Description
Technical Field
The invention belongs to the field of pesticide herbicides, and particularly relates to a herbicide adjuvant mixed with a herbicide for use.
Background
Herbicides are agents which cause complete or selective death of weeds, also known as herbicides or herbicides, and are used to kill or inhibit the growth of plants. Chemical agent capable of killing weed or harmful plant without affecting normal growth of crop. Can be used for preventing and controlling farmland weeds or killing weeds or shrubs in non-agricultural lands. They can be classified into selective herbicides and biocidal herbicides according to their action characteristics. Selective herbicides are those which selectively kill certain species of plants while not harming other species of plants at the dosage and concentration range used.
The herbicide has certain influence on plants, pathogens, soil microorganisms and environment in the using process. But also indirectly cause harm to human body.
The application of the herbicide causes land pollution, and after the herbicide is sprayed on farmlands, the herbicide components which are not absorbed by weeds can be free and exist in the soil. At present, most of the used chemical herbicides belong to long-residue type, the residue period of the chemical herbicides in soil can reach more than 36 months generally, and 20-70 percent of the commonly used herbicides in production can remain in soil for a long time, so that ten kinds of soil, underground water and pollution are caused.
The use of the herbicide can cause soil quality reduction, organic microorganism action reduction, soil pH value increase, nitrogen, phosphorus and potassium nutrient reduction in soil and multiple soil diseases.
The herbicide is not beneficial to crop production even if being used for a long time, the crop can absorb and accumulate the herbicide in the growth period, the biological tissue of the crop can be damaged to a certain degree, certain nutrient elements which the crop needs cannot be synthesized, and certain nutrient components in the crop fruits are lost. Under the condition of normal dosage, the herbicide has a certain inhibiting effect on crops such as wheat, corn, cotton and the like, and if the herbicide is unreasonably used, the normal development and maturity of the crops are affected, so that recessive yield reduction is caused. Any herbicide has a certain residual period in soil, and some herbicides even reach 3-5 years, when the residual amount of the herbicide is large, phytotoxicity is easy to generate when sensitive crops are planted in the next crop, plants cannot grow normally, and serious failure in harvest is caused.
At present, the use of phosphorus-potassium fertilizer and herbicide in large dose is the main reason for the gradual rise of the pH value of soil and the accumulation of saline-alkali components in a surface soil layer. Meanwhile, the soil is hardened seriously, organic matters are reduced, the germination and seedling emergence of crops are slow, root diseases and blight of the crops occur in a large quantity, saline-alkali components on the surface layer of the soil are accumulated, the salinization is serious, the weeding effect is poor, and the phytotoxicity is more.
Causes a plurality of saline-alkali components on the surface layer of the soil and has high pH value as follows:
firstly, the phosphorus and potassium salt in a deep soil layer of 20-30 cm is turned into soil with 8-10 cm of the surface layer of the soil in autumn turning.
Secondly, the saline-alkali components in the deep soil layer below 40 cm accumulated in the soil moisture gathering process after freezing are thawed in the first spring, and the soil rises to the soil layer along with the soil capillary, so that the saline-alkali of the surface soil layer is further increased.
Furthermore, there are also cases:
1. the soil hardening is serious, organic matters are reduced, the soil aggregate structure is unreasonable, the microbial action is reduced, the germination and seedling emergence of crops are poor, and the seedling growth is slow.
2. Various root diseases and blight occur in large quantities,
3. the pH value of the soil is increased year by year (the area with the pH value below 7.5 is 15 percent, the land with the pH value above 7.5-8.5 is 75-80 percent, the pH value is 9.0 is 10 percent), saline and alkaline components on the surface layer of the soil are accumulated, and the salinization is serious.
4. When the pH value of the soil is 7, 5-8 and 5, the herbicide effect is poor, the phytotoxicity is more likely to occur, and the use utilization rate of various fertilizers is low.
Therefore, the applicant proposes a herbicide adjuvant, and the herbicide adjuvant and the herbicide are mixed together for use, so that the problems existing in the prior herbicide can be greatly improved.
By using the herbicide adjuvant proposed by the applicant and the existing herbicide application spray, the following effects can be achieved:
1. regulating water quality, increasing nitrogen and phosphorus fertilizer on soil surface, reducing herbicide consumption, and reducing phytotoxicity.
2. Improving soil, activating calcium ions in soil, replacing sodium ions in soil aggregates to discharge, reducing pH value and saline-alkali components of soil in a film, and improving germination and emergence rate.
3. The water retention improves the soil structure, keeps the surface layer saturated with water, achieves loose soil, has good air permeability and good heat preservation performance, improves the rate of emergence and promotes the growth of seedlings.
Disclosure of Invention
The invention aims to solve the technical problem that a large amount of herbicide is used, but the weeding effect cannot reach the expectation, and the main reasons are as follows through analysis:
1. the herbicide is an acidic compound which is not easy to dissolve in water, the pH value is 5.5-7.0, the herbicide can only be dissolved by 50-55% under the low-temperature condition, and the auxiliary agent can only be dissolved completely and the active ingredients of the herbicide cannot be completely dissolved when the herbicide is subjected to secondary dilution.
2. The effect of using well water to prepare the herbicide is poor. The pH value of well water is 7.8-8.6, the well water belongs to alkaline hard water, when the herbicide is applied, an acidic herbicide is added into the alkaline well water, a chemical reaction occurs, a large amount of bubbles are generated, the active ingredients of the herbicide are complexed with calcium and magnesium ions in water to form heavy salts and are fixed, and the weeding effect of the herbicide is reduced.
3. After the conventional herbicide is compounded, the pH value is 7.2-7.6, the herbicide is sprayed into the soil with the pH value of 7.5-8.5, the salt and alkali components on the surface layer of the soil are increased, the effective components of the herbicide are effectively decomposed and reduced, the weeding effect is reduced,
4. the soil has good adsorption effect on the herbicide, after the herbicide is sprayed, the herbicide is quickly adsorbed into soil granules, and after the soil is harrowed, a 4-6 cm soil sealing layer is formed, but the herbicide cannot be fixed by the soil.
When the seedling water is dripped, sufficient water dilutes the herbicide adsorbed into the soil, causing separation of the soil and the drug. Under the action of water pressure, the water moves left and right along with the water, so that the concentration of the herbicide in the side-row film is increased, and the seedling emergence of the side-row cotton is slow and weak. The fertilizer is produced under the action of gravity water, eluviation is performed in a soil layer with the thickness of 10-15 cm, roots are contacted with a medicine layer, the roots are not deeply pricked, deformed roots and root bark are swollen and cracked, various germs enter the xylem of cotton, and a large number of various root diseases and blight are caused (the blight is generated in a large number in 202 years, and the direct relation with the use of herbicides is realized). The occurrence of horizontal movement and leaching infiltration reduces the effective components of the soil herbicide and the weeding effect.
In order to achieve the above purpose, the present invention provides the following technical solutions:
