Antitranspirant, and preparation and application thereof

Abstract

The invention discloses antitranspirant. The antitranspirant consists of the following raw materials in part by weight: 200 to 500 parts of liquid biochemical fulvic acid, 200 to 500 parts of dry alhagi alkaline essential oil, and 2 to 10 parts of abscisic acid; and the antitranspirant can be prepared by uniformly and fully mixing the components. The antitranspirant is applied to reduction of thetranspiration of crops. The antitranspirant has the advantages of high efficiency, and innocence and environment-friendliness and has effects on various crops.

Description

technical field [0001] The invention relates to a crop protection agent, in particular to an anti-transpiration agent and its preparation and application. Background technique [0002] According to statistics, the world's arid and semi-arid areas account for one-third of the earth's land area, and my country's arid and semi-arid areas account for about 50% of the country's land area, especially in northern my country. One of the important issues that scientists pay attention to. Plants mainly obtain water from the soil through well-developed root systems. Of these water, only about 1% of the water is used for their own metabolism, while the rest of the water is lost through transpiration. Most of the lost water is Expelled through the stomata, therefore, reducing the transpiration of plants is extremely important for drought resistance. In this field, anti-transpiration agents have played a great role in reducing the transpiration of plants, especially in arid regions, and ...

Problems solved by technology

[0004] The existing anti-transpiration agents on the market basically meet the demand and reduce the transpiration of plants to a certain extent. However, there are also many defects, such as: Thin-film anti-transpiration agents and reflective anti-transpiration agents need to be sprayed on the surface of plants to reduce transpiration through their isolation. Therefore, if the amount of spraying is too large, most of the stomata of the plants may be blocked, thereby affecting the vital energy of the plants. Photosynthesis and respiration hinder the absorption of oxygen and the discharge of carbon dioxide by plants. In addition, it is easy to be rained after spraying, so it has no effect

[0005] Compared with the above two transpirants, the metabotropic anti-transpiration agent is superior in effect and represents a development direction of a transpiration agent, but commonly used ones such as acetic acid Phenylmercury (PMA) is a kind of organic mercury, which is a lipophilic poison. Its residual drug effects can cause huge damage to the human body after inhalation, ingestion, and skin absorption. In addition, different plants have different effects on metabolic anti-transpiration agents. The types and concentration requirements are also different, making the selection of anti-transpiration agents very small
