard grass in the tillering stage of rice is significant, and the inhibition rate can reach 68.3% to 87.4%. This shows that wood vinegar has a significant weed control effect at an appropriate concentration, and when wood vinegar with a concentration of 5‰ is used in rice fields, it will not have a significant impact on the plant height and yield of rice. When 10 to 500 times of wood vinegar is sprayed on the lawn, it has no significant effect on the soil pH value.
