Description
Technical Field
The invention relates to the technical field of agriculture, in particular to an antitranspirant and a preparation method thereof.
Background
An antitranspirant is generally a substance which acts on the surface of plant leaves and can reduce the strength of transpiration, but has little influence on photosynthesis and growth. The antitranspirant is a novel drought-resistant technology, plays an important role in drought resistance, water conservation, disaster reduction and yield preservation in agricultural production, and can also be used for improving the survival rate of plant cuttage and transplantation, preventing burns caused by direct sun exposure in summer and the like. The antitranspirant can be divided into three categories according to different application mechanisms, namely a film type antitranspirant, a reflection type antitranspirant and a metabolic type antitranspirant. The active ingredient of the film-type antitranspirant is an organic macromolecular compound, and a soft and smooth film is formed on the leaf surface by spraying, so that the moisture diffused into the air through pores is greatly reduced; the reflection-type anti-transpiration agent can reflect partial solar radiation energy by being sprayed on the upper surface of the plant leaves, and the phenomenon that the leaves absorb the solar radiation is reduced, so that the temperature of the leaves is reduced, and the transpiration is reduced; the metabolic antitranspirant can close the air holes or reduce the opening of the air holes, thereby increasing the transpiration resistance of the air holes and inhibiting transpiration.
The conventional film type antitranspirant can increase the water potential of plant leaves and fruits, has good effects of improving crop yield, improving the survival rate of plant transplantation and cuttage, warming and moisturizing, resisting insect diseases, improving plant resistance and the like, is more effective than other two types of antitranspirants under the condition of short-term drought, and is widely applied to the fields of ornamental and greening tree species, big tree transplantation, fruit, vegetable and flower fresh keeping and the like. At present, the effective components of the film-type antitranspirant mainly comprise silicones, polyethylene, polyvinyl chloride, paraffin, turpentine diene and the like. Wherein the maltodextrin is a starch hydrolysate with DE value of 5-20, and is one of natural polymer materials with low price and good film forming performance. The chitosan quaternary ammonium salt is a pure natural extract product, has good antibacterial performance, and can improve the stress resistance of plants.
