Abstract

The invention discloses a non-cultivated-land compound herbicide suitable for controlling seedling weeds in greening gardens. The compound herbicide is prepared from raw materials in parts by weight as follows: 8-12 parts of cyhalofop-butyl, 5-10 parts of artemisia scoparia extract, 6-13 parts of chromolaena odorata extract, 1-7 parts of ambrosia artemisiifolia extract, 2-5 parts of wedelia chinensis extract, 1-4 parts of a thickening agent, 1-4 parts of a surfactant, 1-2 parts of a defoaming agent, 6-12 parts of polyvinyl alcohol, 3-7 parts of acetochlor emulsifiable concentrates, 1-2 parts of sodium benzoate, 1-4 parts of trichloroacetic acid and 1-3 parts of carboxymethyl cellulose. The garden herbicide is prepared with a special preparation method and can remove the weeds in the gardens without damage to ornamental seedlings in the gardens, and the extract of four plants including artemisia scoparia, chromolaena odorata, ambrosia artemisiifolia and wedelia chinensis is added, so that the compound herbicide is obvious in effect, natural, environmentally friendly and free of toxic and side effects and has the function of controlling various weeds in the gardens.

Description

technical field [0001] The invention relates to the field of garden weed control, in particular to a non-arable land compound herbicide suitable for afforesting garden seedlings and weeds. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, people's requirements for the living environment are getting higher and higher. Green gardens are increasingly valued by people because of their unique ecological benefits, landscape benefits and economic benefits. Greening garden seedlings are an important part of urban greening and landscape ecosystems. They are important standards for measuring urban ecological construction, landscaping level and per capita green area. They are used in many industries such as gardening, environmental protection, transportation, urban construction, sports and ecological governance. Assuming an important role, it is also an important material basis for maintaining ecological...
