Problems solved by technology

However, while covering agricultural mulch is beneficial to the growth of crops, it also creates conditions for the growth of weeds in the field. Weeds compete with crops for water, fertilizer and growth space, and it is difficult to remove weeds under the mulch. Spraying before mulching Herbicidal pesticides are time-consuming and labor-intensive, and will also cause damage to the ecological environment, and because the weeds have not yet grown, the effect is minimal

Abstract

The invention relates to an agricultural mulching film weed-killing master batch and a preparation method thereof. The agricultural mulching film weed-killing master batch comprises the following rawmaterials: a weed-killing agent, polyethylene, EVA, a stabilizer, a plasticizer, a slow-release agent, an antioxidant, a light stabilizer and the like. The weed-killing mulching film prepared from theagricultural mulching film weed killing master batch enriches the application functions of a common agricultural mulching film; besides the functions of warming and water retention, the weed killingand insect killing functions are achieved, a large amount of weed killing labor can be saved, the situation that weeds compete for water, fertilizer and growth space with crops is avoided due to the fact that young grass is killed when sprouting, and yield and income increase of the crops is effectively promoted. The weed-killing mulching film prepared from the agricultural mulching film weed-killing master batch has an excellent weed killing function, so that a large amount of labor for removing weeds in farmlands is saved, weed killing pesticides do not need to be sprayed to the farmlands, and the natural environment is protected.

Description

technical field [0001] The invention relates to the technical field of agricultural mulching film, in particular to an agricultural mulching film weed control masterbatch and a preparation method thereof. Background technique [0002] The agricultural mulch film produced by the blow molding process using polyethylene raw materials can cover crops, which can play the role of heat preservation, water retention and preventing fertilizer loss, and can promote the increase of crop production. However, while covering agricultural mulch is beneficial to the growth of crops, it also creates conditions for the growth of weeds in the field. Weeds compete with crops for water, fertilizer and growth space, and it is difficult to remove weeds under the mulch. Spraying before mulching Herbicidal pesticides are time-consuming and labor-intensive, and will also cause damage to the ecological environment, and because the weeds have not yet grown, the effect is minimal.
