Abstract

The invention provides a soybean weeding safener which comprises glucose, borax, 30% of hydrogen peroxide by mass percentage, zinc sulfate, ferrous sulfate heptahydrate, ammonium molybdate and diethylaminoethyl hexanoate. Glucose and borax are dissolved in water, and then ferrous sulfate heptahydrate (catalyst) is added, stirring is performed continuously and hydrogen peroxide is added for reaction, and then mother solution is obtained after reaction; zinc sulfate, ammonium molybdate and diethylaminoethyl hexanoate are sequentially slowly added into the mother solution, and stirring is performed continuously to obtain mixed solution; the water is added into the mixed solution to a constant volume to obtain the soybean weeding safener. The soybean weeding safener contains trace elements such as boron, zinc, iron and molybdenum needed by crops. Under the regulation effect of diethylaminoethyl hexanoate, full trace element nutrient can be provided for the crops, resistance of soybean to harm of a weed killer is improved, and the harm to soybean seedlings caused by the weed killer is avoided when the weed killer fomesafen is sprayed in soybean fields.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a soybean herbicide safener and a preparation method thereof. Background technique [0002] At present, herbicides have been widely used in agricultural production. The wide application of herbicides plays an important role in reducing costs, reducing labor intensity and improving agricultural benefits in modern agricultural production. Chemical weeding has become an important link in the production management of modern agriculture and has become a routine management technology of agricultural production. However, many types of herbicides often cause more or less phytotoxicity to crops in use, and cause great harm to agricultural production. For example, after the herbicide fomesafen (Tigerweir) commonly used in soybean fields is used, soybean seedlings are prone to phytotoxicity, yellow leaves, dry leaves, etc., which affect the growth and development of soybean seedlings.
